Add focusable box
MartinHowarth opened this issue · comments
This is a possible solution for #39. Some overlap with the z based event system issue as well.
This box has a focusable attribute. Only one box can be focused at once, and there is a global stack of focused ordering (e.g. one with current focus disappears, so the next one down gets focus automatically).
One way to take focus is by clicking on the box - c.f. overlapping windows.
Possible effects:
-
makes focused thing appear on top (high visual z index)
-
For any mouse event within the box, only it and it's children are allowed to handle them
-
need special case for drag event? Because can drag off the box, c.f. special handling in drag anchor
-
the focus box and its children get first dibs on keyboard events, but do not capture all of them
-
need to consider whether the children event handlers are removed from the global director event system if they are part of a focus group. This would stop them being called twice if the focus box handles passing the events down??
