Line edit for QListWidgetItem?

CJha

Hi, is there a way I could get the QLineEdit for QListWidgetItem when it is being edited?
For example, for a QComboBox I can get the QLineEdit (if the QComboBox is editable) like this: ui.comboBox->lineEdit().

Can I somehow get the display of QVariant data?

OK, found out that it actually does show a QLineEdit widget, but only for editing...
You could try a custom (QLineEdit style) itemDelegate and set your wanted behavior there. Dunno if it will work.

Edit:
Yeah, that's probably it.
Set a itemDelegate and use a QLineEdit with some QValidator or whatever you need, to validate your input...

I dont think QListWidgetItem "includes" a QLineEdit. The item itself is the "display" for QVariant data...
Or did I get your question wrong?!

@Pl45m4 Thanks! No, you got it right.

The item itself is the "display" for QVariant data...

Can I somehow get the display of QVariant data? I just want to monitor as the user updates the text and change the color to red in case the user inputs a text that already exists. I cannot do that by changing the foreground of the item itself when the user is updating the text.

@Pl45m4 Thanks! I thought it would be as easy as accessing the QLineEdit for editable QComboBox. I will have a look at QItemDeligate.
