wxToolBar

The name wxToolBar is defined to be a synonym for one of the following classes:

Note that the base class wxToolBarBase defines automatic scrolling management functionality which is similar to wxScrolledWindow, so please refer to this class also.

Derived from

wxToolBarBase
wxControl
wxWindow
wxEvtHandler
wxObject

Include files

<wx/toolbar.h> (to allow wxWidgets to select an appropriate toolbar class)
<wx/tbarbase.h> (the base class)

Remarks

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+.

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:

  wxSystemOptions::SetOption(wxT("msw.remap"), 0);

If you wish to use 32-bit images (which include an alpha channel for transparency) use:

  wxSystemOptions::SetOption(wxT("msw.remap"), 2);

then colour remapping is switched off, and a transparent background used. But only use this option under Windows XP with true colour:

  (wxTheApp->GetComCtl32Version() >= 600 && ::wxDisplayDepth() >= 32)

Window styles

wxTB_FLAT Gives the toolbar a flat look (Windows and GTK only).
wxTB_DOCKABLE Makes the toolbar floatable and dockable (GTK only).
wxTB_HORIZONTAL Specifies horizontal layout (default).
wxTB_VERTICAL Specifies vertical layout.
wxTB_TEXT Shows the text in the toolbar buttons; by default only icons are shown.
wxTB_NOICONS Specifies no icons in the toolbar buttons; by default they are shown.
wxTB_NODIVIDER Specifies no divider (border) above the toolbar (Windows only).
wxTB_NOALIGN Specifies no alignment with the parent window (Windows only, not very useful).
wxTB_HORZ_LAYOUT Shows the text and the icons alongside, not vertically stacked (Windows and GTK 2 only). This style must be used with wxTB_TEXT.
wxTB_HORZ_TEXT Combination of wxTB_HORZ_LAYOUT and wxTB_TEXT.

See also window styles overview. Note that the Win32 native toolbar ignores wxTB_NOICONS style. Also, toggling the wxTB_TEXT works only if the style was initially on.

Event handling

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.

EVT_TOOL(id, func) Process a wxEVT_COMMAND_TOOL_CLICKED event (a synonym for wxEVT_COMMAND_MENU_SELECTED). Pass the id of the tool.
EVT_MENU(id, func) The same as EVT_TOOL.
EVT_TOOL_RANGE(id1, id2, func) Process a wxEVT_COMMAND_TOOL_CLICKED event for a range of identifiers. Pass the ids of the tools.
EVT_MENU_RANGE(id1, id2, func) The same as EVT_TOOL_RANGE.
EVT_TOOL_RCLICKED(id, func) Process a wxEVT_COMMAND_TOOL_RCLICKED event. Pass the id of the tool.
EVT_TOOL_RCLICKED_RANGE(id1, id2, func) Process a wxEVT_COMMAND_TOOL_RCLICKED event for a range of ids. Pass the ids of the tools.
EVT_TOOL_ENTER(id, func) Process a 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.

wxToolBar::wxToolBar



wxToolBar(void)

Default constructor.



wxToolBar(wxWindow* parent, wxWindowID id, const wxPoint& pos = wxDefaultPosition, const wxSize& size = wxDefaultSize, long style = wxTB_HORIZONTAL || wxNO_BORDER, const wxString& name = wxPanelNameStr)

Constructs a toolbar.

Parameters

parent
Pointer to a parent window.

id
Window identifier. If -1, will automatically create an identifier.

pos
Window position. wxDefaultPosition is (-1, -1) which indicates that wxWidgets should generate a default position for the window. If using the wxWindow class directly, supply an actual position.

size
Window size. wxDefaultSize is (-1, -1) which indicates that wxWidgets should generate a default size for the window.

style
Window style. See wxToolBar for details.

name
Window name.

Remarks

After a toolbar is created, you use wxToolBar::AddTool and perhaps wxToolBar::AddSeparator, and then you must call wxToolBar::Realize to construct and display the toolbar tools.

