Unreal Engine 4.x Scripting with C++ Cookbook - Second Edition

Adding Slate Widgets to the screen

The previous recipe used the FCanvas API to draw to the screen. However, FCanvas suffers from a number of limitations, for example, animations are difficult to implement, and drawing graphics on the screen involves creating textures or materials. FCanvas also doesn't implement anything in the way of widgets or window controls, making data entry or other forms of user input more complex than necessary. This recipe will show you how to begin creating HUD elements on-screen using Slate, which provides a number of built-in controls.
