Hi, I have a J3D application which uses Swing components in a control panel. The Swing components are on a number of JPanels; these are contained in a JPanel with a CardLayout so enabling the user to switch between the panels. The individual panels generally use GridBagLayouts and, typically, contain only around half a dozen JTextField and JButtons.
The first time I switch to one of the control panels, it seems to take an awfully long time to paint the Swing components on the screen. If I subsequently switch back to the same panel, the paint is instantaneous. Likewise, if I do not add the Canvas3D, the Swing panels paint immediately.
Therefore, I can only conclude that there is some conflict between painting the Swing panels and Java 3D.
I've read on the J3D.org FAQ that deadlocks can occur if the Swing manipulation occurs on a non-event thread, but the switching between my panels happens following button presses.
I would welcome comments, observations and, in particular, suggestions on improving the performance.
Many thanks, -Paul
