@hassene Hi and welcome Is there a reason you simply dont use a layout ? To make it autofollow the size of window ? if you place a QLabel on a form ( mainwindow.ui) , right click somewhere on empty form, and select Layout menu and select layout, the label will follow maniform. https://doc.qt.io/qt-5.10/examples-layouts.html

Ah, i see from your deleted post what you say. When QListWidget is clicked first time, it receives focus When you then click a button, that button is now given focus. Focus is not the same as selected for QListWidget.- one or more item can be selected. You can try qDebug() << ui->listWidget->currentItem()->text(); in button.

Also note that Qt 5.4 was released before VS2015 came out, you should use at least Qt 5.6 with this compiler

@M4RZB4Ni Hi its all in here http://doc.qt.io/qt-5/qscrollbar.html#details But connecting to a random widget will do nothing. IF u have this case, user click on Tab In tab there are many widget so he need to scroll to see last of them, then u just use a scroll area and put all stuff inside. then it will just work. ScrollArea have scrollbars. U can control if both horz and vert or just horz.

@SGaist So, last week our integrator had a moment of lucidity, and realized that we were actually using a debug-version of moc.exe instead of a release-build........... I did a quick test with a release build of moc.exe, which took the exact same measurement I mentioned above back to 1m10s, so indeed faster than with the 5.4-version, as you expected.

If you have the need to show tabular data on two columns then yes QTableView is the right tool. After that, what kind of model will you be using ? How much data will be shown ? Depending on that QTableWidget might be enough.

Hi, After digging the issue, the cause was related with permission in folder /dev/galcore (in my case, galcore is the Vivante GPU driver). To test the solution, you could change the owner of the folder as below: sudo chown -R username:group /dev/galcore To obtain the root cause, you could perform the following test: strace yourapp -platform eglfs ... open("/dev/galcore", O_RDWR) = -1 EACCES (Permission denied) open("/dev/graphics/galcore", O_RDWR) = -1 ENOENT (No such file or directory) --- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0xd4} --- +++ killed by SIGSEGV +++ Segmentation fault Julio

Since the obvious answer to the question is a resounding 'no', I'll mark this question as 'solved', although I'll still have to think about a way to achieve what we want in the most convenient way.

Do a small search on the forum, there was already a thread about Qt-VLC last week that might help you.

I've checked, there's currently no option to do it directly with Qt Multimedia. You might want to check the QtAV project.

@jsulm I add a button even as below. void Dialog::on_pushButton_clicked() { SubView *QQ=new SubView(this); QQ->setModal(true); QQ->setEnabled(true); QQ->showNormal(); } Then, I put a QEditline on the subview . Of course, subview is a class inherited from the dialog. This is a very simple code. Or You can try this https://github.com/mkdh/QEditlineOnNewWidgetiOS

Easy: just edit the thread title and prepend [solved] :)

Did you try setting antyaliassing? http://doc.qt.io/qt-5/qpainter.html#setRenderHint

@juanki Gracias!

Can you show your class and its implementation ?
