AutoMoc: The Property will be invalid

xavierbaez

Hello. This is some of the other things that started to happen after Qt5=>Qt6 upgrade.

The source code is:

namespace  WABAS::ViewModels
{

class CalibrationFilesView : public TableViewModel {
    Q_OBJECT

    Q_PROPERTY(int currentFileIndex WRITE setCurrentFileIndex)
    Q_PROPERTY(QAbstractTableModel* currentData READ currentData NOTIFY currentDataChanged)
    Q_PROPERTY(QString title READ title NOTIFY titleChanged)

The problem is:

warning: Property declaration currentFileIndex has neither an associated QProperty<> member, nor a READ accessor function nor an associated MEMBER variable. The property will be invalid.

You need a READ function according the docs: https://doc.qt.io/qt-6/properties.html

Q_PROPERTY(type name
           (READ getFunction [WRITE setFunction] |
            MEMBER memberName [(READ getFunction | WRITE setFunction)])

@Christian-Ehrlicher I tried now I got more errors:

return-statement with a value, in function returning ‘void’ [-fpermissive]
  145 |     return _currentFileIndex;

@Christian-Ehrlicher Okay I was able to fix it creating a function

currentFileIndex()
