OnPaint |
Called when an element should be painted. Pixel values passed to this
method are scaled relative to view coordinates based on the value of
CefScreenInfo.device_scale_factor returned from GetScreenInfo. |type|
indicates whether the element is the view or the popup widget. |buffer|
contains the pixel data for the whole image. |dirtyRects| contains the set
of rectangles in pixel coordinates that need to be repainted. |buffer| will
be |width|*|height|*4 bytes in size and represents a BGRA image with an
