Widget Designer (Team)

Widgets are classes that represent individual menus or on-screen elements. You can define them in the Content Browser and build them in UMG, which has both a WYSIWYG (What You See Is What You Get) designer and a Blueprint graph.

Compiler

Section	Description
Allow Blueprint Tick	If disabled, widgets that these compiler options apply to will not be allowed to respond to the Event Tick event.
Allow Blueprint Paint	If disabled, widgets that these compiler options apply to will not be allowed to override the On Paint function.
Property Binding Rule	This setting controls whether to let the engine use property bindings in widgets. Using property bindings can have a large performance impact. You can choose from the following options: Allow: Allows the free use of property binding. Prevent: Prevents any new property bindings, but you can still edit widgets with property bindings. The buttons will be missing on all existing widgets that don't have bindings. Prevent and Warn: Prevents any new property bindings and gives a warning when the engine compiles any existing binding. Prevent and Error: Prevents any new property bindings and gives an error when the engine compiles any existing binding.
Rules	Custom widget compiler rule classes that you can write in C++. You can make these by extending the `UWidgetCompilerRule` class, which is in `WidgetCompilerRule.h`. These classes will have an `ExecuteRule` function that runs when you compile a widget blueprint. You can use this rules list to execute some custom code before the widget is finalized and compiled.
Directory Compiler Options	Allow Blueprint Tick, Allow Blueprint Paint, Property Binding Rule, and custom Rules, which you can set in specific project directories in a selective way.
