Create dynamic buttons with function

ppitu

Hi,

I have to dynamiclly create buttons in horizontalLayout and connect this buttons to my function.

I create button in this way:

for(auto & mTitle : pattern.mTitles)
    {
        ui->horizontalLayout->addWidget(new QPushButton(mTitle));
    }

How can I connect the function to this buttons?

I don't really understand your problem here.
Use the instance and connect the right signal to the wanted function.

For example, with a lambda function, I would do it like this:

for(auto & mTitle : pattern.mTitles)
{
    auto btn = new QPushButton (mTitle);
    connect (btn, & QPushButton :: clicked, this, [btn] () {
          qDebug() << "Button" << btn << "clicked"; 
    });
    ui->horizontalLayout->addWidget(btn );
}

Then you don't search very well, for example in the QObject:connect() documentation:
