OOBasic Popup menu Class

Postby JeJe » Wed Sep 12, 2018 1:09 pm

A class to help make creating a popup menu with submenus more easily

Create a module with this code and call it MenuCls

Slight updates to 13 09 18: Added support for radio button, bug fixed return value when no button clicked,switched ">" "<" for ticked and unticked

Code: Select all   Expand viewCollapse view

   'Class to help easily create menus with submenus
   'Items separated by *
   'separator is _
   'icon specified by a | and the end of the URL after the caption name eg |sc_cut
   '< as the first character specifies unchecked check item
   '> as the first character specifies a checked check item
   '{  as the first character specifies an unchecked radio button
   '}  as the first character specifies a checked check item
