ComboBox与图像GTK

Question

如何将图像添加到ComboBox？我想要文字和正确的图像？

我试图实现它,但它没有用^.^

需要任何建议

Answer 1

首先,您需要一个模型来存储项目(文本和图像).

enum {COL_TEXT, COL_ICON, NUM_COLS};

GtkListStore *store = gtk_list_store_new( 2, G_TYPE_STRING, GDK_TYPE_PIXBUF );

/* add some data */
GtkTreeIter iter;
gtk_list_store_append(store, &iter);
gtk_list_store_set( store, &iter, COL_TEXT, some_text, COL_ICON, some_pixbuf, -1 );

接下来,您创建GtkComboBox(或者GtkComboBoxEntry您可以跳过创建文本单元格渲染器).

// GtkComboBoxEntry *combo = gtk_combo_box_entry_new_with_model( GTK_TREE_MODEL(store), COL_TEXT );
GtkComboBox *combo = gtk_combo_box_new_with_model( GTK_TREE_MODEL(store) );

GtkCellRenderer *renderer;

/* text cell */
renderer = gtk_cell_renderer_text_new();
gtk_cell_layout_pack_start( GTK_CELL_LAYOUT(combo), renderer, TRUE );
gtk_cell_layout_set_attributes( GTK_CELL_LAYOUT(combo), renderer, "text", COL_TEXT, NULL );

/* icon cell */
renderer = gtk_cell_renderer_pixbuf_new();
gtk_cell_layout_pack_start( GTK_CELL_LAYOUT(combo), renderer, FALSE );
gtk_cell_layout_set_attributes( GTK_CELL_LAYOUT(combo), renderer, "pixbuf", COL_ICON, NULL );
