Comment跟ToolTip不同，后者是用户鼠标悬停上的提示，前者只是简单的代码中的注释的记录。但是一般我们在代码里写上的注释，会自动也加到ToolTip 上，因此我们往往也会看到UI界面上的提示。
|
|||
|
|
|
|||
|
|
但如果不想要ToolTip，想只有Comment，则也可以自己手动在meta里添加。
|
|||
|
|
|
|||
|
|
## 测试代码：
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
//(BlueprintType = true, Comment = //This is a comment on class, IncludePath = Property/Development/MyProperty_Development.h, ModuleRelativePath = Property/Development/MyProperty_Development.h, ToolTip = This is a comment on class)
|
|||
|
|
|
|||
|
|
//This is a comment on class
|
|||
|
|
UCLASS(BlueprintType)
|
|||
|
|
class INSIDER_API UMyProperty_Development :public UObject
|
|||
|
|
{
|
|||
|
|
GENERATED_BODY()
|
|||
|
|
public:
|
|||
|
|
//(Comment = //This is a comment on function, ModuleRelativePath = Property/Development/MyProperty_Development.h, ToolTip = This is a comment on function)
|
|||
|
|
|
|||
|
|
//This is a comment on function
|
|||
|
|
UFUNCTION(BlueprintCallable)
|
|||
|
|
int32 MyFunc(FString str){return 0;}
|
|||
|
|
|
|||
|
|
// (Category = MyProperty_Development, Comment = //This is a comment on property, ModuleRelativePath = Property/Development/MyProperty_Development.h, ToolTip = This is a comment on property)
|
|||
|
|
|
|||
|
|
//This is a comment on property
|
|||
|
|
UPROPERTY(EditAnywhere, BlueprintReadWrite)
|
|||
|
|
int32 MyProperty = 123;
|
|||
|
|
|
|||
|
|
//(Category = MyProperty_Development, Comment = This is my other property., ModuleRelativePath = Property/Development/MyProperty_Development.h)
|
|||
|
|
|
|||
|
|
UPROPERTY(EditAnywhere, BlueprintReadWrite,meta=(Comment="This is my other property."))
|
|||
|
|
int32 MyProperty_WithComment = 123;
|
|||
|
|
};
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## 测试结果：
|
|||
|
|
|
|||
|
|
MyProperty_WithComment是单独只加的Comment，就没有了鼠标悬停效果。
