Re: tree_view

[André Pedralho <apedralho gmail com>]

It is not an easy task to create and begin to populate a tree view.
You have to set a lot of others widgets, but I'll show you a short
code to help you.

GtkWidget *treeStore, *treeView
GtkTreeViewColumn *column1, *column2...;
GtkCellRenderer *renderer1,*renderer2...;

treeStore = GTK_TREE_MODEL(gtk_tree_store_new(2,G_TYPE_STRING,G_TYPE_STRING));

treeView =
gtk_tree_view_new_with_model(GTK_TREE_MODEL(treeStore));

/* optional settings */
gtk_tree_view_set_headers_visible(GTK_TREE_VIEW (treeView), TRUE);
gtk_tree_view_set_headers_clickable (GTK_TREE_VIEW (treeView), TRUE);
gtk_tree_view_set_reorderable(GTK_TREE_VIEW (treeView), TRUE);
gtk_tree_view_set_rules_hint(GTK_TREE_VIEW (treeView), TRUE);

gtk_widget_show(treeView);

/* setup the renderer */
renderer1 = gtk_cell_renderer_text_new();
gtk_cell_renderer_set_fixed_size (renderer1,100,-1);
column1 = gtk_tree_view_column_new_with_attributes("Name", renderer1,
"text", 0, NULL);
gtk_tree_view_column_set_resizable (column1, TRUE);

gtk_tree_view_append_column(GTK_TREE_VIEW(bwin->treev),
                                column1);
gtk_tree_view_set_expander_column(GTK_TREE_VIEW(bwin->treev),column1);

/* you could make the same for the others columns and renderer or just
use the same renderer for all of them */

gchar *text1= "any text";
GtkTreeIter *newIter, *parentIter;

/* now you can append your item. if newIter is NULL, it will be the
root of the tree */
gtk_tree_store_append(GTK_TREE_STORE(treeStore),newIter,parentIter);
gtk_tree_store_set(GTK_TREE_STORE(treeStore), newIter, 0,text1, -1);

So... it is just a begining... Look at the api and the following tutorial:

I hope I could help you!
