passing data from forms

**shreeram** · 16th March 2015, 18:14

Hello everybody, I am very new to Qt.. I have a QWidget which is my main form. In it, if a radio button is clicked, a pop up window appears, which is a separate QDialog I added as a 2nd form. Till this, it is fine.. Now there are line edits in the 2nd form which the user fills.. I want the data to be used in the 1st form. How to go about it?

P.S I hope I am clear.
and thanks for your time

Regards
Shree

That depends on how you are using the dialog.
If this is a modal dialog, i.e. one that you display using exec(), then simply add getter functions and call them after exec() to retrieve the values.

If it is a non-modal dialog, i.e. one that you display using show(), then add signals that are emitted then the values change or a signal that emits all the values when the dialog is closed.

Cheers,

I am sorry... I tried googling what getter function is.. I am just not able to understand.. I use modal dialog box. It would be great if you could explain with an example code..
Thanks
