Mobile versionDa es kein Systray-Menü für WPF-Anwendungen gibt, habe ich das Windows-Formular NotiIcon und ContextMenuStrip verwendet.
I haben ToolStripProfessionalRenderer mit ProfessionalColorTable vollständig angepasst, um den Dunkelmodus
gemäß den Anforderungen der Kunden zu unterstützen. Jetzt suche ich nach einer Umrundung. Mir wurde „RoundedEdges = true;“
verwendet, aber es hat nicht funktioniert. Ich muss genau wissen, welche Methode überschrieben werden muss, um die Ecke von ContextMenuStrip zu umgehen.

Hier unten ist mein Renderer-Beispielcode.
