Hi,
I have a utility which exports Table/Tree content to HTML with all its labels and icons.
Since this involves accessing GUI elements,this export hangs the GUI.
I tryed to put the whole process in a UIJOB,syncexec etc
but the progress dialog was not able to show up.
Hence in the loop where each Table/Tree item is processed i added the code
Display.getcurrent().readAndDispatch();
this solved the problem and the progress monitor dialog got updated properly.
Is this correct?
Are there any side effects???
Thanks in advance for your replys.

Any SWT Application or RCP application has this loop
while (!shell.isDisposed())
{
if (!display.readAndDispatch()) display.sleep();
}
display.dispose();
Since we are doing a long loop on display thread its not able to read and dispatch ,hence what if we do it in between loops for such situations...
For that matter a UIJob does not make sence appart from running the task in ui thread it servers no pupose of a job(progress,manage etc)
Also what if there is setuation where you have to do a long job on ui,should we leave the UI blank and un responsive???
