QGraphicsSvg

[Ra_J]

hi,
I'm loading a complete SVG file to graphicsView.
Below is the code which is working fine.
QGraphicsScene *scene = new QGraphicsScene();
QGraphicsSvgItem *item = new QGraphicsSvgItem("C://svg//deckmain.svg");
scene->addItem(item);
scene->setBackgroundBrush(Qt::gray);
ui->graphicsView->setScene(scene);
item->setZValue(0);
ui->graphicsView->fitInView(scene->sceneRect(), Qt::KeepAspectRatio);
ui->graphicsView->show();

===
I want to access layers , Path objects created in SVG. So i can change color, select the object with mouse. hide ON/OFF of layers and objects in the file.

Please someone can guide me.

Thanks,

this may be the example you want to have a peek at

Thanks. I need to access layers and elements by using SVG file

@Ra_J Qt does not have the ability to do that. I recommend you look for another library that is used to manipulate the svg since Qt only serves to render.

@Ra_J You cannot manipulate individual SVG elements in QGraphicsSvgItem. However, you can call setElementId() and only display a sub-element in the Item. Create multiple QGraphicsSvgItems and set a different element ID for each.

See the example code at https://doc.qt.io/qt-5/qgraphicssvgitem.html

You can then:

• Call QGraphicsItem::setVisible() to show/hide an item.
• Apply QGraphicsColorizeEffect to change the colour of an item.

To make this work, you probably need to re-organize your SVG file a bit.

@JKSH Thanks, I will try this. I m new to QT so finding it difficult. You are right need to organize SVG file as per requirement.
