Hello, I have a problem when the scrollpane are too long. Just look at the image

How to make the image stay the same while I scroll down the panel ?

This is part of my code

And this is how I set the background image


I also have tried on my own, two trial.
First, I search wheter I can set the background on the frame instead, and the result is none. It is not possible

Second I tried to make a new panel, and put this as my background panel, and add the scrollpane to this panel (before, I put the scrollpane on the frame). But, the problem comes from the unmoving scrollpane/ Failed
I tried another alternative as to set the layout of this panel as border layout, the scrollpane is working fine, but the background cannot be seen even though I setOpaque(false) this panel.

Please help me. Thank You.

How are you adding that image to the scroll pane? How are you adding that scroll pane to the frame? Where do all the Japanese→English translations come from?

It is a long code and I do not think that other part of code will affect the solution in any way. In short I use combination of ArrayList<TextArea> for those japanese english translation and ArrayList<JButton> for those delete button. and adding all of them in sequence to the gridpanel.

You need to paint the image on the viewport of the scroll pane and make your panel transparent:
