Hi,
	I tried to implement a function with QPushButton , that will stop a
task that is running.

	e.g A function used to search for specify strings in all of the files
inside a directory , if the directory has a long scope , user may want
to stop it.

	So far what i did is make the QPushButton checkable , and during the
loop in the directory , everytime before i search in a file , i will
check if the Button is `checked'.
	If it's checked , jump out of the loop immediately , and stop searching.


	The problem is , during the search function , user interface will stop
answering me , so i won't be able to click on the button , in that case
, i can't stop the search function.

	Does anyone has any ideas ?

	Thanks in advance !
