Is it possible to put a couple of GLCanvases inside a JSplitPane?
GLCanvas is a heavy weight so chances are it won’t play nice with a JSplitPane. Use GLJPanel - its slow but for an editor it should be adequate.
Thats not really an option - speed it the reason for wanting to use GLCanvas in the first place
I’m currently using a GCCanvas in a JSplitPane
Seems to work fine
I’m quite the newbie so I may be doing something I shouldn’t, but it works for me
I can send some code snippets if you want
check this out

hope it works from outside my house

BTW, ignore the stuff in the left pane, it’s not functional
Are you putting them in directly or using a wrapper of some kind?
Originally, my app had nothing to do with jogl. It was a splitpane with a tree on the left, and when you clicked on any leaf in the tree it displayed the appropriate panel on the right (other leaves would show tables with data from database if db machine was online) . when I started playing with jogl I just created a new panel to play with. Here’s the code for my jogl panel. I cut out a lot of the unrelevent stuf, it was to long to post, I hope it’s not unreadably. I still have a really wierd problem with loading textures, with it made into a webstart app it loads the textures correctly on some machines and not on others. The cubes should have a stained glass image mapped onto them, did you see that or just mono-color??

I left out the part for how I build the scene but it shows how I created the GLCanvas
"The cubes should have a stained glass image mapped onto them, did you see that or just mono-color?? "
Sorry, it didn’t run for me at all when I tried it :’(
No exception text - it seemed to fail before even starting up the JVM (probably a network issue?)
Placing the canvas in a JPanel solved most of my splitpane issues
