@page page_port Platform Details
|
|
|
|
wxWidgets defines a common API across platforms, but uses the native graphical
|
|
user interface (GUI) on each platform, so your program will take on the native
|
|
look and feel that users are familiar with. Unfortunately native toolkits and
|
|
hardware do not always support the functionality that the wxWidgets API
|
|
requires. This chapter collects notes about differences among supported platforms
|
|
and ports.

wxGTK is a port of wxWidgets using the GTK+ library.
|
|
It makes use of GTK+'s native widgets wherever possible and uses
|
|
wxWidgets' generic controls when needed. GTK+ itself has been
|
|
ported to a number of systems, but so far only the original X11
|
|
version is supported. Support for other GTK+ backends is planned,
|
|
such as the new DirectFB backend.
|
|
|
|
All work is being done on GTK+ version 2.0 and above. Support for
|
|
GTK+ 1.2 will be deprecated in a later release.
|
|
|
|
You will need GTK+ 2.6 or higher which is available from:
|
|
|
|
http://www.gtk.org
|
|
|
|
The newer version of GTK+ you use, the more native widgets and
|
|
features will be utilized. We have gone to great lengths to
|
|
allow compiling wxWidgets applications with the latest version of
|
|
GTK+, with the resulting binary working on systems even with a
|
|
much earlier version of GTK+. You will have to ensure that the
|
|
application is launched with lazy symbol binding for that.
|
|
|
|
In order to configure wxWidgets to compile wxGTK you will
|
|
need use the @c --with-gtk argument to the @c configure script.
|
|
This is the default for many systems.
|
|
|
|
GTK+ 1.2 can still be used, albeit discouraged. For that you can
|
|
pass @c --with-gtk=1 to the @c configure script.
|
|
|
|

|
|

@subsection page_port_wxosx_carbon wxOSX/Carbon
|
|
|
|
wxOSX/Carbon is a port of wxWidgets for the Macintosh OS platform.
|
|
Currently MacOS X 10.5 or higher are supported. wxOSX/Carbon can
|
|
be compiled both using Apple's command line developer tools
|
|
as well as Apple's Xcode IDE. wxOSX/Carbon supports both the Intel
|
|
and PowerPC architectures and can be used to produce
|
|
"universal binaries" in order create application which can run
|
|
both architecture. Unfortunately, wxOSX/Carbon does not support any
|
|
64-bit architecture since Apple decided not to port its Carbon
|
|
API entirely to 64-bit.
|
|
|
|
@note Carbon has been deprecated by Apple as of OS X 10.5 and will likely
|
|
be removed entirely in a future OS version. It's recommended you look into
|
|
switching your app over to wxOSX/Cocoa as soon as possible.
|
|
|
|
For further information, please see the files in @c docs/osx
|
|
in the distribution.
|
|
|
|
|
|
|
|
@subsection page_port_wxosx_cocoa wxOSX/Cocoa
|
|
|
|
wxOSX/Cocoa is another port of wxWidgets for the Macintosh OS
|
|
platform. Currently MacOS X 10.5 or higher are supported.
|
|
In contrast to wxOSX/Carbon, it uses the Cocoa API
|
|
in place of Carbon. Much work has gone into this port and many
|
|
controls are functional, but the port has not reached the maturity
|
|
of the wxOSX/Carbon port yet. It is possible to use wxOSX/Cocoa
|
|
on 64-bit architectures.
|
|
|
|
In order to configure wxWidgets to compile wxOSX/Cocoa you will
|
|
need to type:
|
|
|
|
@verbatim configure --with-osx_cocoa @endverbatim
|
|
|
|
For further information, please see the files in @c docs/osx
|
|
in the distribution.
|
|
|
|
@note There was a previous effort towards a Cocoa port called
|
|
wxCocoa, which was implemented totally with Cocoa API unlike the OSX/Cocoa port
|
|
which uses OS X C APIs to share code, and while it is no longer being actively
|
|
developed, docs for it are available in @c docs/cocoa in the distribution.

