Dynamic color setting of GtkListStore/TreeStore selection cursor
Hello, I have a question regarding the color of the cursor/selection of the selected item(s) in a GtkListStore or GtkTreeStore. I'm currently able to set the colors of individual cells by associating the 'foreground'-property of a TreeViewColumn/CellRendererText to a certain column in a liststore. That works nice, but the selected item(s) remain in a certain default theme-determined color. It would be nice if there were some 'foreground selected' and 'background-selected' properties. For instance, if I have cells with a black background and colored text, then it would be nice if the selected items are not in the default theme color. Instead, they should have black text and the associated color as the background (i.e inverted). Is this possible? Anyone a useful hint for me? :) Thanks for your time in advance, Greetings, Raymond Dresens. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
How to align buttons in GtkHButtonBox?
Hi, Is it possible to get the buttons of a gtk_toolbar to align to the left side of the widget (the same behaviour as gtk_button_box_set_layout(button_box, GTK_BUTTONBOX_END))? I could not find anything in the widget's hierarchy that would do it and packing it into a GtkAlignment does help either.

If you decide to use the verb--noun design, I'd recommend hiding the Theme Name field until the user actually clicks on Create a new theme or Modify an existing theme. I would try to reduce the amount of unnecessary fields and boxes whenever possible. Ok, thanks. For all in the thread, I have for the time being abandoned the all in one dialog - just too many concepts at once. I currently have a separate New and Open dialog, but I may revisit it in the future.

Wrting to a text file in N800 /media/mmc1
Hi All,
Does any Hildon or gtk API supports writing into text files my following
code written in C is not
working for N800 which works perfectly fine under MAEMO ARMEL
mode.Please if some
one has some information let me know...

Hi All,
I just checked in N800 the following program for writing into a file which
doesn't work Any clues what is going wrong? I neither get any error not
it is
creating a file and writing into it.
#includestdio.h
void main()
{
FILE *Gfile;
if ((Gfile = fopen(/media/mmc1/test.txt, w+)) == NULL)
{
printf(Error in file creation);
}
if(Gfile)
fprintf(Gfile,%02x,0x10);
fclose(Gfile);
}

Forking from Gtk
Hello,
I have a small demo app. This works on FreeBSD but I can't
get to work on Linux. I know that in Linux setsid will fail
if the child has the same session_id as the parent. So on
Linux you must fork twice. But it also seems that the parent
must do an exit. And I don't want that. The code is not very
long - so I include it here.

gtk_text_view_get_iter_at_location
Hi, I'm having some problems and confusion. I am trying to truncate all text not visible in a GtkTextView but am getting very different results depending on if the text has any \n characters or not even if they all appear after where I would truncate. Here is the test case: http://pastebin.com/m27906ec3 The text I provide will full up 5 lines in the GtkTextView which is only 3 lines high. I try to truncate so that after loading, you will only have the first three lines and scrolling down ends after the third line. With the string that has a newline between the 4th and 5th wrapped lines it doesn't work. With the text that has no newlines, it works fine. I'm compiling like this: gcc test2.c -o test2 `pkg-config --cflags --libs gtk+-2.0` And run like this: ./test2 0 # For bad case where down arrow three times show text not truncated Or ./test2 1 # For good case where buffer is truncated to only what fits in viewable area Thanks in advance for any help. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Re: Forking from Gtk
G,
The basic design decision to use fork() as a way to do work in the
background flawed. fork()ing is not practical for gtk program. While
fork() has been a valid option for many non-gui programs in the absence
of threads, either g_thread_create() or pthread_create(). Today it is
not very useful -- as in stop doing it now!
Consider instead using a valid multi-threaded implementation like
g_threads_xxx() for GTK based programs. Or if full multi-threading is
not required, look at g_timeout_add() which is a background timer
routine that can serve as one or more background execution units; neatly
inside an gtk context.
$ devhelp
$ gtk-demo
The above two program you be pre-installed on your Linux machine:
devhelp has the gtk and glib api documentation, and gtk-demo shows you
many of the gtk/glib features in action.
Having said the multi-thread phrase, here is another word of caution.
In GTK only the main or ONE thread can safely interface with GTK api
calls that change the display. Using more than one thread to call gtk
apis at the same time will fail or cause a sigfault. The context of GTK
being your front-end to X11 is the source of this
none-thread-safe-caution; it is in how gtk MUST interact with X that
placing the multi-thread restriction. There are elegant work-arounds
this issue.
Here is a link to the classic FAQ answer on Multi-threaded GTK programs:
