问题 Pull out a div from the left? Easy as pie. Pull it out from the right? Not so much. I am looking for a div to be hidden offscreen but connected to a small tag on screen. When the user clicks the tag, out slides the whole div. This is pretty basic from the left using jQuery and CSS. From the right though, a user can just scroll over to see the "hidden" div!

问题 I want to paint the contents of a JFrame onto another frame. Currently, I only get it to work if the JFrame is visible. Is there a way to paint a hidden JFrame? Additional info: In my project I need to be able to rotate and scale windows. I do not want to write my own window-api, so I thought I might be able to just paint JFrames or similar container classes in a rotated way (which the Graphics2D-API supports perfectly well). It would be awesome to be able to use standard JFrames for that,
