Accessing the same variable from multiple windows.

[harvey_slash]

I want to access the same variable from mainWindow as well as my dialog class called 'Dialog'
suppose i change this variable from mainwindow, the change should be reflected whenever i use the variable from dialog.
i cannot use signal /slots due to some reasons.

i have already tried this.
i made a source calls vars.h /vars.cpp and declared the variable there, but it doesn't seem to work .
what can i do ?

Do you mean you need a global variable ?
Wouldnt go for a global variable since its not a good practice.
What are the reasons behind not using signals and slots ?
