Detailed Description

Combo box gadget.

Geometry:

• Same geometry as UTextfield: keeps its initial size, which is calculated to make the first item of the list entirely visible in the textfield.

List and Selection:

• list() returns the UListbox that was passed as an argument to the constructor
• choice() returns the UChoice object that manages the selection in list()

Callbacks

• UOn::action (default callback) is fired when an item is selected or re-selected and when the RETURN key is pressed in the textfield
• UOn::change is fired when an item is selected (if it was not already selected)
• UOn::strChange is fired when the text is changed in the textfield

Exemple

    XXX* obj = new XXX();
    UListbox& list = ulistbox( ... );   // see UList
    UCombobox& combo = ucombobox(list, 
                                 UOn::action / ucall(obj, &XXX::actionCB)
                                 + UOn::change / ucall(obj, &XXX::changeCB));
