Attributes

Remarks

Called when the application needs to redraw the content of its surface, after it is resized or for some other reason. By not returning from here until the redraw is complete, you can ensure that the user will not see your surface in a bad state (at its new size before it has been correctly drawn that way). This will typically be preceeded by a call to #surfaceChanged.

As of O, #surfaceRedrawNeededAsync may be implemented to provide a non-blocking implementation. If #surfaceRedrawNeededAsync is not implemented, then this will be called instead.
