Hi Curtis, Yippee, someone gets what I'm trying to do! Student labs are closed over the weekend, will try out what you said on Monday morning. >I'm not certain whether your goal is to have four displays (an "original", >an "x2", an "x3" and an "x4"), or just one or two displays that get updated >when the buttons are pressed. I'm after the latter; find attached a screen shot of a sketch of the program. I'm not sure if one is allowed to sending .gifs to a mailing list, I've made it as small as possible. Apologies in advance... >Adding components to a window that already onscreen can be tricky, and >should be avoided if possible. Tell me about it... Cheers! Chi-chi PS I actually meant I'd moved makeDisplay() *out* of the twist() methods in my earlier reply to Bill. -----Original Message----- From: Curtis Rueden [mailto:curtis@xxxxxxxxxxxxx] Sent: 17 May 2003 02:25 To: Chi-chi Ekweozor Subject: Re: Repainting images in JyVisAD Hi Chi-chi, Your problem is due to the unusual layout you're attempting to use for your Swing components. You can "fix" the problem by adding the following two lines as the last two lines of your twist1 subroutine: frame.validate() frame.repaint() However, you may notice that your old, unstretched display is being crunched into the five-pixel gap between the (new) left and right displays. Certainly that is not the desired behavior. I suggest not creating new displays on button click. Instead, create all desired displays, add them to the GUI, all at the beginning of the program. When the user clicks a button, update the relevant displays as desired. I'm not certain whether your goal is to have four displays (an "original", an "x2", an "x3" and an "x4"), or just one or two displays that get updated when the buttons are pressed. But either one should be possible without needing to add displays later. Adding components to a window that already onscreen can be tricky, and should be avoided if possible. Good luck, -Curtis
