virtual void BuildSignalWindow::SetStringParameters ( int  widget  )  const [inline, virtual]

Initialize string parameters for a widget.

Calls to this function are made during initialization to measure the size (that is as part of InitNested()), during drawing, and while re-initializing the window. Only for widgets that render text initializing is requested.

Parameters:
widget Widget number.
