Android Question BBScrollingLabel keeps previous value when new text is empty

[wimpie3]

I'm currently using

[B4X] BBScrollingLabel - rich text scrolling label

(this is an animated gif, it is is much smoother in real usage) BBScrollingLabel is similar to XUI Views ScrollingLabel, however it is based on BCTextEngine and can therefore display formatted text. It is cross platform. Usage instructions: - Download the b4xlib and put it in the B4X...

www.b4x.com

Setting a text in the scrolling label is easy:

BBScrollingLabel1.Text="[color=#ffffff][TextSize=28]" & stringtoshow & "[/textsize][/color]"

However, when I want to clear the label:

stringtoshow =""
BBScrollingLabel1.Text="[color=#ffffff][TextSize=28]" & stringtoshow & "[/textsize][/color]"

the previous label is still shown. So it seems that when there is no text to draw, the previous scrolling text isn't cleared. How can I solve this issue?

You should use smart strings with BCTextEngine:

BBScrollingLabel1.Text=$"[color=#ffffff][TextSize=28]${stringtoshow}[/textsize][/color]"$

This issue is fixed in v1.03.
