BackgroundRole color change not taking effect in QTableView with stylesheet

cdemuru

Good morning,

I have created a TableView that uses a model that sets the Background Role to a yellow color when a warning is associated with a certain element contained in the model. It works fine except when I apply a stylesheet.

QTableView {
  qproperty-showGrid: false;
  qproperty-alternatingRowColors: false;
  color: rgb(216, 217, 218);
  border: 1px solid transparent;
  border-radius: 5px;
  background-color: rgb(45, 50, 54);
  selection-color: rgb(172, 0, 122);
  selection-background-color: transparent;
  margin: 10px;
  outline: none;
}

QTableView::item {
  border: 1px solid rgb(64, 66, 62);
  border-top-color: transparent;
  border-right-color: transparent;
  border-left-color: transparent;
  padding-left: 20px;
}

The graphic effect you see is that the cell has a different background than the one set by changing the BackgroundRole.

Perhaps this is not the right way to dynamically style a table's cells. Can you suggest me the correct approach to solve my problem?

As described in the documentation: "Note: If Qt Style Sheets are used on the same widget as functions that set the appearance of widgets, such as QWidget::setFont() or QTreeWidgetItem::setBackground(), style sheets will take precedence if the settings conflict."

Use a custom QStyledItemDelegate.
