The problem with this is not that it cannot be deleted. The problem is that the method for its removal is so obtuse and obscure that you have to re-learn the technique when it happens to you. It happened to me. Again. I forgot what I learned the last time. I googled and got to https://forums.opensuse.org/showthread.php/514072-Deleting-the-evil-sticky-notes-from-toolbar
Except, of course, KDE has improved its interface so that is now obsolete. By “improving” I do not really mean that they made it obvious. Just different. The three horizontal bars does not lead me to the sticky note widget. I guess they like making sticky notes really, really sticky.
You put your cursor on the widget and hold down the left mouse button for a long time and a little bar appears on the side of the widget which if you click on the red X will get rid of it.
By “long time” the author does mean “way longer than you would expect”.
Stupid question addressed to the ether: why isn’t it associated with a right click?
I’ve never used the sticky note widget, so I had to search for it and and add it first. I’m using openSUSE 42.3 (with KDE Plasma 5.87). Removing it again was a simple process - click on the widget menu button so the slide out menu exposed and with cursor over the sticky widget, right-click to remove it or via the little red ‘X’ that appears. Described here as well…
I selected some text with mouse. Then I middle-click on my disktop (outside of any window). And that creates a sticky note with that text. It happens using “Desktop containment” layout. It happens use “Folder view” layout.
And it is something that you can easily do by accident.
Apparently, I need to learn how to lock my widgets, whatever that means. I got into the mess by middle clicking my desktop and not realizing it and not knowing how to deal with it. Thank you for the lock widgets hint.
