我的自定义控件在自定义标签的“锚点属性”中设置我想要的值。
将Serializable设置为Visible我获取为运行时生成的代码,我没有使用类型Content,但设计器中的控件具有给出Label的Anchor值,(Left和Top),因此,要在设计器中获得正确的行为,需要手动(非)更改Anchor属性。
我真的不想写一个设计师来完成这项工作(以我的进步速度,我认为这不是明智的!),是否有更简单的方法?
public:
[DesignerSerializationVisibility(DesignerSerializationVisibility::Visible)]
virtual property System::Windows::Forms::AnchorStyles Anchor
{
System::Windows::Forms::AnchorStyles get() override
{
return static_cast<System::Windows::Forms::AnchorStyles
((System::Windows::Forms::AnchorStyles::Top
| System::Windows::Forms::AnchorStyles::Left)
| System::Windows::Forms::AnchorStyles::Right);;
}
void set(System::Windows::Forms::AnchorStyles x) override
{
__super::Anchor = static_cast<System::Windows::Forms::AnchorStyles
((System::Windows::Forms::AnchorStyles::Top
| System::Windows::Forms::AnchorStyles::Left)
| System::Windows::Forms::AnchorStyles::Right);
}
}

您正在硬编码属性值。因此,在构造函数中指定值,使其不可浏览,以便它不会显示在属性窗口中,并确保无法更改值并且不会序列化。像这样:
ref class MyControl : Control {
public:
MyControl() {
__super::Anchor = AnchorStyles::Top | AnchorStyles::Left | AnchorStyles::Right;
}
[Browsable(false), EditorBrowsable(EditorBrowsableState::Never)]
[DesignerSerializationVisibility(DesignerSerializationVisibility::Hidden)]
virtual property System::Windows::Forms::AnchorStyles Anchor {
AnchorStyles get() override {
return __super::Anchor;
}
void set(AnchorStyles) override {
// do nothing
}
}
};
