WinMaximize

Enlarges the specified window to its maximum size.

WinMaximize WinTitle, WinText, ExcludeTitle, ExcludeText

Command  Example: WinMaximize "ahk_class AutoHotkeyGUI"
Function Example: WinMaximize("ahk_class AutoHotkeyGUI")

Parameters

WinTitle

A window title or other criteria identifying the target window. See WinTitle.

WinText

If present, this parameter must be a substring from a single text element of the target window (as revealed by the included Window Spy utility). Hidden text elements are detected if DetectHiddenText is ON.

ExcludeTitle

Windows whose titles include this value will not be considered.

ExcludeText

Windows whose text include this value will not be considered.

Remarks

Use WinRestore to unmaximize a window and WinMinimize to minimize it.

If a particular type of window does not respond correctly to WinMaximize, try using the following instead:

PostMessage, 0x112, 0xF030,,, WinTitle, WinText  ; 0x112 = WM_SYSCOMMAND, 0xF030 = SC_MAXIMIZE

This command operates only upon the topmost matching window except when WinTitle is ahk_group GroupName, in which case all windows in the group are affected.

Window titles and text are case sensitive. Hidden windows are not detected unless DetectHiddenWindows has been turned on.
