@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 the tool bar.
|
|
|
|
<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(wxT("msw.remap"), 0);
|
|
@endcode
|
|
If you wish to use 32-bit images (which include an alpha channel for
|
|
transparency) use:
|
|
@code
|
|
wxSystemOptions::SetOption(wxT("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.
|
|
@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.
|
|
|
|
@beginEventTable{wxCommandEvent}
|
|
@event{EVT_TOOL(id, func)}
|
|
Process a @c wxEVT_COMMAND_TOOL_CLICKED event (a synonym for @c
|
|
wxEVT_COMMAND_MENU_SELECTED). 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_COMMAND_TOOL_CLICKED 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_COMMAND_TOOL_RCLICKED event. Pass the id of the
|
|
tool.
|
|
@event{EVT_TOOL_RCLICKED_RANGE(id1, id2, func)}
|
|
Process a @c wxEVT_COMMAND_TOOL_RCLICKED event for a range of ids. Pass
|
|
the ids of the tools.
|
|
@event{EVT_TOOL_ENTER(id, func)}
|
|
Process a @c wxEVT_COMMAND_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.
|
|
@event{EVT_TOOL_DROPDOWN(id, func)}
|
|
Process a @c wxEVT_COMMAND_TOOL_DROPDOWN_CLICKED 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.
