GTK Textarea

[Tommo]

Hi, after a lot of searching, I found a textarea widget for GTK+. Alas, a sample program I tried to compile failed:

/*
 *File name: text.c
 */

#include <gtk/gtk.h>
#include <glib.h>

/*-- This function allows the program to exit properly when the window is closed --*/
gint destroyapp (GtkWidget *widget, gpointer gdata)
{
  g_print ("Quitting...\n");
  gtk_main_quit();
  return (FALSE);
}

int main (int argc, char *argv[])
{
  /*-- Declare the GTK Widgets used in the program --*/
  GtkWidget *window;
  GtkWidget *text;

  gchar *buffer = "This is some sample text";

  /*--  Initialize GTK --*/
  gtk_init (&argc, &argv);

  /*-- Create the new window --*/
  window = gtk_window_new(GTK_WINDOW_TOPLEVEL);

  /*-- Create a text area --*/
  text = gtk_text_new(NULL, NULL);

  /*-- Set text area to be editable --*/
  gtk_text_set_editable(GTK_TEXT (text), TRUE);

  /*-- Connect the window to the destroyapp function  --*/
  gtk_signal_connect(GTK_OBJECT(window), "delete_event", GTK_SIGNAL_FUNC(destroyapp), NULL);

  /*-- Add the text area to the window --*/
  gtk_container_add(GTK_CONTAINER(window), text);

  /*-- Add some text to the window --*/
  gtk_text_insert(GTK_TEXT(text), NULL, NULL, NULL, buffer, strlen(buffer));


  /*-- Set window border to zero so that text area takes up the whole window --*/
  gtk_container_border_width (GTK_CONTAINER (window), 0);

  /*-- Set the window to be 640 x 200 pixels --*/
  gtk_window_set_default_size (GTK_WINDOW(window), 640, 200);

  /*-- Set the window title --*/
  gtk_window_set_title(GTK_WINDOW (window), "Text Area");

  /*-- Display the widgets --*/
  gtk_widget_show(text);
  gtk_widget_show(window);

  /*-- Start the GTK event loop --*/
  gtk_main();

  /*-- Return 0 if exit is successful --*/
  return 0;
}

$ gcc test.c -o test `pkg-config --cflags --libs gtk+-2.0`
test.c: In function ‘main’:
test.c:32: warning: assignment makes pointer from integer without a cast
/tmp/ccoT6Lyf.o: In function `main':
test.c:(.text+0x74): undefined reference to `GTK_TEXT'
test.c:(.text+0x123): undefined reference to `GTK_TEXT'

I think the code is pretty old and gcc is having problems with gtk_text_new(NULL, NULL). I have seen code like this on the gtk website, and they use the same conventions. Any ideas?

It seems GtkText is deprecated. I have to use GtkTextView instead. Glad to see gtk.org is up to date though, that's really handy. Man, the lack of (up to date) GTK+ tutorials is rather annoying. Could be a project for the future if I manage to progress any further.
