public void setCursor(int cursortype);

is a method in the class Frame in the package awt.

The arguments that can be given are:

Frame.DEFAULT_CURSOR
Frame.CROSSHAIR_CURSOR
Frame.TEXT_CURSOR
Frame.WAIT_CURSOR
Frame.SW_RESIZE_CURSOR
Frame.SE_RESIZE_CURSOR
Frame.NW_RESIZE_CURSOR
Frame.NE_RESIZE_CURSOR
Frame.N_RESIZE_CURSOR
Frame.S_RESIZE_CURSOR
Frame.W_RESIZE_CURSOR
Frame.E_RESIZE_CURSOR
Frame.HAND_CURSOR
Frame.MOVE_CURSOR

In java 1.1, there are api called setCursor() and getCursor().  They are defined in the class java.awt.Component, therefore all the classes extend from java.awt.Component can use the above 2 apis to handle the cursor matter.  The api using java.awt.Cursor as parameter and return value.  There are some defined cursor shapes in the class java.awt.Cursor.

In java 1.0, there are api called setCursor() and getCursor() as well, but they are defined under java.awt.Frame.  Therefore only the class extended from java.awt.Frame can use that api.  It introduced problem for a class extended from java.awt.Component, like Button, to change cursor shape.

However, we can use the api getParent() to find out the Frame castable container and then set the cursor.

e.g.
Frame getFrame(Component comp) {
  while(!(comp instanceof Frame) && comp != null) {
    comp = comp.getParent();
  }
  return (comp == null) ? null : comp;
}

So if I am using an Applet I am outta luck because there's no Frame to cast to, is that right??

An applet certainly can have a frame. But it doesn't need to.
So, if you're in 1.0.2, and you don't have a frame,
there is no apparent solution.

Would the above solution work on a mouseOver, if I were using Java Script in Netscape?  I can change it quite easily if I'm in IE.

Thanks!
