96376 - Support tooltips in outliner

Status: RESOLVED FIXED

(Core :: XUL, defect)

Description

[Suresh]

It would be good if we support tooltips in outliner. I'm pretty sure lots of 
components can take advantage of this one.

Somehow, we should be able to have outliner detect that the mouse is hovering 
over a cell, and call back into the application via some interface, passing it 
some data that identifies the cell and asks for tooltip text to be displayed.

fixed

To use tooltips in outliner, do something like this:

    function showTooltip(aEvent, aTooltipNode)
    {
      var outliner = document.getElementById("outliner");
      var bx = outliner.outlinerBoxObject;
      var row = {}; var col = {}; var obj = {};
      bx.getCellAt(aEvent.clientX, aEvent.clientY, row, col, obj);
      aTooltipNode.label = "cell " + row.value + ", " + col.value;
    }

...

  <tooltip id="aTooltip" onpopupshowing="showTooltip(event, event.target);"/>

  <outliner>
    <outlinerbody tooltip="aTooltip"/>
  </outliner>
