relative path to external resource
-
Hi there :D
I am playing around with Qt for WebAssembly and was wondering, how to use assets from a relative path from the compiled warm if deployed on a server?
Assuming I use some images in my application, I would normally embed them in my qrc resource file,
but for WA the compiled binary is already really large, so I thought I could load the images directly from the hosting server, is this possible?Image { //source: "../../assets/BG.jpg" // local, using embedded resource from arc file //source: "file:///assets/BG.jpg" // local, absolute path -> works for desktop build //source: "http://my.server.com/BG.jpg" // online absolute path -> works for WA build, although I have to pay respect to the protocol (http or https), also difficult because of CORS if deployed on another server source: "file:/BG.jpg" // online relative path how to? }trying to load an image from a relative path throws me an error:
QML Image: Cannot open: file:///BG.jpgDo I have to map my relative path to an absolute like in this post: https://forum.qt.io/topic/76590/relative-path-to-absolute-path or is there another way to achieve this?
best regards

SyntaX@SyntaX You would need to preload the files at compile time.
