[SOLVED]QTableWidgetItem, detect when it is changed

[Jake007]

Hi!

I have a class which inhertis_QTableWidget_. I'd like to detect all changes made to it's QTableWidgetItems. I've looked through docs, but I did not find any method that does that. Only thing I found are signals with which I can track current selected cell.
Can this be done with QTableWidget or will I have to either use models or inherit from QTableWidgetItem and write my own signals? ( But again, I haven't found any method that QTableWidgetItem has, to provide detection whenever it was changed).

Thanks in advance.

Regards,
Jake

Hi Jake,
You are correct, the signals are very useful in detecting any kind of change to your QTableWidget. Signals not only track current selected cell but following -

@
void cellActivated ( int row, int column )
void cellChanged ( int row, int column )
void cellClicked ( int row, int column )
void cellDoubleClicked ( int row, int column )
void cellEntered ( int row, int column )
void cellPressed ( int row, int column )
void currentCellChanged ( int currentRow, int currentColumn, int previousRow, int previousColumn )
void currentItemChanged ( QTableWidgetItem * current, QTableWidgetItem * previous )
void itemActivated ( QTableWidgetItem * item )
void itemChanged ( QTableWidgetItem * item )
void itemClicked ( QTableWidgetItem * item )
void itemDoubleClicked ( QTableWidgetItem * item )
void itemEntered ( QTableWidgetItem * item )
void itemPressed ( QTableWidgetItem * item )
void itemSelectionChanged ()
@

Remember the tablewidget items are not inherited from QObject and hence will NOT have signals.
The signals can hence be tracked from the QTableWidget.

Thanks

Hi!

I've found this but there is a lot of confusion. Most of them are just for tracking. After looking through it again, I noticed itemChanged(QTableWidgetItem *). I completely missed it.

Thanks!

Marked as solved.
