I need to override some method for JTable. How can I insert extended JTable then in my code? If inserting some code in jformdesigner generated code it is overwritten later. How to be in this situation? Thanks
First, add the element as a regular JTable. Then, select it, and find the class property. Press the little ...-button, and IntelliJ should start scanning your project files for candidates (I think it looks for anything that inherits a Swing-class.) I remember having some difficulties finding my class when I did this a couple of years ago, as far as I can remember I think it needed a compiled version of the class available. I see now that it scans the classpath of the module, so some maven dependencies plus target\classes-folders in my case. So make sure it is on the classpath and that you have built your project, and it should be available.
