Refresh Problem

[M Ezman Zainudin <ee4mez yahoo com>]

Hi,

I'm writing a GTK+ 2 program which reads some data
from a smart card. I am reading and subsequently
displaying the data in a GtkTextView, contained in a
GtkScrolledWindow, upon the click of a GtkButton.

The problem is, the GtkTextView is not updated until
the callback function returns. I have tried using
gdk_threads_enter() and gdk_threads_leave() in the
function but that still doesn't work.

I am currently using the following:-

  - GTK+ 2.2.1
  - gcc 3.2.2
  - RedHat Linux 9

The following is taken from the callback function:

  gdk_threads_enter();

  tbuf =
gtk_text_view_get_buffer(GTK_TEXT_VIEW(tview));
  gtk_text_buffer_set_text(tbuf, "new value", -1);

  csr = gdk_cursor_new(GDK_WATCH);
  gdk_window_set_cursor(GTK_WIDGET(btn)->window, csr);
  gdk_flush();

  gdk_threads_leave();


The code above changes the cursor, but does not change
the text in the GtkTextView. Please help.

Thanks
