NetBeans (Java Swing): setting the window size

It really drives me crazy When I set the appropriate size for my window in design mode, it just ignores this size and uses something else at compile and run time Even if it's hard for me to set minimumsize and preferredSize, it just ignores this... Why? How do I set my own size?

Solution

Even if you set the size using minimumsize and preferredSize, you may forget to call window Pack(), where swing will resize the component (and all its subcomponents) according to the set size

After setting all the preferred sizes, you can call it in the window (or anything in the build window).

Alternatively, you can use component Setsize() method, but it can use comes with some caveats
