Hi,
i can´t find any information about how to close a viewpart correctly.
In my example i create a view with one composite. When i use the
this.dispose() method i get a "Graphic is disposed" error.
My Example:
A view which logins in a server through a webservice. Is the user valid,
the view shows a table with data. Is the user not valid, a pop-up
message is shown with the error message an the view should be closed.
thnx a lot

You can try something like this:
IWorkbenchWindow[] windows =
PlatformUI.getWorkbench().getWorkbenchWindows();
for (IWorkbenchWindow window : windows) {
for (IWorkbenchPage page : window.getPages()) {
for (IViewReference ivr : page.getViewReferences()) {
if (ivr is the one you want to close...) {
page.hideView(ivr);
}
}
}
}
For the ivr test, pehaps you can use the primary and or secondary ID.

How do you create your view?
The only way to create a view is by using IWorkbenchPage#showView(...),
the only way to remove a view is by calling IWorkbenhPage@#hideView(...).
Anything else won't work.
You can extend IWorkbenchPart#dispose() if you want, and then you would
call super.dispose(), but that's the only time.

That doesn't create a view. It declares that a view is available for
use. Someone must select Windows->Show View to show the view, or it must
be configured to be on a Perspective, and then the next time that
perspective is newly opened the view will be there. Or there must be
some action that explicitly does a show view.

Yes, thats right. Someone opens the view by clicking Windows->Show View.
But my problem is that before the view opens something will be checked.
If it is false, then the view should not be opened.
So i want to close the view in the view class.

There's not an easy way to do that. Why do people want to fight Eclipse instead of working with it?
If a view is there, it should be openable. It might not have the correct context, but it shouldn't prevent it being opened. It should just show an empty area.
There's many reasons why you might want a view to be opened even if you know you can't use it. To customise a Perspective, to drag it into the right place, to resize it, and so forth.
Imagine if the Console or Errors view in Eclipse refused to open just because there weren't any messages available.
Work with Eclipse, and Eclipse gives you wings. Fight Eclipse, and you write crap plugins that no-one will want to use.

Why not just show an error message in the view if the "something"
which was checked fails?
Trying to close a view while it is in the process of opening is
bad practice.

Hi,
okay, maybe it is the wrong way.
I will let the view opened till the user close it by himself.
The advantage is that the user can still manipulate the view like
resizing and so on.
Thanks a lot for your answers :-)
