Hey Experts,

And after clicking on a Button the state changes zu activated so the Buttons look so:

if i focus one not hover and click on it till i click on a Button it looks like this:

so what I want I wann to set the Button who is pressed to the white colour and the Button which i activated but got status pressed="false"

should look like "Reportanzeigen" in screen Above.

So I don't know which stat off .sapMToggleBtn it is?.
