Re: [ jEdit-users ] Horizontal scroll lock

[Dale A. <da...@gr...>]

The macro below will lock the horizontal scroll bar. Run it again to unlock
it. Copy it to your jEdit Settings/macro directory. To find your jEdit
Settings directory from jEdit, go to the Utilities menu, mouse over the
Settings Directory, and the actual directory location will be the first
menu item. Name the macro file name Toggle_Horizontal_Scroll_Lock.bsh. Then
you can run it from the macros menu or assign a shortcut to it.

Let me know if you have any problems with this.

(ScrollListener)textArea.getClientProperty(clientKey);
    if (scrollListener == null) {
        // scrolling not locked, set to locked
        int offset = textArea.getHorizontalOffset();
        scrollListener = new ScrollListener() {
            public void scrolledHorizontally(TextArea ta) {
                ta.setHorizontalOffset(offset);
            }
            public void scrolledVertically(TextArea ta){}
        };
        textArea.putClientProperty(clientKey, scrollListener);
        textArea.addScrollListener(scrollListener);
    }

        // locked, unlock scrolling
        textArea.removeScrollListener(scrollListener);
        textArea.putClientProperty(clientKey, null);
