You may want to (conditionally) add:
gtk_signal_emit_stop_by_signal (w, "button_press_event");
in the handler to prevent the button press(es) from having their usual
effect. Or you may not.
all clear?

ok, lets go from the way begining:
1. i create combo box:
combo2 = gtk_combo_new ();
and assign signal handler:
gtk_signal_connect_object(GTK_OBJECT (GTK_ENTRY(GTK_COMBO(combo2)->entry )) ,
"key_press_event", GTK_SIGNA
L_FUNC(my_func),GTK_OBJECT (GTK_ENTRY(GTK_COMBO(combo2)->entry)));
2. inside my_func
void my_func (GtkWidget* widget, GdkEventKey* event, gpointer data)
ev = event->type;
printf ("event->type = %d\n", ev); - get 8 all the time (key_pressed)
switch (event->keyval) {
case GDK_Up:
... do smth. usefull...
and try to stop emission to prevent focus-out:
gtk_signal_emit_stop_by_name (GTK_OBJECT (widget), "key_press_event");
no errors, but after press focus goes out (it hapened before !!!
release )
i tried also return TRUE | FALSE instead of void.
question is: why signal "key_pressed" doesn't stop and goes further to
focus-handler?
PS: i partially solved this problem by using
gtk_combo_disable_activate(GTK_COMBO(combo1));
gtk_combo_set_use_arrows_always (GTK_COMBO(combo1), TRUE);
in developer version, but it's not what i'd like to :(
PPS: you can see all the src here: www.enlight.ru/ptkdic/
any ideas?

combo box
hi,
i'd like to rebind default keys of cobmbo box like , , ,
etc.
...
combo1 = gtk_combo_new ();
...
gtk_signal_connect_object(GTK_OBJECT
(GTK_ENTRY(GTK_COMBO(combo1)->entry )) , "key_press_event", GTK_SIGNAL_FUNC(my_func),
GTK_OBJECT (GTK_ENTRY(GTK_COMBO(combo1)->entry)));
my_func (GtkWidget* widget, GdkEventKey* event, gpointer data)

case GDK_Up:

gtk_signal_emit_stop_by_name (GTK_OBJECT (widget), "key_press_event");
gtk_signal_emit_stop_by_name (GTK_OBJECT (widget), "key_release_event");
break;
...
}
... to prevent focus moving out of entry.
all works, but i'm getting:
Gtk-WARNING **: gtk_signal_emit_stop(): no current emission (27) for object `GtkEntry'
and sigsegv some time.
if i remove any of two lines with gtk_signal_emit_stop... or swap
order - focus going out of combobox's entry.

[gtk] GTK on memory framebuffer?
Hi all, One of the projects we are looking at right now has a really tight deadline for a customer demo. (that is, our customer wants to demo it to somebody else) We are putting together a clunky demo unit for the first pass as a proof of concept. It runs a linux 2.4.6 variant on an ARM processor, which has an LCD framebuffer memory mapped. We do not currently have any kernel mode LCD or framebuffer drivers. We do, however, have a user mode driver. That is, we can compile writes to the framebuffer into an application via writing raw data. Ultimately we plan on using kernel mode drivers and using gtk for our gui widgets. Now the question: Can gtk act on a pure bitmap/framebuffer image (defined only as a data structure), or does it need to act on the actual devices of display? If it can operate on a raw image, we can easily do some blitting back and forth between two bitmaps kept in memory; the one not being displayed is the one modified, until it gets swapped with the currently displayed bitmap. Is this possible with Gtk? This would allow us to use Gtk for our development for the demo, and allow us to keep the overall architecture for the post-demo development. While i'm at it, has anybody else compiled Gtk for the ARM architecture? cheers, cam ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list
./configure can't find X
Hi there,
anybody willing to help me out? I'm trying to install gtk+-1.2.10 on
RedHat7.1 (2.4.2-2). The ./configure script
crashes when it tries to find X, these are its last lines:
checking for X... no
configure: error:
*** X libraries or include files not found. Check 'config.log' for
*** more details.
The relevant lines of config.log are:
configure:4544: checking for X
configure:4611: gcc -E conftest.c >/dev/null 2>conftest.out
configure:4607:27: X11/Intrinsic.h: No such file or directory
configure: failed program was:
#line 4606 "configure"
#include "confdefs.h"

