Question to Qt.resolvedUrl () on Windows

[Padlock]

Hello,

I've got a model that provides the path of an image file.

Image {
	id: img
	y: 0
	x: 0
	width: 75
	height: 75
	source:	model.fileIsDir 
		?	"qrc:folder.png"
		:	Qt.resolvedUrl(model.filePath)
	onSourceChanged: {
		console.log ("Image source", model.filePath)
	}
}

The debug window shows:

qml: Image source C:/Users/MyUser/Pictures/IMG_00000001.jpg

and

QML Image: Protocol "c" is unknown

I don't really understand why but I changed the line that contains Qt.resolvedUrl () to

:	Qt.resolvedUrl("file://" + model.filePath)

This means:

Image {
	id: img
	y: 0
	x: 0
	width: 75
	height: 75
	source:	model.fileIsDir 
		?	"qrc:folder.png"
		:	Qt.resolvedUrl("file://" + model.filePath)
	onSourceChanged: {
		console.log ("Image source", model.filePath)
	}
}

Now I receive

QML Image: Cannot open: file://c/Users/MyUser/Pictures/IMG_00000001.jpg

which makes sense. If I try to open that URL in a browser it won't open it either. There's a colon missing. The URL

file://c:/Users/MyUser/Pictures/IMG_00000001.jpg

opens in a browser and displays the picture.

Is Qt.resolvedUrl () not the correct function to call to convert a file system path into a URL?

I think the issue is with the Image {source: ... } property.
I thought I can easily work around this but it doesn't look like it.

This:

QString OneFile::fileURL() const
{
	QString		qsURL	= "file://" + m_FileInfo.filePath ();
	return qsURL;
}

results in the same QML error message:

QML Image: Cannot open: file://c/Users/MyUser/Pictures/IMG_00000001.jpg

Which means that the colon is swalled in QML, somewhere in the Image component.

I also tried this:

QString OneFile::fileURL() const
{
	QString		qsURL	= m_FileInfo.filePath ();
	qsURL.replace (":", "%3A");
	qsURL = "file://" + qsURL;
	return qsURL;
}

This doesn't cause any QML error message. It simply doesn't work. The image is not displayed.

What am I doing wrong?

Got it ;-)

QString OneFile::fileURL() const
{
	return QUrl::fromLocalFile (m_FileInfo.filePath ()).toString ();
}

This topic helped me with the solution:
QQuickWidget no such file issue

Only 4 years late with the response.
Might be a Qt6 thing, but It's file: not file://.

Qt.resolvedUrl("file:" + model.filePath)

Result:

file:///c:/proj/mypro/.....
