SUMMARY
You can programmatically clear a UIChoice selection by setting its selected index to -1.



MORE INFORMATION
The sample code below demonstrates how to use setSelectedIndex(-1) to clear the item currently selected in the UIChoice. Compile and run the program, select an item in the UIChoice control, then click the "Clear UIChoice" button. This results in the setSelectedIndex method getting called with a value of -1, clearing the previously selected item from the UIChoice control.

Sample Code
import com.ms.ui.*; import com.ms.ui.event.*;

public class ResetUIChoiceDemo implements IUIActionListener { UIChoice choice=null;

public ResetUIChoiceDemo(UIChoice choice) { this.choice=choice; }

public static void main(String args[]) {   UIFrame frame = new UIFrame("AFC Frame"); frame.setSize(320,50); frame.setLayout(new UIGridLayout(0,2)); UIChoice choice=new UIChoice; choice.addString("ChoiceA"); choice.addString("ChoiceB"); choice.addString("ChoiceC"); choice.addString("ChoiceD"); frame.add(choice); UIPushButton clearButton=new UIPushButton("Clear UIChoice"); clearButton.addActionListener(new ResetUIChoiceDemo(choice)); frame.add(clearButton); frame.setVisible(true); }

public void actionPerformed(UIActionEvent e) { choice.setSelectedIndex(-1); // Clear the UIChoice selection. } }
