示例1: Menu

TTeamMenuItem::DrawContentLabel()
{
	BMenu* menu = Menu();
	menu->MovePenBy(0, fLabelAscent);

	float cachedWidth = menu->StringWidth(Label());
	if (Submenu() && fVertical)
		cachedWidth += 18;

	const char* label = Label();
	char* truncLabel = NULL;
	float max = 0;

	if (fVertical && static_cast<TBarApp*>(be_app)->Settings()->superExpando)
		max = menu->MaxContentWidth() - kSwitchWidth;
	else
		max = menu->MaxContentWidth() - 4.0f;

	if (max > 0) {
		BPoint penloc = menu->PenLocation();
		BRect frame = Frame();
		float offset = penloc.x - frame.left;
		if (cachedWidth + offset > max) {
			truncLabel = (char*)malloc(strlen(label) + 4);
			if (!truncLabel)
				return;
			TruncateLabel(max-offset, truncLabel);
			label = truncLabel;
		}
	}

	if (!label)
		label = Label();

	TBarView* barview = (static_cast<TBarApp*>(be_app))->BarView();
