Hello Austin and all,

I don't think that synthetizing key presses is the way to go. You can 
get a similar effect as is in the device lock screen  by setting your 
GTK_ENTRY's editable property to FALSE:

   myentry=gtk_entry_new();
   gtk_editable_set_editable(GTK_EDITABLE(myentry), FALSE);

Then use gtk_editable_set_text, gtk_editable_insert_text etc. to set to 
text in your text box according to your button presses.
