Revision 7049
Date: 2012-01-11 15:09:16 -0800 (Wed, 11 Jan 2012)
Author: Paul
Trac: http://trac.dabodev.com/changeset/7049
Changed:
U trunk/dabo/ui/uiwx/dHtmlBox.py
Log:
Enhanced dHtmlBox to allow link hrefs to refer to application or
form methods. For instance, I have this html in the dHtmlBox,
which is a listing of orders and payments:
<li><a href="app://showOrder?11234">Order 11234</a></li>
<li><a href="app://showOrder?11235">Order 11235</a></li>
<li><a href="app://showPayment?9932">Payment 9932</a></li>
When the user clicks on the first link ("Order 11234"), the following
code will be executed:
self.Application.showOrder("11234")
This is basically allowing me to make html drill-down reports.
