Getting window info

If there's a specific application or window misbehaving, it's useful to be able to identify it. Here are two methods to find its information.

KWin debug console

1. Open KWin debug console
2. Find the problematic window in the tree view
   • If it's not clear which one it is, try closing as many windows as possible, then use the process of elimination
   • If it's still not clear, try the other method
3. Expand the window in the tree view and note the following properties:
   • caption
   • resourceClass
   • windowType

KWin window rules

Note: Don't click apply at any point

1. Open KDE System Settings -> Window Management -> Window Rules
2. Click on Add New...
3. Click on Detect Window Properties
4. Click on the window you wish to inspect
5. Note the following properties:
   • Window class (application)
   • Window title
   • Window types (click on it to see the actual window type)
6. Click Reset (we got what we needed, we don't need to add any window rules)
