Fwd: gtkmm-list Digest, Vol 80, Issue 2

[Chun Yang <achunyang2010 gmail com>]

Hi All,

Haven't received any feedback on my previous question. So I spent more time searching the web and found the palette example:
http://library.gnome.org/devel/gtkmm-tutorial/stable/toolpalette-example.html.en

But when I compile I got errors below:
[chun localhost pallette]$ make
g++ -o obj/Linux/main.o -c -Iinc `pkg-config gtkmm-2.4 --cflags` src/main.cpp
In file included from src/main.cpp:1:
inc/examplewindow.h:59: error: ‘ToolPalette’ in namespace ‘Gtk’ does not name a type
make: *** [obj/Linux/main.o] Error 1
[chun localhost pallette]$

Any ideas on what's going on?

For my previous question, what I want to do is when I drop the mouse-button, I want to get the tree item that received dragged data. Any function that I can use to get that infomation?

Thanks,
Chun

Hi All,

I am working on a project that has a treeview of items. The tree items can
be draged and dropped from one place to another. I got the tree view work by
following the examples.

Now I got one question:
In the process of drag&drop, I also want to operate on data structure
represented by the tree view. For example when one item is dragged and
dropped to another item, I want to remove the link to it from its old place
and add the link to its dropped place in a data structure behind the
treeview. How do I do this? What is the function to use? If you could point
me to some example that would be great.

Thank you very much!

Chun
