Handle Array Structure in php gtk

In this post, we display a tree structure from array in php gtk, for do this please follow below points:

1.) Sets up the treestore to store the data. Here it sets three fields. The first one is integer that stores the id. The second and third are strings.

2.) Creates a GtkTreeview. It is here that you bind the model to the treeview.

3.) Sets up the treeview columns.

4.) Loops through the data list and appends the data one by by to the tree structure. Note that $nodes stores the GtkTreeiter of each node. You can view this as a pointer to the node.

Change Background color of GtkWindow in PHP GTK

Many People often want to change background color of GtkWindow in PHP GTK. Here is a simple example.

In below example, we use  void modify_bg( GtkStateType state , GdkColor color ); for set background color of GtkWindow. According to PHP-GTK 2 Manual GtkStateType indicates the current state of a widget; the state determines how the widget is drawn. The GtkStateType enumeration is also used to identify different colors in a GtkStyle for drawing, so states can be used for subparts of a widget as well as entire widgets.
