jjb,
Thanks for the quick answer.
for the moment, i managed to do this :
- create a totally new panel
- when something is selected in the html panel and i switch to my panel, the
xpath is displayed thanks to a domplate called in showPanel (the selected
element is found thanks to FirebugContext.getPanel('html').selection)
- add a little delete icon on the left of the xpath address to delete it
(thanks for the idea)
i'm trying now to move this to a side panel of the html panel as you suggested.
Everything works fine but i need to switch between my panel and another one
everytime for the selection to be taken into account (since i use showSidePanel
method).
I've had a look a codeburner extension but couldn't figure out which method is
called when selection is changed. I've also looked at bindings, but this is a
complete mistery to me (i don't even understand what's it is used for, but i'm
a complete newbie in XUL)
Is there a method that would be called magically in my side panel when the
selection changes in the html panel? I thought updateSelection (which i found
in css.js) would be a good candidate but it does not seemed to be called.
I've seen some code bindings in a11y.js such as bind(this.onHTMLFocus, this);
but i didn't have more luck.
Thanks for your help
Greg
