 gtk2desklet 3.1
Subject description: (Was: gtkdialog-desklet) Convert many GTK2 programs into desktop apps |
|
This is a GTK module, which can turn many GTK based programs into a desktop app.
It is likely that the module may not succeed. Till now, I confirm gtkdialog, sylpheed, Xdialog, leafpad and thunar to be working.
You make the target program load the module by just passing an extra argument to the program:
| Code: |
--gtk-module=gtk2desklet
|
e.g.
| Code: |
gtkdialog3 --program=WIDGET --gtk-module=gtk2desklet
|
Hopefully, if the program is structured properly, the program's window will appear on the desktop, transparent, and without borders.
Download gtk2desklet-3.1.pet (15.9 KB)

akash_rawal,
Nice program. In testing I got this result. | Quote: |
# gtkdialog-desklet --help
mktemp: invalid option -- -
Usage: mktemp [-V] | [-dqtu] [-p prefix] [template]
|
Also, I wasn't sure exactly how to run this program- could you post some examples... perhaps the one for the "desklet_example.png" that you listed.
Thanks,
s

Wonderful 
Thanks a lot.
Would you become upset if I used this in Pwidgets ?

Just a tip 
A useful option to the <button> tags with this mthod is reliief="2" has-focus="false"
More shortly...
..later
Try this crazy script! (it's a bit of fun  , oh, and Pwidgets must be running)
| Code: | #!/bin/sh
WIDGETNAME=`basename $0`
#gif image to use (full path may be needed)
#this is the gif we use, I don't know if I can distribute
#so if it's not there then we download it
#http://caccioppoli.com/Animations/Navidad/54.gif
#you can use any image but you need to change X and Y
[ ! -f file.gif ] && \
wget http://caccioppoli.com/Animations/Navidad/54.gif
[ "$?" -ne "0" ] && echo "failed" && exit
mv *.gif file.gif
if [ -s file.gif ];then echo "ok"
else echo "woops, empty load, try again after ctrl/C"
rm -f file.gif
exit
fi
GIF=file.gif
#secreensize
SCREEN=`xwininfo -root | grep ' \-geometry ' | tr -s ' ' | cut -f 3 -d ' ' | cut -f 1 -d '+' | tr 'x' ' '`
HEIGHT=`echo -n "$SCREEN" | cut -f 2 -d ' '`
WIDTH=`echo -n "$SCREEN" | cut -f 1 -d ' '`
[ ! -d /tmp/santawidget ] && mkdir /tmp/santawidget #workdir
DESKBG=`cat /root/.config/wallpaper/bg_img`
resizepng "$DESKBG" /tmp/santawidget/background.png $WIDTH $HEIGHT 50 #resize and move bg
IMAGE=/tmp/santawidget/background.png #this is .png, makes life easier! It's the one we cut
NEWIMAGE=/tmp/santawidget/${WIDGETNAME}_background #this is the result
BGHEIGHT=`file $IMAGE| cut -d ' ' -f6|tr -d ','`
BGWIDTH=`file $IMAGE| cut -d ' ' -f4`
YDIMENSION=$(($BGHEIGHT - 400)) # 150 #`echo $(($HEIGHT - 300))` #hard code for demo
XDIMPRE1=$((${BGWIDTH} / 2))
XDIMPRE2=205
XDIMPRE3=$((${XDIMPRE1} + ${XDIMPRE2}))
XDIMENSION=$((${BGWIDTH} - ${XDIMPRE3}))
NEWIMAGEPATH=/tmp/santawidget #pixmap_path
IMAGEFILE=${WIDGETNAME}_background #_${WIDGETNAME} #our widget background
#REPLACE THESE dimensions if you use a different image file
#hard coded for demo
#we can do a quick dummy run and get the info from xwininfo if geometry \
#is variable
X=410
Y=289
#code based on /usr/sbin/background_reshape BK

#the magic #crop image using pamcut

{
function = FLAT_BOX

stretch = FALSE
}
}
}
class "GtkWindow" style "'"${WIDGETNAME}-background"'"' >/tmp/gtkwidgetrc
export GTK2_RC_FILES=/tmp/gtkwidgetrc
export gui='<window title="'"${WIDGETNAME}"'" type-hint="7">
<vbox>
<pixmap>
<input file>'"$GIF"'</input>
</pixmap>
<button has-focus="false" relief="2" tooltip-text="click to stop">
</button>

gtkdialog -p gui -G +${XDIMENSION}+${YDIMENSION} #${X}x${Y}

01micko,
Nice tip and polished stars for the widget 
Just a couple of corrections -

