wxWidgets/interface/wx/toolbar.h
Vadim Zeitlin ee2a2ccaee Fix return value of wxToolBar::GetToolBitmapSize() under GTK/Mac 
Fix another pixel units confusion in wxToolBar code and ensure that
"sizeNeeded" is expressed in logical units when a fixed bitmap size is
set, to make it consistent with the case when it is not set, and also
because bitmap size is supposed to be expressed in logical pixels, in
both SetToolBitmapSize() and, for consistency, GetToolBitmapSize() too.

Also explicitly mention the latter in the documentation.

See #23228, #23222.

popped up when the mouse pointer enters the tool and the long help string
for the applications status bar.
Notice that the toolbar can @e not be modified by changing its tools via

/**
@class wxToolBar
A toolbar is a bar of buttons and/or other controls usually placed below
the menu bar in a wxFrame.
You may create a toolbar that is managed by a frame calling
wxFrame::CreateToolBar(). Under Pocket PC, you should always use this
function for creating the toolbar to be managed by the frame, so that
wxWidgets can use a combined menubar and toolbar. Where you manage your
own toolbars, create wxToolBar as usual.
There are several different types of tools you can add to a toolbar.
These types are controlled by the ::wxItemKind enumeration.
Note that many methods in wxToolBar such as wxToolBar::AddTool return a
@c wxToolBarToolBase* object.
This should be regarded as an opaque handle representing the newly added
toolbar item, providing access to its id and position within the toolbar.
Changes to the item's state should be made through calls to wxToolBar methods,
for example wxToolBar::EnableTool.
Calls to @c wxToolBarToolBase methods (undocumented by purpose) will not change
the visible state of the item within the tool bar.
After you have added all the tools you need, you must call Realize() to
effectively construct and display the toolbar.
<b>wxMSW note</b>: Note that under wxMSW toolbar paints tools to reflect
system-wide colours. If you use more than 16 colours in your tool bitmaps,
you may wish to suppress this behaviour, otherwise system colours in your
bitmaps will inadvertently be mapped to system colours.
To do this, set the msw.remap system option before creating the toolbar:
@code
wxSystemOptions::SetOption("msw.remap", 0);
@endcode
If you wish to use 32-bit images (which include an alpha channel for
transparency) use:
@code
wxSystemOptions::SetOption("msw.remap", 2);
@endcode
Then colour remapping is switched off, and a transparent background
used. But only use this option under Windows XP with true colour:
@code
if (wxTheApp->GetComCtl32Version() >= 600 && ::wxDisplayDepth() >= 32)
@endcode
@beginStyleTable
@style{wxTB_FLAT}
Gives the toolbar a flat look (Windows and GTK only).
@style{wxTB_DOCKABLE}
Makes the toolbar floatable and dockable (GTK only).
@style{wxTB_HORIZONTAL}
Specifies horizontal layout (default).
@style{wxTB_VERTICAL}
Specifies vertical layout.
@style{wxTB_TEXT}
Shows the text in the toolbar buttons; by default only icons are shown.
@style{wxTB_NOICONS}
Specifies no icons in the toolbar buttons; by default they are shown.
@style{wxTB_NODIVIDER}
Specifies no divider (border) above the toolbar (Windows only)
@style{wxTB_NOALIGN}
Specifies no alignment with the parent window (Windows only, not very
useful).
@style{wxTB_HORZ_LAYOUT}
Shows the text and the icons alongside, not vertically stacked (Windows
and GTK 2 only). This style must be used with @c wxTB_TEXT.
@style{wxTB_HORZ_TEXT}
Combination of @c wxTB_HORZ_LAYOUT and @c wxTB_TEXT.
@style{wxTB_NO_TOOLTIPS}
Don't show the short help tooltips for the tools when the mouse hovers
over them.
@style{wxTB_BOTTOM}
Align the toolbar at the bottom of parent window.
@style{wxTB_RIGHT}
Align the toolbar at the right side of parent window.
@style{wxTB_DEFAULT_STYLE}
The @c wxTB_HORIZONTAL style. This style is new since wxWidgets 2.9.5.
@endStyleTable
See also @ref overview_windowstyles. Note that the wxMSW native toolbar
ignores @c wxTB_NOICONS style. Also, toggling the @c wxTB_TEXT works only
if the style was initially on.
@beginEventEmissionTable{wxCommandEvent}
@event{EVT_TOOL(id, func)}
Process a @c wxEVT_TOOL event (a synonym for @c
wxEVT_MENU). Pass the id of the tool.
@event{EVT_MENU(id, func)}
The same as EVT_TOOL().
@event{EVT_TOOL_RANGE(id1, id2, func)}
Process a @c wxEVT_TOOL event for a range of
identifiers. Pass the ids of the tools.
@event{EVT_MENU_RANGE(id1, id2, func)}
The same as EVT_TOOL_RANGE().
@event{EVT_TOOL_RCLICKED(id, func)}
Process a @c wxEVT_TOOL_RCLICKED event. Pass the id of the
tool. (Not available on wxOSX.)
@event{EVT_TOOL_RCLICKED_RANGE(id1, id2, func)}
Process a @c wxEVT_TOOL_RCLICKED event for a range of ids. Pass
the ids of the tools. (Not available on wxOSX.)
@event{EVT_TOOL_ENTER(id, func)}
Process a @c wxEVT_TOOL_ENTER event. Pass the id of the toolbar
itself. The value of wxCommandEvent::GetSelection() is the tool id, or
-1 if the mouse cursor has moved off a tool. (Not available on wxOSX.)
@event{EVT_TOOL_DROPDOWN(id, func)}
Process a @c wxEVT_TOOL_DROPDOWN event. If unhandled,
displays the default dropdown menu set using
wxToolBar::SetDropdownMenu().
@endEventTable
The toolbar class emits menu commands in the same way that a frame menubar
does, so you can use one EVT_MENU() macro for both a menu item and a toolbar
button. The event handler functions take a wxCommandEvent argument. For most
event macros, the identifier of the tool is passed, but for EVT_TOOL_ENTER()
the toolbar window identifier is passed and the tool identifier is retrieved
from the wxCommandEvent. This is because the identifier may be @c wxID_ANY when the
mouse moves off a tool, and @c wxID_ANY is not allowed as an identifier in the event
system.
