Hello all

I wanted to have an Splitter with transparent background.
The Splitter is child of a StaticRect.

So in the parent constructor:

Parent::Parent() {
	splitter.Transparent();
	Background(Null);
}

The splitter looks transparent, but when resizing the splitter middle frame, the splitter gets black:

index.php?t=getfile&id=2089&private=0

Do you know how to solve it ?

Best regards

It might be U++ bug. Can you create a simple testcase please?

Hello all

It is solved.

The trick is to follow these rules:

- To define a StaticRect as transparent it is needed to do both:

	Transparent();
	Background(Null);

- To define a Splitter as transparent it is needed to do this:

	Transparent();

Following these rules it is possible to stack some transparent Splitter and StaticRect.
