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()

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

id

pos

size

style

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()

Toolbar destructor.


wxToolBar::AddControl

bool AddControl(wxControl* control)

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

control


wxToolBar::AddSeparator

void AddSeparator()

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

kind

bitmap1

bitmap2

shortHelpString

longHelpString

clientData

tool

Remarks

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

See also

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

enable

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.

y

Return value

A pointer to a tool if a tool is found, or NULL otherwise.

Remarks

Used internally, and should not need to be used by the programmer.


wxToolBar::GetToolSize

wxSize GetToolSize()

Returns the size of a whole button, which is usually larger than a tool bitmap because of added 3D effects.

See also

wxToolBar::SetToolBitmapSize, wxToolBar::GetToolBitmapSize


wxToolBar::GetToolBitmapSize

wxSize GetToolBitmapSize()

Returns the size of bitmap that the toolbar expects to have. The default bitmap size is 16 by 15 pixels.

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

toggleDown

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

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

x

y

Remarks

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

wxToolBar::OnMouseEnter, wxToolBar::OnLeftClick


wxToolBar::Realize

bool Realize()

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)

void SetMargins(int x, int y)

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

Parameters

size

x

y

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.

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

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


wxToolBar::SetToolClientData

void SetToolClientData(int id, wxObject* clientData)

Sets the client data associated with the tool.
