This involves:
 - modifying WindowDraggingUtils.jsm to support panels as well as windows
 - hooking this up if some attribute is set on the panel
 popup's moveTo method

<method name="moveTo">
        <parameter name="aLeft"/>
        <parameter name="aTop"/>
        <body>
        <![CDATA[
          this.popupBoxObject.moveTo(aLeft, aTop);
        ]]>
        </body>
      </method>
  
uses popupBoxObject property

<property name="popupBoxObject">
        <getter>
          return this.boxObject.QueryInterface(Components.interfaces.nsIPopupBoxObject);
        </getter>
      </property>

which calls QueryInterface every time without a reason, making everything slow

so making lazygetter for popupBoxObject is needed for this too

This new code seems unreachable, since MozMouseHittest is used instead of mousedown in the XP_WIN case.

That doesn't work this way anymore, we changed this in bug 624157.

smaug, sicking, jst or bz should probably review the change to beginWindowMove.

r+ for the dom/ part.


Is 'backdrag' such attribute that it can be set only before ctor has
run? Is there some way to disable the feature for sometime and then
enable it again?

There isn't a way to modify it currently. I can add that in a followup bug.

WindowDraggingUtils.jsm doesn't seem to handle elements inside of panels in a sensible way. This can be taken care of in a separate bug (I could do it in bug 574971).

>+        if (isPanel) {
>+          var screenRect = this._elem.getOuterScreenRect();
>+          this._deltaX = aEvent.screenX - screenRect.left;
>+          this._deltaY = aEvent.screenY - screenRect.top;
>+        }

>+        if (this._draggingWindow) {
>+          var toDrag = this.isPanel() ? this._elem : this._window;
>+          toDrag.moveTo(aEvent.screenX - this._deltaX, aEvent.screenY - this._deltaY);
>+        }

To clarify before I begin writing: this is about the new "backdrag" attribute on the XUL panel element, correct?

    
    

    
  
Yes, setting backdrag="true" allows the panel to be moved around on the screen by dragging on a background area of the panel.
