How to Capture an Image in a QML
-
I would like to save an image when my QML application is running, just like a camera inside the application,
How can i do that?
-
The source code for the qmlviewer app uses the line
@
QPixmap::grabWidget(canvas).save(snapFileName);
@where canvas is the QDeclarativeView* and snapFileName is the filename to save.
-
where will be the destination of the saved image that i capture?

To the application's working path so I'd add a path to the file. something like QDir::homePath() + "/fileName"
-
can i use this in QML?

You'll need to write some C++ code to handle this. However, with a slot or a Q_INVOKABLE method, you can trigger the functionality from your QML code.

so ill use the .cpp file to use screenshot on my qml
-
yes, put the @mlong inside a slot. Optionally you can pass the path to which you want to save as a parameter.
