How to allow user to configure keyboard shortcuts?

[kitfox]

I'm developing an app with a lot of commands and would like to provide the user with a mechanism to customize the keyboard shortcuts.

I'm having a hard time coming up with any solution that I would call elegant, since all my attempts so far require me to create a new class for each individual action I want to make available (Ie, I'm using ActionInfo to provide info about an action a user can configure, and subclassing ActionRunnable for each different action the user can take):

class ActionInfo : QObject
{
    Q_OBJECT

    QString _id;
    QString _name;
    ActionRunnable* _runnable;
    QPointer<QAction> _action;
...
}

I might be able to replace the _runnable with data I could use to indicate a slot, but I don't know the datatype I should use for this.

Does Qt provide some sort of mechanism to make user configurable shortcuts easier? Any examples of this would be a big help.

Just a question. How do you provide mechanism for the user to define the keyboard shorts cuts ? Is it through some configuration file or user enters it ?

@dheerendra I haven't written it yet, but I was thinking that the user could open a dialog box that shows a spreadsheet with two columns - names or ids of commands on the left and shortcuts on the right. I'd also consider using an XML file that maps command id names to keyboard shortcuts.

You can use QKeyShort cut and make it happen. It could be some thing like follows.

void MyWidgetShortCuts::on_pushButton_clicked()
{
    QString text = this->ui->lineEdit->text();
    QShortcut *shortKey = new QShortcut(QKeySequence(text),this);
    connect(shortKey,SIGNAL(activated()),this,SLOT(callMe()));
}

text is keyboard short cut. You can define your own slot.
