Hello, I have noticed a strange behaviour. I do not use the group windows option in my taskbar. However, when I start some software and then open additional windows from this software, they do not appear as a new window but only the first task manager element remains. E.g. when I open digikam I get a new window "digikam" in the task manager. Then I open the import dialog. Normally a second window in the taskbar should appear. But It does not. Instead the "digikam" window now represent both windows. When hiding it, both get hided and so on. A second example is Rosegarden. There I have the main window. When I open the Track editor a new window should appear, but same thing as described above happens. This is very annoying and I cannot figure out what is going wrong. The titles of the windows are not the same. Would be great, when this could be fixed. Reproducible: Always Steps to Reproduce: 1. Open e.g. digikam 2. in digikam, open import dialog Actual Results: only one digikam window is in the taskbar Expected Results: For each window a separate window should be seen in the taskbar
This is normal behavior that's been around for about 20-30 years. It's called modal dialog windows, see e.g. https://en.wikipedia.org/wiki/Modal_window If an application really wants to, they can make additional windows (a) not modal, (b) not give them a transient parent and (c) give them a suitable top-level window type. They will then show in the Task Manager. But modal, transient dialog-type windows by default do not show, and that's correct behavior.
But this behaviour was not presented in the mentioned software in KDE4. I cannot imagine, that this was an intended decision from both software developer teams at the same time. Anyway this windows are meant to be opened at the same time (at least for rosegarden, where this is a essential feature to open the track editor beside the main window).
I'll install Rosegarden and take a look and report back, but it's likely to be an application bug then.
Where do I find this Track Editor?
The mentioned windows were not modal ones in KDE4 where I was able e.g. to open the import dialog in digikam then start the download and return to the main window while the import dialog remains open. This cannot be done with modal windows as described in the article you have linked previously. Also now, with plasma 5, I still can switch between the different windows as I want except that only one taskbar window is shown for both windows...
(In reply to Eike Hein from comment #4) > Where do I find this Track Editor? Start a new rosegarden session, then create a track with the pencil tool in the main window (draw a yellow coloured strip. Then double -click on it. This will open the score editor (or track editor as I have called it before).
Created attachment 101178 [details] Rosegarden Task Manager I get three Task Manager entries ... it's 5.8 code, but it hasn't changed since 5.7.5 for this.

Ok, but at least I am sure now, that it is not the apriori behaviour of the software. Can you imagine from where this behaviour can come?
I wrote the code and I really can't, no, unless the application set the window properties differently, or there's a bug I don't know about yet. I'd say we close the ticket for now, and if it happens again to you you reopen it, and we try to find the pattern?
Maybe we can wait for some other people to have a look at it, because it still happens to me permanently.
Can't reproduce. Are you still seeing this in Plasma 5.11?
