QComboBox signal when user types text and presses Enter

[Taytoo]

How do I get notified when a user types something in combobox edit box and presses enter? Tried editTextChanged but its fired each time a character is typed/erased.

Hi,

You can use the QLineEdit::editingFinished signal. QComboBox provides a getter for its QLineEdit that is available when in editable mode.

@SGaist Its working but combobox max item count is set to 5. I was hoping it will show the last 5 items in dropdown, however, once the dropdown fills up with 5 items then new items entered in the Edit are Not added. How do I change this behavior to mimic MRU?

Is it possible to have 2 sticky items i.e. they always stay in the dropdown menu But remaining 3 items are MRU?

Are you sure? You probably need to scroll in the drop down box to see new items at the bottom.

Yes, like I mentioned earlier, the problem is once you set maxCount (in my case 5) then no new items are added after 5 limit is reached. It keeps the first 5 items entered by the user, 6th, 7th etc items are not added.

Then (presumably) implement the desired behaviour yourself: keep the top 2 items, cycle the bottom 3 items as required when inserting a new item.
