A server interface for low-level window management. [DisplayServer] handles everything related to window management. It is separated from [OS] as a single operating system may support multiple display servers. [b]Headless mode:[/b] Starting the engine with the [code]--headless[/code] [url=$DOCS_URL/tutorials/editor/command_line_tutorial.html]command line argument[/url] disables all rendering and window management functions. Most functions from [DisplayServer] will return dummy values in this case. Returns the user's clipboard as a string if possible. Returns the user's [url=https://unix.stackexchange.com/questions/139191/whats-the-difference-between-primary-selection-and-clipboard-buffer]primary[/url] clipboard as a string if possible. This is the clipboard that is set when the user selects text in any application, rather than when pressing [kbd]Ctrl + C[/kbd]. The clipboard data can then be pasted by clicking the middle mouse button in any application that supports the primary clipboard mechanism. [b]Note:[/b] This method is only implemented on Linux (X11). Returns [code]true[/code] if there is content on the user's clipboard. Sets the user's clipboard content to the given string. Sets the user's [url=https://unix.stackexchange.com/questions/139191/whats-the-difference-between-primary-selection-and-clipboard-buffer]primary[/url] clipboard content to the given string. This is the clipboard that is set when the user selects text in any application, rather than when pressing [kbd]Ctrl + C[/kbd]. The clipboard data can then be pasted by clicking the middle mouse button in any application that supports the primary clipboard mechanism. [b]Note:[/b] This method is only implemented on Linux (X11). Returns the default mouse cursor shape set by [method cursor_set_shape]. Sets a custom mouse cursor image for the defined [param shape]. This means the user's operating system and mouse cursor theme will no longer influence the mouse cursor's appearance. The image must be [code]256x256[/code] or smaller for correct appearance. [param hotspot] can optionally be set to define the area where the cursor will click. By default, [param hotspot] is set to [code]Vector2(0, 0)[/code], which is the top-left corner of the image. See also [method cursor_set_shape]. Sets the default mouse cursor shape. The cursor's appearance will vary depending on the user's operating system and mouse cursor theme. See also [method cursor_get_shape] and [method cursor_set_custom_image]. Shows a text input dialog which uses the operating system's native look-and-feel. [param callback] will be called with a [String] argument equal to the text field's contents when the dialog is closed for any reason. [b]Note:[/b] This method is implemented only on macOS. Shows a text dialog which uses the operating system's native look-and-feel. [param callback] will be called when the dialog is closed for any reason. [b]Note:[/b] This method is implemented only on macOS. Allows the [param process_id] PID to steal focus from this window. In other words, this disables the operating system's focus stealing protection for the specified PID. [b]Note:[/b] This method is implemented only on Windows. Forces window manager processing while ignoring all [InputEvent]s. See also [method process_events]. [b]Note:[/b] This method is implemented on Windows and macOS. Returns OS theme accent color. Returns [code]Color(0, 0, 0, 0)[/code], if accent color is unknown. [b]Note:[/b] This method is implemented on macOS and Windows. Returns an [Array] of [Rect2], each of which is the bounding rectangle for a display cutout or notch. These are non-functional areas on edge-to-edge screens used by cameras and sensors. Returns an empty array if the device does not have cutouts. See also [method get_display_safe_area]. [b]Note:[/b] Currently only implemented on Android. Other platforms will return an empty array even if they do have display cutouts or notches. Returns the unobscured area of the display where interactive controls should be rendered. See also [method get_display_cutouts]. Returns the index of the screen containing the window with the keyboard focus, or the primary screen if there's no focused window. Returns the name of the [DisplayServer] currently in use. Most operating systems only have a single [DisplayServer], but Linux has access to more than one [DisplayServer] (although only X11 is currently implemented in Godot). The names of built-in display servers are [code]Windows[/code], [code]macOS[/code], [code]X11[/code] (Linux), [code]Android[/code], [code]iOS[/code], [code]web[/code] (HTML5) and [code]headless[/code] (when started with the [code]--headless[/code] [url=$DOCS_URL/tutorials/editor/command_line_tutorial.html]command line argument[/url]). Returns index of the primary screen. Returns the number of displays available. Returns index of the screen which contains specified rectangle. Returns [code]true[/code] if positions of [b]OK[/b] and [b]Cancel[/b] buttons are swapped in dialogs.

