Question

我想将样式设置为组合框项目。试图使用CSS - 不工作。所以我尝试通过g_object_set直接设置属性。如果对象 gtk_list_store_new（1，G_TYPE_STRING）; 一切正常并且应用了样式。但是如果 gtk_list_store_new（2，G_TYPE_STRING，G_TYPE_STRING）; 应用程序粉碎了g_object_set。

代码：

  GError * error =0;
    GtkComboBox* cb = GTK_COMBO_BOX(widget);
     // GtkListStore *store = gtk_list_store_new(2, GDK_TYPE_PIXBUF, G_TYPE_STRING);
     GtkListStore *store = gtk_list_store_new(2, G_TYPE_STRING, G_TYPE_STRING);
    GtkTreeIter iter;

    gtk_list_store_insert_with_values(GTK_LIST_STORE(store), &iter, -1, 0, "Netherlands",1, "Netherlands", -1);
    gtk_list_store_insert_with_values(GTK_LIST_STORE(store), &iter, -1, 0, "Japan",1, "Netherlands", -1);
    gtk_combo_box_set_model(cb, GTK_LIST_STORE(store));

    GtkCellRendererText* cell = gtk_cell_renderer_text_new();
    gtk_cell_layout_pack_start(GTK_CELL_LAYOUT(cb), cell, TRUE);
    gtk_cell_layout_set_attributes(GTK_CELL_LAYOUT(cb), cell, "text", 0, NULL);

    GtkCellRendererText* cell2 = gtk_cell_renderer_text_new();
    gtk_cell_layout_pack_start(GTK_CELL_LAYOUT(cb), cell2, TRUE);
    gtk_cell_layout_set_attributes(GTK_CELL_LAYOUT(cb), cell2, "text",1, NULL);

    g_object_set(cell, "font", "Proxima Nova Rg 15");
    g_object_set(cell, "foreground", "#a5adbe");
    g_object_set(cell, "background", "#ffffff");
    g_object_unref(store);

堆栈追踪：

   strstr()
   ?? ()
   g_object_set_valist()
   g_object_set

代码在组合框的实现信号上执行

提前致谢！

当我在docs中找到 cell-background 属性时，很明显我使用了错误的属性。但它不会单独工作，你必须指定 cell-background-set＆＃34;我找到了here，我觉得。现在它完全适合我 - 背景，字体，所有设置都需要。

我的工作代码：

G_MODULE_EXPORT void on_countries_show(GtkWidget* widget, gpointer user_data) { GError * error =0; GtkComboBox* cb = GTK_COMBO_BOX(widget); GtkListStore *store = gtk_list_store_new(2, GDK_TYPE_PIXBUF, G_TYPE_STRING); GtkTreeIter iter; int h = gtk_widget_get_allocated_height(widget); h = 18; GdkPixbuf *nl = gdk_pixbuf_new_from_file_at_scale ("flags/NL.png", h, h, TRUE, &error); GdkPixbuf *jp = gdk_pixbuf_new_from_file_at_scale ("flags/JP.png", h, h, TRUE, &error); gtk_list_store_insert_with_values(GTK_LIST_STORE(store), &iter, -1, 0, nl, 1, "Netherlands", -1); gtk_list_store_insert_with_values(GTK_LIST_STORE(store), &iter, -1, 0, jp, 1, "Japan", -1); gtk_combo_box_set_model(cb, GTK_LIST_STORE(store)); GtkCellRenderer* pb = gtk_cell_renderer_pixbuf_new(); gtk_cell_layout_pack_start(GTK_CELL_LAYOUT(cb), pb, TRUE); gtk_cell_layout_set_attributes(GTK_CELL_LAYOUT(cb), pb, "pixbuf",0, NULL); GtkCellRenderer* cell = gtk_cell_renderer_text_new(); gtk_cell_layout_pack_start(GTK_CELL_LAYOUT(cb), cell, TRUE); gtk_cell_layout_set_attributes(GTK_CELL_LAYOUT(cb), cell, "text", 1, NULL); g_object_set(pb, "cell-background", "white", "cell-background-set", TRUE, NULL); g_object_set(cell, "font", "Proxima Nova Rg 15", "background", "white", "foreground", "#a5adbe", "cell-background-set", TRUE, NULL); g_object_unref(store); }

如果有人像我一样被困 - 欢迎你; - ）

如果定义了多个列，GtkCellRenderer g_object_set会崩溃
