QComboBox as editor in QStyledItemDelegate

[DonCoder]

1. The combobox editor has to be created wehn user presses enter/ mouse double click
2. The combo box is editable, So i should allow the user to change item of combo box using up/down arrow keys. and should close it when he presses enter
3. for mouse click i should close is when user selected any index.

Now i tried to handle currentChangedIndex for mouseclick. But this has an issue. when i changes item using arrow key the current changed Index is getting triggered and the ediotor is getting closed on currentChangedIndex signal... ANy Suggessions plzzz

QComboBox::activated()?

@ChrisW67 : Same with QComboBox::activated() , it is coming upon pressing up/down arrow

Looks like QComboBox::textActivated is what you want for the user selection part.

For the editing part, you should connect the QComboBox line edit editingFinished signal.

@SGaist Yes, But that is available from Qt 5.14. My Application is using 5.9 version. So is there an alternative that can mimic QComboBox::textActivated in Qt 5.9 ?
