Delphi PopupMenu replacing with 3rd party component. (Newbie)

Hi,

I am working on a soure code with TreeView component and with dynamically changing PopupMenu for this TreeView files and folders. However, I am required to change this Popupmenu with a 3d party Popupmenu with more fetaures and customization. I was able to replicate all previous Popupmenu Items onto the new one but the new 3rd party Popupmenu still lacks the basic (enabling/disabling menuitem) options for TreeView items.

I am unable to find information in source code to enable/disable menuitems on new Popupmenu for certain events for TreeView files/folders or even dynamically appearing new popupmenu-items for TreeView-items.

For example: for a TreeView item 'A' right clicking it displays Popupmenu with options (A and B) where 'A' is disabled (to select) and 'B' is enabled. But on new popupmenu both (A and B) are enabled all the time.

Thanks.

Thank you for your brief explanation. But I know the structure to work out the basics. But I am having problem finding the similar structure (used all possible means) in the original source code for a particular menu item.

My question is should I continue looking in the main sourcecode or menuitem with function can be loaded from a resource file?

Thank you for your reply.
