B4A Library ScratchView V1.5

:D

This wrap has more functionality as the wrapped lib was. The Original does only have a event when you reveal the hole object.... I thought it would be nice to have an additional event when you do your first scratch on one of the scratchitems.... The onScratching event was born :)
My example shows this

Very very nice, Manfred.
Scratching effect was applied to one of my first apps..eventually it could be re-tooled with your lib!

Great work Don ( as usual ;) ) +40
Look this 2 little demo:
In this first movie as i "touch" but i dont see Text in ( 0$, 1$ or 5$ ) o_O

if i write ScratchTextView1.Text i dont see this in code but i see in Design.
P.S. You forget in your demo donmanfred.png

I should "test" it (to know the differences); anyway, I did something like this... probably 2 years ago and... not for me :p

It was a "Gratta e Vinci" (Scratch and win)

This is just to say: "Unfortunately at the time there was not this library" ;)

"PercentageRevealed event" is feature very important for this library.
I missed this feature and told about in b4achatroom...

- I got a suggestion from @NJDude for a library which does have such a feature.
- I tried to make a wrap for it till i saw it does not work. But i copied the code from it which does the calculation and i extended this lib with the code from the other lib. It works!

V1.2 was born :D

@DonManfred Am aware that this thread is old but am kindly wanted to ask that PercentRevealed fixed on v1.5? It is not working for me here..
