How disable all QLineEdit
Message 1 in thread
Hi
How can I do to disable all objects of type QLineEdit at once without using setEnabled for each object? This is possible?
Thanks,
Marcelo E. Geyer

if you want to avoid code like:
useredit->setEnabled(false);
passedit->setEnabled(false);
... (and so forth for every line edit you have in your widget)
you can instead iterate through all the line edits in your widget like this:
QList<QLineEdit*> all_lineedit = findChildren<QLineEdit*>();
forach(QLineEdit* p_lineedit, all_lineedit)
p_lineedit->setEnabled(false);
Cheers,
Peter

Hi
If they had a common parent you could just disable the parent.

Why *not* use setEnabled on each object?
Get a list of QLineEdit with QObject::findChildren and then iterate through it.
