CommonViewer provides a JFace TreeViewer subclass that may be suitable in standalone E4 applications. $model = new GtkListStore(Gtk::TYPE_STRING, Gtk::TYPE_STRING, Tree, Table, etc), plus your domain objects. GObject::TYPE_LONG, GObject::TYPE_DOUBLE) JFace viewers consist of an SWT widget (e.g. $model = new GtkListStore(GObject::TYPE_STRING, GObject::TYPE_STRING, $scrolled_win->set_policy( Gtk::POLICY_AUTOMATIC, Introduction ViewerColumn implementation for TreeViewer to enable column-specific label providers and editing support. $title->modify_fg(Gtk::STATE_NORMAL, GdkColor::parse("#0000ff")) Eclipse JFace TreeViewerColumn tutorial with examples Previous Next ViewerColumn implementation for TreeViewer to enable column-specific label providers and editing support. $title->modify_font(new PangoFontDescription("Times New Roman Italic 10")) Setting the Stage Because the TreeViewer uses domain objects to populate its Tree, we will create a simple model to be used throughout this article. $title = new GtkLabel("Set the background color of treeview column header") More information about JFace and SWT can be found in the Javadoc for, , and JFace viewers. $window->connect_simple('destroy', array('Gtk','main_quit')) The main difference is that the TreeViewer class requires a structured content provider.

Using viewers to display a tree The TreeViewer class provides viewer support for displaying trees.If you don't like this, then don't use this method. They said it's not right accessing into the internal data structures. I know there are some people that don't like this.However, by getting the pointer to the GtkButton that holds the treeview header, you can set the background color of that GtkButton, and hence the header.But at least for now, there is no method that allows you to do so directly. For those of you who have played with PHP-GTK2 for some time, you will know that setting the background of treeview header is not supported, yet.Suppose you would like to set the background color of the header of the Price column in the treeview as shown below: How to set the background color of the column header of a treeview?
