I have three different jtable on three diffenernt jscrollpane - one next to the other.
I successfuly written some code that makes them all scroll together when I scroll the mouse wheel.
I inherrited JScrollpane and overriden its processMouseWheelEvent methos as follows:
public void processMouseWheelEvent(MouseWheelEvent e) {
...
if (e.getSource() == this) {
for (BTSJScrollPane other : effected) {
other.processMouseWheelEvent(e);
}
}
}
I have canelled the pageup pagedown using
final InputMap inputMap =
comp.getInputMap(JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT);
inputMap.put(KeyStroke.getKeyStroke("PAGE_DOWN"), EMPTY);
inputMap.put(KeyStroke.getKeyStroke("PAGE_UP"), EMPTY);
comp.getActionMap().put(EMPTY, emptyAction);
But,
my only problem now is that when the user clicks up and down, they dont go together but rather scroll indipently.
Any suggestions ?
So far I wrote in my scrollpane something like
KeyboardFocusManager.getCurrentKeyboardFocusManager().addKeyEventDispatcher(new KeyEventDispatcher() {
@Override public boolean dispatchKeyEvent(KeyEvent e) {
if (thisIsThesourceTable) {
if (e.getKeyCode() == 38 || e.getKeyCode() == 40) {
}
}
return false;
}
});
But :
1. is there a better way?
2. maybe I should do it somehow in the actionMap?
3. how do I pass the key up/down event to the other scrollpane?
4. can I know if I am near the end of the viewing part in the scroll pane? is it needed
