One data point about Apple's preference: Safari's Bookmarks menu uses a "globe" icon for pages that lack their own icon, and that monochrome globe icon does switch between light and dark when selected.

@SimonSchroeder I doubt this library can help here. Can you please provide a minimal, compilable example in a bug report? I can take a look on it. Sounds similar to https://bugreports.qt.io/browse/QTBUG-122403 which needs a QIcon instead a QPixmap to make scaling work for your situation.

@TomZ Thank you, I follow the order you mentioned and it works fine. if (doSVG) { painter.setFont(fNum); painter.setPen(pNum); painter.save(); painter.translate(c.toPointF()+ b.toPointF() +tit->pos()); painter.rotate(radToDeg(ra)); painter.drawText(- ti->boundingRect().width()/2, -2, QString::number(n)); painter.restore(); } [image: f90e196d-9f24-4761-b97f-8be48db48754.png]

@Saviz I guess the path of the svg file may not be right. Can you post your qrc file here? do you use qmake or cmake? TabButton { id: root implicitHeight: *** implicitWidth: *** contentItem: Label { anchors.fill: parent Row { spacing: Image { id: buttonImage height: root.height width: root.height source:svg file } Text { text: root.text height: root.height width: root.availableWidth color: "white" horizontalAlignment: Text.AlignLeft verticalAlignment: Text.AlignVCenter } } } }

use splash widget? https://doc.qt.io/qt-6/qsplashscreen.html

@RobotMaker said in Svg Rendering Perspective Transform on QGraphicsView Viewport: Some code will be helpful. And how you update it? try to call this after your change to update it. I use it to toggle svg pics display. update(const QRectF &) ==>update( boundingRect() ); I assume you overrides boundingRect();

As explained here, QSvgWidget has been moved to a new module called QtSvgWidgets. According to the documentation: Header: #include <QSvgWidget> CMake: find_package(Qt6 REQUIRED COMPONENTS SvgWidgets) target_link_libraries(mytarget PRIVATE Qt6::SvgWidgets) qmake: QT += svgwidgets Inherits: QWidget So in Qt6 the solution is following: QT += svgwidgets

@suslucoder said in Svg files does not appear on the screen: There is no error code, i debug it but i cannot find any error also Please simplify your code. Just write a small program that displays 1 PNG image and does nothing else. When that works, replace the PNG image with an SVG image.

Solved it by changing my drawline to: painter.drawLine(QPointF(pX1, pY1), QPointF(pX2, pY2));

Is it possible to to extend QLabel and implement my own paintEvent() that draws the text and draws the svg image? It seems to work, but would problaby take alot of effort to get it right (i.e. to get the image in the right location everytime). void MypLabel::paintEvent(QPaintEvent* event) { QPainter painter(this); const auto pos = QPoint(0, 16); painter.drawText(pos, this->text()); const auto posPixMap = QPoint(30, 0); auto size = QSize(16, 16); auto pixMap = QIcon(":/Resources/smiley.svg").pixmap(size); painter.drawPixmap(posPixMap, pixMap); }

Hi If you open the SVG in say inkscape and change its page size (ViewBox) does it then work as expected in your app ? Im not sure i understand what the goal since QSvgRenderer::setViewBox() did change the rendered size for me with QIcon so are we looking for something else ?

Turns out there is a simple solution: app.setAttribute(Qt.AA_UseHighDpiPixmaps)
