Subject: [Qt-creator] [Dev] Bumping the minimum Qt version required to build
 Qt Creator
Message-ID: <A7AA355E-FC8A-4998-B504-97CD91FCE3A0@qt.io>

We plan to bump the minimum Qt version required to build Qt Creator to Qt 6.8.3. (The Qt version that can be used to build user applications is not affected.)
That makes it easier for us to keep the QtTaskTree implementation in sync (until we can completely switch over to the version in Qt),
and allows us to remove a couple of workarounds.

Patch open for comments here:
717575: Bump minimal version to Qt 6.8.3 | https://codereview.qt-project.org/c/qt-creator/qt-creator/+/717575

and some cleanup here

Subject: [Qt-creator] Bookmarks across multiple instances of Qt Creator?
Message-ID: <PAWPR05MB10062F607176777F17C5E45E19348A@PAWPR05MB10062.eurprd05.prod.outlook.com>

Hi all,

bookmarks in Qt Creator are pretty important to me. They were important enough that I enabled file history so I could recover them in the (so far rare) cases where they simply disappeared for unknown reasons.

/digression
Now I noticed that Creator isn?t well suited to work on the same project in different branches. It is simply too easy to open a file the in the wrong branch and edit it. If the locator has a filter, I?m not aware of it. The search dialog is certainly not equipped for branches: When I want to select a single project to search in, I can choose between ?MyProject?, ?MyProject? or ?MyProject?. No branch name given ?
/end digression

Anyway, the perfect solution to me is working in multiple windows. Everything works for the branch I?m currently working on, switching between windows is easy and clear.
But since Qt Creator is storing bookmarks in a config file, I?m really worried I?ll run into ?last instance to close wins? kind of scenario. And I?d like to know before that happens.

And no, I don?t want to organize my branches in different sessions with separate bookmarks. I switch branches so often, the session system simply isn?t suitable for that. And I want all my bookmarks in one place.

So?
1)  Do I have to expect trouble with bookmarks running multiple instances?
2) If so, what are good ways to work around them?

Cheers and thanks for a great IDE, despite the mentioned shortcomings!

Robert

I can see that it is inconvenient that the project name is not deduplicated if you open the project from multiple different locations.
Even though the branch is shown in the project tree, that doesn?t seem to be propagated to other places?
I?ve created https://qt-project.atlassian.net/browse/QTCREATORBUG-34308

Bookmarks are in principle saved in the _session_. In principle you are right that "last Qt Creator instance wins", but if you use different sessions for different branches of the project you should be fine in this case.

> 2) If so, what are good ways to work around them?

Otherwise the main workaround for settings clashes is to use Qt Creator with different settings by passing "-settingspath <alternative_settings_basepath>" when starting one of the instances. But as said above, for bookmarks you should be fine with separate sessions.

Many thanks for the reply!

I'll give the "multiple sessions" one more try. In my first attempt, it removed all the bookmarks from my default session file. I believe, this feature is also not designed with multiple instances in mind.

Also, I actually would prefer my bookmarks to by synced across instances, since I switch branches several times a day. I cannot say that a certain session is attached to a certain branch.
The bookmark I set in session A might become very relevant in session B a few days later, and it's rather tedious search in all bookmarks in all instances.
But I guess this is just not possible at the moment.

Kind regards

Robert
