コマンドラインからトレイの進行状況を通知する

シェルスクリプトでそれを使用するときの問題は、qdbus org.kde.JobViewServer.requestView要求されたD-Busクライアントがシャットダウンしたときに通知を削除するように設計されているためですdbus-send。qdbusrequestView

リクエストを生成するために使用している場合は、qdbusviewerこのような呼び出しを試してみてください。しかし、接続を開いたままにするためにシェルスクリプトから呼び出すことができる既製の製品を見つけることができるかどうか疑問です。

# Assuming qdbusviewer got /JobViewServer/JobView_15 from the call...

qdbus org.kde.kuiserver /JobViewServer/JobView_15 org.kde.JobViewV2.setInfoMessage 'Frobnicating the foobles...'
qdbus org.kde.kuiserver /JobViewServer/JobView_15 org.kde.JobViewV2.setDescriptionField 1 Cromulence fair
qdbus org.kde.kuiserver /JobViewServer/JobView_15 org.kde.JobViewV2.setPercent 25
qdbus org.kde.kuiserver /JobViewServer/JobView_15 org.kde.JobViewV2.setSpeed 200
qdbus org.kde.kuiserver /JobViewServer/JobView_15 org.kde.JobViewV2.setTotalAmount 100000 bytes
qdbus org.kde.kuiserver /JobViewServer/JobView_15 org.kde.JobViewV2.setProcessedAmount 200 bytes

qdbus org.kde.kuiserver /JobViewServer/JobView_15 org.kde.JobViewV2.terminate 'Received Ctrl+C'

ただし、シェルスクリプトの代わりに少しPythonを使用したい場合は、例を提供できます。する同じタスクに対して、Pythonがシェルスクリプトに非常に良い選択肢であることを保証できます。
