- Protected Attributes inherited from z::Widget
float alpha_ = 1
 alpha value of widget. Widgets can be overlapped. Alpha value will be calculated in such cases.
 
bool hidden_ = false
 if hidden, a widget will not show on window, but still can react to event.
 
bool activated_ = true
 deactivated widget cannot get focus so that it cannot react to events.
 
bool focus_ = false
 
int zIndex_ = 0
 higher zIndex widget will be in front of lower zIndex widget.
