Don't you have access to the source code ?
And if not, ask the authors ?

@jeanmilost
Your logic seems to be correct.
What you have to do is to move the re-calculation of Scrollbar size & position to the Rectangle rcPageContainer because you are applying scale for that.

Rectangle { id: rcPageContainer objectName: "rcPageContainer" ... /// called when page viewport width changed onWidthChanged: { sbHorz.size = rcPageViewport.width / rcPageContainer.width sbHorz.position = Math.min(Math.max(sbHorz.position, 0.0), 1.0 - (sbHorz.size)); } /// called when page viewport height changed onHeightChanged: { sbVert.size = rcPageViewport.height / rcPageContainer.height sbVert.position = Math.min(Math.max(sbVert.position, 0.0), 1.0 - (sbVert.size)); } }

Finally I searched a while by myself, and I think I may answer my own question. Although I couldn't completely resolve my issue, I noticed that the answer is hidden in the other MouseArea events. For example, by handling the onPressed event and adding the mouse.accepted in several key locations, I could let the component take care of the scrolling when the left mouse button is pressed, whereas the right click opens a popup menu.

My conclusion is that there is no ready-to-use way, i.e there is no parameter to activate in the MouseArea itself which may resolve this kind of issue, and the solution is a good balance between activating different parameters in the different functions.

Unfortunately it seems that it's not enough to trigger the scrollbar of the parent.
The solution I found is to set the fixedWidth of the table like this :

int size{ 0 }; for (int i = 0; i < table->columnCount(); ++i) size += table->columnWidth(i); table->setFixedWidth(size);

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.
