Re: [eclipse-dev] SWT Apps Crash on Carbon when launched from WebStart

[Steve Northover <Steve_Northover@xxxxxxxxxx>]

Hi Mark,

Webstart uses AWT and SWT/AWT interop
does not work at all on the Mac, even in separate windows. I assume you
have read the FAQ about SWT and Mac OS X on the SWT component page?

After some investigation I have the following issues:

2.1.2  - SWT Based applications run VERY eradicly, eventually crashing.
 
  It will work for a few seconds, and then become very un-responsive.
   
Sometimes the responsivness would come back, sometimes it wouldn't  
This would occur both when executed from eclipse or when executed from
 
a *.app package.

3M4 & 3M5 - SWT Based applications hang on startup

In all cases the app hangs when executed from a terminal

I am guessing that this is related to my event loop, so here it is:


while (!shell.isDisposed()) {
                
                 
               
if (!display.readAndDispatch())
                
                 
               
                 display.sleep();
}

Am I missing something?  The app works just fine on windows (though
I  
haven't tested on linux or solaris yet).

Any help would be greatly appreciated.
