        1_1524812058948_2.png
        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..

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

            @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 ?

                  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.
