Can jet fix SWT gui bugs?

Recommended Posts

SWT can be superb if we can fix gui screen bugs. If you drag or rub other windows in front of SWT frame windows, we tend to get unpatched screen rectangles. This is especially true when we have heavy components and/or slow CPUs.

This problem may be related to the use of old APIs that is not well supported in XP or etc. Using Jet, can this problem be fixed?

Excelsior JET is just another compatible Java SE implementation, not a silver bullet. If something is broken in HotSpot VM, chances are good that it is not broken in Excelsior JET. But if there is a bug in a third-party API that manifests itself on the Sun JRE, it is unlikely to disappear on another implementation, being it Excelsior JET, Oracle JRockit, or IBM JRE.

What you can do is:

  • direct your complaints to SWT authors;
  • make the fixes yourself and contribute them back to SWT; or
  • pay someone (e.g. Excelsior) for fixing SWT

"another compatible Java SE implementation"

This is why I am interested. The use of old Windows APIs in SWT may make the problem. If jet uses own implementation with different newer Windows APIs, this might remove the problem?
