how to associate a LineEdit with Save button?

[rookee]

Hello d_stranz, I realized that what you said is right regarding LineEdit, I don't need it again. Instead of lineedit and the push button, can i choose to have a check box in my form which can prompt to enter a filename to log the data to the file and save it with .csv extension when the check box is checked. If that is possible, could you please guide me on how to do it. I'm still working on what needs to go within the push button, as of now its just opening and closing the file.
