Bonsoir,
Thanks.

Why? Very strange indeed!: It is a pity...

Only by completely rewriting an alternative statusicon widget.

Perhaps 'yad' could be used to make such a 'simple icon tray' and should offer more capabilities?

?? Rolling Eyes
It is already the case and this is why the world is "heading nowhere"!
(I'm probably missing something, but I don't really see the connection with the subject of this thread). Embarassed

I like FLTK quite a bit, it keeps improving and making things easier, rather than removing functionality.
You can make very small programs easily with FLUID to design the UX.

Might be something for other posters here to consider.

Yad is also gtk based, so no.

Fltk doesn't have a tray icon widget.

tcl/tk does
qt does

I did find an old X11 example here :
Code:
#include <X11/X.h>
#include <X11/Xlib.h>
#include <X11/Xutil.h>
#include <X11/Xatom.h>
#include <stdio.h>

typedef enum systray_opcode_tag {
        SYSTEM_TRAY_REQUEST_DOCK   = 0,
        SYSTEM_TRAY_BEGIN_MESSAGE  = 1,
        SYSTEM_TRAY_CANCEL_MESSAGE = 2
} systray_opcode_t;

void send_message(
        Display *disp,
        Window dest,
        systray_opcode_t message,
        long data1,
        long data2,
        long data3)
{
        XEvent ev;

        memset( &ev, 0, sizeof(ev)) ;
        ev.xclient.type = ClientMessage ;
        ev.xclient.window = dest;
        ev.xclient.message_type = XInternAtom( disp, "_NET_SYSTEM_TRAY_OPCODE", False );
        ev.xclient.format = 32 ;
        ev.xclient.data.l[0] = CurrentTime ;

                        printf("\tdata1 0x%X\n", ev.xclient.data.l[3]);
                        printf("\tdata2 0x%X\n", ev.xclient.data.l[4]);
/* container window could be got from ReparentNotify */
                        if( ev.xclient.data.l[1] == 0)
                                container = ev.xclient.data.l[3] ;
                        break;
                default:
                        ;
                };
        }
}

It would be a good exercise to adapt this to xcb or netsurf framebuffer and possibly use stb_image and libtinysvg for the images.

Hi,
I simply meant that FLTK is great for making simple programs to use with sdesk. It is very easy to mockup a design and keep all the code in FLUID. This makes it very simple for others to adapt the UX for their own purposes, or change it.
I have taken to causing my programs to read the .jwmrc file to set colors.

sdesk does all the work to set the tray icon, so FLTK does not need to Smile

Plus FLTK is not as crazy as GTK. It seems like more and more things change and become more complex (for no reason?) with each release.

I'm thinking about adding support for apps similar to:

Any thoughts

that looks pretty interesting!
I'll have to look more into that, but it seems like a really useful program.

technosaurus, I think it would be cool to modify the -t portion to allow checking for the icon theme icons, using:
gtk_icon_theme_load_icon ("icon_name")
it would be nice if this could be modified during runtime, as then things like a battery/wifi/wtc... could update the icon at will using a generic icon name that could be changed to fit the icon theme used.

So a few questions..
Is this possible in Puppy?

Would this be too hard to implement for you?

It may be easier to just try that if the image file fails to load normally, just use the contents of the file as the name.

It already allows this to be changed at run time though, just touch the symlink or change it.

1. Is this last source code of sit ?
http://www.murga-linux.com/puppy/viewtopic.php?p=714677#714677

2. Can you put 64 bit support to " build " file ?
For example:

Code:
#!/bin/sh
#compile

if [ `getconf LONG_BIT` = "64" ]; then
   echo "ARCH: 64-bit"

   #compile
   gcc `pkg-config gtk+-x11-2.0 --cflags` -DGTK_NO_CHECK_CASTS -DG_DISABLE_CAST_CHECKS \
   sdesk.c -o sdesk `pkg-config gtk+-x11-2.0 --libs` && strip --strip-all -R .note -R .comment sdesk

else
   echo "ARCH: 32-bit"

