Stop the Creation of a View in IViewPart#createPartControl [message #441095]

Hello everyone. I have a problem with one of my views. A dialog pops up
when the view is created from the createPartControl method. The view
displays a map, and the user can decide which custom map they want to load.
If they press the cancel button the view still pops up, just with a blank
canvas. Is there any way to stop the creation of a view this late in the
lifecycle of a view? Thanks

Chris

There seems to be no way of stopping viewpart creation if view is opened using Window > ShowView action of workbench (Everything is late here). If at all any hack could be done, that would be against the API contracts.

But if viewpart could be created by application specific action, then whatever you want you can do early on. (But may be your usecase is not like that).

Thanks

Thanks for the response. I wasn't very hopeful in getting a response that i
wanted. I figured it was too late to close a view at that point without a
hack. Thanks again

Did you try scheduling a background job, which closes the view after
waiting 0.5 seconds or so? Another option is to continue the view
creation and putting a nice text label on it that tells the user to
close and reopen the view.

Anyway, from a usability point of you should try to re-design you view,
allowing to reopen the selection dialog from within the view tool bar to
repopulate it at any time. Note that a view only gets disposed an
recreated if it is closed in ALL perspectives.

Cu, Gunnar

Hello,
The only thing that is holding me back is that in the design we didnt want
to have a default "map" that would be loaded every time the view was
created. But it looks like this might be the only choice. And there is a
menu option to load a new map. So maybe a default map load is the best way
to go. Thanks everyone for your help.
