Re: Is it possible having different GtkAdjustment values in GtkTreeView

["Tadej BorovÅak" <tadeboro gmail com>]

Hi.

I've created a simple app that demonstrates some G(TK)_TYPE macro magic;)

--------------
#include <gtk/gtk.h>

enum
{
    MODEL_COL,
    NO_COLS
};

static GtkTreeModel *
create_and_fill_model (void)
{
    GtkListStore  *store;
    GtkListStore  *model;
    GtkTreeIter    iter;

    model = gtk_list_store_new( 1, G_TYPE_STRING );
    gtk_list_store_append( model, &iter );
    gtk_list_store_set( model, &iter, 0, "String1", -1 );
    gtk_list_store_append( model, &iter );
    gtk_list_store_set( model, &iter, 0, "String2", -1 );
    gtk_list_store_append( model, &iter );
    gtk_list_store_set( model, &iter, 0, "String3", -1 );
    gtk_list_store_append( model, &iter );
    gtk_list_store_set( model, &iter, 0, "String3", -1 );
    gtk_list_store_append( model, &iter );
    gtk_list_store_set( model, &iter, 0, "String4", -1 );
    gtk_list_store_append( model, &iter );
    gtk_list_store_set( model, &iter, 0, "String5", -1 );

    store = gtk_list_store_new( NO_COLS, GTK_TYPE_TREE_MODEL );
    gtk_list_store_append( store, &iter );
    gtk_list_store_set( store, &iter, MODEL_COL, GTK_TREE_MODEL( model ), -1 );

    return GTK_TREE_MODEL(store);
}

int
main( int    argc,
      char **argv )
{
    GtkWidget         *window;
    GtkWidget         *pop_window;
    GtkWidget         *treeview;
    GtkWidget         *label;
    GtkTreeModel      *model;
    GtkTreeIter        parent;
    GtkTreeIter        child;
    GtkCellRenderer   *renderer;
    GtkTreeViewColumn *col;
    GtkTreeSelection  *sel;

    gtk_init( &argc, &argv );

    window = gtk_window_new( GTK_WINDOW_TOPLEVEL );
    g_signal_connect( G_OBJECT( window ), "destroy",
                      G_CALLBACK( gtk_main_quit ), NULL );

    model = create_and_fill_model();
    treeview = gtk_tree_view_new_with_model( GTK_TREE_MODEL( model ) );
    g_object_unref( G_OBJECT( model ) );

    /*col1*/
    col = gtk_tree_view_column_new();
    renderer = gtk_cell_renderer_combo_new();
    g_object_set( G_OBJECT( renderer ), "editable", TRUE, NULL );
    g_object_set( G_OBJECT( renderer ), "text_column", 0, NULL );
    gtk_tree_view_column_pack_start(col, renderer, TRUE);
    gtk_tree_view_column_set_attributes(col, renderer, "model",
MODEL_COL, NULL);

    gtk_tree_view_append_column(GTK_TREE_VIEW(treeview), col);

    gtk_tree_view_expand_all( GTK_TREE_VIEW( treeview ) );
    gtk_container_add( GTK_CONTAINER( window ), treeview );
    gtk_widget_show_all( window );

    gtk_main();

    return( 0);
}
