GtkFlow

Here you see libgtkflow, a universal library for drawing flow graphs with Gtk+ 3.

GtkFlowRes

The newest stuff in libgtkflow's development ↑ Nodes can be deleted by clicking the X-button in the upper right corner. Nodes are resizable by drag-n-dropping the lower right corner. The types of the docks can be printed along with their names

Flow graphs are a possibility to let your user model flows of data from, through and into several stations.

Motivation

I love Flowgraphs in other programs and i want to have them in my favourite UI-toolkit Gtk. I ran into some programs which implemented similar functionality but they all didn't feel or even lokk very Gtk-like/GNOMEy.

Possible Usages

Specific:

Unspecific:

  • Video Compositing (maybe PiTiVi)
  • Visualizing dependencies of objects (e.g. debian packages in apt)

  • … and whatever you can think up.

Stability

Consider the API unstable for now. You will encounter bugs.

Building

Make sure you get the following Dependencies:

  • libgtk-3-dev
  • gobject-introspection
  • cmake
  • vala

Then do the following:

$ cmake .
$ sudo make install

Examples

libgtkflow supports GObject-Introspection which means you can consume it in various popular languages including but not limited to: Python, Perl, Lua, JS, PHP. I compiled some examples on how to program against the library in Python in the examples-folder.

Feel free to add examples for your favorite language.

Note: If you installed the library in /usr/local, you have to export the following environment variables for the examples to work:

$ export LD_LIBRARY_PATH=/usr/local/lib 
$ export GI_TYPELIB_PATH=/usr/local/lib/girepository-1.0/
