As discussed on wx-dev. some fixes and improvements for Interprocess Communication (IPC), using DDE and TCP.
1. DDE buffers were using a global buffer
2. TCP buffers were allocated each time needed, and Request would have caused memory leaks had it been used.
Fixed these both by using a self-resizing buffer in wxConnectionBase. Changed samples and docs to reflect the improved (but backward compatible) internal buffer management. wxConnectionBase could (in future) use wxMemoryBuffer.
3. IPC sample had trouble closing, causing crash, when closing server using window X button.
Because it was (effectively) trying to delete a window in OnExit, when that window was already destroyed. Fixed by making IPCDialog and MyConnection remember if they'd destroyed each other. It's not elegant, but either the connection or the window could be deleted first.
4. Docs for wxDDE... and wxTCP... duplicated eachother, supposed to have same API. Some parts unclear.
Patch removes dde and tcp-specific files (including from tipc.tex and classes.tex), and explains how ipc.h selects for you which one to use based on platform. Some other misc clarifications.
6. Client sample was suffering apparent memory leak because of not deleting connection object, and had a hack in there to do that.
In fact this was due to the derived OnDisconnect not deleting itself, as it does in base class. Mentioned need to do it in docs, fixed sample so that it does.

This is a patch to wxTip Provider classes used by the "Tip of the day" dialog.
See wx-dev archives August 2002 for discussion of the functionality design.
It does 5 things:
-Support for comments inside the tips file. The pound character (#) is used, as recommended by Vadim.
-Allows optional easy translation support to tips, by marking them as translatable for gettext, by enclosing them in a _(""). Program will translate these tips at runtime from the active catalog.
-Blank lines or lines with just spaces are automatically skipped (I had to put this in, I keep wondering why I get blank tips sometimes and it is because the text file had a empty blank line at the end of the text file).
-There is a pluggable virtual function to preprocess to modify the tip in a derived class, in case something specialized is desired, such as variable expansion, etc, as recommended by Julian and Vadim.
-Now resets the tip counter if the previous tip is past the end of the file (ie you removed some tips, or changed tip files), as discussed on wx-dev.
This patch updates:
-The classes.
-The class documentation and the Tip-of-the-day topic overview documentation.
-The dialogs example, placing some new strings for the tips.txt file which demonstrate how to use the Tip-of-the-day features for in practice.

Changed wxGridCellEditor::GetString to use %f instead of %g to match
the Renderer, otherwise it would truncate/round the value to
m_precision significant digits instead of m_precision digits after the
decimal point.

The attached patch completely fixes the flicker problem when
creating combo boxes. It also will make it elementary to
remove flicker during the creation of other controls
(although all the other controls are flicker free, AFAIK).
It does this by adding an optional 'visible' parameter to
the internal MSWCreateControl method, whereby the caller can
create a control invisibly by default, perform some
complicated sizing calculations, and then finally show the
control before the Create finished.

Proposed fixes for the wxWindows joystick code under
MSW.
Some of these would be valid for other platforms, too.
Events for buttons are named wrong, docs say different.
Docs say EVT_JOY_BUTTON_DOWN and
EVT_JOY_BUTTON_UP,
but the code says EVT_JOY_DOWN and EVT_JOY_UP. I
suggest
changing the code to match the docs.
wxJoystick::GetNumberJoysticks() should be a static
member
function. Having to create a joystick object to see if there
are joysticks is silly.
Docs for GetNumberJoysticks() must be changed; it returns
the
number of potentially connected joysticks, not the number of
actually connected. Alternatively, GetNumberJoysticks() and
others must be rewritten to conform with documentation,
including
remapping of wxWindows sequential joystick ID's to match
MSW non-sequential joystick ID's.
dwSize is not set when joyGetPosEx() is called. SEVERE
ERROR.
Error return value from functions should not be a legal
return,
for instance, wxJoystick::GetPOVCTSPosition() returns 0
for error,
but this is a legal return value.
GetButtonState() supports only four (out of 32) buttons.
Also, should return as bitmap (LSB = button 1). (Win32
does this,
although not documented as such).

