The debugger toolbar has the nasty habit of reverting to its default location, and reappearing in views where it's supposed to be hidden Reproducible: Sometimes Steps to Reproduce: 1. Put the debugger toolbar where you want it to be, possibly hiding it in the standard code view 2. Quit the session 3. Reopen the session, possibly after having opened other sessions or with another session open that has been kept open. Actual Results: The debugger toolbar may or may not restore its previous location and visibility. Expected Results: The debugger toolbar reappears where it was told to be, and remains hidden if it was told so. Locking the toolbars has no effect whatsoever contrary to what one might expect. The "reset" appears to be triggered when anything else in the overall windowstate changed.
A bit more info on this one: apparently the debugger toolbar state is saved in more than 1 location. If it reappears against my instructions, I quit KDevelop and turn the debugger toolbar off in kdeveloprc, it will reappear consistently. In Sublime::MainWindow::loadSettings() its visibility will be set to false, which also allows me to set a conditional breakpoint in QWidget::setVisible() to catch subsequent changes. And indeed, a bit later I get a whole series of hits with the backtraces below, suggesting that its a plugin restoring its view settings that causes this. Could that be the debugger plugin itself or is it just the plugin load order and what its idea bout debugger toolbar visibility is that determines whether it will ultimately be visible? If so, why do so many plugins store a visibility state for this toolbar, and what can be done about it? This basically means that the toolbar's effective visibility at startup is almost purely random, and that doesn't apply for other toolbars. 1st: * thread #1: tid = 0x1ba872e, 0x000000010cdc69f8

I've changed the bug title because I think that same multi-level restore apparent from the backtraces above causes other items to be restored when they shouldn't. For instance, I have been trying to get rid of the "Documentation" toolbar item because I don't use it (for a large part because using it tends to make its window reappear persistently). The "Documentation" toolbar item also keeps restoring itself. In fact, it does that much more persistently than the debugger toolbar: 1- open a session in KDevelop 2- remove the DOcumentation button from any toolbar it may be on, in all areas (code, review, debug) 3- quit KDevelop 4- restart KDevelop 5- back to 2)
Bump. I changed the title once more and the concerned component to the one I think is the culprit. The debugger tool continues to make itself visible and move to its apparently default location at random occasions in sessions where the debugger plugin hasn't been disabled completely. The Documentation toolbar item continues to reactivate itself *systematically* each time I restart a session, and continues to slide open its view after each area change on one of my systems. In addition, the view doesn't remember the width to which I resized it but will reopen *systematically* to take up almost half my editing area. I'd tackle this myself, but I haven't managed to find out even where to start. The only thing I have figured out is that areas apparently restore all toolviews multiple times, with the correct restore configuration at or near the start of a loop over (IIUC) individual plugin configuration settings. That explains why the final restore result can change, due to differences in the order in that loop changes, or if a random other session changed the settings for a plugin. In fact, if this interpretation is correct it's almost a miracle that one can get configuration changes to "stick" at all. Re-reading my comment 1 above it may be that we simply need to call Sublime::MainWindow::loadSettings() to restore the current session settings once more to override any changes made during the first call to that method, but where?
