Stop autoscrolling of QScrollArea

Actually, when we insert from the top, slider position is already 0 & resetting it to 0 won't work

@Viki_Dev

Where is the file?

[Viki_Dev]

this is loaded on clicking - pageup

this is loaded on clicking - pagedown

middle items are not loaded, the are loaded as scrolling, but when scrolling from bottom to top, scrollarea moves automatically up. it should not do so..

@Viki_Dev

Can you show what you do in "page up" and "page down" ?

[Viki_Dev]

@Ratzz
There is a timer which calls a updateMainArea method which refreshes these 600 items in every 10ms, on page up & page down, I am just changing start & end index, due to which items are getting loaded from top/bottom as required & also increased as index changed

void Widget::on_upButton_clicked()
{
clearScrollView();
m_iStartIndex = 0;
m_iEndIndex = m_iNumberOfVisibleRecord;
}

void Widget::on_downButton_clicked()
{
clearScrollView();
m_iStartIndex = MAX_RECORD_COUNT-m_iNumberOfVisibleRecord;
m_iEndIndex = MAX_RECORD_COUNT;
updateMainArea();
ui->scrollArea->verticalScrollBar()->setValue(ui->scrollArea->verticalScrollBar()->maximum());
}

Is there a way I can pass you this project.. ? I am new to this website...

Hi,

Out of curiosity, why not use a QTableView for that ?

[Viki_Dev]

@SGaist lots of implementation have been done already, it not good to change now

Hi,
doesn't the Upload File option work when you edit a post (see image)?

That's odd...
As a workaround, you could also use some temporary storage and pass the link.
For example, https://expirebox.com/. Files will only be available for download for 2 days though. There are plenty of other possibilities out there it seems.
