Enclosing class:

public class JXTreeTable.TreeTableHacker
extends Object

Temporary class to have all the hacking at one place. Naturally, it will change a lot. The base class has the "stable" behaviour as of around jun2006 (before starting the fix for 332-swingx).

1. hitHandleDetection triggeredn in editCellAt

public JXTreeTable.TreeTableHacker()

Method Detail

isHitDetectionFromProcessMouse

protected boolean isHitDetectionFromProcessMouse()

Decision whether the handle hit detection should be done in processMouseEvent or editCellAt. Here: returns false.

Returns:

true for handle hit detection in processMouse, false for editCellAt.

hitHandleDetectionFromEditCell

public void hitHandleDetectionFromEditCell(int column,
                                           EventObject e)

Entry point for hit handle detection called from editCellAt, does nothing if isHitDetectionFromProcessMouse is true;

See Also:

isHitDetectionFromProcessMouse()

hitHandleDetectionFromProcessMouse

public boolean hitHandleDetectionFromProcessMouse(MouseEvent e)

Entry point for hit handle detection called from processMouse. Does nothing if isHitDetectionFromProcessMouse is false.

Returns:

true if the mouseEvent triggered an expand/collapse in the renderer, false otherwise.

See Also:

isHitDetectionFromProcessMouse()

completeEditing

protected void completeEditing()

Complete editing if collapsed/expanded.

Is: first try to stop editing before falling back to cancel.

This is part of fix for #730-swingx - editingStopped not always called. The other part is to call this from the renderer before expansion related state has changed.

Was: any editing is always cancelled.

This is a rude fix to #120-jdnc: data corruption on collapse/expand if editing. This is called from the renderer after expansion related state has changed.

expandOrCollapseNode

protected boolean expandOrCollapseNode(int column,
                                       EventObject e)

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 ...

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)

expansionChanged

protected void expansionChanged()

called from the renderer's setExpandedPath after all expansion-related updates happend.
