virtual void BuildSignalWindow::DrawWidget ( const Rect r,
int  widget 
) const [inline, virtual]

Parameters:
r Rectangle occupied by the widget.
widget Number of the widget to draw.
Note:
This method may not change any state, it may only use drawing functions.

virtual void BuildSignalWindow::OnClick ( Point  pt,
int  widget,
int  click_count 
) [inline, virtual]

A click with the left mouse button has been made on the window.

Parameters:
pt the point inside the window that has been clicked.
widget the clicked widget.
click_count Number of fast consecutive clicks at same position

virtual void BuildSignalWindow::OnInvalidateData ( int  data = 0,
bool  gui_scope = true 
) [inline, virtual]

Some data on this window has become invalid.

Parameters:
data Information about the changed data.
gui_scope Whether the call is done from GUI scope. You may not do everything when not in GUI scope. See InvalidateWindowData() for details.

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.
