如何以编程方式单击复选框？ [英] How to click a checkbox programmatically?

问题描述

我可以自己调用chkMyCheckBox_CheckedChanged（），但这是对点击的响应，而不是点击本身。虽然这对于一个

按钮是好的，但它对于一个复选框来说是不够的，因为复选框应该更新它的位置。
更新它的位置。当然，我可以将复选框设置为

新值（需要反转其当前值）。


有更好的方法吗？


（更一般地说，我的问题是：我有一些用于某些设置的GUI，而且我想要程序以编程方式设置其中一些，在启动时。

GUI应该反映所做出的决定。如果用户加载程序，最终结果应为=

，然后转到设置，然后单击

打开和关闭一些选项。）

I could call chkMyCheckBox_CheckedChanged() myself, but this is the
response to the click, not the click itself. While this is fine for a
button, it is insufficent for a check box, as the check box should
update its position. Of course, I could just set the check box to the
new value (which required inverting its current value).

Is there a better way?

(More generally, my issue is: I have a GUI for some settings, and I
want the program to set some of them programatically, at start up.
The GUI should reflect the decisions made. The end result should = as
if the user loaded the program, and went to the settings, and clicked
some options on and off.)

就是这样。


chkMyCheckBox.Value = true; ''true = checked false =未选中。


您最有可能需要全局OnStatup-flag = true，因为设置

chkbox。 Value = true将触发chkbox_Changed事件。检查

更改事件中的Onstart-flag = true允许您在应用启动期间绕过执行代码

。然后在app

启动后设置flag = false。

That would be this.

chkMyCheckBox.Value = true; '' true = checked false = unchecked.

You''ll most likely need a global OnStatup-flag = true as well, as setting
chkbox.Value = true is going to fire the chkbox_Changed event. Checking the
Onstart-flag = true in the Change Event allows you to bypass executing code
in the event during app start-up. Then you set the flag = false after app
start-up.

这是一个坏主意。你不应该直接打电话给事件。

This is a bad idea. You should never call an event directly.

OP想要复选框更改事件。

The OP wants the checkbox change event to fire.
