Unigine::WidgetHitTestArea Class

Header: #include <UnigineWidgets.h>
Inherits from: Widget

This class is used to define the widget area in engine-style windows and borderless system windows intersected by a user-controlled cursor. If the hit test area type is "resize", the system automatically changes the cursor shape, if the hit test area is draggable, the window can be dragged by clicking and dragging this area.

In the following example, the system borders of the main window are disabled and 2 custom drag areas are added. The first area is located at the top of the window and the second area is in its center. For demonstration purposes, the background is enabled for both areas.

AppSystemLogic.cpp

Source code (C++)
#include "AppSystemLogic.h"
#include <UnigineWindowManager.h>

using namespace Unigine;

int AppSystemLogic::init()
{

	// borderless main window
	EngineWindowViewportPtr main_window = WindowManager::getMainWindow();
	if (main_window)
	{
		// disable system borders
		main_window->setBordersEnabled(false);

		GuiPtr gui = main_window->getSelfGui();

		// add a drag area similar to title bar
		WidgetVBoxPtr top_drag_container = WidgetVBox::create(gui);
		main_window->addChild(top_drag_container);

		WidgetHitTestAreaPtr top_drag_area = WidgetHitTestArea::create(gui, EngineWindow::HITTEST_DRAGGABLE);
		top_drag_area->setHeight(25);
		top_drag_container->addChild(top_drag_area, Gui::ALIGN_EXPAND);

		top_drag_area->setBackground(1);
		top_drag_area->setBackgroundColor(Math::vec4_red);

		// add an extra drag area
		WidgetHitTestAreaPtr drag_area = WidgetHitTestArea::create(gui, EngineWindow::HITTEST_DRAGGABLE);
		drag_area->setWidth(512);
		drag_area->setHeight(256);
		main_window->addChild(drag_area, Gui::ALIGN_CENTER);

		drag_area->setBackground(1);
		drag_area->setBackgroundColor(Math::vec4_blue);
	}

	return 1;
}
