confused about Qt designer 4.3

[rishiraj]

Hi everyone,
I am completely new to Qt.
I am trying to use Qt designer 4.3 .....I created a small dialog containing an edit box and a push button and the plan was that in the final product when I click on the 'push button' a message 'Hi' should be displayed in the edit box.
I made a new slot by the name display() and made the needed connection.... but now the problem is,I can't seem to find where to write the code for the display() slot (which should contain that code to display the 'Hi' in the edit box)..I hope someone will be guide me on this.If possible,I would appreciate screenshots of the procedure...Thanks in advance guys..do help me on this.
