How to clear the No Playing screen (WPS) backdrop?

[chrisjj]

... please?

I find this screen backdrop is not cleared by Clear Backdrop. The only setting I have found that does clear this screen's backdrop is While Playing Screen, rockbox_failsafe, but this makes also changes that are unwanted.

I'm using the Creative ZEN port, in beta.

Thanks.

you need to modify the wps file in .rockbox/wps/<theme name>.wps, delete the line which starts %X(<some filename>)

I'm going to step in here and disagree with the prior statement.

You should not have to edit anything at all.

The clear backdrop function most definitely should work, and manually editing the .wps file is a band-aid fix which completely avoids the issue.

Would it work? Certainly.

Should you or anyone else need to do this when there is a perfectly good function that's supposed to do this for you? Absolutely not.

OK, [Saint] thinks I may have misinterpreteed your question. Which theme are you using and which backdrop are you expecting it to clear which it doesnt?

What the "clear backdrop" setting *should* be doing is clear the backdrop specified in the config.cfg file (I think the line is just "backdrop: /path/to/image.bmp") Depending on the theme you are using this may not be the same one the WPS uses.

Indeed that's what I found and is confirmed by the manual at http://download.rockbox.org/daily/manual/rockbox-ipodcolor/rockbox-buildch13.html#x16-33600013.1.6. It says that backdrop is for File Browser and menus, though I take that to mean all non-skinnable pages.

Having said which, I think the 'clear all backdrops' behaviour described by [Saint] is (would be) a much better design choice.

Depending on the theme you are using this may not be the same one the WPS uses.

Surely clearing the browser/menus backdrop using Clear Backdrop as currently documented, should not clear the WPS backdrop even when they are the same backdrop.

thats not how the backdrops work.
If the .wps (or .fms etc) specify a backdrop image it is used, otherwise the config.cfg one is used, so if there is none specified in the config none will be shown

thats not how the backdrops work.

Then perhaps we're suffering variation. Because that is how the backdrops work on the Creative ZEN port (admittedly beta) I'm using.

If the .wps (or .fms etc) specify a backdrop image it is used, otherwise the config.cfg one is used

That's what I see.

so if there is none specified in the config none will be shown

I have to say (to my thinking), that does not follow from the above.

Also, that is not the program behaviour I see. What I see is that with .wps specifying a backdrop and (theme) config specifying none, the .wps-specified backdrop is shown on the WPS. As seems logical.

A note to anyone experimenting: After altering the current .cfg file over USB, reselecting it in Settings fails to engage the altered version until next boot. It is as if the .cfg is being read from a cache that's filled only upon boot.

[JdGordon]

none will be shown IFF the .wps and the .cfg both don't specify a backdrop. otherwise its a bug

[chrisjj]

Ah. I see your

 "If the .wps (or .fms etc) specify a backdrop image it is used, otherwise the config.cfg one is used so if there is none specified in the config none will be shown"

must have meant

 "If the .wps (or .fms etc) specify a backdrop image it is used, otherwise the config.cfg one is used, so if there is none specified in the .wps (or .fms etc.) and there is none specified in the config, none will be shown"

Then yes we agree. I do see that behaviour.

However I believe my

 "Surely clearing the browser/menus backdrop using Clear Backdrop as currently documented, should not clear the WPS backdrop even when they are the same backdrop."

still stands.

[JdGordon]

1) Clear backdrop resets the config.cfg so *NO* backdrop is specified
2) the wps checks the .wps for a specified backdrop and uses it
3) If none is found in 2) then the config.cfg backdrop is used.

THEREFORE is you had previously cleared the backdrop from the menu, and your .wps doesnt specify a backdrop NONE WILL BE SHOWN

[chrisjj]

Again, on that we agree.

However that makes

 "Surely clearing the browser/menus backdrop using Clear Backdrop as currently documented, should not clear the WPS backdrop even when they are the same backdrop."

false WHEN and ONLY WHEN "your .wps doesn't specify a backdrop".
