Button Transparancy

I’m using the Jucer for some mock-ups and found the Text Buttons weird with the default look and feel.
Even when Alpha is set to FF (non-transparent) the button is transparent. This is unintuitive and especially a problem with strong background colors because it’s hard to see button color differences.
Is this normal?
Is there an easy way to change that?

And a bit unrelated: Can the button be turned “on” in the Jucer so I can see what it would look like when active?

TextButtons are drawn this way and they’re always a bit transparent. If you want “other” buttons you need to make them yourself, The Juce allows you to do that.
