# Position

The following flags have an effect only when the "run in window" option is selected (with the WINDOWIZE flag).

Hide desktop background | HIDEDESKTOP | Starts the windowized program together with four black borderless windows that surround it entirely, eliminating distracting background windows and providing a more focused gaming experience. The whole idea was borrowed from "Mr. Hide."
Keep aspect ratio | KEEPASPECTRATIO | When the window is resized, the aspect ratio set by the window initial size is preserved (by default the 4:3 aspect ratio such as 800x600). Selecting a fake fullscreen mode calculates the aspect ratio according to the window's initial aspect ratio. This way, you can have fake fullscreen modes with ratios other than 4:3 - for example, set a width of 16 and a height of 9 to fill a 16:9 widescreen monitor.
Window initial position & size |  | Four values for the initial X, Y coordinates of the upperleft window corner and the window width and height. All values are referred to the window client area rather than the outside border. The values are used depending on the Position selection: for "X, Y" coordinates they are all used, for "Desktop center" DxWnd automatically centers the position and uses only the height and width, and in the remaining fake-fullscreen modes the height and width are used only as a reference for the desired aspect ratio when "Keep aspect ratio" (the KEEPASPECTRATIO flag) is set (if it has not been set, the height and width are ignored).
Monitor |  | For almost all window position modes (except the "X,Y coordinates" mode), multi-screen configurations require you to specify which monitor the configuration refers to. For instance, if you select "centered," you probably want it centered on a specific monitor rather than in the entire extended desktop. The drop-down selector has a "def." ("default") option, referring to the primary monitor, and a number for each specific monitor.
Coordinate picker |  | This icon activates a mechanism to pick the new program placement coordinates (see "Window initial position & size" above) using an existing window on the desktop. Click and drag from the icon to the desired window to automatically fill in the "Window initial position & size" fields with these window coordinates. Release the mouse button while over the title bar or an empty area in the desired window, as releasing the mouse button over a widget (like a text field, button, or other object) will select coordinates for that widget rather than the entire window.
Position |  | A selection of 4 possible cases: X, Y coordinates: the window is placed at the chosen coordinates Desktop center: the window is centered on the screen, and only the width and height fields are used. Desktop work area: the window occupies the whole screen but the bottom taskbar. Desktop: the window occupies the whole screen, as if it was fullscreen (a.k.a. Fake-fullscreen mode) Note that the first two modes are windowed modes, while the last two modes can be considered fake fullscreen modes. This is because the behavior of the KEEPASPECTRATIO flag changes along with this classification.
