Hi All,

i'm tring to connect 2 widget but i havo problems to know how to do it.

i can reproduce my problem with an example :

W-1 (spinbox + button)   [ it is a main app, and has in the menu bar  
an action to open W-2]

W-2 (line edit + button)

i run W-1, pressing its button it increase the spinbox value,
then pressing the action from the menu -> open W-2

W-2 , at its start, read value from W-1 -- pressing the W-2 button  
process W-1 value and print it .

my problem :
