## wxBitmapButton

A bitmap button is a control that contains a bitmap. It may be placed on a dialog box or panel, or indeed almost any other window.

Derived from

wxButton
wxControl
wxWindow
wxEvtHandler
wxObject

Include files

<wx/bmpbuttn.h>

Remarks

A bitmap button can be supplied with a single bitmap, and wxWindows will draw all button states using this bitmap. If the application needs more control, additional bitmaps for the selected state, unpressed focused state, and greyed-out state may be supplied.

Window styles

wxBU_AUTODRAW | If this is specified, the button will be drawn automatically using the label bitmap only, providing a 3D-look border. If this style is not specified, the button will be drawn without borders and using all provided bitmaps. WIN32 only.
wxBU_LEFT | Left-justifies the bitmap label. WIN32 only.
wxBU_TOP | Aligns the bitmap label to the top of the button. WIN32 only.
wxBU_RIGHT | Right-justifies the bitmap label. WIN32 only.
wxBU_BOTTOM | Aligns the bitmap label to the bottom of the button. WIN32 only.

See also window styles overview.

Event handling

EVT_BUTTON(id, func) | Process a wxEVT_COMMAND_BUTTON_CLICKED event, when the button is clicked.

### wxBitmapButton::wxBitmapButton

wxBitmapButton()

Default constructor.

wxBitmapButton( wxWindow* parent, wxWindowID id, const wxBitmap& bitmap, const wxPoint& pos = wxDefaultPosition, const wxSize& size = wxDefaultSize, long style = wxBU_AUTODRAW, const wxValidator& validator = wxDefaultValidator, const wxString& name = "button")

Constructor, creating and showing a button.

Parameters

parent

Parent window. Must not be NULL.

id

Button identifier. A value of -1 indicates a default value.

bitmap

Bitmap to be displayed.

pos

Button position.

size

Button size. If the default size (-1, -1) is specified then the button is sized appropriately for the bitmap.

style

Window style. See wxBitmapButton.

validator

Window validator.

name

Window name.

Remarks

The bitmap parameter is normally the only bitmap you need to provide, and wxWindows will draw the button correctly in its different states. If you want more control, call any of the functions wxBitmapButton::SetBitmapSelected, wxBitmapButton::SetBitmapFocus, wxBitmapButton::SetBitmapDisabled.

Note that the bitmap passed is smaller than the actual button created.
