CXTPControlComboBox + tree - how?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello,

I would have to create the combobox to use on a toolbar, that will display a tree in it's popup area - something like this.

This one was hacked together from the CComboBox and MarkupTreeCtrl from the samples.

However it would be nice to have it look like the CXTPControlComboBox.

I have tried to make the similar control using CXTPControlComboBox as a parent, but have a problem finding the way to display the tree on a popup bar.

I can't derive the popup bar from both CMarkupTreeCtrl and CXTPControlComboBoxPopupBar because both classes have CWnd as a base class.

For some reason I can't subclass the popup window - probably this is a stupid idea anyway.

Is there a way to make a custom popup control for the combo box?

	Hi, I've just avoided the requirement of the control of such kind :)
