Click a button without using mouse!!

Hi,

In my test case, I have two buttons(B1&B2), and I wish when I click B1,
then B2 will be clicked(do Activate callback of B2)!! I use PhEmit() to do
this job base on B2’s (x,y) coordinate, but it’s fault!! My App is dead
which looks like a deadlock!!

Could anyone help me!! thx !!
