@SGaist Its about precision moves, if user wants to move by tiny bit, scaling mouse movement by x value would allow that to happen. Else he would have to type 0.0001 0.0002 0.0003 etc etc. I think I could handle it using itemChange() and record initial mouse click press/release and calculate delta using that.. Yep that seem to do the trick... I can now move my items by tiny amount and doing "Long precise drags" deltaX = (newPos.x() - self.mMousePressPosition.x()) / 2 newPos.setX(newPos.x() - deltaX) deltaY = (newPos.y() - self.mMousePressPosition.y()) / 2 newPos.setY(newPos.y() - deltaY) Small edit, function above works for "simple" items, but as soon as I get to child items with parent it appear to break... sigh. Needs some more math there

Thanks for reply. I managed to solve this problem with the following: auto prepare_string = QString{ "DELETE FROM %1" }.arg(table); auto ok = q.prepare(prepare_string); auto ok = q.exec();

In TestClass, add a method: void moveToThread(QThread *thread) { connect(thread, &QThread::finished, &m_timer, &QTimer::stop); QObject::moveToThread(thread); } This will make sure when the thread the object is moved to terminates, the timer gets stopped by that thread.

@mrjj said in Drawing Frames arround Widgets: setContentsMargins(0,0,0,0); thats it! [image: a6191f58-0af9-4801-9f93-bed0058793e8.png] I thought i tryed it before but i think i tryed: setContentsMargins(0,0,0,0); and not layout->setContentsMargins(0,0,0,0);

@Ayush-Gupta ok, please consult the docs and make sure you are using it as intended. :) also check the index you use is valid etc.

anyone have any ideas or resolution to this issue?

@ThMars said in QtEndian: Thanks for the solutions. is your issue solved then? if so please don't forget to mark your post as such! Thanks.

@Asha please check response on this other post also from you PS: it'd be a good idea if you could stop double posting...

Re: Error compiling libqsqlmusql.so ( On Ubuntu) Hi All As i have predicted before, there was a very stupid error! It seems that db.setHostName("localhost:50000"); is not valid using QMYSQL, but is valid for QSQLITE i have replaced it with db.setPort(50000); db.setHostName("localhost"); And now i can connect to the db using the QMYSQL connector Sorry for bothering you! Thanks Cristiano

@CroCo I think this is you want it. [image: a0ad8d39-ce34-420f-891f-67c18d770bdb.jpg]

@SpaceToon said in Dummy backend running. Qt Bluetooth module is non-functional (Bluetooth Low Energy): So is it possible with the MSVC Compiler? No. You will need to build your code for Linux. It is better to do this on a Linux machine as cross compiling from Windows to Linux will be a lot of work. You can have a virtual machine with Linux to build for Linux.

Hi @pmh4514 , did you actually get your project working? We are curious to try just that, embedding a QGraphicsView (or a full QMainWindow) in a WPF GUI. Did it ever work for you?

@Pablo-J-Rogina Oh that was pretty quick and thank you. That was a bit confusing for me to understand, but the link you've shared is very useful. Thanks.

@hobbyProgrammer said in QGraphicsView MousePressEvent keeps looping: QGraphicsView::mousePressEvent(event); Why do you call this in a loop? Also, you should call accept/ignore on the event: https://doc.qt.io/qt-5/qevent.html

Ok, I see. Something like the QSplitter handle.

Hi and welcome to devnet, If you want to have a full static build, you'll have get the static librairies of all your dependencies.

@Daniel-Williams From what I can see, it's not like in e.g. MS stuff, you have to some work. See the code in https://stackoverflow.com/questions/56062025/search-for-nodes-in-a-qdomdocument-using-xpath. It's only 5 months ago, so I assume the answer is "current & correct". https://stackoverflow.com/questions/1286842/how-do-i-run-xpath-queries-in-qt looks like more work. As @mrjj said, there's also https://doc.qt.io/qt-5/qxmlquery.html#details, which works with XPath but not with QDomDocument, I think.
