Unigine::EngineWindow Class

Header: #include <UnigineWindowManager.h>

This base class operates with engine windows: their components, relations with other windows, size, position, visual representation and other features.

When you create a window viewport or a window group, the engine window is created.

The image below demonstrates the window components that can be controlled by the EngineWindow class methods.

Window components

To create the engine window, use one of the EngineWindowViewportor EngineWindowGroupclass constructors. For example:

Source code (C++)
// create an engine window of the specified size with the specified name
EngineWindowViewportPtr window = EngineWindowViewport::create("New window", 580, 300);

Then, by using methods of the EngineWindow class, you can specify the window appearance (for example, set a title, an icon, change opacity, add borders, and so on), and properties (whether the window can be nested, or whether it can become a group), define its style (system or engine), change the window state (whether it is shown/hidden, minimized/maximized, focused, etc.), manage window intersections and events.

Setting Up Position and Size#

In UNIGINE, the window size and position coordinates are measured in both units and pixels:

  • The size and position in units don't depend on the DPI scale and always remain the same. You can change the window and client area size via setSize and setClientSize , adjust the minimum and maximum size and set the window and client position via the corresponding methods. All of them work with units.
  • The size and position in pixels are calculated by multiplying the size in units by the current DPI scale. You can get it using one of the RenderSize-related methods/properties (e.g., getRenderSize , and so on). When the DPI scale is 100%, 1 unit corresponds to 1 pixel.

    Notice
    DPI scaling is applied only when the auto_dpi_scalingflag is enabled. You can check the current flag value via the console or by using WindowManager::isAutoDpiScaling .
    To determine how the OS handles the DPI scale, specify the DPI awareness mode.

You should consider this information when resizing textures, calculating mouse intersections, etc. The window size and position should be set individually, depending on the situation.

Notice
If necessary, you can convert the size and position coordinates from units to pixels and visa versa:

In the following example, the positions of the window and client area (in units) change to the mouse cursor when you press the P or C respectively:

Source code (C++)
#include <UnigineEngine.h>
#include <UnigineLogic.h>
#include <UnigineWindowManager.h>

using namespace Unigine;
using namespace Math;

EngineWindowViewportPtr system_viewport;

int AppSystemLogic::init()
{
	// create a separate window viewport
	system_viewport = EngineWindowViewport::create("Separate System Viewport", 400, 350);
	// specify an intial position
	system_viewport->setPosition(ivec2(30, 30));
	// render the window viewport
	system_viewport->show();

	return 1;
}

int AppSystemLogic::update()
{
	// get the current mouse position
	ivec2 mouse_pos = Input::getMousePosition();

	// change the window position to the mouse cursor when pressing 'P' 
	if (Input::isKeyDown(Input::KEY_P))
	{
		
		if (system_viewport.isDeleted() == false)
			system_viewport->setPosition(mouse_pos);
	}

	// change the client area position to the mouse cursor when pressing 'C' 
	if (Input::isKeyDown(Input::KEY_C))
	{
		if (system_viewport.isDeleted() == false)
			system_viewport->setClientPosition(mouse_pos);
	}

	return 1;
}

Check also the WindowSandbox and WindowSize samples — they print the full information on the window size and DPI.

Adjusting Visual Representation#

The window visual representation includes all available window parameters such as title and title bar, icon, borders, opacity, and window style (the engine or system one).

Here are some window examples:

Source code (C++)
#include <UnigineEngine.h>
#include <UnigineLogic.h>
#include <UnigineWindowManager.h>

EngineWindowViewportPtr system_viewport;
EngineWindowViewportPtr system_viewport_borderless;
EngineWindowViewportPtr engine_viewport_borderless;
EngineWindowViewportPtr engine_viewport;

int AppSystemLogic::init()
{
	// create a separate system viewport
	system_viewport = EngineWindowViewport::create("Window", 200, 200);
	// specify an intial position
	system_viewport->setPosition(ivec2(30, 30));
	// specify an intial size
	system_viewport->setSize(ivec2(400, 350));
	// render the window viewport
	system_viewport->show();

	// create a separate system viewport with borders and title bar disabled
	system_viewport_borderless = EngineWindowViewport::create(400, 350);
	system_viewport_borderless->setPosition(ivec2(460, 30));
	system_viewport_borderless->setSize(ivec2(400, 350));
	// disable borders
	system_viewport_borderless->setBordersEnabled(false);
	// disable a title bar
	system_viewport_borderless->setTitleBarEnabled(false);
	system_viewport_borderless->show();

	// create a separate engine viewport with no borders
	engine_viewport_borderless = EngineWindowViewport::create("Window", 400, 350);
	engine_viewport_borderless->setPosition(ivec2(460, 30));
	engine_viewport_borderless->setEngineStyle(true);
	engine_viewport_borderless->setSize(ivec2(400, 350));
	// disable borders
	engine_viewport_borderless->setBordersEnabled(false);
	engine_viewport_borderless->show();

	// create a separate engine viewport with borders
	engine_viewport = EngineWindowViewport::create("Window", 400, 350);
	engine_viewport->setPosition(ivec2(460, 30));
	engine_viewport->setEngineStyle(true);
	engine_viewport->setSize(ivec2(400, 350));
	engine_viewport->show();

	return 1;
}

A system-style window

A window (either system or engine style),
borders and title bar disabled

An engine-style window, borders disabled

An engine-style window, borders enabled

The system and engine style windows have the same component layout except the sizing border: in the engine style, it is in the visual part of the window.

