Yes, it returns NULL if the cast failed.

As for the type, this might also work:

QObject *obj = widget; objType = obj->metaObject()->className(); if (objType == "QPlainTextEdit") { QPlainTextEdit *textEdit = qobject_cast<QPlainTextEdit*>(obj); //do something }

Never tried it though. If it works, you won't have to make multiple casts.
But you will still have to check which className it has.

Could not find anything.

I solve it I use the same thing

ui->comboBox->view()->setVerticalScrollMode(QAbstractItemView::ScrollPerPixel);

if there is a better solution please post it
Thanks

@SGaist Thanks Champion! I will try !

@SGaist That's pretty close to what I like to achieve. Unfortunately I am using a QML TableView. The only difference to the FrozenColumnExample is that my Frozen Rows have a dynamic count. A binary role in my table model determines to which section the entry belongs to. I will try to adapt the FrozenColumnExample to my case in QML. That was my idea anyway, but I was hoping for more simple solution ;) Substituting the sections with seperate TableViews and using a QSortFilterProxyModel to simulate the section behavior is the way to go I guess. Thx for your tip.

Hi and welcome
I think you might need to set margin for inner area
The following works for me with 32x32 images for the ends

/*inner area*/ QScrollBar::vertical { border: 1px solid #a5a5a5; background: none; width: 65px; margin: 42px 0 42px 0; /* match top/lower area*/ } /*the knob*/ QScrollBar::handle:vertical { background: #d5d5d5;; border: 2px solid #000000; min-height: 60px; border-radius: 12px; } /*lower arrow area*/ QScrollBar::add-line:vertical { border: 0px solid grey; background: NONE; height: 40px; subcontrol-position: bottom; subcontrol-origin: margin; } /*top arrow area*/ QScrollBar::sub-line:vertical { border: 0px solid grey; background: none; height: 40px; subcontrol-position: top; subcontrol-origin: margin; } /*arrows*/ QScrollBar::up-arrow:vertical { image: url(:/GFX/sbar/up_arrow_scrollbar.png); } /*pressed*/ QScrollBar::up-arrow:vertical::pressed { image: url(:/GFX/sbar/up_arrow_scrollbar_pressed.png); } QScrollBar::down-arrow:vertical::pressed { image: url(:/GFX/sbar/down_arrow_scrollbar_pressed.png); } QScrollBar::down-arrow:vertical { /* border: 2px solid grey; width: 3px; height: 23px; */ image: url(:/GFX/sbar/down_arrow_scrollbar.png); } QScrollBar::add-page:vertical, QScrollBar::sub-page:vertical { background: none; }

Hi,

The focus changed when you clicked the button. What you can do is to keep track on the currently focused QLineEdit in a member variable so you can use it at deletion time. Or you could add a remove button besides your QLineEdit and use that to remove them.
