Update 24.02.2017 : Der Indikator bietet jetzt die Möglichkeit, Weblinks zu fixieren
Einführung
HINWEIS: Die vorherige Version dieser Antwort befindet sich im Bearbeitungsverlauf, obwohl sie nicht mehr relevant ist.
Der unten dargestellte Indikator war für eine andere Frage gedacht, aber da sich die Gelegenheit bot, habe ich beschlossen, ihn hier zu veröffentlichen. Die Dateianzeige ist eine einfache Anzeige für den Zugriff auf Benutzerdateien und -ordner. Es ermöglicht das Überprüfen kürzlich verwendeter Dateien, das Setzen von Lesezeichen für Dateien und Verzeichnisse. Insbesondere das Menü Orte ist für diese Frage besonders relevant.
Wie Sie auf dem Screenshot sehen können, unterstützt der Indikator auch andere Gebietsschemas als Englisch. Wenn Ihr System also etwas anderes als Englisch verwendet, funktioniert es.
Update : Der Indikator unterstützt jetzt auch das Starten von .desktop-Dateien, die angeheftet wurden. Wenn Sie beispielsweise Firefox.desktop angeheftet haben, wird Firefox gestartet. Somit kann der Indikator als Schnellstarter für Programme verwendet werden. Die Funktion befindet sich zum Zeitpunkt des Schreibens (19. November, 19:53 Uhr GMT, die Verarbeitung sollte ungefähr 24 Stunden dauern) auf dem Weg in PPA, ist jedoch bereits auf Github sowie hier im aktualisierten Quellcode verfügbar.
Den Indikator erhalten
Der Indikator ist sowohl bei meinem persönlichen PPA als auch bei GitHub erhältlich . Führen Sie die folgenden Schritte aus, um es zu erhalten:
sudo add-apt-repository ppa:1047481448-2/sergkolo
sudo apt-get update
sudo apt-get install files-indicator

Konfigurationen
Der Indikator wird über zwei JSON-Dateien konfiguriert, die im Home-Verzeichnis des Benutzers gespeichert sind.
~/.files_indicator.json Steuert die Benutzeroberfläche, die Länge der Menüeinträge und die maximale Anzahl im Menü "Zuletzt verwendete Dateien".
{
"name_length": 30,
"max_items": 10
}
Das ~/.pinned_files.jsonsteuert die Listen der angehefteten Dateien und Ordner. Jedes Element ist eine Liste / ein Array.
{
"dirs": [
"/home/xieerqi/\u56fe\u7247/Wallpapers"
],
"files": [
"/home/xieerqi/work_in_progress/videonauth_code.py",
"/home/xieerqi/work_in_progress/spin_button.py"
]
}
]