@section page_port_wxos2 wxOS2
|
|
|
|
wxOS2 is a port of wxWidgets for the IBM OS/2 Warp3 and Warp4 platforms.
|
|
This port is currently under construction and in beta phase.
|

|
|
|
|
wxX11 is a port of wxWidgets using X11 (The X Window System)
|
|
as the underlying graphics backend. wxX11 draws its widgets
|
|
using the wxUniversal widget set which is now part of wxWidgets.
|
|
wxX11 is well-suited for a number of special applications such
|
|
as those running on systems with few resources (PDAs) or for
|
|
applications which need to use a special themed look.
|
|
|
|
In order to configure wxWidgets to compile wxX11 you will
|
|
need to type:
|
|
|
|
@verbatim configure --with-x11 --with-universal @endverbatim
|
|
|
|
For further information, please see the files in @c docs/x11

wxMSW is a port of wxWidgets for the Windows platforms including Windows 95,
|
|
98, ME, 2000, NT, XP and Vista in ANSI and Unicode modes (for Windows 9x and
|
|
ME through the MSLU extension library). wxMSW ensures native look and feel for
|
|
XP when using wxWidgets version 2.3.3 or higher.wxMSW can be compiled with a
|
|
great variety of compilers including Microsoft Studio VC++, Borland 5.5,
|
|
MinGW32, Cygwin and Watcom as well as cross-compilation with a Linux-hosted
|
|
MinGW32 tool chain.

