Description _ tboudreau 2010-01-13 21:43:14 UTC

We should probably hide the "background" property on JFrames/JDialogs/JWindows the same way we hide properties like "toolkit" - on any of these, what you actually want is getContentPane().setBackground().

Can not change JFrame background color at design time

This is still a duplicate of issue 36710.

If you want to set the background color of the content pane of the JFrame, you must do it in the code via getContentPane().setBackground(...).

If you want to see the background in the GUI builder then e.g. add JPanel over the whole JFrame area in the designer (possibly use BorderLayout). Or design a JPanel separately and add it to a JFrame programmatically.

I.e. set the background on a JPanel that spans the whole JFrame content area.
