UIDraggablePanel Scrollbar isVisible

[devomage]

Where/when is the best place to detect changes in this property?  Fails in both Awake/Start and takes a cycle or two in Update.  Is there possibly an event to subscribe to that i'm overlooking?

Appreciate the best solution.  Thanks!

1. public UIDraggablePanel mypanel;
2.  
3. Debug.Log(mypanel.verticalScrollBar.background.isVisible);
4. Debug.Log(mypanel.verticalScrollBar.foreground.isVisible);
5.

UIWidget.isVisible simply tells you if the widget's alpha is above zero, and the scrollable panel tweens the alpha of the scroll bar to make it fade in -- which is likely why you are seeing a delay.

What are you trying to do?

The size of my highlight sprite and a couple buttons are conditional if the scrollbar is visible.  I am using 2 different prefabs for the grid rows and disabling the 2 up/down scrollbar buttons.

Why not check UIScrollBar's barSize instead? It will be 1 if the window is able to fit everything, and non-1 if it can't.

The barSize never returns a value of "1".  See attached screenshot.

1. Debug.Log("Update = " + mypanel.verticalScrollBar.barSize);

Well in your case check for < 0.99 then