Sets the minimum size for the given window to [param min_size] (in pixels). Normally, the user will not be able to drag the window to make it larger than the specified size. See also [method window_get_min_size]. [b]Note:[/b] It's recommended to change this value using [member Window.min_size] instead. [b]Note:[/b] By default, the main window has a minimum size of [code]Vector2i(64, 64)[/code]. This prevents issues that can arise when the window is resized to a near-zero size. [b]Note:[/b] Using third-party tools, it is possible for users to disable window geometry restrictions and therefore bypass this limit. Sets window mode for the given window to [param mode]. See [enum WindowMode] for possible values and how each mode behaves. [b]Note:[/b] Setting the window to full screen forcibly sets the borderless flag to [code]true[/code], so make sure to set it back to [code]false[/code] when not wanted. Sets a polygonal region of the window which accepts mouse events. Mouse events outside the region will be passed through. Passing an empty array will disable passthrough support (all mouse events will be intercepted by the window, which is the default behavior). [codeblocks] [gdscript] # Set region, using Path2D node.

Normally happens when the maximize button is pressed. Full screen mode with full multi-window support. Full screen window cover the entire display area of a screen, have no border or decorations. Display video mode is not changed. [b]Note:[/b] Regardless of the platform, enabling full screen will change the window size to match the monitor's size. Therefore, make sure your project supports [url=$DOCS_URL/tutorials/rendering/multiple_resolutions.html]multiple resolutions[/url] when enabling full screen mode. A single window full screen mode. This mode has less overhead, but only one window can be open on a given screen at a time (opening a child window or application switching will trigger a full screen transition). Full screen window cover the entire display area of a screen, have no border or decorations. Display video mode is not changed. [b]On Windows:[/b] Depending on video driver, full screen transition might cause screens to go black for a moment. [b]On macOS:[/b] Exclusive full screen mode prevents Dock and Menu from showing up when the mouse pointer is hovering the edge of the screen. [b]On Linux (X11):[/b] Exclusive full screen mode bypasses compositor. [b]Note:[/b] Regardless of the platform, enabling full screen will change the window size to match the monitor's size. Therefore, make sure your project supports [url=$DOCS_URL/tutorials/rendering/multiple_resolutions.html]multiple resolutions[/url] when enabling full screen mode. The window can't be resized by dragging its resize grip. It's still possible to resize the window using [method window_set_size]. This flag is ignored for full screen windows. The window do not have native title bar and other decorations. This flag is ignored for full-screen windows. The window is floating on top of all other windows. This flag is ignored for full-screen windows. The window background can be transparent. [b]Note:[/b] This flag has no effect if [member ProjectSettings.display/window/per_pixel_transparency/allowed] is set to [code]false[/code]. [b]Note:[/b] Transparency support is implemented on Linux (X11), macOS and Windows, but availability might vary depending on GPU driver, display manager, and compositor capabilities. The window can't be focused. No-focus window will ignore all input, except mouse clicks. Window is part of menu or [OptionButton] dropdown. This flag can't be changed when the window is visible. 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 [method window_set_transient]). 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. Use [method window_set_window_buttons_offset] to adjust minimize/maximize/close buttons offset. Use [method window_get_safe_title_margins] to determine area under the title bar that is not covered by decorations. [b]Note:[/b] This flag is implemented only on macOS.

[b]Note:[/b] This flag is implemented only on macOS. No vertical synchronization, which means the engine will display frames as fast as possible (tearing may be visible). Framerate is unlimited (notwithstanding [member Engine.max_fps]). 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 (notwithstanding [member Engine.max_fps]). Behaves like [constant 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. Framerate is limited by the monitor refresh rate (notwithstanding [member Engine.max_fps]). Behaves like [constant VSYNC_ENABLED] when using the Compatibility rendering method. Displays the most recent image in the queue on vertical blanking intervals, while rendering to the other images (no tearing is visible). Framerate is unlimited (notwithstanding [member Engine.max_fps]). Although not guaranteed, the images can be rendered as fast as possible, which may reduce input lag (also called "Fast" V-Sync mode). [constant VSYNC_MAILBOX] works best when at least twice as many frames as the display refresh rate are rendered. Behaves like [constant VSYNC_ENABLED] when using the Compatibility rendering method.
