Re: Lower case to upper case german ess-zet
Thanks for your comments. I have entered the enclosed code in the begining and I get: Headers version: 2.12 Lib version: 2.12 I have compiled the code in GNU/Linux and in Windows XP with Mingw and I get the same version 2.12, and the same results. Which version do you have used? Best regards --- gchar *strLower = \xc3\x9f; //ß; printf(\nHeaders version: %d.%d, GLIB_MAJOR_VERSION, GLIB_MINOR_VERSION); printf(\nLib version: %d.%d, glib_major_version, glib_minor_version); --- 2007/9/11, David Nečas (Yeti) [EMAIL PROTECTED]: On Tue, Sep 11, 2007 at 06:12:53PM +, Luis Ramirez wrote: I have a problem converting german ess-zet (ß) from lower to uppercase when using g_unichar_toupper, but it works fine using g_utf8_strup.

Lower case to upper case german ess-zet
Hi
I have a problem converting german ess-zet (ß) from lower to uppercase
when using g_unichar_toupper, but it works fine using g_utf8_strup.
Using g_unichar_toupper I get a 0 as result.
Here it is a sample. The output is:
g_unichar_toupper. Lower:'ß', Upper:''
g_utf8_strup. Lower:'ß', Upper:'SS'
int main()
{
gchar *strLower = ß;
// Bad conversion with g_unichar_toupper
gunichar uniLower = g_utf8_get_char(strLower);
gunichar uniUpper = g_unichar_toupper(uniLower);
gchar strUpper[6];
gint len = g_unichar_to_utf8(uniUpper, strUpper);
strUpper[len] = '\0';
printf(\ng_unichar_toupper. Lower:'%s', Upper:'%s', strLower,
strUpper);
// Result: g_unichar_toupper. Lower:'ß', Upper:''
//Good conversion with g_utf8_strup
gchar *goodUpper = g_utf8_strup (strLower, -1);
printf(\nGood. Lower:'%s', Upper:'%s', strLower, goodUpper);
g_free(goodUpper);
// Result: g_utf8_strup. Lower:'ß', Upper:'SS'
}

Re: Image process in gdk
Problem solved! : As I viewed first time an image with gtk_image_new_from_pixbuf, when I tried to change that image later after pushing a button, nothing happened, but by using gtk_image_set_from_pixbuf instead, the image changes to the new one (no need to use expose_event at all) Thank you 2007/5/23, Luis Ramirez [EMAIL PROTECTED]: Thank you all!. I will try to re-read the Gtk docs following your advice and I will look for theScribble sample.
