DisplayServer¶
Inherits: Object
A server interface for low-level window management.
Description¶
DisplayServer handles everything related to window management. It is separated from OS as a single operating system may support multiple display servers.
Headless mode: Starting the engine with the --headless command line argument disables all rendering and window management functions. Most functions from DisplayServer will return dummy values in this case.

An active popup window will exclusively receive all input, without stealing focus from its parent. Popup windows are automatically closed when uses click outside it, or when an application is switched. Popup window must have transient parent set (see window_set_transient).
WindowFlags WINDOW_FLAG_EXTEND_TO_TITLE = 6
Window content is expanded to the full size of the window. Unlike borderless window, the frame is left intact and can be used to resize the window, title bar is transparent, but have minimize/maximize/close buttons.

Note: This flag is implemented only on macOS.
enum VSyncMode: 🔗

No vertical synchronization, which means the engine will display frames as fast as possible (tearing may be visible). Framerate is unlimited (regardless of Engine.max_fps).
VSyncMode VSYNC_ENABLED = 1
Default vertical synchronization mode, the image is displayed only on vertical blanking intervals (no tearing is visible). Framerate is limited by the monitor refresh rate (regardless of Engine.max_fps).
VSyncMode VSYNC_ADAPTIVE = 2
Behaves like VSYNC_DISABLED when the framerate drops below the screen's refresh rate to reduce stuttering (tearing may be visible). Otherwise, vertical synchronization is enabled to avoid tearing.

Note: Using third-party tools, it is possible for users to disable window geometry restrictions and therefore bypass this limit.
void window_set_mode(mode: WindowMode, window_id: int = 0) 🔗
Sets window mode for the given window to mode. See WindowMode for possible values and how each mode behaves.
Note: Setting the window to full screen forcibly sets the borderless flag to true, so make sure to set it back to false when not wanted.

# Set region, using Path2D node.
DisplayServer.window_set_mouse_passthrough($Path2D.curve.get_baked_points())
# Set region, using Polygon2D node.
DisplayServer.window_set_mouse_passthrough($Polygon2D.polygon)
# Reset region to default.
DisplayServer.window_set_mouse_passthrough([])
// Set region, using Path2D node.
DisplayServer.WindowSetMousePassthrough(GetNode<Path2D>("Path2D").Curve.GetBakedPoints());
// Set region, using Polygon2D node.
DisplayServer.WindowSetMousePassthrough(GetNode<Polygon2D>("Polygon2D").Polygon);
// Reset region to default.

* (0, 0) +-------+
| |
+-------------+ | |
| | | |
| | | |
+-------------+ +-------+