The ability to customize the window style makes it possible to create a standard set of window settings for different systems and frameworks.

Check the WindowVisual sample in UNIGINE SDK for more details.

Setting Up Order#

In the following example, the order of the window under the cursor changes when you press the specific button: T to make the window appear on top of all other windows, A to always render the window above the other windows.

Source code (C++)
#include <UnigineEngine.h>
#include <UnigineLogic.h>
#include <UnigineWindowManager.h>

EngineWindowPtr current_window;

EngineWindowViewportPtr system_viewport;
EngineWindowViewportPtr system_viewport_borderless;
EngineWindowViewportPtr engine_viewport_borderless;
EngineWindowViewportPtr engine_viewport;

int AppSystemLogic::init()
{
	// create a separate system viewport
	system_viewport = EngineWindowViewport::create("Window", 200, 200);
	// specify an intial position
	system_viewport->setPosition(ivec2(30, 30));
	// specify an intial size
	system_viewport->setSize(ivec2(400, 350));
	// render the window viewport
	system_viewport->show();

	// create a separate system viewport with borders and title bar disabled
	system_viewport_borderless = EngineWindowViewport::create(400, 350);
	system_viewport_borderless->setPosition(ivec2(460, 30));
	system_viewport_borderless->setSize(ivec2(400, 350));
	// disable borders
	system_viewport_borderless->setBordersEnabled(false);
	system_viewport_borderless->show();

	// create a separate engine viewport with no borders
	engine_viewport_borderless = EngineWindowViewport::create("Window", 400, 350);
	engine_viewport_borderless->setPosition(ivec2(460, 30));
	engine_viewport_borderless->setEngineStyle(true);
	engine_viewport_borderless->setSize(ivec2(400, 350));
	// disable borders
	engine_viewport_borderless->setBordersEnabled(false);
	engine_viewport_borderless->show();

	// create a separate engine viewport with borders
	engine_viewport = EngineWindowViewport::create("Window", 400, 350);
	engine_viewport->setPosition(ivec2(460, 30));
	engine_viewport->setEngineStyle(true);
	engine_viewport->setSize(ivec2(400, 350));
	engine_viewport->show();

	return 1;
}

int AppSystemLogic::update()
{
	// get the current mouse position
	ivec2 mouse_pos = Input::getMousePosition();

	// make the window under the cursor appear on top when pressing 'T'
	if (Input::isKeyDown(Input::KEY_T)) 
	{
		current_window = WindowManager::getUnderCursorWindow();
		if (current_window.isDeleted() == false)
			current_window->toTop();
	}

	// set the window under the cursor to be always on top when pressing 'A'
	if (Input::isKeyDown(Input::KEY_A))
	{
		current_window = WindowManager::getUnderCursorWindow();
		if (current_window.isDeleted() == false)
			current_window->setAlwaysOnTop(true);
	}

	return 1;
}

Check the WindowBehavior and WindowSandbox samples in UNIGINE SDK for more details.

Working with Modal Windows#

The following example demonstrates how to create modal windows and add modal children to the main window. Additionally, the main window includes a message that informs the user whether they can close the window or not.

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

using namespace Unigine;
using namespace Math;

WidgetLabelPtr label;
EngineWindowViewportPtr main_window;

int AppSystemLogic::init()
{
	// main window
	main_window = WindowManager::getMainWindow();
	main_window->setSize(ivec2(1600, 900));
	main_window->setPosition(ivec2(30, 30));
	main_window->setCanBeNested(false);
	main_window->setCanCreateGroup(false);

	// add an info label to the main window
	label = WidgetLabel::create("");
	label->setFontOutline(1);
	label->setLifetime(Widget::LIFETIME_WINDOW);
	label->setFontColor(vec4_red);
	main_window->addChild(label, Gui::ALIGN_LEFT);

	// first modal window of the main window
	EngineWindowViewportPtr main_modal_0 = EngineWindowViewport::create("Modal for Main 0", 600, 650);
	main_modal_0->setPosition(ivec2(50, 250));
	main_modal_0->setCanBeNested(false);
	main_modal_0->setCanCreateGroup(false);
	main_modal_0->show();
	main_modal_0->setModal(main_window);

	// second modal window of the main window
	EngineWindowViewportPtr main_modal_1 = EngineWindowViewport::create("Modal for Main 1", 900, 650);
	main_modal_1->setPosition(ivec2(700, 250));
	main_modal_1->setCanBeNested(false);
	main_modal_1->setCanCreateGroup(false);
	main_modal_1->show();
	main_modal_1->setModal(main_window);

	return 1;
}

int AppSystemLogic::update()
{
	String text;
	
	// check if the modal children of the main window are still opened 
	if (main_window->isModalParent())
		text += "You CANNOT close this window. Please close modal children first.\n";
	else
		text += "You CAN close this window.\n";
	
	// render the info label
	label->setText(text);
	
	return 1;
}
