uevent::onidle - Request merging and deferal to idle time
Contents
Api
The package exports a class, uevent::onidle, as specified below.
::uevent::onidleobjectNamecommandprefix
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:
objectNamerequest
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.
