API changes here, all in order to make E-Disk and E-MemWatch be able to toggle
between the old arrangement and the new. So basically, you can now move
gadgets to new locations.

Dammit. My Linux version checking was broken in net.c, so users of 2.1 and
2.2 kernels weren't getting outgoing packet counts. Fixed.

settings that you want to refer to under the same key (e.g. the apps that
a launcher starts up etc), use
void Epplet_modify_multi_config(char *key, char **values, int num);
And if you want to query for a group of settings, use this:
char **Epplet_query_multi_config(char *key, int *num);
Note that you have to free() the returned array here. The key is internally
encoded into __key__1 for the first string, __key__2 for the second etc.
I put some testing code for this into ConfigTestEpplet.c The epplet will
remember all the command line parameters you give on startup and dump
them.
Also extended E-Mountbox so that the users can now define the patterns
in the device or mountpoint and corresponding icons themselves. Currently
still via the config file, but the dialog is there. Not functional yet,
though.

This should fix the seg fault people have been seeing. I also removed an
Esnprintf() and put the sprintf() back; that was a wrong replacement.

Don't try to open "/dev/null" as an image either.
Prevents those:

All fallbacks failed.

correct.

Urm. I don't know if this was intended, but E-Slides never actually
Epplet_gadget_show()'s its image... Don't know when this happened...

Commands to view urls in E-UrlWatch are now of the format:
command %s
Where %s is substituted with the url.
Eg. The default is now:
gnome-moz-remote --newwin "%s" &
But things like
netscape -remote openURL(%s)
will now work.
That's a really bad habit of mine :( Thanks to Matthew Crites
<mcrites@primenet.com> for pointing it out.

Hrm. If nobody minds... I've added:
Window Epplet_create_window_borderless(int w,int h,char *title, char vertical);
In case anyone fancies a borderless window. Or two. For displaying things. In
windows. Without borders. For whatever reason. Erm. I'll stop now.

The Mountbox reacts to left and right cursor keys now. Also added a Jazz drive
image for piercer <piercer13@home.com>. Config dialog coming soon.

Applied a patch from Michael Roberts <m.t.roberts@student.murdoch.edu.au> so
that invisible gadgets won't try to redraw themselves.

Config file support and a new config dialog for E-Time. You can set the
strings passed to strftime() for each line, and you can also set the text
justification (right or left).
SVN revision: 1546

Fixed a seg fault in E-Mountbox if the images in the config file aren't found.
It first falls back on the compiled-in defaults, and if that doesn't work
either, it exits with an error.

New dialog for E-NetGraph. This is the only network epplet I use, so I don't
have any plans to add similar interfaces to the other net epplets, but I
recommend that *someone* does so.
Also, I modified E-Slides and E-NetGraph so that if the config file or the
default settings don't provide a valid image directory (for E-Slides) or a
valid network interface (E-NetGraph), rather than immediately exiting, you
will be presented with the config dialog. Very handy.

Applied Tom's patch to E-Slides to support maintaining the aspect ratio when
displaying images in the epplet window. Also cleaned up the E-MoonClock code
and set the buffer size to 1024 so that everyone will hush. =)

By popular demand:
/* A cut down version for image-only buttons */
Epplet_gadget Epplet_create_image_button(char *image, int x, int y,
int w, int h,
void (*func) (void *data), void *data);
That's the last of them! No more =P
SVN revision: 1499
(gilbertt)
Oops. Make that:
/* A cut down version for text-only buttons */
Epplet_gadget Epplet_create_text_button(char *label, int x, int y,
int w, int h,
void (*func) (void *data), void *data);
/* A cut down version for stdimage-only buttons */
Epplet_gadget Epplet_create_std_button(char *std, int x, int y,
void (*func) (void *data), void *data);
STD images do not need w or h parameters.
=P

Added some less complex button functions, left the old one in place, so as
not to break anyone's lovely epplets :)
Here's what you got:
/* A cut down version for text-only buttons */
Epplet_gadget Epplet_create_text_button(char *label, int x, int y,
int w, int h,
void (*func) (void *data), void *data);
/* A cut down version for stdimage-only buttons */
Epplet_gadget Epplet_create_std_button(char *std, int x, int y,
int w, int h,
void (*func) (void *data), void *data);
Those window things in the original one should really be buried in the api,
and not public, but I won't break anyone's code. There ya go :)