configure:4687: gcc -o conftest -g -O2 -Wall conftest.c -lXt 1>&5
configure: In function `main':

collect2: ld returned 1 exit status
configure: failed program was:
#line 4680 "configure"
#include "confdefs.h"
int main() {
XtMalloc()
; return 0; }
I don't seem to have a file called Intrinsic.h, so I guess it doesn't know
where to find the X11 libraries? I do have the Xt libraries, they're in
/usr/X11R6/lib, at least I have a file named libXt.so.6.0, and a sym link
to it called libXt.so.6. When I try to compile anything with gcc -lXt I
get "/usr/bin/ld: cannot find -lXt", even when I add -L/usr/X11R6/lib.
/usr/X11R6/lib is in my /etc/ld.so.conf file, and I've run ldconfig over
and over again.
Clearly there's something fundamental that I don't know about, please help
me out.
thanks a lot, mike

You have to add a line:

}

Set gc_light/dark color using resource?
HI!!! When gtk draws a 'raised' button of a certain background color, it draws the top and left edges in a somewhat lighter color (gc_light) and the bottom and right edges in a somewhat darker color (gc_dark). Is it possible to set these colors explicitly?

I didn't really understand everything (esp. about the floating reference, I don't exactly what this thing mean or is...). But I've tryed to add to my code a gtk_object_sink just after the creation of the canvas item. Then I've tryed to add instead gtk_object_ref and gtk_object_sink. And finally I've tryed gtk_object_ref only instead of the previous two commands. But in all this case I got the warnings. But I want to precise one thing. The unref operation occur in a callback of the canvas item. So one of them receive an action from the user and I have to unref this item and a second one (passed with the void* of the callback). The item that fired the event has a ref_count of 3 (instead I would expect 1) while the other one has a ref_count of 1 (which should be normal). I'm applying the unref to both of them, so after the unref execute there ref_count decremente of 1 (so respectively to 2 and 0). I'm getting a warning only on the second item but both are destroyed!!! (I guess this job is done when leaving the callback as at this moment I receive a second warning (again about this ref_count).) If you need I can send a extract of my code with all the involved parts. Again thanks all for your help, Have a nice day (or night)...

This would need a small amount of localized changes in GtkFB. Should be really easy. Just use the shadow buffer mode of GtkFB and make the shadow buffer updates update to your framebuffer by changeing the shadow_copy_rect function pointers in gtk+/gdk/linux-fb/gdkrender-fb.c:gdk_shadow_fb_init() to your own. You'd have to remove some stuff from the initialization code too. The parts that opens the framebuffer device and sets up resolutions etc. And you need to hardcode your framebuffer layout data (size, depth etc). > While i'm at it, has anybody else compiled Gtk for the ARM architecture?

Help - need some insight into experience.
Hi: Does GTK/GDK do anything before displaying the messages. Here is what I see. I compiled the messages using msgfmt as usual. The messages are iso-8859-1 compliant encoded. Then I set my local to ta_IN (I guess it is nolonger just ta). And the messages I see make no sense. They seem to be a collection of characters but no meaningful words. Then as a test I compiled my messages into en_GB (which I assumed would also be iso-8859-1 compliant) and then set my locale to en_GB. Now I see the messages but many of the characters in the extended ASCII set (128 - 255) are not displayed (about 12 of them). I can only conclude that GDK or something is doing/analyzing the locale and the encoding that locale expects and does something to the messages. Can anyone shed some light on this? If this is something that would need to be fixed in the future versions, I would verymuch like to talk to someone involved with glib/gtk/gdk to help fix this.

GTK doesn't, but gettext converts them into the locale's encoding, and GDK/GTK 1.2 require them to be in the locale encoding.

Given that, you need to use the correct encoding for the locale; for example, UTF-8 might work (try ta_IN.UTF-8 perhaps).

Re: Help - need some insight into experience.
I am trying to understand the flow of conversions and so please bbare with me: My messages are in iso-8859-1/15 format. I set my locale to ta_IN. I think the encoding for that locale is TSCII-0. Hence gettext tries to convert from iso-8859-1/15 to TSCII-0. The font used to display the messages is also iso-8859-1/15 compliant. Who do I contact about introducing versions of the ta_IN locale: e.g ta_IN.ISO8859-1/15. If I converted all my messages to UTF-8 (conversion from iso-8859-1/15 to UTF-8) can I still use my iso-8859-1 font or do I need Unicode fonts.

