comboBox with Qt::Alignement as itemData

HappyCoder

Hi,

i have a comboBox filled like this:

ui->comboBoxPos->addItem( "Top Left", (int)(Qt::AlignTop | Qt::AlignLeft) );
ui->comboBoxPos->addItem( "Top Centered", (int)(Qt::AlignTop | Qt::AlignHCenter) );
ui->comboBoxPos->addItem( "Top Right", (int)(Qt::AlignTop | Qt::AlignRight) );

or this

ui->comboBoxPos->addItem( "Top Left", 33 );
ui->comboBoxPos->addItem( "Top Centered", 36 );
ui->comboBoxPos->addItem( "Top Right", 34 );

With

void MainWindow::on_comboBoxPos_currentIndexChanged(int index)
{
qDebug() << Q_FUNC_INFO << ui->comboBoxPos->itemData(index).toInt();
}

I never get back the itemData? What i'm doing wrong?
Thx

Do you get the proper text (e.g. "Top Left") back?

yes, if i use the signal currentIndexChanged(QString). But i thought that for the first index (int)(Qt::AlignTop | Qt::AlignLeft) is the
data to that item and is stored as QVariant. I think i will make a switch case on the index, that is working.

i found a solution:

fill comBox with QStringList _PlotAlignMents and QList<qint32> _PlotAlignmentsData:

_PlotAlignments << tr("Top Left")       << tr("Top Centered")       << tr("Top Right")
                << tr("Centered Left")  << tr("Centered Centered")  << tr("Centered Right")
                << tr("Bottom Left")    << tr("Bottom Centered")    << tr("Bottom Right");
ui->comboBoxAlignment->addItems( _PlotAlignments );
_PlotAlignmentsData << (int)(Qt::AlignTop | Qt::AlignLeft)
                    << (int)(Qt::AlignTop | Qt::AlignHCenter)
                    << (int)(Qt::AlignTop | Qt::AlignRight)
                    << (int)(Qt::AlignVCenter | Qt::AlignLeft)
                    << (int)(Qt::AlignVCenter | Qt::AlignHCenter)
                    << (int)(Qt::AlignVCenter | Qt::AlignRight)
                    << (int)(Qt::AlignBottom | Qt::AlignLeft)
                    << (int)(Qt::AlignBottom | Qt::AlignHCenter)
                    << (int)(Qt::AlignBottom | Qt::AlignRight);
for(int i=0; i<_PlotAlignmentsData.size(); i++)
    ui->comboBoxAlignment->setItemData(i,_PlotAlignmentsData[i]);

now i can get the data:

void ui_plot_settings::on_comboBoxAlignment_currentIndexChanged(int index)
{
qDebug() << Q_FUNC_INFO << ui->comboBoxAlignment->itemData(index).toInt();
}

This works now.
