To find the active Window(be it a frame or a dialog) in a java swing application you can use the following recursive method:
Window getSelectedWindow(Window[] windows) {
Window result = null;
for (int i = 0; i < windows.length; i++) {
Window window = windows[i];
if (window.isActive()) {
result = window;
} else {
Window[] ownedWindows = window.getOwnedWindows();
if (ownedWindows != null) {
result = getSelectedWindow(ownedWindows);
}
}
}
return result;
}
For the first call, pass in all the frames for the application with Frame.getFrames().