Okay. E-ScreenSave now has a working config window which actually changes
the things config! Its really basic, 'cos the epplet is really basic, but it
works. Press the configure button to see it :)
It has working Ok, Apply and Cancel buttons, try them and see. There is
always a dilemna over how stuff like this should work, but in my epplets at
least, cancel undoes everything you changed since opening the window, even
stuff you "apply"ed. See it for yourself, it was really easy to do ;)
Hey StriderZ, there's a textbox on there too :) I'll be talking to you later
about that =P
SVN revision: 1495
(gilbertt)
So, say hello to Epplet_create_window_config.
It rules ;)
Here's the definition:
Window Epplet_create_window_config(int w,int h,char *title,
void (*ok_func) (void *data),void *ok_data,
void (*apply_func) (void *data),void *apply_data,
void (*cancel_func) (void *data),void *cancel_data);
You can picture what it does, and check it out in E-ScreenSave. (Press the
"Lock" button).
The cool thing is that if you supply NULL for any of the callbacks, that
button won't be added to the dialog. So, for an Ok, Cancel dialog, just
supply NULL for apply_func.
I have added explanation to the epplet.h file, and would like people to bang
at this now? I will set my epplets up to use the new functions fully over
the weekend. This will help me find any problems, as I haven't tested adding
every type of gadget to config windows yet, there may still be redraw issues
I missed.
Its pretty nice now though, and I have checked for memory leaks and bad
handling, please point out anything dubious you see. The api will become
more rich over the next few days, then it should stabilise.
Any feature suggestions, send 'em now :)
SVN revision: 1493

Okay. Lots has changed. It was pretty inconsistant to have loads of
functions returning or requiring a "Window win" paramater, and mine dealing
with "Epplet_window" parameters. I had to lose one, so I lost the one which
caused no breakage. Mine :)
I still use Epplet_window internally to encapsulate data on a per-window
basis. However, all public functions deal with "Window win" again. Now
things are consistant. The Epplet_window type is now private and hidden.
To do this, I have implemented a little lookup function to relate
Epplet_windows to Windows, which should be more than adequate for our needs.
You can now declare a delete event handler for your whole epplet, although I
may change to per-window delete event handlers if people request it.
If you return 1 from the delete event handler, or don't supply one, or
supply NULL, the window will be destroyed for you, if you return 0, the
delete event will be ignored. Use this to do things like saying "hrm, those
two settings cannot coexist" or "that file does not exist" etc.
I'm nearly finished with the window functions now, and will next add
convenience wrappers such as Epplet_create_window_config(...) to add ok,
apply and save buttons and setup callbacks for you, and some other stuff
too.
I'd appreciate it if people would poke around and see what they think, I'm
new at this Xlib stuf...

Removed the int x, and int y properties for Epplet_create_window, as they
were pretty pointless, and I hate it when windows decide where they should
go ;)
SVN revision: 1487
(gilbertt)
Right. You can now specify a "vertical" property for your new window. Works
the same as the vertical parameter in Epplet_init. Uses the same
imageclasses too.
I had a big headache debugging this, it just didn't seem to work, I knew
BrushedMetal (the theme I use) had a different (green) vertical pixmap, but
the windows always came up grey. Just when I was about to go mental, I found
this in epplet.cfg:
__ICLASS __BGN
__NAME EPPLET_BACKGROUND_HORIZONTAL
__NORMAL "epplets/images/bg.png"
__EDGE_SCALING 2 2 2 2
__END
__ICLASS __BGN
__NAME EPPLET_BACKGROUND_VERTICAL
__NORMAL "epplets/images/bg.png"
__EDGE_SCALING 2 2 2 2
__END
Gah. No wonder the images weren't changing!
Is there a reason for this? If not, could it be changed to:
__ICLASS __BGN
__NAME EPPLET_BACKGROUND_HORIZONTAL
__NORMAL "epplets/images/bg.png"
__EDGE_SCALING 2 2 2 2
__END
__ICLASS __BGN
__NAME EPPLET_BACKGROUND_VERTICAL
__NORMAL "epplets/images/bg_v.png"
__EDGE_SCALING 2 2 2 2
__END
Please?
Anyway, the vertical stuff works now, and probably did an hour ago, before I
went off chasing nonexistant bugs :)
I also tidied up some other stuff, and killed another global :)
See E-ScreenSave in cvs for an example, press the "lock" button to see it in
action :)

Should prolly free the background pixmaps when I destroy a window, right?
Thought so.
I was wondering where all my memory was going...

