我正在使用一个包含2列的表格的简单对话框，其中一列是复选框。我添加了一个GtkCellRendererToggle，但那个不可点击。我添加了一个永远不会调用的onToggle函数。 单元格渲染器是可激活的，我已经添加了一个调用来在C代码中第二次激活它以保证安全，但没有任何帮助。我究竟做错了什么？ 这是代码：
void
on_button_delete_files_click (GtkTreeSelection * widget, gpointer user_data)
{
GtkDialog * dialog = NULL;
GtkWidget * file_choser;
char * msg = NULL;
GtkListStore * liststore = NULL;
GtkTreeIter iter;
GDir * dir = NULL;
char * filename = NULL;
if (!builder_delete_files_dialog) {
GError * error = NULL;
builder_delete_files_dialog = gtk_builder_new ();
if (!gtk_builder_add_from_file (builder_delete_files_dialog, "deletedlg.glade", &error)) {
g_warning ("%s", error->message);
g_free (error);
exit (1);
}
}
//
// Get list store
//
liststore = GTK_LIST_STORE (gtk_builder_get_object (builder_delete_files_dialog, "podcast_file_liststore"));
//gtk_list_store_clear (liststore);
//
// Add all files
//
dir = g_dir_open (download_directory, 0, NULL);
if (NULL == dir) {
}
while (NULL != (filename = g_dir_read_name (dir))) {
if (NULL == g_strrstr (filename, ".mp3"))
continue;
gtk_list_store_append(liststore, &iter);
gtk_list_store_set (liststore, &iter,
TO_BE_DELETED, FALSE,
FILENAME, filename,
-1);
}
//
// nice try since stuff is not activatable
//
GtkCellRendererToggle * toggle = GTK_CELL_RENDERER_TOGGLE(gtk_builder_get_object (builder_delete_files_dialog, "cellrenderertoggle1"));
gtk_cell_renderer_toggle_set_activatable (toggle, TRUE);
dialog = GTK_WIDGET(gtk_builder_get_object (builder_delete_files_dialog, "dialog_delete_files"));
int rc = gtk_dialog_run (GTK_DIALOG(dialog));
switch (rc) {
case GTK_RESPONSE_OK:
case GTK_RESPONSE_CANCEL:
default:
break;
}
gtk_widget_hide (dialog);
__error:
FREE_POINTER(g_dir_close, dir);
}
void on_toggle_renderer_click (GtkCellRendererToggle * cell, char * tree_path, gpointer data)
{
g_print ("=====> Dingens clicked !!! <=====\n");
GtkTreeModel *model = (GtkTreeModel *)data;
GtkTreeIter iter;
GtkTreePath *path = gtk_tree_path_new_from_string (tree_path);
gboolean fixed;
/* get toggled iter */
gtk_tree_model_get_iter (model, &iter, path);
gtk_tree_model_get (model, &iter, TO_BE_DELETED, &fixed, -1);
/* do something with the value */
fixed ^= 1;
/* set new value */
gtk_list_store_set (GTK_LIST_STORE (model), &iter, TO_BE_DELETED, fixed, -1);
/* clean up */
gtk_tree_path_free (path);
}

再次：单击复选框时未调用onToggle-Event处理程序。这让我觉得单元格在某种程度上不活跃。
非常感谢每一个提示。 电贺 启

我通过使GtkCellRendererToggle'可激活'来实现它 - 即添加值为True的'activatable'属性。 - alexmurray

我在搜索如何切换GtkTreeView中的复选框时发现了这个问题。 对于同一条船上的用户，在渲染的树视图中单击复选框不会自动切换该框，但会发出“已切换”信号。 将此信号连接到回调函数，并在该函数中执行切换行时应执行的所有功能。
