The rationale for using a window identifier and not a QWidget, is to enable grabbing of windows that are not part of the application, window system frames, and so on. The window system identifier ( WId ) can be retrieved using the winId() function. Call devicePixelRatio() to determine if this is the case. The returned pixmap may be larger than the requested size when grabbing from a high-DPI screen. The offset and size arguments are specified in device independent pixels. If height is negative, the function copies everything to the bottom of the window. If width is negative, the function copies everything to the right border of the window. The arguments ( x, y ) specify the offset in the window, whereas ( width, height ) specify the area to be copied. grabWindow ( window ] ] ] ) ¶ Parameters :Ĭreates and returns a pixmap constructed by grabbing the contents of the given window restricted by QRect ( x, y, width, height ). ![]() geometr圜hanged ( geometry ) ¶ Parameters : This property holds the screen’s geometry in pixels.Īs an example this might return QRect (0, 0, 1280, 1024), or in a virtual desktop setting QRect (1280, 0, 1280, 1024). This is the union of the virtual siblings’ individual available geometries.ĭevicePixelRatio() devicePixelRatio(). Returns the available geometry of the virtual desktop corresponding to this screen. This property holds the available geometry of the virtual desktop to which this screen belongs. availableVirtualGeometry ( ) ¶ Return type : The available size is the size excluding window manager reserved areas such as task bars and system menus. This property holds the screen’s available size in pixels. availableGeometr圜hanged ( geometry ) ¶ Parameters : This is a limitation in X11 window manager specification. In all other cases this is equal to geometry(). Note, on X11 this will return the true available geometry only on systems with one monitor and if window manager has set _NET_WORKAREA atom. The available geometry is the geometry excluding window manager reserved areas such as task bars and system menus. This property holds the screen’s available geometry in pixels. PrimaryOrientation is interpreted as the screen’s primaryOrientation(). angleBetween ( a, b ) ¶ Parameters :Ĭonvenience function to compute the angle of rotation to get from rotation a to rotation b. The logical dots per inch are sometimes user-settable in the desktop environment’s settings panel, to let the user globally control UI and font sizes in different applications. Logical dots per inch are used to convert font and user interface elements from point sizes to pixel sizes, and might be different from the physical dots per inch. ![]() ()Ī note on logical vs physical dots per inch: physical DPI is based on the actual physical pixel sizes when available, and is useful for print preview and other cases where it’s desirable to know the exact physical dimensions of screen displayed contents.