More config window stuff. Fixed a memleak, and now destroying an
Epplet_window also destroys any child gadgets attached to the window. I
think this works better, let me know otherwise.
I also cleaned up a couple of things, fixed adding buttons to new windows,
and improved the test epplet to be a better demo (E-ScreenSave right now).
I removed the Epplet_draw_window* functions, 'cos I don't need them :) What
I actually needed to do was fix Epplet_draw_image - so I have :)
Lots more to do tonight :)
SVN revision: 1483
(gilbertt)
Ok. More config window stuff.
Fun fun. I had to create a new type, Epplet_window to hold some window info,
and a stack to push and pop contexts for adding gadgets to different new
windows. This stuff works real well, and I am chuffed with it :)
The extra windows now redraw themselves on exposes, and new gadgets can be
added to them successfully. W00p.
I had to implement some new stuff, so please check nothing is broke (I am
not finished, but I don't want to commit code that breaks stuff).
Here are some details on the new stuff :)
---------------
PUBLIC STUFF
typedef struct epplet_window
{
Window win;
int w;
int h;
Pixmap bg_pmap;
Pixmap bg_mask;
Pixmap bg_bg;
}EppWindow;
typedef EppWindow *Epplet_window;
Epplet_window Epplet_create_window(int w,int h,int x,int y,char *title);
void Epplet_window_show(Epplet_window win);
void Epplet_window_hide(Epplet_window win);
void Epplet_window_destroy(Epplet_window win);
void Epplet_window_push_context(Epplet_window newwin);
Epplet_window Epplet_window_pop_context(void);
---------------
PRIVATE STUFF
static Epplet_window context_win; /* Current context win */
static int window_stack_pos; /* For context changes */
static Epplet_window window_stack[20]; /* For context changes */
static Epplet_window mainwin; /* Always the main epplet window */
static int window_num = 0; /* For window list */
static Epplet_window *windows = NULL; /* List of windows to loop though */
/* For Keeping a list of windows owned by the epplet, to loop through and
* do stuff with. */
static void Epplet_register_window(Epplet_window win);
static void Epplet_unregister_window(Epplet_window win);
/* Redraw all epplet windows (excluding the main epplet window) */
static void Epplet_draw_windows(void);
/* Redraw window win */
static void Epplet_draw_window(Epplet_window win);
/* Refresh window backgrounds on theme change */
static void Epplet_refresh_backgrounds(void);
-------------
I also added an item to GadGeneral so that I can find what window a gadget
was created on:
typedef struct gad_general
{
GadType type;
char visible;
Epplet_window parent;
}
GadGeneral;
-------------
Not to mention the reworking of code which draws or handles windows.
I have more tinkering to do in the event handling, to catch delete_events,
and to filter out mouseovers etc for separate windows. Tomorrow :)

For one thing, I think I've fixed the seg fault in E-MoonClock. Here's
hoping.
I also added the background setting functionality to E-Slides, but this time
it was done *right*. :-) Take a look and see for yourself. If you look at
the code, it also demonstrates how to use E IPC to set backgrounds.
SVN revision: 1476

api changes.
Ok. I have added some functions to the api, they are not yet perfect, but
they compile cleanly and don't create any problems. Don't use them yet
though, the api may change.
Window Epplet_create_window(int w,int h,int x,int y,char *title);
void Epplet_window_show(Window win);
void Epplet_window_hide(Window win);
void Epplet_window_destroy(Window win);
void Epplet_window_switch_context(Window newwin);
void Epplet_window_reset_context(void);
All of these functions are in place and work. I have yet to add code to
handle delete_events. At the moment, if you close the dialog window, the
epplet exits. This is clearly not intended ;) I'll fix it tomorrow, its late
here now.
You can even switch context and add widgets to your new window with no
problems ;)
Other things to fix tomorrow is the event handling stuff which assumes only
one window will be around...
I am currently using E-ScreenSave as my test epplet for this code, as I know
only about 2 people use it ;) Try it to see the code working.
SVN revision: 1472

E-ScreenShoot.c E-SD.c E-ScreenSave.c
Urm. Should've done this before. Removed some duplication, and one omission
in my cloaking code. Silly really, most people won't notice any difference,
but I will :)
