示例1:
bool
nsNativeTheme::IsFrameRTL(nsIFrame* aFrame)
{
if (!aFrame) {
return false;
}
WritingMode wm = aFrame->GetWritingMode();
return !(wm.IsVertical() ? wm.IsVerticalLR() : wm.IsBidiLTR());
}示例2: GetWritingModeName
explicit GetWritingModeName(const WritingMode& aWritingMode)
{
if (!aWritingMode.IsVertical()) {
Assign("Horizontal");
return;
}
if (aWritingMode.IsVerticalLR()) {
Assign("Vertical (LTR)");
return;
}
Assign("Vertical (RTL)");
