QString::mid question

RIVOPICO

Hi i checked all but one thing i never can get is for example i have this string.
QString string= "change"
"abcde"+ string + "ijklm"
Sometimes the length of my string change. How i can start counting since right and get complet string for example i start since letter k so i will get:
"abcde"+ change + "ijk"

Sorry if i was explaining bad but i want to count since right with mid. thx

Hi,

Do you mean get the length length of "ijk" or get the length of "abcde" + some_string + "ijk" ?

RIVOPICO

@SGaist said in QString::mid question:

"abcde" + some_string + "ijk"

"abcde" + some_string + "ijk" if the some_string change each time the length.

This will return the number of code points of the combined string:

QString("%1%2%3").arg(first_string).arg(second_string).arg(third_string).size()

I think what @RIVOPICO is trying to say (I could be completely wrong), is:

he already has a string like abcdesome_stringijklm
he wants to use QString::mid() to extract just some_string, but of course, QString::mid() requires a substring lengh, which is unknown in this case.

If I read @RIVOPICO correctly, then he could do something like: string.mid(6, string.length()-11); ?
