Opening another created gui pyqt

[jaybstory]

Hello,

I would like to know how to open a gui after already having one gui open using pyqt? For example, I have a gui called popup and I want this gui to open another gui once I click the "ok" button. Would I need to use qprocess, qfile, or a some sort of signal slot connection to do this? Attached are the two guis I want to open. Runpopup2 is the first gui that I created and when the user clicks ok, I would like runabbs2 to open and runpopup2 to close. Thank you in advance.
