Open window on click on prop_dlgbuttonjqui

[#1]

In DynFullProperties, there is some standard behavior defined for click on button on the right side of each dimensions item.

Code is below:

<div class='prop-sortable-width-28px' propicontype='tool' avq='prop_dlgbuttonjqui:.:ExtensionDimDialog.qvpp'></div>

I would like to know how to chang the behavior for the action on click. I would like a web page to open inside QLikView document instead. For this purpose, should i change the Script.js ? or create a Custom properties.qvpp file ?

Could you hint at some example of an extension that redefines behavior on click on some button in the main properties pane ?
