Hi

I use the thumbnail code ogf sacha with imlib2 (http://fvwm.lair.be/viewtopic.php?t=190&highlight=thumbnail)

The thumbnail function do not work with qt applications, those ones are irremediably iconified even if I can do by hand a thumbnail of them!

My thumbnail function is:

DestroyFunc	Thumbnail
AddToFunc	Thumbnail
+ I Raise
+ I SetEnv Icon-$[w.id] $[w.IconFile]
+ I ThisWindow (!Shaded, Iconifiable, !Iconic) PipeRead \
    "/$[fvwm_scripts]/thumb $[w.id] $[fvwm_icon_size] /dev/shm/icon.tmp.$[w.id].png; \
    composite -geometry +5+5 $[w.MiniIconFile] \
    /dev/shm/icon.tmp.$[w.id].png /dev/shm/icon.tmp.$[w.id].png; \
    echo WindowStyle IconOverride, Icon /dev/shm/icon.tmp.$[w.id].png"
+ I Iconify

Even with the taviso’s function, the thumbnailing of a qt apps does not work!

Any idea???

There’s nothing special about QT applications in this regard – I assume the function works OK with other applications? Indeed, how are you calling the function?

Ok Thomas I use code in the future sorry for that :blush:

The thumbnail function uses a binary named thumb compiled from the c code of Sacha.

Then I can run the binary from the command line like that:

./thumb window-id 128 test.png

and it creates a thumbnail called test.png. I get the window id simply with fvwm ident.

My thumbnail function uses thumb to create a thumbnail which will be used as icon.

This function work fine with other applications, I simply call it from:

Mouse 0 6 A Thumbnail

as usual.

Hi

I was wrong!!! :blush: I did bull-shit in my thumbnail function with the composite of the miniicon… it was not possible to do a thumbnail of the qt-apps because then don’t have a miniicon defined… So now I test the existence of the miniicon before doing a composite!

The right code is:

[code]DestroyFunc Thumbnail
AddToFunc Thumbnail

  • I Raise
  • I SetEnv Icon-$[w.id] $[w.IconFile]
  • I ThisWindow (!Shaded, Iconifiable, !Iconic) PipeRead
    “/$[fvwm_scripts]/thumb $[w.id] $[fvwm_icon_size] /dev/shm/icon.tmp.$[w.id].png;
    echo WindowStyle IconOverride, Icon /dev/shm/icon.tmp.$[w.id].png”
  • I TestRc (Match) Test (f $[w.miniiconfile], f /dev/shm/icon.tmp.$[w.id].png) PipeRead
    “composite -geometry +2+4 $[w.miniiconfile] /dev/shm/icon.tmp.$[w.id].png
    /dev/shm/icon.tmp.$[w.id].png; echo Nop”
  • I Iconify
    [/code]

soory once more… :blush:
