Mouse cursor won't change when rolling over objects

I'm having an issue with a GUI I built. I'm trying to set different cursor changes when rolling over certain objects- i.e., hand cursor when hovering over buttons and text cursor when hovering over textfields. However, the appropriate code doesn't work. I've tried both the following codes:

classArmBtn.setCursor(new Cursor(Cursor.HAND_CURSOR));

And

classAlcBtn.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));

I know, however, that the reason the cursors won't change is because these objects are in panels that are nested within a JSplitPane. The JSplitPane, however, is disabled because I don't want it to be allowed to resize. Is there any way to maybe override a method and allow these cursors to change? Thanks!

Solution

  • The JSplitPane, however, is disabled because I don't want it to be allowed to resize.

    Another way to disable resizing is to disable the divider only and remove the MouseListener from the splitpane divider:

    BasicSplitPaneUI ui = (BasicSplitPaneUI)splitPane.getUI();
BasicSplitPaneDivider divider = ui.getDivider();
divider.setEnabled( false );

for (MouseListener ml: divider.getListeners(MouseListener.class))
    divider.removeMouseListener( ml );

    Now the cursor can be set since the component isn't disabled.
