In Q creator how can i compare listwidget index 1 string with string?

[jsulm]

@Maddy Do you mean in Qt? QtCreator is an IDE.

if (listWidget->item(1)->text() == someString)

[Maddy]

Yes in IDE .main.cpp:56:33: Result of comparison against a string literal is unspecified (use an explicit string comparison function instead) his error is coming

Don't you think you should post the code which causes this error?

"Yes in IDE" - your question has nothing to do with the IDE...

[Maddy]

I don't know what this means.
Please explain better...

in listwidget i want to show item and randomword. how can i do?

Hi,

Extract the items in a list, shuffle that list and re-insert the items.

Another way is to use a QListView with a QStringListModel. Shuffle your string list and apply it to the model once done.

How to show random word listwidget using additems?

[JonB]

@Maddy

• Pick a random word and pass it to void QListWidget::addItem(const QString &label)..
• Or, pick a number of random words, put them in a QStringList and pass that to void QListWidget::addItems(const QStringList &labels).

How to pick random word? that what I require to do.

[JonB]

@Maddy

• Get/choose your source with words in it. I do not know what you intend to do for that.
• Assuming they are in some vector/array. Generate a random integer (Qt has QRandomGenerator Class) between 0 and 1 less than the count of words.
• Pick that word via vect[random_int].

i have made qstring fonts then int x as qrandom generator.following is showing an error required ')'.
ui->listWidget_2->addItems("Task 1(RandomWord):" fonts(x));

"Task 1(RandomWord):" fonts(x)

is not a legal expression in C++.

Please read documentation and learn how to create strings (https://doc.qt.io/qt-6/qstring.html). Also, learn C++.
And please explain what exactly "fonts" is.

[Maddy]

the fonts is qstringlist from which i want to display strings

is the answer. If you already have a QStringList ("the fonts is qstringlist ") then pass that to addItems().

Your earlier

ui->listWidget_2->addItems("Task 1(RandomWord):" fonts(x));

passes "Task 1(RandomWord):" fonts(x), which is neither a legal C++ expression, nor if it were would it be a list (QStringList), which is what you say you want to pass and what addItems() accepts. If you say you want to add a list and are going to call addItems() then there is not much point trying to pass it something like a single item....
