Object PmgWCombo (ComboBox)

Description:
The object serves for entering value by the selection from the list of pre-defined values. The selected value can be either an index, visible text or invisible value - see "The selected value is" configurator. The list can be displayed in the running application by the Alt+Down keys, texts can be selected by the Down/Up keys.

The selected choice is stored in the SelectedIndex, SelectedText and SelectedValue properties. If the selected value has a data binding, then the value is written into the variable referred to by the data binding on changing the ComboBox value respectively in the time that is set on the "Attributes" page (on the Enter key, on the selection from the menu, etc.). The data binding is here "for read and write", it means that if the variable of the data binding is changed even by other methods, then the change of this variable is reflected into the change of the ComboBox value.
