Overview

ULimenDraggableWidget is a subclass of UWidget designed to provide drag functionality. It supports two types: a brush and a custom user widget. The widget's appearance and behavior are configurable through properties such as WidgetType, CustomWidget, and WidgetBrush.

Functions

Return Type	Signature	Description
`TSharedRef<SWidget>`	RebuildWidget()	Constructs and returns the Slate widget for this UMG widget.
`void`	ReleaseSlateResources(const bool bReleaseChildren)	Releases any resources used by the Slate widget.
`FReply`	MouseDown(const FGeometry& InGeometry, const FPointerEvent& MouseEvent)	Handles mouse down events to capture and start dragging.
`FReply`	MouseUp(const FGeometry& InGeometry, const FPointerEvent& MouseEvent)	Handles mouse up events to release the mouse capture.
`FReply`	MouseMove(const FGeometry& InGeometry, const FPointerEvent& MouseEvent)	Handles mouse move events to update the widget's position during dragging.

Usage & Implementation Notes

The widget uses a SMouseDetector for detecting and handling mouse events.
When WidgetType is set to CustomWidget, an instance of the specified custom user widget is created and displayed.
The widget's position can be updated by capturing mouse movement and adjusting its render translation.
