Unigine.EngineWindow Class
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.
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
EngineWindowViewport window = new EngineWindowViewport("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 Size and ClientSize , 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., RenderSize , and so on). When the DPI scale is 100%, 1 unit corresponds to 1 pixel.
NoticeDPI 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:
- Use one of the ToRenderSize() or ToUnitSize() to convert the size.
- Use GlobalToLocalUnitPosition() to transform the coordinates in pixels into units or LocalUnitToGlobalPosition() to do the opposite.
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#)
EngineWindowViewport system_viewport;
private void Init()
{
// create a separate window viewport
system_viewport = new EngineWindowViewport("Separate System Viewport", 400, 350);
// specify an intial position
system_viewport.Position = new ivec2(30, 30);
// render the window viewport
system_viewport.Show();
}
private void Update()
{
// get the current mouse position
ivec2 mouse_pos = Input.MousePosition;
// change the window position to the mouse cursor when pressing 'P'
if (Input.IsKeyDown(Input.KEY.P))
{
if (system_viewport.IsDeleted == false)
system_viewport.Position = 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.ClientPosition = mouse_pos;
}
}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#)
EngineWindowViewport system_viewport;
EngineWindowViewport system_viewport_borderless;
EngineWindowViewport engine_viewport_borderless;
EngineWindowViewport engine_viewport;
private void Init()
{
// create a separate system viewport
system_viewport = new EngineWindowViewport("Window", 200, 200);
// specify an intial position
system_viewport.Position = new ivec2(30, 30);
// specify an intial size
system_viewport.Size = new ivec2(400, 350);
// render the window viewport
system_viewport.Show();
// create a separate system viewport with borders and title bar disabled
system_viewport_borderless = new EngineWindowViewport(400, 350);
system_viewport_borderless.Position = new ivec2(460, 30);
system_viewport_borderless.Size = new ivec2(400, 350);
// disable borders
system_viewport_borderless.BordersEnabled = false;
// disable a title bar
system_viewport_borderless.TitleBarEnabled = false;
system_viewport_borderless.Show();
// create a separate engine viewport with no borders
engine_viewport_borderless = new EngineWindowViewport("Window", 400, 350);
engine_viewport_borderless.Position = new ivec2(460, 30);
engine_viewport_borderless.EngineStyle = true;
engine_viewport_borderless.Size = new ivec2(400, 350);
// disable borders
engine_viewport_borderless.BordersEnabled = false;
engine_viewport_borderless.Show();
// create a separate engine viewport with borders
engine_viewport = new EngineWindowViewport("Window", 400, 350);
engine_viewport.Position = new ivec2(460, 30);
engine_viewport.EngineStyle = true;
engine_viewport.Size = new ivec2(400, 350);
engine_viewport.Show();
}|
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.
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#)
EngineWindow current_window;
EngineWindowViewport system_viewport;
EngineWindowViewport system_viewport_borderless;
EngineWindowViewport engine_viewport_borderless;
EngineWindowViewport engine_viewport;
private void Init()
{
// create a separate system viewport
system_viewport = new EngineWindowViewport("Window", 200, 200);
// specify an intial position
system_viewport.Position = new ivec2(30, 30);
// specify an intial size
system_viewport.Size = new ivec2(400, 350);
// render the window viewport
system_viewport.Show();
// create a separate system viewport with borders and title bar disabled
system_viewport_borderless = new EngineWindowViewport(400, 350);
system_viewport_borderless.Position = new ivec2(460, 30);
system_viewport_borderless.Size = new ivec2(400, 350);
// disable borders
system_viewport_borderless.BordersEnabled = false;
// disable a title bar
system_viewport_borderless.TitleBarEnabled = false;
system_viewport_borderless.Show();
// create a separate engine viewport with no borders
engine_viewport_borderless = new EngineWindowViewport("Window", 400, 350);
engine_viewport_borderless.Position = new ivec2(460, 30);
engine_viewport_borderless.EngineStyle = true;
engine_viewport_borderless.Size = new ivec2(400, 350);
// disable borders
engine_viewport_borderless.BordersEnabled = false;
engine_viewport_borderless.Show();
// create a separate engine viewport with borders
engine_viewport = new EngineWindowViewport("Window", 400, 350);
engine_viewport.Position = new ivec2(460, 30);
engine_viewport.EngineStyle = true;
engine_viewport.Size = new ivec2(400, 350);
engine_viewport.Show();
}
private void Update()
{
// get the current mouse position
ivec2 mouse_pos = Input.MousePosition;
// make the window under the cursor appear on top when pressing 'T'
if (Input.IsKeyDown(Input.KEY.T))
{
current_window = WindowManager.UnderCursorWindow;
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.UnderCursorWindow;
if (current_window.IsDeleted == false)
current_window.AlwaysOnTop = true;
}
}Changing Behavior#
With the set of behavior-related functions, you can do the following:
- Force the engine to stop operating while the engine window is opened.
- Ignore or allow using the OS methods for windows closing.
- Specify whether the window is resizable.
- Specify the sizing border size.
- Control rendering of the engine window - show, hide, focus, minimize, maximize, restore, or close.
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#)
WidgetLabel label;
EngineWindowViewport main_window;
private void Init()
{
// main window
main_window = WindowManager.MainWindow;
main_window.Size = new ivec2(1600, 900);
main_window.Position = new ivec2(30, 30);
main_window.CanBeNested = false;
main_window.CanCreateGroup = false;
// add an info label to the main window
label = new WidgetLabel("");
label.FontOutline = 1;
label.Lifetime = Widget.LIFETIME.WINDOW;
label.FontColor = vec4.RED;
main_window.AddChild(label, Gui.ALIGN_LEFT);
// first modal window of the main window
EngineWindowViewport main_modal_0 = new EngineWindowViewport("Modal for Main 0", 600, 650);
main_modal_0.Position = new ivec2(50, 250);
main_modal_0.CanBeNested = false;
main_modal_0.CanCreateGroup = false;
main_modal_0.Show();
main_modal_0.SetModal(main_window);
// second modal window of the main window
EngineWindowViewport main_modal_1 = new EngineWindowViewport("Modal for Main 1", 900, 650);
main_modal_1.Position = new ivec2(700, 250);
main_modal_1.CanBeNested = false;
main_modal_1.CanCreateGroup = false;
main_modal_1.Show();
main_modal_1.SetModal(main_window);
}
private void Update()
{
String text = "";
// check if the modal children of the main window are still opened
if (main_window.ModalParent == true)
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.Text = text;
