I don't understand that sentence. Were you able to open the file with QFile
and confirm that the application can read it?

Well, in this code, you didn't call file.open().
Try just this:
QFile file("mainwindow.ui");
if (!file.open(QIODevice::ReadOnly | QIODevice::Text));
qWarning() << "Could not open the file" << file.errorString();
else
qDebug() << file.readLine(50);
Then just look at the output in the console, or the "output" panel in creator,
or whatever you are using. If you see the warning, you have the explanation
there. If you see garbage output instead of text, your file is not how it
should be. If you see something like the UI file contents (<?xml version="1.0"
encoding="UTF-8"?> for example), then the problem is in the code below. But at
least let's confirm this first.
