+ Disables the display of the text label in the button even if it has one

- Creates a flat button. Windows and GTK+ only.

SetBitmap() and SetBitmapLabel(), SetBitmapDisabled() &c methods. In the

now trivial) wxBitmapButton class which was only capable of showing an
image without text.
A button may have either a single image for all states or different images

The position of the image inside the button be configured using
SetBitmapPosition(). By default the image is on the left of the text.

The preferred way to create standard buttons is to use default value of
@a label. If no label is supplied and @a id is one of standard IDs from

+ @ref page_stockitems "this list", a standard label will be used. In

+ display any label at all and while wxButton will detect if the standard
+ "Help" label is used and ignore it, using any other label will prevent
+ the button from correctly appearing as a help button and so should be
+ avoided.

In addition to that, the button will be decorated with stock icons under GTK+ 2.
