Model problem with delegate #1004

Closed Guitronic closed 2 months ago

Guitronic commented 2 months ago

If we use the ObjectBroker::model("com.kdab.GammaRay.ObjectInspector.properties") model, if we look for the value of a field that uses a delegate to display a checkBox, we receive an invalid QModelIndex.

I found an acceptable solution, you have to use the Qt::EditRole role. For example with the QPushButton avec 'text 'property:

role: Qt::DisplayRole QVariant(QString, "Hello World!")
role: Qt::EditRole QVariant(QString, "Hello World!") And for 'enabled' property:
role: Qt::DisplayRole QVariant(Invalid)
role: Qt::EditRole QVariant(bool, true) <== Good The Qt::EditRole is an acceptable solution. Thank you, I am closing the ticket
