Removing the "Show all" checkbox in the Open Perspective popup.

[atwhelan]

Hello,
I am developing an Eclipse RCP application. I am trying to figure out how to remove the "Show all" checkbox from the "Open Perspective" popup. You see this when you choose Window->Open Perspective->Other.
The solution might involve Eclipse activities like discussed in the Vogella article: [eclipse-activities (https://www.eclipse.org/forums/index.php/t/155910/) but the article doesn't specifically address this.

All I was able to find with Googling was a 16 year old question in an Eclipse Forum that was never answered: https://www.eclipse.org/forums/index.php/t/155910/

Any help with this would be greatly appreciated.

You probably can't remove checkbox (unless there is some extra code in platform that is written to do exactly that), but you could "hide" all perspectives you don't like via activities, so even if users would open that dialog, they will only see "allowed" perspectives.

Hi, thanks for the quick response! I already have used activities to hide perspectives that I don't want available. And they are hidden until the user checks the "Show all" check box. If its checked, those hidden perspectives are suddenly available. If you then click on one of those perspectives that should be hidden you get a dialog that allows you enable it. That's why I just want to remove the "Show all".

It looks like org.eclipse.ui.internal.dialogs.SelectPerspectiveDialog.java is the culprit dialog. It has this needsShowAllButton method.
private boolean needsShowAllButton() { return activityViewerFilter.getHasEncounteredFilteredItem(); }
It would be nice if there was a way to configure this in a plugin to just always be false without having to override tons of code.
Does anyone know of a way to do this?
Does anyone know of a good example application where functionality like this was overriden for a plugin, like which extension point to use?

Arrgh, I see. So you can try to provide a patch that would evaluate a system property (or preference) whch would disable this checkbox.
