A Rich UI combo widget defines a combo box, which presents one of several selectable options and lets the user temporarily open a dropdown list to select a different option.
package client; import org.eclipse.edt.rui.widgets.Box; import org.eclipse.edt.rui.widgets.Combo; import org.eclipse.edt.rui.widgets.TextField; import eglx.ui.rui.Event; Handler MyHandler Type RUIHandler { initialUI = [myBox] } myBox Box{columns=2, children= [myCombo, myTextField]}; myCombo Combo { values = ["one", "two", "three", "four"], selection = 2, onChange ::= changeFunction }; myTextField TextField {text = myCombo.values[myCombo.selection]}; Function changeFunction(e Event IN) myTextField.text = myCombo.values[myCombo.selection]; end end
The first string in the array is at position 1, not 0.
The functions getSelection and setSelection are available; but in most cases, retrieve a value or assign a value to the selection property rather than invoking a function.
Other supported fields and functions are described in the following topics in the EGL Programmer’s Guide: “Rich UI widget fields” and ”Rich UI widget functions.”
