deleting text in a text view
I'm probably using the wrong widget for this, but never-the-less. I have a GtkTextView in a window used for data entry into a database. The text typed in the view gets put in the database no problem, but once the data entry has occurred, I want to clear the view so that the next screen of data can be input. Looking through the API, there isn't a set text function for this view (per se) except in the GtkTextBuffer. The other funcition in that widget is gtk_text_buffer_delete, which I called but I'm getting an error. Here's the code I was using to get the buffer, then delete it: /* the GtkTextView in this window requires a bit of extra work to get the text value stored in it. */ specialView = lookup_widget(customers, cust_instructions); specialBuffer = gtk_text_view_get_buffer(GTK_TEXT_VIEW(specialView)); gtk_text_buffer_get_bounds(specialBuffer, start, end); gtk_text_buffer_delete(specialBuffer, start, end); But here's the error I'm getting when I try to do that: (dispatcher:1523): Gtk-WARNING **: Invalid text buffer iterator: either the iter ator is uninitialized, or the characters/pixbufs/widgets in the buffer have been modified since the iterator was created. You must use marks, character numbers, or line numbers to preserve a position ac ross buffer modifications. You can apply tags and insert marks without invalidating your iterators, but any mutation that affects 'indexable' buffer contents (contents that can be referred to by character offset) will invalidate all outstanding iterators (dispatcher:1523): Gtk-CRITICAL **: file gtktextbuffer.c: line 1297 (gtk_text_bu ffer_delete): assertion `gtk_text_iter_get_buffer (start) == buffer' failed Then it segfaults. So I tried the set text call like this: gtk_text_buffer_set_text(specialBuffer,, 0); but I think that makes my app segfault as well. Can anyone help? -- .''`. Carl B.

Re: glib 2.2.3 compile failure
On 2003-11-23, I wrote I'm trying to compile glib 2.2.3 on HP-UX 11.11. The compile fails in glib/libcharset with this error: /bin/sh ../../libtool --mode=link gcc -g -O2 -Wall -Wl,+s \ -L/home/e/l/ellement/usr/lib -o libcharset.la localcharset.lo -lintl false cru .libs/libcharset.a .libs/localcharset.o make[3]: *** [libcharset.la] Error 1 What is the cause of this error? How do I correct it? It turns out configure didn't find 'ar', and used 'false' instead. Once I re-ran configure with AR=ar, everything compiled. (For some reason, configure doesn't find a number of tools in my path: gcc, ar, awk, sed, ld, and pkg-config. With other packages, their configure finds things that are in my path). I didn't actually figure this out myself. I found a discussion of my original problem on the cURL mailing list archive after searching for false cru. -- David Ellement ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list

Re: [Fwd: Re: Still have pb installing gtk+2.2]
Ok, actually... I should look at the MINOR MAJOR lines Ok, i have the 0.2 version of render.. about xrender, i still don't know... I think I shoul install them anyway.
