The Window device allows to show a window in which visuals will be rendered.

Its device tree contains the following parameters:

Window properties

• /screen: on which screen the window must be shown.
• /position: absolute position of the window on the user’s viewport.
• /size: window size in pixels.
• /rendersize: the resolution at which rendering is done. If it is [0, 0] then the renderer is rescaled to follow the window resolution.
• /fullscreen: show as fullscreen. Double-clicking on the window will also trigger this.

Mouse input

• /cursor/scaled: mouse cursor position in the window scaled to [0;1] bounds.
• /cursor/absolute: mouse cursor position in the window in pixels.

Tablet input

• /tablet/scaled: tablet pen position in the window scaled to [0;1] bounds.
• /tablet/absolute: tablet pen position in the window in pixels.
• /tablet/z: tablet pen height.
• /tablet/pressure: tablet pen pressure.
• /tablet/rotation: tablet pen rotation.
• /tablet/tangential: tablet pen tangential pressure.
• /tablet/tilt_x and /tablet/tilt_y: tablet pen tilt.

The values are extracted directly from Qt’s QTabletEvent.

Keyboard input

• /key/code: low-level key code corresponding to the current user input. One per keystroke.
• /key/text: high-level combined result of the user’s keystrokes. For instance, a user pressing “Shift + G” will yield a capital “G” text here.
