从GTK消息对话框复制文本

我最后做的是在对话框中添加一个消息处理程序来捕获Keyboard up命令。

当它被触发时,我检查了CTRL-C组合键并将文本放到剪贴板上。

在gtk\u message\u dialog\u new()之后,通过对话框调用\u set\u lables\u selectable()

static void _set_label_selectable(gpointer data, gpointer user_data)
{
    GtkWidget *widget = GTK_WIDGET(data);

    if (GTK_IS_LABEL(widget))
    {
        gtk_label_set_selectable(GTK_LABEL(widget), TRUE);
    }
}

static void _set_lables_selectable(GtkWidget *dialog)
{
    GtkWidget *area = gtk_message_dialog_get_message_area(
        GTK_MESSAGE_DIALOG(dialog));
    GtkContainer *box = (GtkContainer *) area;

    GList *children = gtk_container_get_children(box);
    g_list_foreach(children, _set_label_selectable, NULL);
    g_list_free(children);
}

GtkWidget *dialog =  gtk_message_dialog_new(opgU_window,
GTK_DIALOG_DESTROY_WITH_PARENT,
GTK_MESSAGE_QUESTION,
GTK_BUTTONS_YES_NO,
"%s", mbuf);

_set_lables_selectable(dialog);
