Allow Tcl events to be serviced or not

This function controls or reports on the Tcl service mode, i.e., whether Tcl will respond to events.

Keywords
misc
Usage
tclServiceMode(on = NULL)
Arguments
on

(logical) Whether event servicing is turned on.

Details

If called with on == NULL (the default), no change is made.

Note that this blocks all Tcl/Tk activity, including for widgets from other packages. It may be better to manage mapping of windows individually.

Value

The value of the Tcl service mode before the call.
