Select multiple items in a combobox

[d_stranz]

Can someone tell me how I can select multiple items in a combobox?

You can't. That's whole idea of a combobox: You click the arrow, it opens, you select a new item, it closes, and the new item is displayed in the edit box. What kind of behaviour would you expect if you could select multiple items? Which one of them would you display in the edit box?

If you think you need to select multiple items from a list, then you should be using QListWidget.

If you want the QxtCheckComboBox then use the Qxt library. Seems obvious enough.

Take this class QMultiComboBox

I implemented your class and it works well but appears in the layout looks like this:comboBox.png

How do I solve this?

And how can I increase the height of comboBox?

Set correct minimum size, re-implement and return correct sizeHint() and set resonable size policies.
You may want to look at minimumSizeHint() as well.

That seems like a reasonable solution to the UI problem I described earlier. Didn't realize I could stand up and see over the edge of the box.

QVariant QMultiComboBox::itemData(int row);

QVariant QMultiComboBox::itemData(int row);

To copy to clipboard, switch view to plain text mode 

This code is from QMultiComboBox.h; it returns QVariant(true) if the item in "row" is checked, QVariant(false) if it isn't. You should be able to figure out how to use that method in your own code.
