simple icon tray

[technosaurus]

Code: Select all

/* gcc `pkg-config gtk+-x11-2.0 --cflags` -Os -o sit sit.c -lgtk-x11-2.0 -s */
#include <gtk/gtk.h>
int main(int argc, char *argv[]){
	GtkStatusIcon *widget; int i=1;
gtk_init (&argc, &argv);
while (i<argc) {
	widget = gtk_status_icon_new_from_file(argv[i++]);
	gtk_status_icon_set_tooltip(widget,argv[i++]);
	gtk_status_icon_set_visible(widget,TRUE);}
gtk_main ();
return 0;}

fine print
This is not a full featured implementation by any means, only an easy way to show multiple status icons
I intentionally used deprecated widgets so as to be compatible with gtk+-2.10
(to use in gtk3 change gtk_status_icon_set_tooltip to gtk_status_icon_set_tooltip_text)

usage
sit /full/icon/path/icon.png "tooltip text" /path/to/another/icon.svg "another tooltip" ...

it draws extremely fast so it can be used in a shell daemon process thusly

Code: Select all

kill $SITPID
sit $ICON1 $TOOLTIP1 $ICON2 $TOOLTIP2 &
SITPID=$!

(for instance, if you need to change the tooltip or icon based on an event)

technosaurus,

Simple and elegant way to populate a tray with notifier icons.

Thanks,
s
(I see there's no limit to the number of icons- so you could make a kind of dashboard out of a tray )

[technosaurus]

I wanted something to complement my xpm percent bar generator and to test out an svg generator that I started. The whole idea was to allow a single daemon process to control all tray applets. I may make another version with callbacks that does stuff when you click on the icon... Possibly even monitor icons to refresh when changed.

[disciple]

What would be the idea of this?
Something like a music player controlled by several buttons in the tray?

Dear technosaurus,

Both the idea and implementation are great. A system call parameter on the command line - or a .sitrc file listing icons tooltips and progs-to-exec - would make a nice and tiny utility.

Thanks.

With kind regards,
vovchik

updated to icon tooltip action

build script with test/example implementation

Code: Select all

#!/bin/sh
#compile
gcc `pkg-config gtk+-x11-2.0 --cflags` -DGTK_NO_CHECK_CASTS -DG_DISABLE_CAST_CHECKS \
-Os -finline-small-functions -ffunction-sections -fdata-sections -fmerge-all-constants \

while read LINE; do
case "$LINE" in
 TAG)Xdialog --under-mouse --infobox "sit working" 0 0 &
 ;; 
esac
done

and the code

Code: Select all

#include <gtk/gtk.h>
#include <string.h>
#define write1(s) write(1, s, strlen(s))

void activate(GtkStatusIcon *b, gpointer s){write1(s);write1("\n");}

int main(int argc, char *argv[]){
	GtkStatusIcon *widget; int i=1;
gtk_init (&argc, &argv);
while (i<argc) {
	widget = gtk_status_icon_new_from_file(argv[i++]);
	gtk_status_icon_set_tooltip(widget,argv[i++]);
	g_signal_connect(GTK_OBJECT (widget), "activate", GTK_SIGNAL_FUNC(activate),(gpointer) argv[i++]);
	gtk_status_icon_set_visible(widget,TRUE);}
gtk_main ();
return 0;}

technosaurus,

Thanks for the added function.

I did run into something which puzzled me - if an svg is made with text only-

Code: Select all

echo '<svg>
   <rect width="64" height="64" x="0.5" y="0.5"
     style="fill:#90EE90"/>
   <text x="0.79569316" y="22"
     style="font-size:22px"
     >Text</text>
   <text x="1" y="48"
     style="font-size:22px;font-weight:bold"
     >Here</text>
 </svg> ' >/tmp/infoicon.svg

and then exec "sit /tmp/infoicon.svg" , it Segmentation faults.

That is a gtk/librsvg "feature" I think the school requires the header info in the svg tag.

technosaurus,

I tried -

Code: Select all

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 20010904//EN"
"http://www.w3.org/TR/2001/REC-SVG-20010904/DTD/svg10.dtd">
<!-- Created with Inkscape ("http://www.inkscape.org/") -->
<svg
   xmlns="http://www.w3.org/2000/svg"
   xmlns:sodipodi="http://sodipodi.sourceforge.net/DTD/sodipodi-0.dtd"
   xmlns:inkscape="http://www.inkscape.org/namespaces/inkscape"
   xmlns:xlink="http://www.w3.org/1999/xlink"
   id="svg1"
   sodipodi:version="0.32"
   inkscape:version="0.36"
   width="210mm"
   height="297mm"
   sodipodi:docname="/root/infoicon.svg"
   sodipodi:docbase="/root">
  <defs
     id="defs8" />
  <sodipodi:namedview
     id="base" />
  <rect
     width="64"
     height="64"
     x="0.5"
     y="0.5"
     style="fill:#90EE90"
     id="rect2" />
  <text
     x="0.79569316"
     y="22"
     style="font-size:22px"
     id="text3">Text</text>
  <text
     x="1"
     y="48"
     style="font-size:22px;font-weight:bold"
     id="text5">Here</text>
</svg>

And it didn't "segfault", but it did not render in the tray either - just an empty space.

UPDATE:

It apparently is a gtk version issue because I was trying it on Racy 522. I switched to Pup431 and it worked perfectly without the headers.

Now you see why I recommend gtk+-2.16.6 (and its glib version, which I think is the actual problem - that's where all the gobjects originate) with pango-1.24.5. When the gtk devs started prepping for gtk3, they broke a _lot_ of stuff.
It is soooo easy to patch programs that require newer gtk2 libs, because most things are just a rename to work with the g_* vs gtk_ namespace and things like *_set_tooltip was deprecated in favor of *set_tooltip_text (note that they didn't do something cool and allow some kind of _other_ tooltip to necessitate this) ... most of them can be fixed with a quick application of sed or a macro.
