Eclipse 中的透视切换窗格消失

Question

The little Perspective Switching Pane is gone from the upper right hand corner of my Eclipse Window after an Eclipse crash. I downloaded the newest version and tried opening that (with my same workspace), but the buttons are still gone.

Here is a screenshot:

And zoomed in:

Any ideas?

I can still switch perspectives by selecting Window->Open Perspective

Thanks

Answer 1

It's not just the perspective switcher that's missing, it looks to me; there's no tool bars, ether.

You might check Window..Preferences..General..Appearance, and fiddle around with the Perspective Switcher control, see if that makes a difference.

You could also use Window..Customize Perspective and see if anything looks interesting there.

Answer 2

Try Window > Reset Perspective...

Answer 3

Related. I had my switching pane disabled (I think I moved it by mistake and I could not see it anywhere) although the tool bar was there. The only way I could get it back was to disable themes on Windows -> Preference -> General -> Appearance -> Enable theming.

Answer 4

Using 2022-06 (4.24.0), mine also disappeared.

I was only able to get the buttons back by

• right-clicking and "unlock the toolbar"
• Window->perspective->open perspective->other

After opening each of my favorite perspectives, the buttons "stuck to the bar" then I locked it again when I was done.

Another possibility is to delete the workbench.xml from [workspace]\.metadata\.plugins\org.eclipse.ui.workbench , which forces the platform to reset the workbench-layout.
