示例1:
void
nsGridRowLeafLayout::DirtyRows(nsIBox* aBox, nsBoxLayoutState& aState)
{
if (aBox) {
// mark us dirty
// XXXldb We probably don't want to walk up the ancestor chain
// calling MarkIntrinsicWidthsDirty for every row.
aState.PresShell()->FrameNeedsReflow(aBox, nsIPresShell::eTreeChange,
NS_FRAME_IS_DIRTY);
}
}示例2: rect