@subsection page_port_wxmsw_themedborders Themed borders on Windows
|
|
|
|
Starting with wxWidgets 2.8.5, you can specify the @c wxBORDER_THEME style to have wxWidgets
|
|
use a themed border. Using the default XP theme, this is a thin 1-pixel blue border,
|
|
with an extra 1-pixel border in the window client background colour (usually white) to
|
|
separate the client area's scrollbars from the border.
|
|
|
|
If you don't specify a border style for a wxTextCtrl in rich edit mode, wxWidgets now gives
|
|
the control themed borders automatically, where previously they would take the Windows 95-style
|
|
sunken border. Other native controls such as wxTextCtrl in non-rich edit mode, and wxComboBox
|
|
already paint themed borders where appropriate. To use themed borders on other windows, such
|
|
as wxPanel, pass the @c wxBORDER_THEME style, or (apart from wxPanel) pass no border style.
|
|
|
|
In general, specifying @c wxBORDER_THEME will cause a border of some kind to be used, chosen by the platform
|
|
and control class. To leave the border decision entirely to wxWidgets, pass @c wxBORDER_DEFAULT.
|
|
This is not to be confused with specifying @c wxBORDER_NONE, which says that there should
|
|
definitely be @e no border.
|
|
|
|
@subsubsection page_port_wxmsw_themedborders_details More detail on border implementation
|
|
|
|
The way that wxMSW decides whether to apply a themed border is as follows.
|
|
The theming code calls wxWindow::GetBorder() to obtain a border. If no border style has been
|
|
passed to the window constructor, GetBorder() calls GetDefaultBorder() for this window.
|
|
If wxBORDER_THEME was passed to the window constructor, GetBorder() calls GetDefaultBorderForControl().
|
|
|
|
The implementation of wxWindow::GetDefaultBorder() on wxMSW calls wxWindow::CanApplyThemeBorder()
|
|
which is a virtual function that tells wxWidgets whether a control can have a theme
|
|
applied explicitly (some native controls already paint a theme in which case we should not
|
|
apply it ourselves). Note that wxPanel is an exception to this rule because in many cases
|
|
we wish to create a window with no border (for example, notebook pages). So wxPanel
|
|
overrides GetDefaultBorder() in order to call the generic wxWindowBase::GetDefaultBorder(),
|
|
returning wxBORDER_NONE.
|
|
|
|
@subsection page_port_wxmsw_wince wxWinCE
|
|
|
|
wxWinCE is the name given to wxMSW when compiled on Windows CE devices;
|
|
most of wxMSW is common to Win32 and Windows CE but there are
|
|
some simplifications, enhancements, and differences in
|
|
behaviour.
|
|
|
|
For building instructions, see docs/msw/wince in the
|
|
distribution, also the section about Visual Studio 2005 project
|
|
files below. The rest of this section documents issues you
|
|
need to be aware of when programming for Windows CE devices.
|
|
|
|
@subsubsection page_port_wxmsw_wince_ General issues for wxWinCE programming
|
|
|
|
Mobile applications generally have fewer features and
|
|
simpler user interfaces. Simply omit whole sizers, static
|
|
lines and controls in your dialogs, and use comboboxes instead
|
|
of listboxes where appropriate. You also need to reduce
|
|
the amount of spacing used by sizers, for which you can
|
|
use a macro such as this:
|
|
|
|
@code
|
|
#if defined(__WXWINCE__)
|
|
#define wxLARGESMALL(large,small) small
|
|
#else
|
|
#define wxLARGESMALL(large,small) large
|
|
#endif
|
|
|
|
// Usage
|
|
topsizer->Add( CreateTextSizer( message ), 0, wxALL, wxLARGESMALL(10,0) );
|
|
@endcode
|
|
|
|
There is only ever one instance of a Windows CE application running,
|
|
and wxWidgets will take care of showing the current instance and
|
|
shutting down the second instance if necessary.
|
|
|
|
You can test the return value of wxSystemSettings::GetScreenType()
|
|
for a qualitative assessment of what kind of display is available,
|
|
or use wxGetDisplaySize() if you need more information.
|
|
|
|
You can also use wxGetOsVersion to test for a version of Windows CE at
|
|
run-time (see the next section). However, because different builds
|
|
are currently required to target different kinds of device, these
|
|
values are hard-wired according to the build, and you cannot
|
|
dynamically adapt the same executable for different major Windows CE
|
|
platforms. This would require a different approach to the way
|
|
wxWidgets adapts its behaviour (such as for menubars) to suit the
|
|
style of device.
|
|
|
|
See the "Life!" example (demos/life) for an example of
|
|
an application that has been tailored for PocketPC and Smartphone use.
|
|
|
|
@note don't forget to have this line in your .rc file, as for
|
|
desktop Windows applications:
|
|
|
|
@verbatim #include "wx/msw/wx.rc" @endverbatim
|
|
|
|
