You can simply create your jPanel using drag and drop, as you always do and then for changing the panel's color and making it transparent or semi-transparent you can use this code: panel. setBackground(new Color(0.0f, 0.0f, 0.0f, 0.5f));
The alpha value defines the transparency of a color and can be represented by a float value in the range 0.0 - 1.0 or 0 - 255. An alpha value of 1.0 or 255 means that the color is completely opaque and an alpha value of 0 or 0.0 means that the color is completely transparent.
In general, to set the JFrame background color, just call the JFrame setBackground method, like this: jframe. setBackground(Color. RED);
I found another solution.
Set the background color of your frame to
// Set the frame background color to a transparent color
yourFrameHere.setBackground(new Color(0, 0, 0, 0));
And remember to set the opacity off of the contentpane (your JPanel or other component)
// turn off opacity of the content pane
yourContentPaneHere.setOpaque(false);
