[REVIEW REQUEST] Add text property to ComboBox

[Tadashi Ohmura]

Hello Jerome
I understand your opinion.
String type editable combobox is so common.
Such combobox has TextField for user key input.

What about a rough workaround code titled as TextField05 ?
we have two textfield in a VBox, and initial values set.
we directly type TAB to go to the next textfield.
Please press down array key on a textfield :-)
