format stream output

[ODБOï]

hi
with this code

   qDebug()<< reMatch.captured(1)  << " : " << reMatch.captured(2)
                    << "; DIAM : " <<  reMatch.captured(3)
                    << "; LT : "  << reMatch.captured(4)
                    << "; LU : "  << reMatch.captured(5);

the output is

"T1"  :  "BOULE" ; DIAM :  "10" ; LT :  "111" ; LU :  "80"
"T2"  :  "CYL" ; DIAM :  "11" ; LT :  "112" ; LU :  "81"
"T3"  :  "DROIT" ; DIAM :  "12" ; LT :  "113" ; LU :  "82"
"T4"  :  "CON" ; DIAM :  "13" ; LT :  "114" ; LU :  "83"

how can i have an output where DIAM LT LU are correctly aligned ?

"T1"  :  "BOULE"; DIAM :  "10"; LT :  "111"; LU :  "80"
"T2"  :  "CYL";   DIAM :  "11"; LT :  "112"; LU :  "81"
"T3"  :  "DROIT"; DIAM :  "12"; LT :  "113"; LU :  "82"
"T4"  :  "CON";   DIAM :  "13"; LT :  "114"; LU :  "83"

use \t instead of spaces

Is your output going to somewhere with a fixed-width font, else it's going to be problematic?

Assuming it is, you can use @VRonin's \ts, or you pre-format the string with width specifiers (must be somewhere in QString) before passing to qDebug().

@VRonin thank you very much

        qDebug()<< reMatch.captured(1)
                    << ":"
                    << reMatch.captured(2) << "\t"
                    << "DIAM :"
                    <<  reMatch.captured(3)<<";"
                    << "LT :"
                    << reMatch.captured(4)<<";"
                    << "LU :"
                    << reMatch.captured(5)<<";";

@JonB said in format stream output:

width specifiers

i will take a look at that also thank you!

@LeLev
https://doc.qt.io/qt-5/qstring.html#arg is the overload you want for strings, use fieldWidth argument (negative number if you want left-aligned as per your example). Tabs are quick and work till they don't (depends on number of characters determining where the next tab stop is).
