public class JXTreeTable.TreeTableHackerExt3
extends JXTreeTable.TreeTableHackerExt2

A more (or less, depending in pov :-) aggressiv hacker. Compared to super, it dispatches less events to address open issues.

Issue #474-swingx: double click should start edit (not expand/collapse) changed mightBeExpansionTrigger to filter out clickCounts > 1

Issue #875-swingx: cell selection mode changed the dispatch to do so only if mouse event outside content box and leading

Issue #1169-swingx: remove 1.5 dnd hack removed the additional dispatch here and changed in the implementation of hackAroundDragEnabled to no longer look for the system property (it's useless even if set)

Method Detail

expandOrCollapseNode

protected boolean expandOrCollapseNode(int column,
                                       EventObject e)

Description copied from class: JXTreeTable.TreeTableHacker

Tricksery to make the tree expand/collapse.

This might be - indirectly - called from one of two places:

1. editCellAt: original, stable but buggy (#332, #222) the table's own selection had been changed due to the click before even entering into editCellAt so all tree selection state is lost.
2. processMouseEvent: the idea is to catch the mouseEvent, check if it triggered an expanded/collapsed, consume and return if so or pass to super if not.

widened access for testing ...

Overrides:

Parameters:

column - the column index under the event, if any.

e - the event which might trigger a expand/collapse.

Returns:

this methods evaluation as to whether the event triggered a expand/collaps

mightBeExpansionTrigger

protected boolean mightBeExpansionTrigger(EventObject e)
