Split a String at prompt "."

[meikelneit]

I just hitted my dot button :P, how do i know if its a char or a string? Shall i use the Hexcode of the Ascii?

ps: yes ";" is no Problem. Try it with "."

@meikelneit
I hope I understand your problem, my English isn't good :(
Anyway, It works well with "."

how do i know if its a char or a string?

"." -> implicit QString
'.' -> implicit QChar

QString(".");
QChar('.');

' more than 1 character' -> Compiler error.

this works well in my code:

Are you trying to split an ; ?

Try it with "."

Split works both with string and char as split has overloads with string and char .

I just can tell u what happens when i try to split with ".".

the line i tryed to split is: Array[0..3] of Int;

when i use "." is QRegularexpression to split with, i get 21 List Elements and every single one is empty.
it wokrs without error, but pls have a look into your listelements, mine were empty, and i had 21 of them, i expected 3.

@meikelneit Can you show your code including the exact string you're trying to split?

The second argument to split takes care of this: https://doc.qt.io/qt-5/qstring.html#split-3

@Ratzz

Split function works well in both cases:

• QStringList list = text.slit(".");
• QStringList list = text.split(";");

If it is what you want to know, be patient if I didn't well understand

Also I tried:

• QStringList list = text.slit(‘.’);
• QStringList list = text.split(‘;’);

Also in this cases split works well.

Hi

(QRegularExpression(".")

The dot in regular expressions means any character. As you discovered, if you want to express a literal dot you have to escape it.

You can test your expressions with the QRegularExpression example tool.

Thank you very mutch, that explains why i have 21 empty listelements. It just splits between every single character. :) ok thx
