uevent_onidle
uevent::onidle(n) User events uevent::onidle(n)
__________________________________________________________________________________________________________________________________________________
NAME
uevent::onidle - Request merging and deferal to idle time
SYNOPSIS
package require Tcl 8.4
package require uevent::onidle ?0.1?
package require logger
::uevent::onidle objectName commandprefix
objectName request
_________________________________________________________________
DESCRIPTION
This package provides objects which can merge multiple requestes for an action and execute the action the moment the system (event loop)
becomes idle. The action to be run is configured during object construction.
API
The package exports a class, uevent::onidle, as specified below.
::uevent::onidle objectName commandprefix
The command creates a new onidle object with an associated global Tcl command whose name is objectName. This command may be used to
invoke various operations on the object.
The commandprefix is the action to perform when the event loop is idle and the user asked for it using the method request (See
below).
The object commands created by the class commands above have the form:
objectName request
This method requests the execution of the command prefix specified during the construction of objectName the next time the event
loop is idle. Multiple requests are merged and cause only one execution of the command prefix.
EXAMPLES
Examples of this type of deferal are buried in the (C-level) implementations all the Tk widgets, defering geometry calculations and window
redraw activity in this manner.
