I'm writing a plugin that is reusing the inspector code in firebug. Since I
need to change some of the behavior of how the inspector works, I thought
the best course of action would be to extend Firebug.Inspector and override
the functions I need to change. I started out with overriding
onInspectingClick, and I am not seeing the results I expect when moving the
mouse cursor around the page. I do see my sysout statement (FBTrace.sysout("**
QRUCIBL: onInsp[...])is showing up in FBTrace every time I click, but as I
mouseover, I do not see the highlighting nor is the HTML tab is scrolling
to dom element that the mouse is on top of. In addition, as I mouseover the
page, the error console repeatedly shows "TypeError: context is null \
Source File: chrom://firebug/content/html/inspector.js". Can anyone comment
on the errors of my approach and guide me to overcoming these problems?
Thank you!
*.../content/qruciblInspector.js:*
define([
"firebug/lib/lib",
"firebug/lib/trace",
"firebug/html/inspector",
],
function(FBL, FBTrace) {
Firebug.QruciblInspector = FBL.extend(Firebug.Inspector,
{
onInspectingClick: function(event)
{
if (FBTrace.DBG_INSPECT) {
FBTrace.sysout("onInspectingClick event", event);
FBTrace.sysout("** QRUCIBL: onInspectingClick event", event);
}
var win = event.currentTarget.defaultView;
if (win)
{
win = Win.getRootWindow(win);
this.detachClickInspectListeners(win);
}
Events.cancelEvent(event);
}
});
return Firebug.QruciblInspector;
});
The overridden inspector is called from a new panel I added. A button on
that panel executes the Firebug.QruciblInspector.toggleInspecting function
when clicked:
*.../content/myPanel.js:*
[snip]
/**
* Extends toolbar for this panel.
*/
getPanelToolbarButtons: function()
{
var buttons = [];
buttons.push({
label: "qrucibl.button.recordflow.label",
tooltiptext: "qrucibl.button.recordflow.tooltip",
command: FBL.bindFixed(this.onFlowRecord, this)
});
return buttons;
},
onFlowRecord: function()
{
Firebug.QruciblInspector.toggleInspecting(Firebug.currentContext);
}