You may also create a toolbar that is managed by the frame, by calling wxFrame::CreateToolBar.



wxToolBar::~wxToolBar



void ~wxToolBar(void)

Toolbar destructor.



wxToolBar::AddControl



bool AddControl(wxControl* control)

Adds any control to the toolbar, typically e.g. a combobox.

control
The control to be added.



wxToolBar::AddSeparator



void AddSeparator(void)

Adds a separator for spacing groups of tools.

wxToolBar::AddTool, wxToolBar::SetToolSeparation



wxToolBar::AddTool



wxToolBarToolBase* AddTool(int toolId, const wxString& label, const wxBitmap& bitmap1, const wxString& shortHelpString = "", wxItemKind kind = wxITEM_NORMAL)



wxToolBarToolBase* AddTool(int toolId, const wxString& label, const wxBitmap& bitmap1, const wxBitmap& bitmap2 = wxNullBitmap, wxItemKind kind = wxITEM_NORMAL, const wxString& shortHelpString = "", const wxString& longHelpString = "", wxObject* clientData = NULL)



wxToolBarToolBase* AddTool(wxToolBarToolBase* tool)

Adds a tool to the toolbar. The first (short and most commonly used) version has fewer parameters than the full version at the price of not being able to specify some of the more rarely used button features. The last version allows you to add an existing tool.

Parameters

toolId
An integer by which the tool may be identified in subsequent operations.

kind
May be wxITEM_NORMAL for a normal button (default), wxITEM_CHECK for a checkable tool (such tool stays pressed after it had been toggled) or wxITEM_RADIO for a checkable tool which makes part of a radio group of tools each of which is automatically unchecked whenever another button in the group is checked

bitmap1
The primary tool bitmap.

bitmap2
The bitmap used when the tool is disabled. If it is equal to wxNullBitmap, the disabled bitmap is automatically generated by greing the normal one.

shortHelpString
This string is used for the tools tooltip

longHelpString
This string is shown in the statusbar (if any) of the parent frame when the mouse pointer is inside the tool

clientData
An optional pointer to client data which can be retrieved later using wxToolBar::GetToolClientData.

tool
The tool to be added.

Remarks

After you have added tools to a toolbar, you must call wxToolBar::Realize in order to have the tools appear.

wxToolBar::AddSeparator, wxToolBar::AddCheckTool, wxToolBar::AddRadioTool, wxToolBar::InsertTool, wxToolBar::DeleteTool, wxToolBar::Realize



wxToolBar::AddCheckTool



wxToolBarToolBase* AddCheckTool(int toolId, const wxString& label, const wxBitmap& bitmap1, const wxBitmap& bitmap2, const wxString& shortHelpString = "", const wxString& longHelpString = "", wxObject* clientData = NULL)

Adds a new check (or toggle) tool to the toolbar. The parameters are the same as in wxToolBar::AddTool.

See also

wxToolBar::AddTool



wxToolBar::AddRadioTool



wxToolBarToolBase* AddRadioTool(int toolId, const wxString& label, const wxBitmap& bitmap1, const wxBitmap& bitmap2, const wxString& shortHelpString = "", const wxString& longHelpString = "", wxObject* clientData = NULL)

Adds a new radio tool to the toolbar. Consecutive radio tools form a radio group such that exactly one button in the group is pressed at any moment, in other words whenever a button in the group is pressed the previously pressed button is automatically released. You should avoid having the radio groups of only one element as it would be impossible for the user to use such button.

By default, the first button in the radio group is initially pressed, the others are not.

wxToolBar::AddTool



wxToolBar::DeleteTool



bool DeleteTool(int toolId)

Removes the specified tool from the toolbar and deletes it. If you don't want to delete the tool, but just to remove it from the toolbar (to possibly add it back later), you may use RemoveTool instead.

Note that it is unnecessary to call Realize for the change to take place, it will happen immediately.

Returns true if the tool was deleted, false otherwise.

See also

DeleteToolByPos



wxToolBar::DeleteToolByPos



bool DeleteToolByPos(size_t pos)

This function behaves like DeleteTool but it deletes the tool at the specified position and not the one with the given id.



wxToolBar::EnableTool



void EnableTool(int toolId, const bool enable)

Enables or disables the tool.

