Hi All,
Can some one please clarify what does attributes mean ? The below code seems to confuse me what does it mean by foreground taking the value of COLOR_COLUMN (which is 1) enum { TEXT_COLUMN, COLOR_COLUMN, N_COLUMNS }; ... { GtkTreeViewColumn *column; GtkCellRenderer *renderer = gtk_cell_renderer_text_new (); column = gtk_tree_view_column_new_with_attributes ("Title", renderer, "text", TEXT_COLUMN, "foreground", COLOR_COLUMN, NULL); } -- Regards, ~Sid~ I have never met a man so ignorant that i couldn't learn something from him _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@... http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list |

With gtk_tree_view_column_new_with_attributes you can connect cell attributes to columns of the underlying model. For example, given the following model: "this is an example" | #red "hello, world!" | #green the code below connects the "text" attribute to the first model column (TEXT_COLUMN) and the "foreground" attribute to the second one (COLOR_COLUMN) - note that these are not valid color values. The resulting tree view should look like this: Title ------------------- this is an example hello, world! The first row should be printed in red letters, the second one in green ones. > > The below code seems to confuse me > > what does it mean by foreground taking the value of COLOR_COLUMN (which is 1) > > enum { TEXT_COLUMN, COLOR_COLUMN, N_COLUMNS }; > ... > { > GtkTreeViewColumn *column; > GtkCellRenderer *renderer = gtk_cell_renderer_text_new (); > > column = gtk_tree_view_column_new_with_attributes ("Title", > renderer, > "text", TEXT_COLUMN, > "foreground", > COLOR_COLUMN, > NULL); > } _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@... http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list |
