Qt Installer Framework: How to disable/enable Next button in script

[SafaAlfulaij]

Hello all.
I'm trying to define a condition on the path allowed for my application to be installed to,. I'm detecting the textChanged signal from TargetDirectoryLineEdit QLineEdit, and doing my condition there.
The issue is, whatever I use, I can't disable the "Next" button. Tried:
( var widget = gui.pageById(QInstaller.TargetDirectory);)
widget.complete = false; and
buttons.NextButton.disabled = false; and
widget.setComplete(false);
but nothing works (last isn't exposed to JS side).

Any ideas?

So the widget is the button? You should find the button and then call setEnabled(false) or button.enabled = false.

That's my guess, I can't test now :/
