我正在开发一个应用程序,当单击按钮时,该应用程序具有数字小键盘和文本框,文本框显示该数字.我需要为每个按钮编写一个函数吗？或者您可以将文本和小部件作为参数传递？

#include <stdio.h>
#include <stdlib.h>
#include <gtk/gtk.h>

void callback( GtkWidget *widget,
               gpointer   data )
{
   gtk_entry_append_text(entry, text);
}

void create_button(GtkWidget* table,GtkWidget* entry,
                    int start_r,int end_r,

{
    GtkWidget *button;

    button = gtk_button_new_with_label (label);
    g_object_set_data( G_OBJECT( button ),
                           "char", (gpointer)label );
    g_signal_connect (button, "clicked",
              G_CALLBACK (callback), entry);

    gtk_table_attach_defaults (GTK_TABLE(table), button, start_c, end_c, start_r, end_r);

    gtk_widget_show (button);

}

gint delete_event( GtkWidget *widget,
                   GdkEvent  *event,
                   gpointer   data )
{
    gtk_main_quit ();
    return(FALSE);
}

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

    GtkWidget *window; …
