K so i made a little application in Java to grab the ingame coordinates of where you clicked on a runescape world map. To do this i just made a subclass of JPanel, and added a mouselistener to listen for when i click on it, and overrode the paintComponent method to draw my currentX and curretY & the map image. I then added this to a JScrollPane, so i can scroll around the map. My problem is when i add a mouselistener to the subclass of JPanel, when i click, i get a white box from the top left of the panel, to the point i clicked. This only happens when i add a mouse listener. I really have no idea why this is happening. Is this JScrollPane and my JPanel class conflicting? Or is it just some bug with JPanel, or could it be that i made the GUI in Netbeans. Also this bug only happens when i don't run the file in Netbeans. If i run the program with netbeans and i click i don't get a white box, but if i were to run it in Eclipse i would get the white box. Oh and i tried google :cool:.

Looks more like a rendering problem then anything. Any exceptions being thrown?

Nope, also, when I drag my mouse(with a mousemotionlistener added) and repaint, the white box will dissapear.

Maybe something with your repaint method.

Idk, it's only when I add a mouselistener to the panel and click, like I don't even have to call repaint(), it just draws the white box.

I can later on because I'm not home right now, I think I can just add a mouselistener to the jscrollpane it's in then call the methods in the JPanel class, I hope that fixes it lol.

You may want to say what you figured out before I close it. It may benefit others.

Oh ok,
Well my problem was on mousePressed I was setting a flag to true so it would draw a box from the point I clicked to the point I where I would release the mouse, then set the x and y for the box to 0. My problem was when u just click your mouse i forgot that mousePressed and mouseReleased still get called, and since I hadnt moved my mouse the x and y for the box was at 0. And when I draw the box I draw from the x and y to the Mouses current x and y, so it would draw a big box to my x and y when I clicked because mouseReleased and mousePressed were still getting called. To fix it I just did some checks to make sure the x and y for the box weren't 0. It was a silly mistake lol. Yeah I guess that's hard to understand lol. I'll be releasing this soon anyway if anyones that interested in the problem.
