or indeed on almost any other window.
- @beginStyleTable
- @style{wxBU_LEFT}
- Left-justifies the label. Windows and GTK+ only.
- @style{wxBU_TOP}
- Aligns the label to the top of the button. Windows and GTK+ only.
- @style{wxBU_RIGHT}
- Right-justifies the bitmap label. Windows and GTK+ only.
- @style{wxBU_BOTTOM}
- Aligns the label to the bottom of the button. Windows and GTK+ only.
- @style{wxBU_EXACTFIT}
- Creates the button as small as possible instead of making it of the
- standard size (which is the default behaviour ).
- @style{wxBU_NOTEXT}
- Disables the display of the text label in the button even if it has one
- or its id is one of the standard stock ids with an associated label:
- without using this style a button which is only supposed to show a
- bitmap but uses a standard id would display a label too.
- @style{wxBORDER_NONE}
- Creates a button without border. This is currently implemented in MSW,
- GTK2 and OSX/Carbon ports but in the latter only applies to buttons
- with bitmaps and using bitmap of one of the standard sizes only, namely
- 128*128, 48*48, 24*24 or 16*16. In all the other cases wxBORDER_NONE is
- ignored under OSX.

By default, i.e. if none of the alignment styles are specified, the label
is centered both horizontally and vertically. If the button has both a
label and a bitmap, the alignment styles above specify the location of the
bitmap with respect to the label (however currently non-default alignment
combinations are not implemented on all platforms).
- @beginEventEmissionTable{wxCommandEvent}
- @event{EVT_BUTTON(id, func)}
- Process a @c wxEVT_COMMAND_BUTTON_CLICKED event, when the button is clicked.

Since version 2.9.1 wxButton supports showing both text and an image
(currently only when using wxMSW, wxGTK or wxOSX/Cocoa ports), see
SetBitmap() and SetBitmapLabel(), SetBitmapDisabled() &c methods. In the
The position of the image inside the button be configured using
SetBitmapPosition(). By default the image is on the left of the text.
- Please also notice that GTK+ uses a global setting called @c
- gtk-button-images to determine if the images should be shown in the buttons
