[SOLVED] Error with setRect in QRect

[guidupas]

Hello all!

I have a QRect and when I try to setRect it return this error

/QT/Projetos/VisaoFinanceira/fluxocaixawidget.cpp:174: error: member function 'setRect' not viable: 'this' argument has type 'const QRect', but function is not marked const
fluxoRect.at(i).setRect(7,7,7,7);

Thanks.

Here is the code:
@
QList<QRect> fluxoRect;

fluxoRect.append(QRect(0,0,0,0));

fluxoRect.at(i).setRect(7,7,7,7);

Hey,

look at the definition of the at method:
const T & at(int i) const

QList returns a const reference to your QRect, hence you're not allowed to alter it.

You have to do something like this:
@ QList<QRect> fluxoRect;

fluxoRect.append(QRect(0,0,0,0));

QRect r = fluxoRect.takeAt(i);
r.setRect(7, 7, 7, 7);
fluxoRect.replace(i, r);@

Hi,

at is a constant function so you can't modify it's returned value like that.

Either use the value method or the [] operator.

You can also take the rect modify it and replace the original value with the new value.

Hope it helps
