Making widgets disabled/deactivated/inactive/insensitive

[chronoluminaire]

Hello. I know that for Buttons (or ui.buttons), you can make the button look "inactive" and be insensitive to mouse/keyboard actions by giving it a "clicked" parameter of None.

My question is, is there a way to do this for other widgets? The specific case I want is scrollbars, but it'd also be useful to be able to do it to other items.

In fact, as a feature request for a future version of Ren'Py, it'd be great if all focusable widgets had an "active" parameter, default True, that controls whether they use their "inactive" style or not and whether they respond to mouse/keyboard actions or not.

IIRC, sliders get to be inactive when their adjustment doesn't do anything interesting. I don't think the insensitive style for a bar differs from the idle style, however. (At least in the default themes.)

That's fine, I don't actually mind about making it look different - I just want to prevent the user from scrolling them on certain occasions (when I want to centre the viewport on something important happening). Can I keep the existing scroll position while modifying the adjustment to make it "not do anything interesting"? Is there any sensible way to do that, or will I have to override the change() method on the adjustment?

Thanks!

IIRC, if you create an adjustment without a change method, it should not be changable. (This may have been broken in 6.5.)
