Causes fvwm to record a mouse stroke sequence and to execute the corresponding action as defined in a Stroke command. The cursor is modified to the STROKE context of the CursorStyle command during recording. When the stroke is finished StrokeFunc looks for a stroke binding of the form

Stroke sequence 0 Context Modifiers action

and executes the corresponding action (Note the 0). Normal use of this function is via a Mouse or Key command. Examples:

Mouse 3 A M StrokeFunc
Key x R N StrokeFunc

If you press mouse button 3 and Alt anywhere (respectively, press the key x when the cursor is on the root window), then fvwm records the mouse motions until the mouse button 3 (respectively, the x key) is released and then check if the recorded sequence corresponds to a stroke binding of the form

"Stroke sequence 0 A M action"
"Stroke sequence 0 R N action"

Note that the Context and Modifiers are taken at the beginning of the execution of the StrokeFunc command (so you can release the modifiers before the end of the stroke recording in the case of a mouse binding and if you used, say, a title-bar context the mouse motion can go through an application window). The keys Escape and Delete allow you to abort the command.

The StrokeFunc command has five options: NotStayPressed, EchoSequence, DrawMotion, FeedBack and StrokeWidth. These options are disabled by default. EchoSequence causes fvwm to Echo the recorded stroke sequence. DrawMotion causes fvwm to draw the mouse motion on the screen. FeedBack causes fvwm to display during a fraction of second the cursor of the WAIT context of the CursorStyle command if the recorded stroke sequence corresponds to a stroke binding. StrokeWidth takes an integer argument, which must be >= 0 and <= 100 and which defines the width of the line for the DrawMotion option.

NotStayPressed works only if StrokeFunc is used via a Mouse or a Key command. This option removes the need to have a button or the key pressed during the stroke, but you have to do a mouse click or press the Return or Space key to finish the mouse motion recording (these keys also work without the NotStayPressed option).

You can use the StrokeFunc "alone". In this case it works as above with the NotStayPressed option enabled. However, Modifiers, in general, may not work as expected (i.e., in this case use 'A' or 'N' as Modifiers in the stroke bindings).

Note that some computers do not support key release events. If that is the case the StrokeFunc used via a Key command works as if the NotStayPressed option is enabled.
