I am trying to get the thumbnail function to work. Yes, I am modifying the default fvwm2rc. It isn’t working for me. I’m new, so I may be missing something:

What version of FVWM are you using? (You need FVWM 2.5.X). Do you have imagemagick installed? You need that too.

– Thomas Adam

I am running Debian Etch.
Fvwm 2.5.18
ImageMagick installed.

What’s funny is if I use Taviso’s fvwm2rc I get the thumbnails. I can’t find what I am missing.

Well, looking at your config, nothing is calling Thumbnail whenever an iconify action takes place. You want something like:

DestroyModuleConfig FE-i: *
*FE-i: iconify Thumbnail

AddToFunc StartFunction I Module FvwmEvent FE-i

Also note that nothing is calling DeThumbnail either, hence you will want something like this as well:

DestroyModuleConfig FE-d: *
*FE-d: deiconify DeiconifyThumbnail

AddToFunc StartFunction I Module FvwmEvent FE-d

– Thomas Adam

Putting those lines in causes the window to “rebound” instantly, no inconifying, no thumbnails.

So don’t do that, remove the FvwmEvent for the “iconify” action and where you have “Iconify” actions for mouse/key bindings, replace them with calls to “Thumbnail”.

I’d personally be inclined to fix the function to work via the iconify FvwmEvent, but that’s just me. Much more flexible.

– Thomas Adam

That did it. It isn’t ideal, no, but I just wanted to get basic functionality I could build on.

Is there is a way to speed up the thumbnail function? There is a visible delay between hitting the UI to thumbnail and when it actually does it’s thing.

No - this is the price you pay.

– Thomas Adam

For using thumbnails or not using FvwmEvent?

For using Thumbnails. There’s a fair amount of processing which takes place behind the scenes. On a slow computer you may well notice the effects, but that’s just a caveat of your using it.

The FvwmEvent comment was simply an observation the the Thumbnail function is poorly designed – it should not rely on encompassing Iconification itself.

– Thomas Adam

Ah, I see. I’m now going to work on getting FvwmEvent working with this. Thanks!

I use this instead:

DestroyFunc Thumbnail
AddToFunc Thumbnail
+ I Raise
+ I ThisWindow (!Iconic) SetEnv Icon-$[] $[w.iconfile]
+ I ThisWindow (!Shaded, Iconifiable, !Iconic) Piperead \
        "xwd -silent -id $[] > $[FVWM_USERDIR]/tmp/icon.tmp.$[].xwd"
+ I Iconify
+ I Exec convert $[FVWM_USERDIR]/tmp/icon.tmp.$[].xwd -scale 128 -frame 1x1 \
        -mattecolor black -quality 0 png:$[FVWM_USERDIR]/tmp/icon.tmp.$[].png && \
        FvwmCommand "WindowId $[] WindowStyle IconOverride, Icon $[FVWM_USERDIR]/tmp/icon.tmp.$[].png"

DestroyFunc DeThumbnail
AddToFunc DeThumbnail
+ I PipeRead "echo Test \\(i \\$\\[Icon-$[]\\]\\) WindowStyle Icon \\$\\[Icon-$[]\\]"
+ I TestRc (NoMatch) WindowStyle NoIconOverride, Icon
+ I Exec rm -f $[FVWM_USERDIR]/tmp/icon.tmp.$[].png
+ I All (Iconic, CurrentPage) PlaceAgain icon
+ I UnsetEnv Icon-$[]

The main difference is that I use Exec instead of Piperead for the convert stage. That means that, at least, I can continue working without any delay, because the function does not sit waiting for convert to finish its work.

The downside is that for a moment, the iconified window will not show the thumbnail, but who cares about that? :stuck_out_tongue:

There also another way: write a small program in C using imlib to do the conversion, instead of using imagemagick. Imlib is much faster. I think that there was a thread around about that… try looking for “fast thumbnails” or something like that.

This is a duplicate. I remember discussing this before, and having the same silly conversation about Exec/PipeRead then.
