OnDragRectangleChangedDeferredThreshold

If the computation time for a single call to OnDragRectangleChanged ever exceeds this threshold then future calls to this function (in the current drag sequence) will be deferred until the mouse button is released.

Choose your operating system:

Windows

macOS

Linux

Syntax

UPROPERTY()
double OnDragRectangleChangedDeferredThreshold

Remarks

If the computation time for a single call to OnDragRectangleChanged ever exceeds this threshold then future calls to this function (in the current drag sequence) will be deferred until the mouse button is released. This will improve the responsiveness of the UI. The default value is set so this optimization is never triggered, if you want it you can set this to a small value e.g., 1./60 (time elapsed by 1 frame at 60 fps)