Parameters

toolId
Tool to enable or disable.

enable
If true, enables the tool, otherwise disables it.

NB: This function should only be called after Realize.

Remarks

Some implementations will change the visible state of the tool to indicate that it is disabled.

wxToolBar::GetToolEnabled, wxToolBar::ToggleTool



wxToolBar::FindById



wxToolBarToolBase* FindById(int id)

Returns a pointer to the tool identified by id or NULL if no corresponding tool is found.

InsertSeparator



wxToolBar::OnLeftClick



bool OnLeftClick(int toolId, bool toggleDown)

Called when the user clicks on a tool with the left mouse button.

This is the old way of detecting tool clicks; although it will still work, you should use the EVT_MENU or EVT_TOOL macro instead.

Parameters

toolId
The identifier passed to wxToolBar::AddTool.

toggleDown
true if the tool is a toggle and the toggle is down, otherwise is false.

Return value

If the tool is a toggle and this function returns false, the toggle toggle state (internal and visual) will not be changed. This provides a way of specifying that toggle operations are not permitted in some circumstances.

See also

wxToolBar::OnMouseEnter, wxToolBar::OnRightClick



wxToolBar::OnMouseEnter



void OnMouseEnter(int toolId)

This is called when the mouse cursor moves into a tool or out of the toolbar.

This is the old way of detecting mouse enter events; although it will still work, you should use the EVT_TOOL_ENTER macro instead.

Parameters

toolId
Greater than -1 if the mouse cursor has moved into the tool, or -1 if the mouse cursor has moved. The programmer can override this to provide extra information about the tool, such as a short description on the status line.

Remarks

With some derived toolbar classes, if the mouse moves quickly out of the toolbar, wxWidgets may not be able to detect it. Therefore this function may not always be called when expected.



wxToolBar::OnRightClick



void OnRightClick(int toolId, float x, float y)

Called when the user clicks on a tool with the right mouse button. The programmer should override this function to detect right tool clicks.

This is the old way of detecting tool right clicks; although it will still work, you should use the EVT_TOOL_RCLICKED macro instead.

Parameters

toolId
The identifier passed to wxToolBar::AddTool.

x
The x position of the mouse cursor.

y
The y position of the mouse cursor.

Remarks

A typical use of this member might be to pop up a menu.

See also

wxToolBar::OnMouseEnter, wxToolBar::OnLeftClick



wxToolBar::Realize



bool Realize(void)

This function should be called after you have added tools.



wxToolBar::RemoveTool



wxToolBarToolBase * RemoveTool(int id)

Removes the given tool from the toolbar but doesn't delete it. This allows to insert/add this tool back to this (or another) toolbar later.

Note that it is unnecessary to call Realize for the change to take place, it will happen immediately.

See also

DeleteTool



wxToolBar::SetBitmapResource



void SetBitmapResource(int resourceId)

Sets the bitmap resource identifier for specifying tool bitmaps as indices into a custom bitmap. Windows CE only.



wxToolBar::SetMargins



void SetMargins(const wxSize& size)

Set the values to be used as margins for the toolbar.

Parameters

size
Margin size.

x
Left margin, right margin and inter-tool separation value.

y
Top margin, bottom margin and inter-tool separation value.

Remarks

This must be called before the tools are added if absolute positioning is to be used, and the default (zero-size) margins are to be overridden.

See also

wxToolBar::GetMargins, wxSize



wxToolBar::SetToolBitmapSize



void SetToolBitmapSize(const wxSize& size)

Sets the default size of each tool bitmap. The default bitmap size is 16 by 15 pixels.

Parameters

size
The size of the bitmaps in the toolbar.

Remarks

This should be called to tell the toolbar what the tool bitmap size is. Call it before you add tools.

Note that this is the size of the bitmap you pass to wxToolBar::AddTool, and not the eventual size of the tool button.

See also

wxToolBar::GetToolBitmapSize, wxToolBar::GetToolSize
