Pick words from .txt
-
Hola! How I can import words from file called test.txt? For example I want import words "a dog", " a cat", "a car" and "a boy". Words are separated from other files with %% or with anything sign, because I want they individually. @a dog %% a cat %% a car %% a boy@
Do you understand? If you don't, I can explain.
Thank you! -
You can use QTextStream, QTextStrem::readLine() and QString::split().
-
Could you write example how to use those. I'm beginner, so I don't understand yet everything in the docs.
-
May be you should try reading the doc again. Example is already given "there":http://doc.qt.nokia.com/latest/qstring.html#split
bq. QString str = "a,,b,c";
QStringList list1 = str.split(",");
// list1: [ "a", "", "b", "c" ] -
Ok. Now I can split them, but still, how I can use them alone?
-
What do you mean by use them alone?
QStringList is a list with strings. You can access each item seperatly. -
you may use "at()":http://doc.qt.nokia.com/stable/qlist.html#, first(), last()... etc
-
I mean that I want add each of them one at time to listWidget when I click pushButton.
@char* word1 = first // first should be" a dog"
char* word2 = second // second should be "a cat"
static int Time = 1;
if (Time == 1)
{
ui->listWidget->addItem(word1)
}
if (Time == 2)
{
ui->listWidget->addItem(word2)
}
Time == Time + 1;@
Do you understand now? -
@QString str = " a dog %% a cat %% a car %% a boy";
QStringList list1 = str.split("%%");for (int i = 0; i < list1.size(); ++i)
ui->listWidget->addItem(list1.at(i));@Note : just wrote roughly here, not tested. :)
OR if you want to add one item per click,
in the slot for button,
@static int i = 0;
if(i < list1.size())
ui->listWidget->addItem(list1.at(i));
i++;@ -
Thanks! I was just stupid and I didn't understand how I must use "list1.at(i)" command. Now I can make my application! THANK YOU!

bq. There are no stupid questions, only stupid answers.
Go ahead :) Happy coding :)
