Breakpoint with QString Condition in QtCreator

yeckel

Hi, is there a way how to set up more complex condition for breakpoint in QtCreator? At least comparing the QStrings. Integer comparsion like in tutorials works fine, but how about:

void foo(QString bar){
 qDebug() << bar;
}

breakpoint on qDebug line and condition:
bar == "BAR", or bar.equals("BAR")

Is it possible, or just basic data types are available? If so, how?

Thanks

Hi,
Bump with same question.

Hi,

Can you elaborate on this? What is it you want exactly?

I think I have the same problem. The condition does not seem to be evaluated. I have something like this in the condition field of my breakpoint:

qstringVar.compare("some value") == 0

However, the breakpoint is hit every iteration on that line although the qstringVar is not equal to the "some value". Why is that?

I got the same problem with a std::string. For instance using tmp.compare("some-value") == 0 with tmp being a std::string in the condition field does not work, i.e., the program stops whenever the breakpoint is reached even if the condition is not true.

Is this a bug? I am using QtCreator 4.5.0.
