Python的GUI程序设计

一、实验目的：

1、熟练掌握Frame窗体的使用；
2、熟练掌握基本控件的用法。
二、实验内容：
1、编写代码实现当改变窗体位置和大小时，除在文本框中显示信息外，还需在状态栏动态变化显示“窗体大小：XXX，XXX；窗体位置：XXX，XXX”。当鼠标在窗体内移动时，文本框会实时显示鼠标的当前坐标，当鼠标移动到窗体之外时，文本框的内容不再变化。程序运行效果如图1所示。

图1 程序运行效果

2、编写代码创建菜单，当在文本框中输入一个数字，点击菜单项，然后在另一个文本框显示是否为素数。是则显示yes,否则显示No，程序运行效果如图2所示。

图2 程序运行效果

3、编写代码单选按钮实现性别选择，复选框实现兴趣爱好的选择，并输入文本框中要求的用户名和密码，单击OK按钮会弹出消息框提示输入和选择的内容，单击Cancel按钮自动清除用户的输入，并默认单选按钮性别Male为选中状态。界面效果如图3所示。