   #compile
   gcc `pkg-config gtk+-x11-2.0 --cflags` -DGTK_NO_CHECK_CASTS -DG_DISABLE_CAST_CHECKS \
   -Os -fmerge-all-constants -mno-accumulate-outgoing-args -march=i486 -mtune=i686 \
   -Wl,-O2,--gc-sections,--as-needed,--sort-common,-s sdesk.c -o sdesk \
   -lgtk-x11-2.0 -lgdk-x11-2.0 -lgio-2.0 -lgobject-2.0 -lglib-2.0

   strip --strip-all -R .note -R .comment sdesk

fi


3. Can you put or move source code to first post ?
4. Can you add version to source code ?


Edit:
From X11 http://murga-linux.com/puppy/viewtopic.php?p=828027#828027

Code:
$ ./buildsit
ARCH: 64-bit
sit.c: In function ‘send_message’:
sit.c:23:9: warning: incompatible implicit declaration of built-in function ‘memset’
         memset( &ev, 0, sizeof(ev)) ;
         ^

//usr/lib/x86_64-linux-gnu/libX11.so.6: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status



Edit:
sit-1.0.tar.gz from http://murga-linux.com/puppy/viewtopic.php?t=76431
I upgraded to sit-1.0-2.tele.tar.gz ( is in attachment )
- added own example with icon ( left click , right click icon tray )
- added support for 64bit in "build" script ( I get help for this on other forum )

But this have bugs:
- "right click" window sometimes is in at the top, bottom
- Working on Debian 8.8 ( Mate 64bit ) , but probably not working on Ubuntu ( I'm not sure )


Edit:
I tried rebuild sdesk to sdesk-1.0-3.tele ( file in attachment )
http://www.murga-linux.com/puppy/viewtopic.php?p=714677#714677
- added 64bit support
- added test script

but
- I can run function only from file ( this is good )
- I don't know how working <status icon> , can you add example ?


Edited:
I added to sdesk-1.0-3.tele second example ( now it is sdesk-1.0-4.tele
How get sdesk pid to kill only first or second app ?

Hello all.

"Tele", second post up, provided a 64 bit sdesk in his archive.

Here is a 32-bit version. Compiled on xenialPup-7.0.6 (ubuntu's glibc-2.23), using tele's
build script. For those Puppyists who have older machines and do not know how to compile.

You may have to redo the build if you are on a Puppy with a lesser C library.

Enjoy.

~~~~~~~~~~~~~~~~~~

If it may help some Puppyists understand how sdesk works, here is a one-liner that
I wrote using it, followed by sdesk's usage.
Code:
#!/bin/bash
# BoussPart-sdesk.sh
#### set -xe
sdesk -t /root/.aewm/ae/boussole_4a-32x.jpg "Orientation" "/root/.aewm/ae/boussole2.sh" "/root/.aewm/ae/disques-musher0.sh" 2>/dev/null
# 1 ## 2 ###### 3 ######################## 4 ########## 5 ####################### 6 ############################# 7 #
# See explanation of the numbers below.
# set +xe
exit

############

1) the sdesk command
2)  "-t" stands for "tray utility"
3) the filename of a png icon
4) the label which will appear as "notification" when the mouse hovers over the icon
5) the 1st app or script, launched by clicking the main mouse button on the left
6) the 2nd app or script, launched by clicking the main mouse button on the right
7) optional, if you wish or need to send whatever warnings there may be to "null".
(Not all systems issue warnings and pseudo-warnings, but Ubuntu just loves
printing them out.)

############

sdesk usage:
./sdesk [-i files] [-b] -t image tooltip left-action right-action ...
  -i           full path to file(s) with shell functions to include
                   by default it looks in /usr/share/sit/func*
  -b <file>    use image file as desktop background image
  -t           tray icon: must have the following parameters
  image        full path to image file
  tooltip      full path to tooltip file or a "quoted tooltip"
  left-action  action to run when left mouse button is clicked
  right-action action to run when right mouse button is clicked
############

~~~~~~~~~~~~~~~~~~

NOT sorry for being so verbose! Some of you advanced devs do NOT realize that you
are now at a high level of abstract thinking -- and how far removed you are now from
the average user's understanding of things.

How many times do we have to repeat the following:

"IF A DEV DOES NOT WRITE AN UNDERSTANDABLE DOC TO ACCOMPANY HIS /
HER UTILITY, IT IS AS IF (S)HE HAD NOT WRITTEN IT, BECAUSE NO ONE WILL
KNOW HOW TO USE IT." (Capitals intentional.)

Technosaurus' "sit" has been around over 5 years, and its derivatives. How many
people know of them or are using them?

It took me a full day figuring out how to use this sit / sdesk utility, and I am an
ADVANCED user. Will the average or newbie Puppyist be as persevering or as
patient?... I doubt it.

I'm looking for good examples of them being used.

What I would like to do would be to have tray icons for drives that are mounted to write to with color and/or text to tell me if they are getting too full.

Thanks...
