A better practice is to forward-declare the UTextRenderComponent in your header, and then include the TextRenderComponent header in your .cpp file. (Some infoabout forward declarations) Unreal's build tool provides a convenient way to do this using the class keyword. ...
Forward-declared types need to be declared within their respective namespace. If you don't do this, you will get link errors. If you declare a lot of classes or types within a namespace, it can be difficult to use those types in other global-scoped classes (for example, function sig...
36 Using Forward Declarations If we #include in a .h file we create a “chain” Any .h file that includes us will in-turn include This can be hard to keep track of To simply use a type, we can “forward declare” Simply put class ClassName; under the includes ...

Mouse events don't require focus and they are propagated to the widgets under the cursor until one of the widgets handles the event. The Coherent UI Input Forward widget is generally on the top of the viewport so it can process mouse events first. The processing in the widget works as...

When you declare a class member as const, it means that the member cannot be modified once the object is created. However, there are scenarios where you may want to allow certain members to be modified even in a const object. This is where the mutable keyword comes into play. By using ...
