tclServiceMode Allow Tcl events to be serviced or not
Description
This function controls or reports on the Tcl service mode, i.e., whether Tcl will respond to events.
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.
Examples
## see demo(tkcanvas) for an example
oldmode <- tclServiceMode(FALSE)
# Do some work to create a nice picture.
# Nothing will be displayed until...
tclServiceMode(oldmode)
## another idea is to use tkwm.withdraw() ... tkwm.deiconify()
