setWhatsThis on QComboBox

[Amrita_S]

Hi,
I was trying to use setWhatsThis function with QComboBox,its not working. But it is working with QLineEdit and other QWidgets. I have to implement it in Qt4.1.4 .

@Amrita_S
what are you trying to do ?Show me what you have tried?

[Amrita_S]

QComboBox *ddEOFMode;
ddEOFMode = new QComboBox(groupBox2_2);
ddEOFMode->addItem(QApplication::translate("fConfig", "added item1", 0, QApplication::UnicodeUTF8));
ddEOFMode->addItem(QApplication::translate("fConfig", "added item 2", 0, QApplication::UnicodeUTF8));
ddEOFMode->addItem(QApplication::translate("fConfig", "added item3", 0, QApplication::UnicodeUTF8));
ddEOFMode->setWhatsThis(QApplication::translate("fConfig", "whatsthis for ddeof", 0, QApplication::UnicodeUTF8));

@Amrita_S
Why not http://doc.qt.io/qt-4.8/qwidget.html#toolTip-prop ?

[Amrita_S]

I mentioned in my question that Qt4.1 not newer versions
and issue is that its not working specially for combo box

Do you want to set the what's this for the whole combobox or of an item of the combo list?

in the second case you can use http://doc.qt.io/qt-4.8/qcombobox.html#setItemData with Qt::WhatsThisRole as role

@VRonin Qt::ToolTipRole is working but WhatsThisRole is not working and My preference is what's this for whole combo box
