How do I get a real file name off (QtQuick) FileDialog.fileUrl()?
-
I have an app that asks the user to pick an image from the Pictures folder. It returns an URL which the c++ portion of the code is to use. On the c++ side, I have this (the image picked is named "asset.png"):
QUrl url(image_returned_from_fileURL); QString imageName = url.toLocalFile(); qDebug() << imageName;This gets converted to:
"assets-library://asset/asset.PNG?id=732175CD-BE15-44B6-BC1C-7008F03808A1&ext=PNG"
How do I get "asset.png" from this?

Hi,
Something like:
QString localFile = url.toLocalFile(); int start = localFile.lastIndexOf("/") + 1; int length = localFile.indexOf("?id=") - start; QString imageName = localFile.mid(start, length);?

@SGaist I didn't try it (I'll take a look tomorrow) but this would seem to return just the file name, which I agree is what my question technically asked. What I want to have is a usable path to the file that can be used by standard functions like fopen(). The path /asset/asset.png doesn't work. I don't even know where it gets that name from. If I "mail" the image to myself, I get something named IMG_0133.PNG.
Thanks!

Ok, what do you need to do with that file ?

@SGaist I need to give the file name to a third party library that expects a standard const char* file name.
