virtual void	Start (CScreen *_screen)
	Just start the modal widget.
bool	IsRunning ()
	Must be invoked regularly (in each UI iteration), if Run() is not used.
virtual void	Stop ()
	Remove widget from screen (e.g. useful for inactivity timeout).
Status ...
int	GetStatus ()
	Get status: -2: running, -1: cancelled (e.g. by touching outside), >= 0: success, user-defined code set by 'SetStatus'.
void	SetStatus (int _status)
	Set a status code.
Behaviour for events outside the widget ...
void	SetNoCancelArea (SDL_Rect _rNoCancel)
	Set the no-cancel area. More...

Member Function Documentation

SetNoCancelArea()

void CModalWidget::SetNoCancelArea ( SDL_Rect  _rNoCancel )

inline

Set the no-cancel area.

     A touch outside this area is interpreted as a "cancel" operation. Normally and by default, this is equal
     to the area of this menu ('rFrame'), but there may be cases where this area needs to be extended,
     for example, if a combination of menus are presented simultaneously such as the month/year selector in the calendar app.
