C ++ CheckBox检查常量 [英] C++ CheckBox Checked constant

问题描述

你好，

这个问题看似微不足道，但却使我头疼不已.我的自定义控件中有4个复选框，用于控制要在图形上显示的子集.当这些CheckBoxes''Checked属性中的任何一个发生更改时，它将触发事件处理程序.

问题是无论CheckBox的初始值是多少，无论事件运行了多少次或UI显示了什么，选中的状态始终返回true或false.这是示例行:

Hello,

This problem seems so trivial, yet it is causing me a big headache. I have 4 checkboxes in my custom control, which I use to control which subsets to show on a graph. When any of these CheckBoxes'' Checked property is changed, it fires an event handler.

The problem is that the checked state always returns true, or false, whatever the CheckBox''s initial value is, no matter how many times the event is run or what the UI shows. Here is a sample line:

int i = System::Convert::ToInt16(vccCheck->Checked);

谢谢您的帮助.

Any help would be appreciated, thanks.
