如何使应用程序响应Windows而不是用户在漫长的过程中？ [英] How to make app responsive to windows but not to user during long process?

问题描述

我想让我的应用程序重新绘制并在长期运行过程中显示等待光标，但实际上并未响应用户事件。什么是

实现这个的最好方法？


如果我只是将流程放在另一个线程上，用户可以继续

与表单互动。对于我自己的代码，我可以在所有

事件处理程序中有一个标志，但是控件内的交互怎么办（例如，在树视图中展开/折叠树节点）。如果我更改Enabled

属性，则会影响控件的视觉外观，我不想这样做。


有什么建议/例子吗？


谢谢，

I want to make my app repaint and show a wait cursor during a long
running process but not actually respond to user events. What''s the
best way to implement this?

If I just put the process on another thread, the user can continue to
interact with the form. For my own code, I can have a flag in all
event handlers, but what about interaction within a control (i.e.,
expand/collapse tree nodes in treeview). If I change the Enabled
property, that affects the visual appearance of the controls, which I
don''t want to do.

Any suggestions/examples?

Thanks,

Sam

推荐答案

Samual，


在早期关于你这样的问题的情况下，我曾经给出了

想法来设置一个小组（在表单上保存所有控件）并且设置为

要启用的面板是错误的。


这可能是你正在寻找的东西。关闭并最小化

框仍然有效，因此用户可以最小化调整大小并移动

表格。


我希望这有帮助

Samual,

In an earlier situation about such a question as yours I once have given the
idea to set a panel (that holds all controls) on a form and too set that
panel to enable is false.

Is that maybe somehing you are looking for as well. The close and minimize
box is than still working so the user can minimize resize and move that
form.

I hope this helps

谢谢，但是仍然影响控件的视觉显示和

i想要避免（等待光标表示他们不能点击，

不需要禁用外观同样）。

Thanks, but that still affects the visual display of the controls and
i want to avoid that (the wait cursor indicates that they can''t click,
don''t need disabled appearance as well).

Samuel，


在这种情况下，它们仍然在那里，但有点阴影，我认为

等待光标这是特别好的。


但是只是我的想法。


Cor

Samuel,

In that case they are still there, however a little bit shadowed, I think
this is extra good with a wait cursor.

However just my idea.
