In qt programming, it will show you the run window, but one time my hand is out of control, the display window x off, after the run, the window will not appear, the people know what is going on?
2. There is a problem, the window that displays after the run, after I adjust the size, the current window size of memory, the next open, or the last time after the adjustment size of this set is automatically? Where was modified?
Question 1 and question 2 is a reason?
