Help: GdkEventKey callback

[Cuong Tran <cuong h tran att net>]

Hi,

I tried to register a callback for key_release_event associated with a
text widget using gtk_signal_connect().  But it did not seem to work.  I
am using GTK 1.2.

The code is below.  Any suggestions?

Thanks,
Mike Tran

/*

#include <gtk/gtk.h>
#include <gdk/gdkkeysyms.h>

static GtkWidget *textarea;
static gint key_release_callback(GtkWidget *widget, GdkEventKey *event,
gpointer data );

void CreateTextArea(GtkWidget *window, GtkWidget *container)
{
    GtkWidget *table;
    GtkWidget *hscrollbar;
    GtkWidget *vscrollbar;
    GdkFont   *textfont;
    GtkStyle  *style;


    /* create a table to put text widget and scrollbars */
    table = gtk_table_new(2, 2, FALSE);

    /* no gaps between scrollbars and the text */
    gtk_table_set_row_spacing( GTK_TABLE(table), 0, 2);
    gtk_table_set_col_spacing( GTK_TABLE(table), 0, 2);
    gtk_container_add(GTK_CONTAINER(container), table);

    /* create text area */
    textarea = gtk_text_new(NULL, NULL);
    gtk_signal_connect(GTK_OBJEC(textarea),"key_release_event",
        GTK_SIGNAL_FUNC(key_release_callback), ULL);

        /* +++ other stuffs +++ */
}

static guint last_keyval = 0;

static gint key_release_callback(GtkWidget *widget, GdkEventKey *event,
gpointer data )
{
    last_keyval = event->keyval;

#ifdef DEBUG
    g_print("lastkey=%x\n", last_keyval);
#endif
    /* will do something eventually */

    return FALSE; /* to other handlers */
}
