These are the errors I get
main.cpp: In function 'int qMain(int, char**)':
main.cpp:7: error: 'GoToCellDialog' is not a member of 'Ui'
main.cpp:7: error: expected ';' before 'ui'
main.cpp:9: error: 'ui' was not declared in this scope

Help !

Looks like you named it "dialog", not "GoToCellDialog" (notice the objectName property in Designer).
