I am a Computer Science and Engineering student at "International Institute of Information Technology, Hyderabad"(IIITH) interested in GUI development for applications. Currently, I am involved in developing the PyGTK GUI of ASCEND.

GSoC 2012 project : GUI Improvements and Bug Squashing
The objectives of this project are
- Develop the Integrator window
- Add additional features to the PyGTK GUI
- Improve IPython console support to the PyGTK GUI
- Implement the "incidence graph" functionality in windows
- Enable Loading/Saving changed models
- Port the DISPLAY equivalent of the Tcl/Tk GUI to PyGTK GUI
- Add an exit prompt dialog box to the PyGTK GUI
- Bug fixing
- Add a sub menu for selecting display options to the "Diagnose" window
Module 5
- Patched up gtkbrowser.py to ensure that once a delete-event occurs(by clicking on the exit button on title bar), an exit pop-up fires up and asks the user to confirm his exit from the main window i.e, ASCEND browser.
- Used gtk.MessageDialog instead of gtk.Dialog because according to the docs at pygtk.org, gtk.MessageDialog saves a bit of time when used for trivial purposes(displaying an exit pop-up in this case).
- Ensured that the function do_quit() is called to perform the clean up procedures before exiting.
- Here is the link to the patch http://code.ascend4.org/viewvc/code/branches/sreenatha/pygtk/gtkbrowser.py?r1=4124&r2=4165&view=patch
- Here is an image of the exit pop-up
Module 4
- Added view items in the GtkMenuItem with id='filemenu_menu' and the GtkToolbar with id='toolbar3' using the Glade Interface Designer for linux
- Defined callback function 'view_click' in gtkbrowser.py for these added items
- Replicated from 'open_click', the code for displaying the window to choose/select the location of the model, in view_click
- Added a class 'ViewModel' to gtkbrowser.py which defines the view window that displays the actual content of the model selected
- Used
- gtk.Window for the view window
- gtk.VBox for the vertical box inside the window
- gtk.TextView for the viewing widget
- gtk.ScrolledWindow for the scrollable window
- The view window is the actual window that is displayed after selecting the file using a gtk.FileChooserDialog widget. It contains a vertical box container inside which is a scrollable window encapsulating the widget(gtk.TextView) that actually shows the content of the file.
- TextView widgets don't have scroll-down/up options. That is why, it is placed in a scrollable window.
- Used
- Initially tried editing the file ascend.glade in the directory pygtk/glade. Then, realized that editing the ascend.glade file at /usr/local/share directory made changes to the ascend browser(config.py helped).
- Added tooltips for the menu items of the filemenu(to which the view menu item has been added).
- Here is a patch for gtkbrowser.py http://code.ascend4.org/viewvc/code/branches/sreenatha/pygtk/gtkbrowser.py?r1=4168&r2=4175&view=patch
