下面来记录一下Qt中的形形色色的Dialg。。。。
直接给出PySide自带的example,因为我觉得我的改写也只是“依葫芦画瓢”。。。放心，Qt是开源的，真伟大。。

下面给出效果图：
（1）整体效果图
（2）下面依次展示出各种形式的对话框：
（获取的是整数值）
（获取的Double型的数据）
（有下拉列表选择的对话框）
（可以获取用户输入的对话框）
（改变颜色的对话框）
（感觉好大的一个对话框啊，但是他是内置好的，当然如果界面你不喜欢的话，调出他的库函数，你再重写即可，要是偷懒的话，那就直接调用呗）
（获取文件夹的路径）
（获取文件路径）
（样子好像和上一张一样但是，它可以获取多个文件的路径）
（获取保存文件的路径，如文件已存在则覆盖，如不存在则新建）
（类似于警报了，还会有声音）
（信息提示）
（注意图标的不同，而且这张的几个按钮是将默认按钮替换为其他按钮啦）
（这几张其实都差不多，注意醒目的logo就好）
