Scrolling in Conditional Viewports?

(1/3) > >>

pwhodges:
Should scrolling be possible in conditional viewports? 

As far as I can see, it isn't (I simply changed a working viewport to conditional with no other change, and the scrolling stopped).  But I can see no statement anywhere that it either should or shouldn't work.

I've never had problems with scrolling in conditional viewports myself, so I suspect conditional viewports should work identically to regularly defined viewports, aside from only being displayed if the appropriate condition is met.  Perhaps you can post a snippet of the WPS code that isn't working the way it should?

linuxstb:
If a viewport is redrawn frequently, or the scrolling line(s) are redrawn frequently, then that resets the scrolling - so in effect this may be what you're seeing.

Posting your .wps file would be helpful.

OK, here you are.  It's for the H340, loosely based on unicatcher.  As most of my music is classical and untagged, I normally display the directory structure; but this version switches to tags when the hold switch is on.  This works, but there is no scrolling in the conditional viewports.

I wouldn't know for certain if this is what's causing your problems, but:

(edited to fit...)

I don't know exactly what that does visually, but that's a pretty short display time (one-tenth of a second).  I would suspect that would cause issues...

EDIT:  Especially since it's being done in the default viewport...  Does anyone know how a rapidly-switching image in the default viewport would affect the rest of the viewports drawn afterward..?
