I'm working on a widget and need to do calculations based on it's
height in order to layout its child components. So i do something like
this:
@Override
public void setHeight(String height) {
super.setHeight(height);
...do height calculations
}
The problem i'm having is that setHeight is called before the widget
is visible on the screen, and therefore, I can't do the calculation
because getOffsetHeight is equal to zero.
Is there a method I can override or an event I can subscribe to that
tells me when the widget is visible and has been laid out on the
screen, at which point i could run the calculation?
