Hi everyone, I made a swing application in java, but the problem is that I can achieve a transparent frame in java.
I want to create a user interface design, like in an attached image, but the problem is that the frames are not transparent, so it shows the default color if there are no components at this level.
As on the right side, I want to show this frame transparent in the upper free and lower free parts,
I use AWTUtilities, but this does not work for me.
how can i do this, plz answer,
also give me a tip to drag the window along the title bar, in an undeclared window
early
