Implementing ‘Got_focus’ Event in Smart Client
Q: Clear Basic provide ‘got_focus’ event for controls but I can’t find the same event in smart client.
Is there any way to implement this feature in smart client?
A: You can add your native contol focus event listeners (lost/gained) as follows:
(assuming your control is a textBox named ‘txtCustomerName’)
// Add the following in the form_Load() event handler: // define focus event listeners (lost/gained) ( (javax.swing.JComponent)this.txtCustomerName.getNativeControl()) .addFocusListener(new FocusListener()
{
// this is the equivalent to Clear Basic Lost_Focus()
public void focusLost(FocusEvent focusEvent)
{
// your logic here...
System.out.println("focus lost");
}
// this is the equivalent to Clear Basic Got_Focus()
public void focusGained(FocusEvent focusEvent)
{
// your logic here...
System.out.println("got focus");
}
}
);
