GTK+ offers a nice toolkit through the GDK library to make image manipulation quite easy.
This page will go through the process of modifying an image but putting another on on top as an overlay. In this example, we will be copying an MSN icon on top of a "busy" icon.
Another use case could be to watermark images.
Text completion is quite a nifty feature to have on an interactive software, saves you loads of typing, helps you remember the exact spelling on one's email, lost urls (thanks firefox 3 for the regex based search :-) )....
This tutorial will explain through a code sample how to set it up.
In the previous post, I showed how to customize your gtk.Notebook Tab Label by adding a close button to the tab.
Depending on the theme used by the user, the tab might get pretty big once a gtk.Button is added.
In this tutorial I will explain how to override the theme behaviour by creating a custom style for our widget.
gtk.Notebook is a great feature as it help keep your application footprint on the desktop occupation low. I personnally would not even think of using a web brower without a tab feature as it would take me a help of a time to go from one application to another.
A gtk.Notebook page is composed of a child widget and a label gtk.Widget. From there on, we can fit anything we like in a tab label such as an icon on the side representing the content, a title and a handy close button on the right side a bit like firefox's tabs.
This tutorial will detail how to customize the content of a Notebook tab label but really is a kickstart to any plausible gui arrangement.
With a simple example, I am going to illustrated how to build a ListStore TreeView in pygtk (python's gtk binding).
Building a standard ListStore in pygtk is pretty straightforward, however, it can get a bit more difficult to set up a custom TreeView where the rows and columns that are displayed can have different colors.
This tutorial will show how-to create and set up a TreeView, its TreeViewColumn and finally, the CellRenderer.
python-vte bindings allow you to embed a simplistic virtual terminal in any of your GTK apps real easy.
This tutorial will show how you can add a terminal to a widget in less than 30 lines, 4 lines only being necessary to set a the terminal session.