[ "$?" -ne "0" ] && echo "failed" && exit
BGWIDTH=`file $IMAGE| cut -d ' ' -f5`

Hello,
I get as far as "OK"..
Then I get:
| Quote: | ok
./gtkdialog-desklets: line 53: pamcut: command not found
pnmtopng: Error reading magic number from Netpbm image stream. Most often, this means your input file is empty.
** (gtkdialog:3246): WARNING **: Pixbuf theme: Cannot load pixmap file /tmp/santawidget/gtkdialog-desklets_background: Image file '/tmp/santawidget/gtkdialog-desklets_background' contains no data
(gtkdialog:3246): GdkPixbuf-CRITICAL **: gdk_pixbuf_get_width: assertion `GDK_IS_PIXBUF (pixbuf)' failed |
The part I colored red repeats till I hit ctrl-c to stop it...
Where do I get "pamcut"???

Thanks seaside, I was a bit sloppy 
-
puppyluvr try pnmcut, I should have a test..
if [ `which pamcut` ];then CUT=pamcut
elif [ `which pnmcut` ];then CUT=pnmcut
else echo "sorry not cropping tool found" && exit
fi
obviously then you substitute pamcut with $CUT

Yes, I forgot to mention that I put-
ln -s /usr/bin/pnmcut /usr/bin/pamcut
at the top of the script.
Also one other correction-
BGHEIGHT=`file $IMAGE| cut -d ' ' -f7|tr -d ','`
I get the same pix errors, but it runs anyway....

s

Hello,
Works now...
Tried a few different images..
2 questions:
1. Why does pwidgets have to be running...?
2. Which part controls screen location..? I cant seem to find it..

Answers
1) It doesn't, but you do need resizepng from pwidgets, actually it's a MU proggy, or you could change it to vovchik's bacon version.. I forget the name. I was a bit hasty in posting this morning!
2) XDIMENSION and YDIMENSION
Actually, I just had a moment to look at the code, I changed the file.gif test to an if statement, easier for me to fit in more!
Thanks to akash_rawal's work for the inspiration

Sorry for responding late.
Upgraded to version 1.0
Changelog:
- Now using gdk-pixbuf library instead of pnmcut, transparency is now displayed much faster.
- Now using JPEG format instead of PNG, much faster.
- Several compatibility issues fixed.
- Help and examples added at /usr/share/doc/gtkdialog-desklet
- Response to wallpaper change has been improved significantly.

Not at all 
You may use it the way you want.

I observed this issue in Puppy 430. This issue has been fixed in version 1.0 .
In addition, I observe another issue.
type-hint="7" tag isn't working in 430.
Seems to be a problem in GTK.

Nice!
I made a useful widget... I have more too, will post later when I fine tune them. | Code: | #!/bin/sh
#named "ramGTK"
WIDGETNAME=`basename $0`
export TOTRAM=`free -m|grep ^Mem|awk '{print $2}'`
freeramfunc(){
while [ 1 ]; do
USEDRAM=`free -m|grep ^Mem|awk '{print $3}'`
FREERAM=`free -m|grep ^Mem|awk '{print $4}'`
echo $(($USEDRAM * 100 / $TOTRAM))
echo "RAM $FREERAM MB"
sleep 1
continue
done
}
export -f freeramfunc
export ramwidget="<hbox>
<progressbar width-request=\"140\" height-request=\"14\" tooltip-text=\"showing free RAM of total $TOTRAM\">
<input>freeramfunc</input>
</progressbar>
</hbox>"

Great widget, but I had to make some modifications to make it work on lucid puppy 511.
Portability issues are always a headache. If only there was a thread dealing with writing portable shell scripts.
| Code: |
#!/bin/sh
#named "ramGTK"
WIDGETNAME=`basename $0`
export TOTRAM=`free|grep Mem|awk '{print $2}'` #Removed '-m' option
freeramfunc(){
while [ 1 ]; do
USEDRAM=`free|grep Mem|awk '{print $3}'` #Removed '-m' option
FREERAM=`free|grep Mem|awk '{print $4}'`#Removed '-m' option
echo $(($USEDRAM * 100 / $TOTRAM))
echo "RAM $FREERAM MB"
sleep 1
continue
done
}
export -f freeramfunc
export ramwidget="<hbox>
<progressbar width-request=\"140\" height-request=\"14\" tooltip-text=\"showing free RAM of total $TOTRAM\">
<input>freeramfunc</input>
</progressbar>
</hbox>"
gtkdialog-desklet -p ramwidget -c

It may, but this is not a full widget platform. It's a way to write programs, just like gtkdialog.

It's like Christmas . . . wait a minute it is Christmas . . .
Thanks guys - Mick I had to move resizepng to the bin directory (remembering to right click on it and change permissions to make runnable)
What fun. Will we be seeing its use in Slacko 5.3.2, or in Saluki 004 I wonder . . .
