QTextEdit not deleted when implemented as list

[Santosh Reddy]

Use takeAt() instead of at()

//int cnt = list.count();
//for(int i = 0; i < cnt; i++)
//	delete list.takeAt(i);
//list.clear();
 
while(list.count())
	delete list.takeAt(0);

//int cnt = list.count();
//for(int i = 0; i < cnt; i++)
//	delete list.takeAt(i);
//list.clear();

while(list.count())
	delete list.takeAt(0);

To copy to clipboard, switch view to plain text mode