PHP-GTK: Scrolled Window whoes
Hi, Im having trouble with scrolled windows, I have an application that uses two scrolled windows, one with a table with GtkEntry boxes and another with a table with GtkButton, (Listed Vertically). When I scroll down and press one of the buttons (or entry boxes) the window automaticly scrolls up again. I though that assigning vadjustment would solve my problem, but it doesnt. What property am I missing? Must I set vadjument for the table? For the buttons/entry boxes ? Please help, Im a bit confused here. The code is like this: $scrolled_window = &new GtkScrolledWindow(); $scrolled_window->set_border_width(5); $scrolled_window->set_policy(GTK_POLICY_AUTOMATIC, GTK_POLICY_AUTOMATIC); $box1->pack_start($scrolled_window); $box2 = &new GtKVBox(false,2); $box2->set_border_width(5); $scrolled_window->add_with_viewport($box2); $box2->set_focus_vadjustment($scrolled_window->get_vadjustment()); ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list
generic MVC question
[ i'm not sure where else to discuss this. if anyone has some ideas on good MVC forums, let me know. thx. --p ] suppose you have a combined View+Controller. you use the Controller to attempt to change the Model. this usage changes the appearance of the View. the attempt to change the Model fails for some reason (e.g. an illegal value). what causes the View to be reset to the correct state? i ask because in a genuine MVC model, you never update the View based on the return value of a modifier function - the View is updated when notified of a change in the Model. in this case, there is no change in the Model, but the View is "stale" because it was modified to reflect what was happening in the Controller. if you combine View+Controller, do you have to always check for result of a Model modifier function, and reset the View if the function failed? or is there some better paradigm for this that i'm not seeing. --p ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list

Yes, I believe that's correct. > The font used to display the messages is also iso-8859-1/15 > compliant. Should not be. You have to use a font that supports the encoding of the locale. GTK's default font should support the locale encoding if: - you call gtk_set_locale(NULL) before gtk_init() - there is no warning message printed about "locale not supported by C library" - you actually have fonts in your locale's encoding If you load your own fonts, you need to use gdk_fontset_load() rather than gdk_font_load(); gdk_font_load() won't work properly because it doesn't automatically get the right font for the locale encoding. This all applies to GTK 1.2.x, the 1.3.x series is completely different (uses Unicode throughout, GdkFont replaced by Pango) > Who do I contact about introducing versions of the ta_IN locale: e.g > ta_IN.ISO8859-1/15. This is an operating system issue, it happens on the C library level. So it depends on the operating system. You shouldn't need to care about the encoding though - if your OS comes with ta_IN using TSCII-0, then it should also come with fonts that can be used in that encoding... It's possible your OS already supports ta_IN.ISO-8859-1, try setting your locale to that and it might work... > If I converted all my messages to UTF-8 (conversion from iso-8859-1/15 > to UTF-8) can I still use my iso-8859-1 font or do I need Unicode > fonts. With GTK 1.2 UTF-8 is not treated specially in any way. If your locale was a UTF-8 locale (ta_IN.UTF-8 or something), then yes you would need a Unicode font, and GTK should automatically use it. If your locale is iso-8859-1 then you need an 8859-1 font. And for TSCII-0 you need a TSCII-0 font. At least, I think so. Possibly the X fontset mechanism has some ability to use fonts from one encoding to emulate a font from another encoding, I'm not sure. Anyway, basically GTK 1.2 uses the locale model, which means that everything works in the locale's encoding. You can't choose your own encoding. GTK 1.3 instead works in UTF-8 encoding at all times, so you don't have those issues. Havoc ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list

SOLVED: PHP-GTK: Scrolled Window whoes
Well, I was really going in cicles. What I did was remove the focus_vadjustment from $box2 (the viewport for scrolled_window) and used it in the table containing the buttons / Entry boxes(that is then packed into $box2). What happens is: If I type a value into one box and then go down (pressing down arrow) when it reaches the last seen item, it scrolls automaticly, and also if I scroll down/up and click on an item, it works as expected. Without any set_focus_vadjustment, it works ok when scrolling, but it won't auto-scroll if I get past the last visible item.
