General and Desktop

@mstoth I think this is normal: you often get complains from Valgrind about issues in system libraries or Qt in this case. You can just ignore them. See http://doc.qt.io/qtcreator/creator-analyzer.html#suppressing-errors

Thanks @VRonin.

Hello, my version was Qt 5.0.2 (32 bit) and I added the CONFIG +=c++11 in the project file, Thank you very much it worked properly. Best Regards,

Hi libVLC is always interesting. https://github.com/vlc-qt/vlc-qt It has filter for blending but not sure if fits your needs.

@king558 Oh so it did not recompile it by itself :) Sometimes one must run qmake manually.

@jsulm Thanks! It is fixed!

Instead of using a QLabel in a QListWidgetItem just call item ->setData(Qt::BackgroundRole,QBrush(QColor(Qt::blue));

You can find the list here. As I wrote before, your application might run on older version of macOS, but you'll have to try first.

@paladinmain No. This is wrong folder. Look one level up -> (for example) chess-game-Release\release Or look from Qt Creator: Projects -> Build Settings -> Build directory

Try the following: In your pro file: macx{ QMAKE_INFO_PLIST = Mac/Info.plist ICON = Mac/AppIcon.icns } In my case, the info.plist and icon files are in a folder called 'Mac' inside my project folder. In the info.plist file, you must have: <key>CFBundleIconFile</key> <string>AppIcon</string>

OK, I finally figure it out, It was dumb, I had to wait till the replica get sync with the source, and this by handling the QRemoteObjectReplica stateChanged event. and it's all OK now.

Thank you! I'll try it.

Sorry, I forgot to post the link: https://bugreports.qt.io/browse/QTBUG-61787

Nice :-) Happy coding!

@hskoglund Thank you! Yes, the problom is “\” , I create a key like "aaa/bbb/ccc"， QSettings can work well on it. Thanks a lot.

I solved that Problem. Sorry i forgot to mark the Thread. The Problem was the Index yes. In my data() Method of my TableModel i returned my Object wrong. So the Pointer was always null.

@KevinR said in Display multiline cells in QTableView with QSqlTableModel: Try this: void QStyledCustomDelegate::initTextDocument(const QModelIndex & index) { document->setHtml( index.data(Qt::DisplayRole).toString() ); document->setTextWidth( QWIDGETSIZE_MAX ); document->setTextWidth( document->idealWidth() ); } QSize QStyledCustomDelegate::sizeHint(const QStyleOptionViewItem &option, const QModelIndex &index) const { this->initTextDocument(index); return document->size().toSize(); } void QStyledCustomDelegate::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const { if( index.column() == XXX ) { this->initTextDocument(index); painter->save(); painter->translate( option.rect.topLeft() ); document->drawContents(painter); } else QStyledItemDelegate::paint(painter,option,index); } Note: the paint method is still lacking of the selection background.

@Dan3460 Well, you can create as many windows/widgets as you like at runtime. How exactly to do this depends on how you want to present the information to the user. Do you really want to use MDI? This concept as actually outdated. If you want to show same type of information then you can simply create a custom widget for it and then create as may instances of it as needed. Then put each instance in a layout and call show().
