OSDmenu 1.62 scrolling bug?

[gofti]

Hi,

I have the following menu ini setup (it's generated automatically by a custom Lua script). When I scroll beyond the Smallville (Oct 1) entry, it immediately jumps me back to Buffy Vampire Slayer (Nov 12) and then I can proceed to scroll down as usual. When scroll back in the up direction, I get to Alias (Oct 13) and it jumps me back down to Buffy (Nov 5).

This looks to be a simple scrolling bug, can this be fixed please? It's pretty irritating when scrolling through the menu.

Additionally, as a feature request, can the OSD be made double-buffered during movement? The flickering is driving my eyes nuts.

Thanks.

(P.S. the occurence of this bug appears to be related to the value of itemsperscreen, a higher number requires more items to scroll off the screen before exhibiting itself and vice versa.)

did you think of submenues?

[gofti]

Using submenus isn't a solution. It's just a poor workaround.

It should be a trivial fix.

My schedule is pretty busy at the moment but I will take a look when I get chance.

I *think* I've found/fixed the bug. There appeared to be two lines of code that had one specific function - to screw up the scrolling at certain points...Hmmm, a lesson to be learnt there - Always comment your code :wink:

Since I can't see any reason for those two lines to be there I need people to test the new version for me to see if it's introduced any other bugs in the scrolling.
I don't have access to an FTP server at the moment so please PM me your email address and I will send you a copy (93kb).



PS. I see your point with flickering and will try and implement doublebuffering in a future release.

Woohoo! Awesome, Matt! The scrolling works again, and the flickering is gone. My eyes are happy.

Thanks for fixing this so quickly.

Hello Matt,

It's great that the flickering within the menu is removed.

But I believe there is a new little bug which was not in version 1.62a.
:(
When I open a complete new ini-file, there is a very short flicker
in background over the whole size of the menu. It's only when I display
the menu ( the ini file ) for the first time.
I have a relative old vga ( matrox mill II ) in my Win98 computer.
A newer vga is much quicker and perhaps you don't recognize
this short flicker. ( I'm not sure )

I temporarly switched back to version 1.62a and the switching between
different ini-files was OK again.
Perhaps it has something to do with the new buffering.

If you have a little time in this X-mas shopping time, perhaps you
can have a look to OSDMenu ? :wink:
