I’ve been trying to create a custom combo box component but I’ve been having difficulty triggering the visibility of the popup. What other component (other than JPopupMenu) can I use to display the combo box’s items regardless of the size of the container of the combo box?
I’ve been trying to work my way through the source for JComboBox, but I can’t seem to figure out how they show / hide the popup.
How can I do this?
Use a JWindow or undecorated JDialog.
