Note: Windows are moved/resized based on their apparent position/dimensions rather than actual values.
WinPos_Get(hWnd)
Returns X,Y,W,H as an Object. This function is a an alternative to WinGetPos command.
- Example:
The following example shows the apparent position as well as the adjustments applied to derive X,Y,W,HCode: Select all
Gui +hWndhWnd Gui, Show, x0 y0 w200 h200 G := WinPos_Get(hWnd) Msgbox % G.X . A_Tab . G.Y . A_Tab . G.W . A_Tab . G.H . "`n" . G.XA . A_Tab . G.YA . A_Tab . G.WA . A_Tab . G.HA
WinPos_Set(hWnd, X, Y, W, H)
Moves/resizes a window and returns a true when successful. This function is an alternative to WinMove command.
You may not use X,Y,W,H returned by WinGetPos command.. Use WinPos_Get() instead.
- Example:
Code: Select all
Run, Notepad.exe WinWait ahk_class Notepad hWnd := WinExist() WinPos_Set(hWnd, 0, 0, 400, 400)
WinPos_OffEdge(hWnd, XOffset, YOffset, MonitorNumber)
Moves a window relative to an edge of a monitor. Returns true when successful.
If XOffset or YOffset is zero or greater, they are an offset from left,top edges.
If XOffset or YOffset is a negative number, they are an offset from bottom, right edges.
The windows will be centered on the respective axis if XOffset or YOffset or both are omitted.
If MonitorNumber is omitted, window move will default to Primary monitor.
- XOffset,YOffset for common edges
- Example:
WinPos_OffEdge() is API driven and will move a hidden window. One problem in Windows 10 is that DWM does not compose hidden windows.
It applies effects only when window is shown. Therefore, a window has to be visible for correct calculation.
The following example demonstrates showing a window offscreen and then move it. You may refer What is the maximum desktop resolution in Windows.Code: Select all
#NoEnv #SingleInstance, Force Gui +hwndhGui Gui, Show, x64000 y64000 w200 h200 WinPos_OffEdge(hGui, -1, -1) ; move window to right-bottom corner of primary monitor Return