@subsubsection page_port_wxmsw_wince_sdk Testing for WinCE SDKs
|
|
|
|
Use these preprocessor symbols to test for the different types of device or SDK:
|
|
|
|
@li @b __SMARTPHONE__ Generic mobile devices with phone buttons and a small display
|
|
@li @b __PDA__ Generic mobile devices with no phone
|
|
@li @b __HANDHELDPC__ Generic mobile device with a keyboard
|
|
@li @b __WXWINCE__ Microsoft-powered Windows CE devices, whether PocketPC, Smartphone or Standard SDK
|
|
@li @b WIN32_PLATFORM_WFSP Microsoft-powered smartphone
|
|
@li @b __POCKETPC__ Microsoft-powered PocketPC devices with touch-screen
|
|
@li @b __WINCE_STANDARDSDK__ Microsoft-powered Windows CE devices, for generic Windows CE applications
|
|
@li @b __WINCE_NET__ Microsoft-powered Windows CE .NET devices (_WIN32_WCE is 400 or greater)
|
|
|
|
wxGetOsVersion will return these values:
|
|
|
|
@li @b wxWINDOWS_POCKETPC The application is running under PocketPC.
|
|
@li @b wxWINDOWS_SMARTPHONE The application is running under Smartphone.
|
|
@li @b wxWINDOWS_CE The application is running under Windows CE (built with the Standard SDK).
|
|
|
|
|
|
@subsubsection page_port_wxmsw_wince_sizing Window sizing in wxWinCE
|
|
|
|
Top level windows (dialogs, frames) are created always full-screen. Fit() of sizers will not rescale top
|
|
level windows but instead will scale window content.
|
|
|
|
If the screen orientation changes, the windows will automatically be resized
|
|
so no further action needs to be taken (unless you want to change the layout
|
|
according to the orientation, which you could detect in idle time, for example).
|
|
When input panel (SIP) is shown, top level windows (frames and dialogs) resize
|
|
accordingly (see wxTopLevelWindow::HandleSettingChange()).
|
|
|
|
@subsubsection page_port_wxmsw_wince_toplevel Closing top-level windows in wxWinCE
|
|
|
|
You won't get a wxCloseEvent when the user clicks on the X in the titlebar
|
|
on Smartphone and PocketPC; the window is simply hidden instead. However the system may send the
|
|
event to force the application to close down.
|
|
|
|
@subsubsection page_port_wxmsw_wince_hibernation Hibernation in wxWinCE
|
|
|
|
Smartphone and PocketPC will send a @c wxEVT_HIBERNATE to the application object in low
|
|
memory conditions. Your application should release memory and close dialogs,
|
|
and wake up again when the next @c wxEVT_ACTIVATE or @c wxEVT_ACTIVATE_APP message is received.
|
|
(@c wxEVT_ACTIVATE_APP is generated whenever a @c wxEVT_ACTIVATE event is received
|
|
in Smartphone and PocketPC, since these platforms do not support @c WM_ACTIVATEAPP.)
|
|
|
|
@subsubsection page_port_wxmsw_wince_hwbutt Hardware buttons in wxWinCE
|
|
|
|
Special hardware buttons are sent to a window via the @c wxEVT_HOTKEY event
|
|
under Smartphone and PocketPC. You should first register each required button with
|
|
wxWindow::RegisterHotKey(), and unregister the button when you're done with it. For example:
|
|
|
|
@code
|
|
win->RegisterHotKey(0, wxMOD_WIN, WXK_SPECIAL1);
|
|
win->UnregisterHotKey(0);
|
|
@endcode
|
|
|
|
You may have to register the buttons in a @c wxEVT_ACTIVATE event handler
|
|
since other applications will grab the buttons.
|
|
|
|
There is currently no method of finding out the names of the special
|
|
buttons or how many there are.
|
|
|
|
@subsubsection page_port_wxmsw_wince_dialogs Dialogs in wxWinCE
|
|
|
|
PocketPC dialogs have an OK button on the caption, and so you should generally
|
|
not repeat an OK button on the dialog. You can add a Cancel button if necessary, but some dialogs
|
|
simply don't offer you the choice (the guidelines recommend you offer an Undo facility
|
|
to make up for it). When the user clicks on the OK button, your dialog will receive
|
|
a @c wxID_OK event by default. If you wish to change this, call wxDialog::SetAffirmativeId()
|
|
with the required identifier to be used. Or, override wxDialog::DoOK() (return @false to
|
|
have wxWidgets simply call Close to dismiss the dialog).
|
|
|
|
Smartphone dialogs do @e not have an OK button on the caption, and are closed
|
|
using one of the two menu buttons. You need to assign these using wxTopLevelWindow::SetLeftMenu
|
|
and wxTopLevelWindow::SetRightMenu(), for example:
|
|
|
|
@code
|
|
#ifdef __SMARTPHONE__
|
|
SetLeftMenu(wxID_OK);
|
|
SetRightMenu(wxID_CANCEL, _("Cancel"));
|
|
#elif defined(__POCKETPC__)
|
|
// No OK/Cancel buttons on PocketPC, OK on caption will close
|
|
#else
|
|
topsizer->Add( CreateButtonSizer( wxOK|wxCANCEL ), 0, wxEXPAND | wxALL, 10 );
|
|
#endif
|
|
@endcode
|
|
|
|
For implementing property sheets (flat tabs), use a wxNotebook with @c wxNB_FLAT|wxNB_BOTTOM
|
|
and have the notebook left, top and right sides overlap the dialog by about 3 pixels
|
|
