Hi, Which part of your code triggers this error ?

@Pythonic-person You can use stylesheet and the pressed indicator/subcontrol https://doc.qt.io/qt-5/stylesheet-examples.html#customizing-the-qpushbutton-s-menu-indicator-sub-control

This is what I 've done and seems to work: bool ArticlesModel::setData(const QModelIndex &index, const QVariant &value, int role){ int nameColumnIndex = 1; int name_lowerColumnIndex = 3; if(index.column() == nameColumnIndex){ int row = index.row(); QModelIndex name_lower_index = index.model()->index(row,name_lowerColumnIndex); QString v = value.toString(); ArticlesModel::setData(name_lower_index, v.toLower(), Qt::EditRole); } return QSqlTableModel::setData(index, value, role); } Is it ok?

@ocgltd said in Is QAbstractItemModel re-entrant: I have it working now, but the view shows blank rows until the data arrives. Then you're doing something wrong. When no data is available, you should return '0' as row count... (already said at least three times).

@JonB (and to all of course) thank you for your time and effort! In python it works fine, I will try your code but I am sure it's fine!

By the way, there's also an equivalent for QtQick.

There's not need to go through the model, you already have the index and can retrieve the data from it. You can set the spacing QListView::setSpacing.

Dang, that was it. I swear I tried that yesterday, but I probably had it wrong as I was tired and throwing code around trying to make it work. Thanks once again for the help!

hi thanks for your topic, i have some more question about pcab , can u tell me how can i run this type of program in qt , in ubunto as administrator , and how to learn more??

@Pythonic-person said in What is the difference between these two layout assignee methods: are they the same? Yes, according to the documentation.

Quite possibly ensuring the compiler's binary folder (s) are in the PATH of the environment cmake is launched in. From the command line you ran the failing cmake from, does this run C:\Qt\Tools\mingw492_32\bin\gcc.exe -v

Hi, For your "menues", don't put them in a layout and manage their position manually. For the status bar: QStatusBar.

Good, then please mark the thread as solved so other forum users may know a solution has been found :-)

@Christian-Ehrlicher Okey, I will try it, thanks for the help :)

@EekTheCat perfect, thanks a lot

Yes! It built. Thank you for the help!!

Thanks for the suggestion. Moving my whole app to Qt6 to test that would have been a big job so I started making a minimum reproduction case. Using the examples as a starting point I noticed that they no longer use QGLWidget, instead using the newer QOpenGLWidget. I tried QOpenGLWidget for the minimum reproduction case and it worked ok. After modifying my app to also use QOpenGLWidget the mouseMoveEvent problem was solved. This also fixed some janky behavior where the MDI subwindow had not been responding to clicks on the traffic light buttons, and sometimes could not be dragged. It seems that QGLWidget remains only as a convenience for older code so is probably no longer being tested. https://www.qt.io/blog/2014/09/10/qt-weekly-19-qopenglwidget https://doc.qt.io/qt-5/qopenglwidget.html#details

@SGaist i did change a few things in the structure and now with signals and slots it works, thanks for the hint.
