C++ (Cpp) hideSelection Examples

Example #1

File: hud.cpp Project: Supermanu/xoreos

void HUD::callbackActive(Widget &widget) {
	KotORBase::HUD::callbackActive(widget);

	if (widget.getTag().beginsWith("BTN_TARGET"))
		return;

	if (widget.getTag() == "LBL_CHAR1") {
		_module.setPartyLeaderByIndex(0);
		return;
	}

		_module.setPartyLeaderByIndex(2);
		return;
	}
	if (widget.getTag() == "LBL_CHAR3") {

		return;
	}

	hideSelection();
	_menu.showMenu(widget.getTag());
	sub(_menu);
	_module.updateFrameTimestamp();
