Hi Janak,
thank you for your hints, I could solve with this all my
requests.
to focus the previous component with ctrl+tab from ulctextarea i
did the following:
Set backwardTraversalKeys = new HashSet();
backwardTraversalKeys.add(KeyStroke.getKeyStroke(KeyEvent.VK_TAB,
java.awt.event.KeyEvent.SHIFT_DOWN_MASK));
getBasicTextArea().setFocusTraversalKeys(KeyboardFocusManager.BACKWARD_TRAVERSAL_KEYS,
backwardTraversalKeys);
the similar way like your example:
....
InputMap im = text.getInputMap(JTextArea.WHEN_FOCUSED);
KeyStroke tabForward =
KeyStroke.getKeyStroke(KeyEvent.VK_TAB
,java.awt.event.KeyEvent.SHIFT_DOWN_MASK);
Action tabAction = new TabAction();
table.getActionMap().put(im.get(tab),
tabAction);......
did not work, because the actionperformed-Event did not fire,
but anyway it's running with the code above.
-------
for ulctable i did the same
----------
to disable the pageUp/down key from ulctextarea i did the
following:
InputMap map = (InputMap)
UIManager.get("TextArea.focusInputMap");
javax.swing.KeyStroke keyStrokePageUp =
javax.swing.KeyStroke.getKeyStroke(java.awt.event.KeyEvent.VK_PAGE_UP,
0);
map.remove(keyStrokePageUp);
javax.swing.KeyStroke keyStrokePageDown =
javax.swing.KeyStroke.getKeyStroke(java.awt.event.KeyEvent.VK_PAGE_DOWN,
0);
map.remove(keyStrokePageDown);
with this i have the right behaviour to scroll the whole
scrollpane and not the ulctextarea.
------------
"
>Is there a property or sth like this to scroll a scrollpane
>automatically down when the user goes down the page by tab?"
With this i have this behaviour:
ULCComponent.addFocusListener(new
com.ulcjava.base.application.event.IFocusListener() {
public void
focusGained(com.ulcjava.base.application.event.FocusEvent e) {
ULCComponent.scrollToVisible();
}
public void
focusLost(com.ulcjava.base.application.event.FocusEvent e) {
}
});
Thanks and Greetings,
Marco

For all of the above, see the snippet below.

Please explain the above.
