Retrieving and converting values

[jcoop]

Say I've got a QLineEdit and I need to retrieve the text, then convert it to a float for processing. How would I do that? The ways I've been trying so far always end up throwing compilation errors.

[wysota]

QLineEdit::text() and QString::toDouble()

or

QDoubleSpinBox

So would that be something like:

double d = myLineEditName->text()->toDouble();

It's the syntax that I'm not getting.

double d = myLineEdit->text().toDouble();
try breaking the operation sequence into series of steps...syntax evolves itself!

cheers!
