Patch for #471-swingx: no selection on click in hierarchical column if outside of node-text. Mar 2007.

Note: with 1.6 the expansion control was broken even with the "normal extended" TreeTableHackerExt. When fixing that (renderer must have correct width for BasicTreeUI since 1.6) took a look into why this didn't work and made it work. So, now this is bidi-compliant.

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:

expandOrCollapseNode in class JXTreeTable.TreeTableHacker

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

getTreeMousePoint

protected Point getTreeMousePoint(int column,
                                  MouseEvent me)

This is a patch provided for Issue #980-swingx which should improve the bidi-compliance. Still doesn't work in our visual tests...

Problem was not in the translation to renderer coordinate system, it was in the method itself: the check whether we are "beyond" the cell content box is bidi-dependent. Plus (since 1.6), width of renderer must be > 0.

Parameters:

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

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

Returns:

the Point adjusted for bidi
