KMenu has a signal:aboutToShow() and you also can have a handle to
everything in your menu.

For instance I want to change the title of the menu dynamically so I have
something like this:

Create a handle to the title:

 popupMenuTitleAction =
    (KAction *) my PopupMenu->addAction(KIcon(":images/image.png"),
                       "generic  Title");

Then in a slot connected to the aboutToShow signal I can modify the title
with:

popupMenuTitleAction->setText(str);


I see no reason why you can't also use this technic  to dynamically create a
new menu and show it.  I t would be best to create the one, or two menu
types ahead of time and just change the text where necessary. I assume what
you are changing on the fly is a rather finite number of actions, else it
might be kind of bewilding to the user to be getting a random popup menu

Hope this helps
David

<br>
I&#39;m trying to create a dynamic service menu for dolphin. Think of it<br>
like a &quot;Send file to &gt;&quot; menu-item which opens a sub-menu with a list \

<br>
Is there a way to do the above (create dynamic service menus) or will I<br>
have to create some sort of dialog which lists the contacts?<br>
NB: my problem is _not_ how to get the data through DBus or how to<br>
create simple service menus, that&#39;s all working already.<br>

Thanks<br>
