Class JXTreeTable.TreeTableHackerExt2

  • Enclosing class:
    JXTreeTable

    public class JXTreeTable.TreeTableHackerExt2
    extends JXTreeTable.TreeTableHackerExt
    Patch for #471-swingx: no selection on click in hierarchical column outside of node-text. Mar 2007.

    Note: this solves the selection issue but is not bidi-compliant - in RToL contexts the expansion/collapse handles aren't detected and consequently are disfunctional.

      • expandOrCollapseNode

        protected boolean expandOrCollapseNode​(int column,
                                               java.util.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
