Hi, all
The different columns of QTableView have set delegates, the table model is QSqlTableModel, and everything is working normally. According to the needs of the project, when QTableView is idle, its background color will change randomly. When double-clicking any cell to enter the editing state, its background color will stop refreshing.
I tried the “hasFocus” property, “entered” signal, and “viewportentered” signal, but the Editing State cannot be obtained correctly.
How do I know if a cell in QTableView is being edited, please?
Best regards!

In the delegate emit a signal just before returning from setEditorData

A delegate is always used. The default one is QStyledItemDelegate so you can just subclass it and only add the signal
