Operations that involve communication with digital cameras can
|
|
take some time. For example, downloading an image over a slow serial
|
|
line can take several minutes. In order to be able to keep the frontend
|
|
responsive, to give the user the possibility to cancel operations, and in
|
|
order to be able to
|
|
report detailed error messages, #GPContext has been introduced.