- This patch implements a generic notebook based mdi,
due to that wxMDIChildFrame could not derive from
wxFrame some things in the samples and in the docmdi
classes needed to be adjusted... basically this comes
down to not do (wxFrame *) but instead do
(wxMDIChildFrame *), or store a pointer to the frame in a
wxWindow* instead of a wxFrame variable...
- The main reason wxMDIChildFrame cannot derive from
wxFrame is that it would take to much platform specific
functions to be overwritten (= lot of ifdef's). This then
couldn't be called generic anymore, so that's why we
need to derive from wxPanel...
- Tested on/with:
1. wxMSW (I disabled the MSW MDI implementation to
be able to test it), tested it with the MDI sample,
docvwmdi sample and docview sample and also tested it
with wxWorkshop. (test = compile and run)
2. wxX11, tested with the same set wxWin samples as
the wxMSW test. I also compiled wxWorkshop with it,
but could not run wxWorkshop due to some issue not
related to the MDI implementation.
- How to apply:
* Apply the patch
* move mdig.cpp into wxWindows/src/generic/
* move mdig.h into wxWindows/include/wx/generic/
- Some extra things that still need to be done:
* File lists, project files should be updated to include
mdig.cpp (the patch only change this on wxX11)
* The configuration script should be updated.
* Maybe wxUSE_GENERIC_MDI_ARCHITECTURE also
should be added so it is only included when wanted...

This patch is a draft which successfully allows a wxArtProvider to serve out icons to bitmaps for XRC files.
The syntax to use a wxArtProvider bitmap is:
<bitmap stock_id="wxART_INFORMATION" stock_client="wxART_TOOLBAR">somefallbackicon.png</bitmap>
The bitmap is optional, and will only be used as a fallback image, if the wxArtProvider returned a wxNullBitmap for some reason.
The client attribute, if not specified, currently will be wxART_OTHER. Perhaps there should be a guessing heuristic of it being in a menu node to call wxART_MENU.
Usage of XRC resouces and wxArtProvider together can be seen in an updated /contrib/samples/xrc demo, which is a separate patch.
Search the wx-dev mailing lists for "wxArtProvider" and "XRC" for the full discussions on this feature's API design.
Applied patch [ 594932 ] Extended XRC XML resources sample
By Robert O'Connor (robertoconnor)
This is a more comprehensive introduction to how to get up and running using XRC in your new wxWindows project.
It describes both the basics (for new users) and advanced features. It consists of a demo of dialogs and frames loaded from XRC. Each dialog has a textctrl at the top of the dialog, which walks the new user through that feature.
There are 8 demos:
The 4 basic ones:
-A non-derived dialog, as typically used for an about dialog.
-A derived dialog that loads its resources from an XRC (a frequently-asked question on the mailing lists), and responds to some simple events, including the disable-another-control-via-EVT_UPDATE_UI that is another FAQ, and powerful and simple-to-use feature.
-A XRC reference "Controls" dialog, using a notebook. Each tab has a single control. All XRC handled widgets can be seen at a glance, and how to use them under XRC.
-An uncentered dialog, to demonstrate the easy use of <centered>1</centered> to automatically place a Dialog centered on its parent..
The 4 advanced ones:
-Embedding a custom class into an XRC dialog, by using the "unknown" class.
-Using wxArtProvider to use stock icons from within your your XRC resources.
-Using the platform attribute to selectively show a part of XRC based on the current OS.
-Runtime variable expansion (demo only. Not implemented at this time).
Also:
-The main frame is now demonstrated as being loaded as an XRC.
- The toolbar has longhelp tag demonstrated, and are hooked up to the same events as the menu to show how XRCID() works on the same tool and menuitem XRCID.
-Some custom icons for the demonstration were created, and put into the toolbar and menubar. A custom icon also for the demonstration.
-The example code has been put in 1 class per file (both .cpp and a matching .xrc), to make it much less confusing for a newcomer to figure out what class is what, expecially with all the wx macros for declaration and implementation.
