是放在回调函数中insert吗？
我运行了但是不能加进去，能帮我看看程序吗？
#include <locale.h>
#include <gtk/gtk.h>


void enter_callback(GtkWidget *widget, GtkWidget *entry,GtkWidget *text, gchar *addtext)
{
gchar *entry_text;
entry_text = gtk_entry_get_text(GTK_ENTRY(entry));
gtk_text_insert(GTK_TEXT (text), NULL, NULL, NULL,"Supports ", -1);
printf("Entry contents: %s\n", entry_text);
}

int main (int argc, char *argv[])
{

    GtkWidget *window;
    GtkWidget *vbox, *hbox, *box1;
    GtkWidget *entry;
    GtkWidget *button;
    GtkWidget *check;
    GtkWidget *clist;
    GtkWidget *text;
    GtkWidget *vscrollbar;
    GtkWidget *table;
    gchar *titles[1] = {"NAME"};
    gchar *name[1]={"tom"};
    gchar *addtext="123";


    gtk_set_locale();
    gtk_rc_add_default_file("./gtkrc.zh");
    gtk_init (&argc, &argv);

    /* create a new window */
    window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    gtk_widget_set_usize( GTK_WIDGET (window), 500, 500);
    gtk_window_set_title(GTK_WINDOW (window), "GTK Entry");
    gtk_signal_connect(GTK_OBJECT (window), "delete_event",
                       (GtkSignalFunc) gtk_exit, NULL);

    vbox = gtk_vbox_new (FALSE, 0);
    gtk_container_add (GTK_CONTAINER (window), vbox);
    gtk_widget_show (vbox);

    hbox = gtk_hbox_new (FALSE, 0);
    gtk_container_add (GTK_CONTAINER (vbox), hbox);
    gtk_widget_show (hbox);   

    table = gtk_table_new (2, 2, FALSE);
    gtk_table_set_row_spacing (GTK_TABLE (table), 0, 2);
    gtk_table_set_col_spacing (GTK_TABLE (table), 0, 2);
    gtk_box_pack_start (GTK_BOX (hbox), table, TRUE, TRUE, 0);
    gtk_widget_show (table);

回调函数不是这样写的.
[code:1]
void enter_callback(GtkWidget *widget, void * data)
{
gchar *entry_text;
entry_text = gtk_entry_get_text(GTK_ENTRY(widget));
gtk_text_insert(GTK_TEXT (text), NULL, NULL, NULL,entry_text, -1);
}
[/code:1]
gtk_signal_connect(GTK_OBJECT(entry), "activate",GTK_SIGNAL_FUNC(enter_callback),entry) ; 最后一个参数也有问题,那个参数是传递指针用的,虽然你现在写的语法上没有错误,但不知道你有没有理解这个参数的用途.
另外把GtkWidget *text设为全局变量或者通过上面提到的指针传递过去.
