How to display whole QString while debugging

I am using Qtcreator and always when I need to display large string, it's trimmed, see screenshot: enter image description here

Is there any way to display whole QString? Note that using Open view contents in editor doesn't help either, it's same there.

Right-clicked on the "class Qstring" under "Value", then selected "Change value display format" -> "Treat all characters as printable"

None of the above change that a QString is displayed simply as an address, along with all its useless cryptic members.

However, if you right-click on the variable in the debugging panel, and click on "Use Debugging Helpers", all the contents of the string are displayed. Hoorah.

"In Local and Expressions, right click on the variable and click on Change Value Display Format, then under Change Display for type QString click on Separate Window"

Seems to be a limitation of the Qt Creator UI that cuts the displayed length of strings.

qDebug() << yourString; seems to work for me, I can see my whole string in the application output panel :-)

There is a setting under "Tools -> Options -> Debugger -> (Locals & Expressions or General (depending on your creator version))" that limits the string length to default 10000 characters.

You're right, I tried on my machine with a 150000 characters string and the same happened... It seems that qDebug() has the same limitation. I would suggest you to output your string to a file, using fstream for example.
