Drag and Drop from System to Java

[dominic]

Hi,

I'm writing a program to accept dragging files from the OS (I'm using
Windows) to my Java application. Everything works fine, excpet that the Java
window cannot get the focus when drag enter/over. I tried to put

frame.requestFo cus();

in my DropTargetListe ner, but it still doesn't get the focus. I'm sure that
the code is being processed (I changed it to setVisible(fals e) and it
works!). So is it a constraint of Windows or what? Thanks.

In the api it says this:

"Because the focus behavior of this method is platform-dependent, developers
are strongly encouraged to use requestFocusInW indow when possible."

.......don't know if that'll help?

The result is still the same : (
In the dragOver function I used requestFocusInW indow(), and it returns true
but the window doesn't really get the focus.

But thanks anyway!

If you're using Swing components, you may try to use the
javax.swing.Swi ngUtilities.inv okeLater() method to do the requestFocus
asynchronously, after all events have been processed.

Admittedly, I was dragging between frames in my own app, but I found
that this forced the frame to the top...
Window w = SwingUtilities. getWindowAncest or(HierarchyPan e.this);
if (w != null) {
w.show();
}

In the dragEnter method of my dropTargetListe ner.
