Created attachment 171687 [details] See the empty space at the right SUMMARY Task managers widget fill the same horizontal space in the panel in multi row mode as if it were set in one row. It' s only noticeable when panel width is set to adjust to content, because when the panel is set to fill all horizontal space is normal for the task manager to leave empty spaces, but it should not be the case when panel is adjusting to content (like a dock) STEPS TO REPRODUCE 1. Force the panel to show windows always on two rows or more 2. Set the panel width to adjust to content 3. Open some programs OBSERVED RESULT The widget is occupying the same horizontal space in two rows or more than in one row, which creates a big empty space at the right EXPECTED RESULT The widget fills only the exact horizontal space needed to contain the buttons of the opened windows SOFTWARE/OS VERSIONS Linux/KDE Plasma: Feedora 40 (available in About System) KDE Plasma Version: 6.1.2 KDE Frameworks Version: 6.3.0 Qt Version: 6.7.2
how is the taskmanager setting? How many rows? is checked "when panel is low on space and thick enough" or "Always when panel is thick enough" ? currently i can't reproduce the issue with either of those
(In reply to Marco Martin from comment #1) > how is the taskmanager setting? > How many rows? > is checked "when panel is low on space and thick enough" or "Always when > panel is thick enough" ? > > currently i can't reproduce the issue with either of those - In Appearance all the options are ticked. The one that says "Fill free space" seemed suspicious to me and I try disabling it but nothing changes. - I normally use 2 rows, but I tried 3 and it happens the same. Also in both cases the widget uses the same horizontal space that it would use if set in a single row. -"Always when panel is thick enough" Since you couldn't reproduce it I also checked with the breeze theme and restarting the plasma session to be sure it's not due a theming issue, but the bug happens too with breeze. It's important to set the panel width to "fit content", since you wouldn't notice weird empty spaces in a panel that uses all horizontal space or with fixed width, as those are going to have empty spaces anyway. I'm not sure this was made clear in the first message because I have the system localization set in spanish.
I can reproduce this issue with a 46px "fit content" panel and an icons-only task manager set to show 2 rows with the "Always when panel is thick enough" setting. However I'm not sure it's actually an issue. As far as I can tell, this behavior is intentional with an icons-only task manager with that combination of settings. Are you saying that you'd prefer if the tasks filled up the top row first, before moving onto the bottom row? If so, this is the purpose of the "When panel is low on space and thick enough" setting, which implements that UX.

It's clearly not intentional since this bug wasn´t present in any Plasma versions prior to 6.1 (All the Plasma 5 branch until 6.0) Also the space occupied by the task manager growing by the same size it would grow if set in single row clearly indicates this behaviour isn´t intentional. If the task manager would work properly, the widget should grow the exact same horizontal size needed to contain the icons, and it wouldn't contain any empty space at the right > Are you saying that you'd prefer if the tasks filled up the top row first, > before moving onto the bottom row? The task should fill the widget the same as now. It's just that the widget is creating an empty space at the right that it's not needed, didn't happen before Plasma 6.1 and makes the panel size grow too fast when set to "fit content" Just to be clear, The task manager widget when the panel is set to fit content shouldn't leave any empty space at the right, and it should adapt it's size to the horizontal size needed to contain the task, which depends of the number of rows. But in fact, this is what the widget is actually trying to do, before and now. The actual bug is the widget growing always and regardless of the number of rows, as if it would grow if set in a single row: one space for one task. As it's not considering the number of rows, the result is the widget leaving empty space at the right which is not going to be used. I'm going to upload an screenshot taken on Plasma 6.0 so you can see how it looks when it's working =P
Created attachment 171803 [details] The widget properly working on Plasma 6.0.3
It'd like to clarify too that this bug happens in both the task manager and the icon only task manager
Ahh, I get it now. Can reproduce. Basically the issue is that the Task Manager widgets take up extra space in forced multi row/column mode, even when on a "fit content" panel, and even with the widget's own "Fill free space on panel" setting disabled.

Pushed by iasensio into branch 'master'. applets/taskmanager: Fix applet's layout size with multiple rows The property `Layout.maximumWidth` of the `taskList` didn't take into account the number of rows. This was compensated later when calcualting its actual width, but not for the applet's preferred size, resulting in extra demanded space. To fix it, move the influence of the rows directly into the property. This was only noticeable with the settings `forceStripes==true`, and `fill==false` because in any other combination, either the space is wanted, or the tasks fills the available space before creating a new row. Due to symmetry, the same is done on vertical panels for 'Layout.maximumHeight` and the number of columns.
