Hi,
First of all you need to keep a handle on the controls object that you
create then you can simply query it when asked to perform the popup.
Provided your controls class has java.awt.Component as an ancestor then
something like this should do it :
public class My3DApp
{
private controls ctrl = null;
... All your other code
public void controlsPopup()
{
if (ctrl == null) // Check if ctrl has been created yet, if
not then create a new instance
{
controls ctrl = new controls();
this.toFront(); // keeps the focus with the main 3D app
}
else if (!ctrl.isShowing()) // If ctrl exists but is not
being displayed then show it on screen
{
ctrl.setVisible(true);
this.toFront(); // keeps the focus with the main 3D app
}
// Only other case is that ctrl is already visible so do
nothing
}
}
