__init__()
abstract requestImageResponse(id, requestedSize)
Parameters:

  • id – str

  • requestedSize – QSize

Return type:

QQuickImageResponse

Implement this method to return the job that will provide the texture with id.

The id is the requested image source, with the “image:” scheme and provider identifier removed. For example, if the image source was “image://myprovider/icons/home”, the given id would be “icons/home”.

The requestedSize corresponds to the Image::sourceSize requested by an Image item. If requestedSize is a valid size, the image returned should be of that size.

Note

this method may be called by multiple threads, so ensure the implementation of this method is reentrant.
