TestCase that fails.
Here is a small test case showing the problem.
- I see a Widget is Disposed exception when closing the example after opening/closing 1+ browsers - the exception I see has a different trace than the one in comment 0, but is still Widget is Disposed - the presence/absence of Sleak is not relevant to the problem I have a similar problem as described below. The added complication of dual bridging is probably not relevant. It does however appear that removal of the ole container from a parent container is the cause of the problem. Problems with SWT AWT Bridge I am trying to embed a windows mediaplayer object in a java application, using the SWT-AWT Bridge, within a swing application which is wrapped by an SWT Frame. This is because the application is also used as an applet. The system uses JAVA 1,5 compatability, a requirement for use on a MAC. The media player wrapper is held in a panel which due to view requirements is moved between parent containers. Note the embedded SWT for the media player uses the dispatch loop of the applications frame. A minor problem is getting tyh media player to size to its containing panel, but a resize of the application achieves this. The major problem is that when the containing panel is removed from a parent container, the mutimedia object is disposed of. Creating a new instance is carried out, but now a resize of the application causes an exception listed beow :- Exception in thread "AWT-EventQueue-0" org.eclipse.swt.SWTException: Failed to execute

to be the display object of the shell for the media player. However program tracing showd that it is NOT disposed either side of the create shell invocation. The media player stays running, as does the embedded swing stuff, but the SWT frame ceases to respond, can't be resized, or closed. Note the mediaplayer can be disposed of and recreated to play media without problems other than initial size, and the application resized without problems in one of the views. Also I have tried running a dispose of the media player via synExec() before its containing panel is removed from its parent, but this does not prevent the exceptions. The exception allows occurs after the containing panel has had the mediaplayer object created, been removed from its containing panel, reinserted into the panel and a new mediaplayer object creted, and the application resized. It does not matter whether or not the application is resized for the first created media player. Also media players can be disposed of, and new ones created and resized without problems so long as the containing panel remains in its parent. Once a media player has been created, disposing of it before the containing panel is removed from its container does not affect the problem. Removal of the containing panel from its parent causes it to be disposed if not previously disposed of. A new media player can be created in the panel, and starts playing the media , its is when the application resizes that the failure occurs. This appears to be the same as bug 142582. This may help :-) Andrew Just to clarify my previous posting, the problem occurs for a newly created olecontrol after the container panel has had a control created for it, regardless of whether this is disposed of before it is removed from its parent. Removal of the container panel from its parent triggers the bug. This also the disposal of the control container if it left alone before this event. I would not expect this as this can be part of user interface re-organization, with the container panel replacing an split pane control for example, where i would expect the control be be in an unchanged state. Also, where a card layout manager is used to switch displayed panels, the control container can be switched in and out without causing the bug. I hope this points someone in the right direction, Andrew. Your bug has been moved to triage, visit http://www.eclipse.org/swt/triage.php for more info. This is a one-off bulk update. (The last one in the triage migration). Moving bugs from swt-triaged@eclipse to platform-swt-inbox@eclipse.org and adding "triaged" keyword as per new triage process: https://wiki.eclipse.org/SWT/Devel/Triage See Bug 518478 for details. Tag for notification/mail filters: @TriageBulkUpdate This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're closing this bug. If you have further information on the current state of the bug, please add it and reopen this bug. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. -- The automated Eclipse Genie. |
