I try to implement tree like in windows explorer using gtkmm3.
My problem is that to add icon I add a column for it, so it look strange 1 : * The tree triangle and dot line is on the left * All text label is aligned on there row on the right. * And icon are floating between us aligned on the left => See attached image for more details...
My goal it to have text not aligned on a row but following the icon with a fixed width.
Thanks for your help,
Self-service : solution is here : https://developer.gnome.org/gtkmm-tutorial/stable/sec-treeview.html.en - 9.2.3. More than one Model Column per View Column => Who said that there's no documentation...
1 - Create a Gtk::TreeView::Column
2 - Add column with icon
* fct : column->pack_start ( put your column id here, false ); <= false (no padding)
* Model : Gtk::TreeModelColumn
3 - Add column with text
* fct : column->pack_start ( put your column id here, true ); <= true (padding)
* Model : Gtk::TreeModelColumn
4 - Add colun to tree : tree->append_column ( column)
5 - set line icon and text
* row[column text id] = "Billy Bob";
* row[column icon id ] = Gdk::Pixbuf::create_from_file ( "png path in my case" );
Warning icon size is 1:1 to adjust size you need to add more code. In my case i use svg so i can build the pix with the right size...
Tips : To hide header : tree->set_headers_visible ( false );
