Connect a checkbox widget to a line edit to appear when toggled box

[AXNT]

Using QT Creator
I created a checkBox named advSearch and when it is toggled, I want a lineEdit box named rmaEdit to appear.
However, when I try to do ui-> advSearch, it says that
error: no member named 'advSearch' in 'Ui::MainWindow'
However, the rmaEdit appears.

@AXNT

Can you clean and rebuild solution ?
When you type ui-> does be any suggestion for advsearch Checkbox?
can you check if advsearch is missspelled?
also can you show contents of mainwindow.ui?

@AXNT and when you're back from solving "error: no member named ..." you may want to take a look at your method on_advSearch_toggled()

1. ui->advSearch->setCheckable(true) for sure had happened before (hopefully in the auto-generated UI code because you checked "checkable" property for the QCheckBox widget when you placed it in the UI. No need to do that there.
2. No need to connect(...) any signal from QCheckBox object to QLineEdit object.
   Just do (pseudo-code):

ui->rmaEdit->setVisible(checked);

this way when the on_advSearch_toggled() method is called because the user checked or unchecked the box, the QLineEdit widget will be visible (checked is true) or not visible (checked is false)

PS: next time, please don't paste an image of your code, just surround it with the code tag (icon </>) to get something like this, that you'll fill out with your code snippet...
