Stylesheet on custom tableview
Solved

Hi,
I made a table view with an item delegate.
I also redifine paint event like this:void MdCommandTableView::paintEvent(QPaintEvent* event) { if(!m_pixBackgroundBottom.isNull()) { QPainter painter(viewport()); QRect rect(viewport()->rect()); painter.fillRect(rect, Qt::white); if(height() < width()) { int iHeight = height() / 1.5; int iWidth = ((double)m_pixBackgroundBottom.size().width() / (double)m_pixBackgroundBottom.size().height()) * iHeight; painter.drawPixmap(0, height() - iHeight, iWidth,iHeight, m_pixBackgroundBottom); iWidth = ((double)m_pixBackgroundTop.size().width() / (double)m_pixBackgroundTop.size().height()) * iHeight; painter.drawPixmap(width() - iWidth, 0, iWidth,iHeight, m_pixBackgroundTop); } else { int iWidth = width(); int iHeight = ((double)m_pixBackgroundBottom.size().height() / (double)m_pixBackgroundBottom.size().width()) * (double)iWidth; painter.drawPixmap(0, height() - iHeight, iWidth,iHeight, m_pixBackgroundBottom); iHeight = ((double)m_pixBackgroundTop.size().height() / (double)m_pixBackgroundTop.size().width()) * (double)iWidth; painter.drawPixmap(width() - iWidth, 0, iWidth,iHeight, m_pixBackgroundTop); } painter.end(); } QTableView::paintEvent(event); }I would like to customize the scrollbar with a stylesheets:
QScrollBar:horizontal { border: 1px solid #999999; background:white; width:10px; border-radius: 5px; margin: 0px 0px 0px 0px; } QScrollBar::handle:horizontal { background: qlineargradient(x1:0, y1:0, x2:1, y2:0, stop: 0 rgb(150, 150, 150), stop: 0.5 rgb(130, 130, 130), stop:1 rgb(114, 114, 114)); min-height: 0px; border-radius: 5px; } QScrollBar::add-line:horizontal { background: qlineargradient(x1:0, y1:0, x2:1, y2:0, stop: 0 rgb(150, 150, 150), stop: 0.5 rgb(130, 130, 130), stop:1 rgb(114, 114, 114)); height: 0px; subcontrol-position: bottom; subcontrol-origin: margin; } QScrollBar::sub-line:horizontal { background: qlineargradient(x1:0, y1:0, x2:1, y2:0, stop: 0 rgb(150, 150, 150), stop: 0.5 rgb(130, 130, 130), stop:1 rgb(114, 114, 114)); height: 0 px; subcontrol-position: top; subcontrol-origin: margin; }But with stylesheet the scrollbars are never displayed...
Ho can I draw the scrollbars ?thanks,
Sorry for my english -
Hi,
Can you also show how you setup your QTableView subclass ?

I implement my table view like this:

Do you have that code available somewhere ?
The model setup is missing and its difficult to reproduce what is happening to you.
Also, which version of Qt are you using ?
On which OS ? -
Glad you found out and thanks for sharing !
I was about to write that on further look there where zeros in your stylesheet but you were faster :)
