Hi,

The drop down from QComboBox is a QAbstractItemView which inherits from QAbstractScrollArea. You can try to apply flickcharm on it.

Hope it helps

Although the original posting was deleted and nobody knows what the exact problem was or what the opener already tried, this solution worked for me:

QScroller::grabGesture(ui->combo->view()->viewport(),QScroller::LeftMouseButtonGesture);

The scrollarea of the combobox can be scrolled with one finger on touch devices or using a touchpad/mouse with leftclick+mousemove

Thank you @the_ it's work fine i know it's been a long time for this question but i hope i got answer

QScroller::grabGesture(ui->combo->view()->viewport(),QScroller::LeftMouseButtonGesture);

but it's very fast i mean if i have a comobox that contain for example 1000 number from 1 to 1000
it scroll very fast when i scroll down it get to the end if i want to scroll up it go to the first how can i move slowly i do that in QListWidget

ui->listWidget->setVerticalScrollMode(QAbstractItemView::ScrollPerPixel);

so i can move on all items in the list
it there any way to do it on QComboBox
Thank you
