Wt

With github Wt 3.3.6-6-gbadb151, a WStackedWidget that uses fade animation can be set (restored) to an incorrect height at the end of the animation.

The attached test program demonstrates the issue by changing the index on a WStackedWidget to display a WContainerWidget with content that exceeds its natural size. With a non-animated transition, the height is set correctly and a scroller appears. With a fade animation, the height is initially set correctly (by the layout), but when the animation completes, the height is removed and the content extends beyond the window and is no longer scrollable.

A small patch is also attached for your review. The patch eliminates the height update (restore) when a fade-only animation completes. There are additional notes on the patch.
