How do i add an icon to QComboBox in Qt?
You can simply do (Qt5), for example:
QIcon icon = QIcon::fromTheme("edit-undo");
QString label = "foo";
combo->addItem( icon, label );
Update: based on Qt 5.13 (released 2019) there us a dedicated API for this:
void QComboBox::addItem(const QIcon &icon, const QString &text)
Or if you want to specify an index:
void QComboBox::insertItem ( int index, const QString & text)
void QComboBox::setItemIcon ( int index, const QIcon & icon )
All credit for this update goe to user Soyal7 who suggested the edit. The former response, which still applies especially for older versions, was:
You can use the following APIs:
void QComboBox::insertItem ( int index, const QString & text, const QVariant & userData = QVariant() )
void QComboBox::setItemIcon ( int index, const QIcon & icon )
http://doc.qt.io/qt-5/qcombobox.html#insertItem
http://doc.qt.io/qt-5/qcombobox.html#setItemIcon
As for the code snippet it's as easy as this:
void AddItem(QComboBox* combo, QString itemName, QIcon* icon)
{
combo->insertItem(0, itemName);
combo->setItemIcon(0, *icon);
}
