How to display a MessageDialog on startup ? [message #107735]

Hi,

I am trying to display a Hello World Dialog Box (something like
tip-of-the-day) on eclipse startup...how can I do that ?

I have attempted to write a plugin implementing IStartup, when I run it in
Workbench I can find it in Preferences > Workbench > Startup. But if I
write
MessageDialog.openInformation( ..) function inside the interface
implemented method earlyStartup()..it gives either NullPointerException or
some Invalid Thread Access SWT related error. I think it is because of the
first argument of openInformation -> Shell (parent) I am not able to
define properly.

How can I get the Shell within earlyStartup method...am I on the right way
or something is missing ..?

Thanks in advance.

Hi:
You can do that like this:

MessageDialog.openInformation(window.getShell(),"Hello","tip-of-the-day ");
It should be in the Run method.

The docs for IStartup.earlyStartup() state that is will be called in a
background thread. If you want to do anything UI-related, you will need
to run that code on the UI thread. See Display.syncExec() and
Display.asyncExec().