to eliminate spurious borders. You can do this by using a negative spacing in your
|
|
sizer Add() call. The cross-platform property sheet dialog wxPropertySheetDialog is
|
|
provided, to show settings in the correct style on PocketPC and on other platforms.
|
|
|
|
Notifications (bubble HTML text with optional buttons and links) will also be
|
|
implemented in the future for PocketPC.
|
|
|
|
Modeless dialogs probably don't make sense for PocketPC and Smartphone, since
|
|
frames and dialogs are normally full-screen, and a modeless dialog is normally
|
|
intended to co-exist with the main application frame.
|
|
|
|
@subsubsection page_port_wxmsw_wince_ppc Menubars and toolbars in PocketPC
|
|
|
|
On PocketPC, a frame must always have a menubar, even if it's empty.
|
|
An empty menubar/toolbar is automatically provided for dialogs, to hide
|
|
any existing menubar for the duration of the dialog.
|
|
|
|
Menubars and toolbars are implemented using a combined control,
|
|
but you can use essentially the usual wxWidgets API; wxWidgets will combine the menubar
|
|
and toolbar. However, there are some restrictions:
|
|
|
|
@li You must create the frame's primary toolbar with wxFrame::CreateToolBar(),
|
|
because this uses the special wxToolMenuBar class (derived from wxToolBar)
|
|
to implement the combined toolbar and menubar. Otherwise, you can create and manage toolbars
|
|
using the wxToolBar class as usual, for example to implement an optional
|
|
formatting toolbar above the menubar as Pocket Word does. But don't assign
|
|
a wxToolBar to a frame using SetToolBar - you should always use CreateToolBar
|
|
for the main frame toolbar.
|
|
@li Deleting and adding tools to wxToolMenuBar after Realize is called is not supported.
|
|
@li For speed, colours are not remapped to the system colours as they are
|
|
in wxMSW. Provide the tool bitmaps either with the correct system button background,
|
|
or with transparency (for example, using XPMs).
|
|
@li Adding controls to wxToolMenuBar is not supported. However, wxToolBar supports
|
|
controls.
|
|
|
|
Unlike in all other ports, a wxDialog has a wxToolBar automatically created
|
|
for you. You may either leave it blank, or access it with wxDialog::GetToolBar()
|
|
and add buttons, then calling wxToolBar::Realize(). You cannot set or recreate
|
|
the toolbar.
|
|
|
|
@subsubsection page_port_wxmsw_wince_smart Menubars and toolbars in Smartphone
|
|
|
|
On Smartphone, there are only two menu buttons, so a menubar is simulated
|
|
using a nested menu on the right menu button. Any toolbars are simply ignored on
|
|
Smartphone.
|
|
|
|
@subsubsection page_port_wxmsw_wince_closing Closing windows in wxWinCE
|
|
|
|
The guidelines state that applications should not have a Quit menu item,
|
|
since the user should not have to know whether an application is in memory
|
|
or not. The close button on a window does not call the window's
|
|
close handler; it simply hides the window. However, the guidelines say that
|
|
the Ctrl+Q accelerator can be used to quit the application, so wxWidgets
|
|
defines this accelerator by default and if your application handles
|
|
wxID_EXIT, it will do the right thing.
|
|
|
|
@subsubsection page_port_wxmsw_wince_ctx Context menus in wxWinCE
|
|
|
|
To enable context menus in PocketPC, you currently need to call wxWindow::EnableContextMenu(),
|
|
a wxWinCE-only function. Otherwise the context menu event (wxContextMenuEvent) will
|
|
never be sent. This API is subject to change.
|
|
|
|
Context menus are not supported in Smartphone.
|
|
|
|
@subsubsection page_port_wxmsw_wince_ctrl Control differences on wxWinCE
|
|
|
|
These controls and styles are specific to wxWinCE:
|
|
|
|
@li wxTextCtrl The @c wxTE_CAPITALIZE style causes a CAPEDIT control to
|
|
be created, which capitalizes the first letter.
|
|
|
|
These controls are missing from wxWinCE:
|
|
|
|
@li MDI classes MDI is not supported under Windows CE.
|
|
@li wxMiniFrame Not supported under Windows CE.
|
|
|
|
Tooltips are not currently supported for controls, since on PocketPC controls with
|
|
tooltips are distinct controls, and it will be hard to add dynamic
|
|
tooltip support.
|
|
|
|
Control borders on PocketPC and Smartphone should normally be specified with
|
|
@c wxBORDER_SIMPLE instead of @c wxBORDER_SUNKEN. Controls will usually adapt
|
|
appropriately by virtue of their GetDefaultBorder() function, but if you
|
|
wish to specify a style explicitly you can use @c wxDEFAULT_CONTROL_BORDER
|
|
which will give a simple border on PocketPC and Smartphone, and the sunken border on
|
|
other platforms.
|
|
|
|
@subsubsection page_port_wxmsw_wince_help Online help in wxWinCE
|
|
|
|
You can use the help controller wxWinceHelpController which controls
|

