Remove the blue fusion selection from QTreeView

Question

I have a QTreeView with a list of styles that determines the choice. However, when I use the "merge" style, there is an additional blue selection rectangle above the decoration:

I tried using show-decoration-selected: 0; in the stylesheet, and also set setAllColumnsShowFocus(false); but I can't get him to leave.

Is there a way to disable or reinstall the part of the selection that covers the decorator?

For reference, here is the stylesheet:

 QTreeView, QListView, QToolBar, QTableView { show-decoration-selected: 0; background: qlineargradient(x1: 0, y1: 0, x2: 1, y2: 0, stop: 0 #797979, stop: 0.2 #CCCCCC, stop: 1.0 #FFFFFF); alternate-background-color: #333333; background-image: url(:/metal_scratched); outline: 0; /* removes focus rectangle*/ } QTreeView::section, QListView::section, QToolBar::section, QTableView::section { border: 1px solid black; } QTreeView::item:hover:enabled, QListView::item:hover:enabled, QToolBar::item:hover:enabled, QTableView::item:hover:enabled { background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 transparent, stop: 0.4 rgba(150,150,150,0.5), stop: 0.5 rgba(125,125,125,0.5), stop: 1.0 transparent); border-color: #B0B0B0; } QTreeView::item:hover:!enabled, QListView:disabled:hover, QToolBar:disabled:hover, QTableView:disabled:hover { /* don't highlight */ } QTreeView::item:selected, QListView::item:selected, QToolBar::item:selected, QTableView::item:selected { background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 transparent, stop: 0.4 rgba(75,75,75,0.5), stop: 0.5 rgba(50,50,50,0.5), stop: 1.0 transparent); border-color: #5A5A5A; color: white; } 

Answer 1

The blue artifact can be removed by overriding the default selection color in the stylesheet. Leaving everything else the same (important, continuing to define the new highlight color with QTreeView::item:selected ), adding the following property will remove the unwanted behavior.

 QTreeView { // everything else the same selection-background-color: transparent; } 

Answer 2

In a further review, I found that the only way to achieve this is to set the palette of your Qt application.

Thus,

 QApplication app(argc, argv); app.setStyle(QStyleFactory::create("fusion")); QPalette palette; palette.setColor(QPalette::Highlight, QColor(your-color));
