- /* A simple push button control with text in it, which is used to initiate an
- action.
- The exact appearence of an instance of a PTextButton is platform dependent.
- The implementation may not be completely orthoganal to other descendents of
- PPushButton. This is to yield maximum caompatibility with the native
- platforms button controls. For example, in MS-Windows the
- Ref{PPushButton::DrawButtonSurround()} and
- Ref{PPushButton::OnDrawFace()} functions are never actually called so the
- correct button is drawn. Thus if in a later version of the operating system
- the standard push buttons visual appearance is changed, PWLib applications
- will chane with it. Other button types such as Ref{PImageButtons} will
- remain as they were.
-
- A consequence of this is that the application should never descend from this
- class if the appearance is to be changed. Descend directly from PPushButton
- and draw the text contents. This could simply consist of the line:
- #canvas.DrawString(rect, GetName(), PCanvas::Centred);#