@subsubsection page_port_wxmsw_wince_install Installing your PocketPC and Smartphone applications
|
|
|
|
To install your application, you need to build a CAB file using
|
|
the parameters defined in a special .inf file. The CabWiz program
|
|
in your SDK will compile the CAB file from the .inf file and
|
|
files that it specifies.
|
|
|
|
For delivery, you can simply ask the user to copy the CAB file to the
|
|
device and execute the CAB file using File Explorer. Or, you can
|
|
write a program for the desktop PC that will find the ActiveSync
|
|
Application Manager and install the CAB file on the device,
|
|
which is obviously much easier for the user.
|
|
|
|
Here are some links that may help.

@subsubsection page_port_wxmsw_wince_filedlg wxFileDialog in PocketPC
|
|
|
|
Allowing the user to access files on memory cards, or on arbitrary
|
|
parts of the filesystem, is a pain; the standard file dialog only
|
|
shows folders under My Documents or folders on memory cards
|
|
(not the system or card root directory, for example). This is
|
|
a known problem for PocketPC developers.
|
|
|
|
If you need a file dialog that allows access to all folders,
|
|
you can use wxGenericFileDialog instead. You will need to include
|
|
@c wx/generic/filedlgg.h.

|
@subsubsection page_port_wxmsw_wince_evc Embedded Visual C++ Issues
|
|
|
|
<b>Run-time type information</b>
|
|
|
|
If you wish to use runtime type information (RTTI) with eVC++ 4, you need to download
|
|
an extra library, @c ccrtrtti.lib, and link with it. At the time of
|
|
writing you can get it from here:
|
|
|
|
@verbatim
|
|
http://support.microsoft.com/kb/830482/en-us
|
|
@endverbatim
|
|
|
|
Otherwise you will get linker errors similar to this:
|
|
|
|
@verbatim
|
|
wxwince26d.lib(control.obj) : error LNK2001: unresolved external symbol "const type_info::`vftable'" (??_7type_info@@6B@)
|
|

|
<b>Windows Mobile 5.0 emulator</b>
|
|
|
|
Note that there is no separate emulator configuration for Windows Mobile 5.0: the
|
|
emulator runs the ARM code directly.
|
|
|
|
<b>Visual Studio 2005 project files</b>
|
|
|
|
Unfortunately, Visual Studio 2005, required to build Windows Mobile 5.0 applications,
|
|
doesn't do a perfect job of converting the project files from eVC++ format.
|
|
|
|
When you have converted the wxWidgets workspace, edit the configuration properties
|
|
for each configuration and in the Librarian, add a relative path ..\\..\\lib to
|
|
each library path. For example:
|
|
<tt>..\\$(PlatformName)\\$(ConfigurationName)\\wx_mono.lib</tt>.
|
|
|
|
Then, for a sample you want to compile, edit the configuration properties
|
|
and make sure
|
|
<tt>..\\..\\lib\\$(PlatformName)\\$(ConfigurationName)</tt>
|
|
is in the Linker/General/Additional Library Directories property.
|
|
Also change the Linker/Input/Additional Dependencies property to something like
|
|
<tt>coredll.lib wx_mono.lib wx_wxjpeg.lib wx_wxpng.lib wx_wxzlib.lib wx_wxexpat.lib
|
|
commctrl.lib winsock.lib wininet.lib</tt>
|
|
(since the library names in the wxWidgets workspace were changed by VS 2005).
|
|
|
|
Alternately, you could edit all the names to be identical to the original eVC++
|
|
names, but this will probably be more fiddly.

