///////////////////////////////////////////////////////////////////////////// // Name: toolbar.h // Purpose: interface of wxToolBar // Author: wxWidgets team // RCS-ID: $Id$ // Licence: wxWindows license ///////////////////////////////////////////////////////////////////////////// /** @class wxToolBar The name wxToolBar is defined to be a synonym for one of the following classes: - @b wxToolBar95 - The native Windows 95 toolbar. Used on Windows 95, NT 4 and above. - @b wxToolBarMSW - A Windows implementation. Used on 16-bit Windows. - @b wxToolBarGTK - The GTK toolbar. You may also create a toolbar that is managed by the frame, by 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 a wxToolBar as usual. The meaning of a "separator" is a vertical line under Windows and simple space under GTK+. @b wxToolBar95: Note that this 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 There are several different types of tools you can add to a toolbar. These types are controlled by the ::wxItemKind enumeration. @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 Win32 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 -1 when the mouse moves off a tool, and -1 is not allowed as an identifier in the event system. @library{wxcore} @category{miscwnd} @see @ref overview_toolbar */ class wxToolBar : public wxControl { public: /** Default constructor. */ wxToolBar(); /** Constructs a toolbar. @param parent Pointer to a parent window. @param id Window identifier.
