QIcon setting and icon then getting name of existing set icon

SPlatten

I am setting icons in a QComboBox, the icons are created with:

mpicnConnected = new QIcon(":/ICN_CONNTD");
mpicnNotConnected = new QIcon(":/ICN_DISCONTD");

I set the icons in the combo using the setItemIcon function, this all works, what I want to do is determine what the existing icon is from the selected item in the combo, I get the icon with:

int intIndex(mpcboTraineeToView->findText(crstrHostname));
if ( intIndex == -1 ) {
    return;
}
QIcon currentIcon(mpcboTraineeToView->itemIcon(intIdex));

currentIcon does return an object, but the name function returns an emtpy string, how can I determine what icon has been set which can only be either: mpicnConnected or ** mpicnNotConnected**

You should not abuse pointers, it is enough to use:

QIcon mpicnConnected(":/ICN_CONNTD");
mpcboTraineeToView->setItemIcon(index, mpicnConnected);

Read abour memory-leak

There is no way to do that but an alternative is to use userData to store the name:

QIcon mpicnConnected(":/ICN_CONNTD");
mpcboTraineeToView->setItemIcon(index, mpicnConnected);
mpcboTraineeToView->setItemData(index, ":/ICN_CONNTD");

Then

int intIndex(mpcboTraineeToView->findText(crstrHostname));
if ( intIndex == -1 ) {
    return;
}
QString data = mpcboTraineeToView->itemData(index).toString();
qDebug() << data;

Hi
I dont think you can get the name from the icon constructed as you have shown.

Thank You

@SPlatten

If others didn't work then try using QMap


QMap<QString,QString> icons;
 // first one for text or item no and second for path
icons.insert("first selection", ":/ICN_CONNTD");
icons.insert("second selection", ":/SECOND");


// and on selection change you can simply get the icon using 
selectionChanged(QString text){
QString iconName = icons.value(text);
// Here you can access the icon name

}

I don't think as good answer but it can get work done. LOL

Thanks