|
@subsubsection page_port_wxmsw_wince_issues Remaining issues
|
|
|
|
These are some of the remaining problems to be sorted out, and features
|
|
to be supported.
|
|
|
|
@li <b>Windows Mobile 5 issues.</b> It is not possible to get the HMENU for
|
|
the command bar on Mobile 5, so the menubar functions need to be rewritten
|
|
to get the individual menus without use of a menubar handle. Also the
|
|
new Mobile 5 convention of using only two menus (and no bitmap buttons) needs to be
|
|
considered.
|
|
@li <b>Sizer speed.</b> Particularly for dialogs containing notebooks,
|
|
layout seems slow. Some analysis is required.
|
|
@li <b>Notification boxes.</b> The balloon-like notification messages, and their
|
|
icons, should be implemented. This will be quite straightforward.
|
|
@li <b>SIP size.</b> We need to be able to get the area taken up by the SIP (input panel),
|
|
and the remaining area, by calling SHSipInfo. We also may need to be able to show and hide
|
|
the SIP programmatically, with SHSipPreference. See also the <em>Input Dialogs</em> topic in
|
|
the <em>Programming Windows CE</em> guide for more on this, and how to have dialogs
|
|
show the SIP automatically using the @c WC_SIPREF control.
|
|
@li <b>wxStaticBitmap.</b> The About box in the "Life!" demo shows a bitmap that is
|
|
the correct size on the emulator, but too small on a VGA Pocket Loox device.
|
|
@li <b>wxStaticLine.</b> Lines don't show up, and the documentation suggests that
|
|
missing styles are implemented with @c WM_PAINT.
|
|
@li <b>HTML control.</b> PocketPC has its own HTML control which can be used for showing
|
|
local pages or navigating the web. We should create a version of wxHtmlWindow that uses this
|
|
control, or have a separately-named control (wxHtmlCtrl), with a syntax as close as possible
|
|
to wxHtmlWindow.
|
|
@li <b>Tooltip control.</b> PocketPC uses special TTBUTTON and TTSTATIC controls for adding
|
|
tooltips, with the tooltip separated from the label with a double tilde. We need to support
|
|
this using SetToolTip.(Unfortunately it does not seem possible to dynamically remove the tooltip,
|
|
so an extra style may be required.)
|
|
@li <b>Focus.</b> In the wxPropertySheetDialog demo on Smartphone, it's not possible to navigate
|
|
between controls. The focus handling in wxWidgets needs investigation. See in particular
|
|
src/common/containr.cpp, and note that the default OnActivate handler in src/msw/toplevel.cpp
|
|
sets the focus to the first child of the dialog.
|
|
@li <b>OK button.</b> We should allow the OK button on a dialog to be optional, perhaps
|
|
by using @c wxCLOSE_BOX to indicate when the OK button should be displayed.
|
|
@li <b>Dynamic adaptation.</b> We should probably be using run-time tests more
|
|
than preprocessor tests, so that the same WinCE application can run on different
|
|
versions of the operating system.
|
|
@li <b>Modeless dialogs.</b> When a modeless dialog is hidden with the OK button, it doesn't restore the
|
|
frame's menubar. See for example the find dialog in the dialogs sample. However, the menubar is restored
|
|
if pressing Cancel (the window is closed). This reflects the fact that modeless dialogs are
|
|
not very useful on Windows CE; however, we could perhaps destroy/restore a modeless dialog's menubar
|
|
on deactivation and activation.
|
|
@li <b>Home screen plugins.</b> Figure out how to make home screen plugins for use with wxWidgets
|
|
applications (see http://www.codeproject.com/ce/CTodayWindow.asp for inspiration).
|
|
Although we can't use wxWidgets to create the plugin (too large), we could perhaps write
|
|
a generic plugin that takes registry information from a given application, with
|
|
options to display information in a particular way using icons and text from
|
|
a specified location.
|
|
@li <b>Further abstraction.</b> We should be able to abstract away more of the differences
|
|
between desktop and mobile applications, in particular for sizer layout.
|
|
@li <b>Dialog captions.</b> The blue, bold captions on dialogs - with optional help button -
|
|
should be catered for, either by hard-wiring the capability into all dialogs and panels,
|
|
or by providing a standard component and sizer.
|

@section page_port_nativedocs Documentation for the native toolkits
|
|
|
|
It's sometimes useful to interface directly with the underlying toolkit
|
|
used by wxWidgets to e.g. use toolkit-specific features.
|
|
In such case (or when you want to e.g. write a port-specific patch) it can be
|
|
necessary to use the underlying toolkit API directly:
|
|
|
|
- wxMSW port uses win32 API: see MSDN docs at http://msdn2.microsoft.com/en-us/library/ms649779.aspx
|
|
- wxGTK port uses GTK+ and other lower-level libraries; see
|
|
- GTK+ docs at http://library.gnome.org/devel/gtk/unstable/
|
|
- GDK docs at http://library.gnome.org/devel/gdk/unstable/
|
|

|
|
- GObject docs at http://library.gnome.org/devel/gobject/unstable/
|
|
- Pango docs at http://library.gnome.org/devel/pango/unstable/
|
|
- wxMac port uses the Carbon API: see Carbon docs at http://developer.apple.com/carbon
|
