How do I dynamically load images during runtime.
Example: Album Art, Contact Pictures, etc.Currently I'm using array kind of implementation but it really requires the images to be embedded inside the executable. But I found it difficult when any new addition/deletion to the music/contact database are done.
My C++ code reads the filename and pass the file name to the QML and it also places the file inside the "pics" folder. But still I couldn't able to see the images unless & until I load the images using qml.qrc->resource editor
I get the below error if I don't add the file physically.
QML Image: Cannot open: qrc:/qml/pics/Bluetooth.png -
Hi,
Your question is not quite clear. Do you mean add new pictures at run time that were not available when you built your application ?

@Vyuvaraj What is the name format which C++ sends to Qml? What is it like? You may use imageprovider to send images directly to Qml

I wanted to make it dynamic, so that I reduce the number of hardcoded file names and file into the project. I'm expecting something like "looking to a specific folder where the exe is placed and using the required picture(s) during runtime".

How would you determine the name of the files to use in your application ?

Hi, you can add file:// in front of the path of your files in order to load images outside qrc.
i.e. file:///home/media/pic1.jpg or so. -

@SGaist I use a template like the below
<AlbumDetails Name = "Album 1" Art = "Album1.jpg">
<Song Name = "Song 1" Artist = "Artist 1"/>
<Song Name = "Song 2" Artist = "Artist 2"/>
<Song Name = "Song 3" Artist = "Artist 1, Artist 2"/>
</AlbumDetails>I will create a list of Songs under each Album details which also contains Album Art jpg file name.

As @rrlopez already wrote, use the file:// scheme and you can access the files.
