Question

现在有一个窗口,是ShowDialog出来的顶级窗口,现在想在这个窗口的按纽单击的时候弹出一副"正在处理,请稍等的动画",在事件处理结束之后自动关闭.1.最好不用进度条控件
2.我自己的做法:在单击按纽之后兴建一个线程,在线程中弹出一个Form,Form里面加载picturebox.
   这个方法一般时可以,只是在当前窗口为showdialog窗口的时候,新线程的动画窗口就被showdialog窗口覆盖了,有没有办法让动画窗口显示在showDialog窗口的上方不被覆盖?

Answer 1

在顶级窗口中的按钮事件中添加：
Form frm = new Form();
frm.Owner=this;
就行了

Answer 2

此方法不行,Form能出来,可是我在Form上动态加载的控件要到按纽事件执行完之后才会显示出来,我要窗口一出来就有控件

Answer 3

加load事件有什么用?单击按纽不走load事件的,我做的不是WEB的

Answer 4

你说怎么设计?问题的关键是能不能把ShowDialog的层次下降一个

你不是有两个对话框吗？
一个是“ShowDialog出来的顶级窗口”，在点按钮的时候，显示“动画窗口”，是不是这样？
在顶级窗口中的按钮事件中添加：
动画窗口frm = new 动画窗口();
frm.Owner=this;
frm.Show();

Answer 7

你只要设置
顶级窗口.Owner = 顶级窗口;
就OK

Answer 8

将showdialog改用form不就得了～

Answer 9

写错
动画窗口.Owner = 顶级窗口;
就OK

Answer 10

在t.Start();后面阻塞主线程，等t线程执行完再释放主线程；
用一个bool变量也可以做到

Answer 13

temp.Show();改成 temp.ShowDialog();

Answer 14

把图片再ShowDialog()出来不行么？

Answer 15

你应该在按钮的Mouse_down事件里写处理吧
