Use the method text() for QLineEdit.
Also why are you doing the initializations in main.cpp and not in the class constructor??

With lineedit.text() I'm getting only the , latest lineedit's value.
but im using two lineedits.
how can i access both?

im using in main because,
i want to create dynamic line edits frm database
the folowing code will be replaced..
where q is the sqlquery with attributes for creating LINE EDIT.

OLD CODE:
w->createLineEdit("","NameLineEdit",1,1);

NEW CODE:
w->createLineEdit(q.value(1).toString(),q.value(1).t oString(),1,1);

HOW CAN I ACCESS ALL THE LINEEDITS VALUE?

Don't shout; it's rude.

Read something about C++ programming and how to store values and keep references.

In class DynamicControls: give every line edit an id, and create a getter function ala return getLineDcit(id)->text();.
