Detailed Description

A way to ask a user a question from inside a GUI-less library (like KNewStuffCore)

Rather than using a message box (which is a UI thing), when you want to ask your user a question, create an instance of this class and use that instead. The consuming library (in most cases KNewStuff or KNewStuffQuick) will listen to any question being asked, and act appropriately (that is, KNewStuff will show a dialog with an appropriate dialog box, and KNewStuffQuick will either request a question be asked if the developer is using the plugin directly, or ask the question using an appropriate method for Qt Quick based applications)

The following is an example of a question asking the user to select an item from a list.

QStringList choices() << "foo" << "bar";
Question question(Question::SelectFromListQuestion);
question.setTitle("Pick your option");
question.setQuestion("Please select which option you would like");
question.setList(choices);
question.setEntry(entry);
if (question.ask() == Question::OKResponse) {
    QString theChoice = question.response();
}

setResponse() [1/2]

void Question::setResponse

(

const QString &

response

)

If the user has any way of inputting data to go along with the response above, consider this a part of the response.

As such, you can set, and later get, that response as well. This does NOT mark the question as answered (

See also

setResponse(Response) ).

Parameters

response

This sets the string response for the question

Definition at line 102 of file question.cpp.

setResponse() [2/2]

void Question::setResponse

(

Response

response

)

When the user makes a choice on a question, that is a response.

This is the return value in ask().

Parameters

response

This will set the response, and mark the question as answered
