SVG file not loading qt 5.6.2 Windows
-
Hi and welcome to devnet,
Did you add "QT += svg" to your .pro file ?
-
Yes. The program works in 5.14 and does not work in 5.6
-
Do you have that issue only with this SVG file or with others as well ?
Check with the examples that comes with the SVG module from 5.6.
-
I have two kinds of svg files. The first file with an additional layer (refresh_.svg) and the second file without an additional layer. I cannot find in the documentation why the file with the additional layer is not loaded.

The description https://doc.qt.io/archives/qt-5.6/svgrendering.html is the same for 5.6 and 5.14. I read the description but found no difference. However 5.6 does not work and 5.14 does ...
-
But there are still a lot of misc changes to this module. Maybe one of them affects your svg file. Don't use such an ancient Qt version. Are you sure the Qt svg plugin is available in the imageformats plugins subdir?
-
Yes, svg is available in the catalog. I am using this old version because the program must work Windows XP
-
Then you have to debug by yourself why it won't load.
-
Is the exact reason unknown? Maybe this is a bug in this case...

@dushabest85 I won't dig into ancient QtSvg sources for you to search for an error. You have to do it by your own.

Maybe some other person knows the answer? Why is the error QPainter :: begin: Paint device returned engine == 0, type: 3?
