widgetserver.busy - Function

	Package	display
	Module	widgets
	Tool	widgetserver

Set the busy cursor and optionally disable a frame

Synopsis
busy(busyframe, disable, busycursor)

Arguments

busyframe		The frame which will appear busy
		Allowed:	Frame
disable		Should a disable event be sent to this frame?
		Allowed:	T or F
		Default:	T
busycursor		The new cursor
		Allowed:	String
		Default:	`watch'

Returns
T

Description
This function changes the cursor of busyframe to the busycursor, which defaults to ``watch'', to indicate that that frame is busy. If disable is T, then a disable event is also sent to that frame, disabling all widgets within busyframe. When disable is T it must be matched either by a call to notbusy with enable being T or an enable event must be explicitly sent to that frame.

Example

- f := dws.frame()
- # some additional widgetserver calls to build the contents of f
- # to set the busy cursor in f and disable the widgets in f
- dws.busy(f)
- # to set the normal cursor in f and enable its widgets
- dws.notbusy(f)
