QLabel word wrap mode

Question

I have a label that sometimes contain a long text with no spaces (path in the computer).

So word-wrap wraps it very weirdly.

Is there a way to make the word-wrap of the label break in the middle of the word or not only at white spaces?

Answer 1

This isn't elegant but does work...
So say header class has Private:

QLabel *thisLabel;
QString *pathName;
QString *pathNameClean;

and of course defining thisLabel some where. so it would be nice if it was this simple....

thisLabel->setWordWrap(true);

that's fine IF AND ONLY IF the word has break points (WHICH PATHS SHOULD AVOID)

SO keep your actual path in a separate string if you need it for QFile purposes later. Then manually define a character per line number, and insert the spaces into the string.... so we'll say 50 chars is a good width...

    pathNameClean = new QString(pathName);

    int c = pathName->length();

    if( c > 50)
    {
        for(int i = 1; i <= c/50; i++)
        {
            int n = i * 50;
            pathName->insert(n, " ");
        }
    }
    thisLabel->setText(pathName);

Shazam.... simulated WordWrap with no original spaces...

just remember that pathName string is now just for pretty QLabel purposes and that the pathNameClean string is the actual path. Qt programs will crash if you try to open a file with a space injected path.....

(if there's no simple class method it's likely just a few lines of code to do... and why problem solving is a programmers best tool!)

One way is to use the QTextOption class with a QTextDocument instead of a QLabel. This let you use QTextOption::WrapMode. QTextOption::WrapAtWordBoundaryOrAnywhere should do what you want.
