WinWait

Waits until the specified window exists.

WinWait WinTitle, WinText, Seconds, ExcludeTitle, ExcludeText

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

Parameters

WinTitle

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

WinTitle may be blank only when WinText, ExcludeTitle, or ExcludeText is present.

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.

Seconds

How many seconds to wait before timing out and setting ErrorLevel to 1. Leave blank to wait indefinitely. Specifying 0 is the same as specifying 0.5.

ExcludeTitle

Windows whose titles include this value will not be considered.

ExcludeText

Windows whose text include this value will not be considered.

ErrorLevel

ErrorLevel is set to 1 if the command timed out or 0 otherwise.

Remarks

If a matching window comes into existence, the command will not wait for Seconds to expire. Instead, it will immediately set ErrorLevel to 0, update the Last Found Window, and the script will continue executing.

While the command is in a waiting state, new threads can be launched via hotkey, custom menu item, or timer.

If another thread changes the contents of any variable(s) that were used for this command's parameters, the command will not see the change -- it will continue to use the title and text that were originally present in the variables when the command first started waiting.

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