In this chapter we learn how to improve our custom warnings by amending them with fixit hints.
So far, we only created warning messages. However, sometimes we also want to add a tip for the user how to fix the code. For that, we can pass an instance of
FixSuggestion
to
emitWarning
. A fix suggestion always consists of a description of what should be fixed, and the location where it should apply. It can also feature a replacement text. By default, the replacement text is only shown in the diagnostic message. By calling
setAutoApplicable(true)
在
FixSuggestion
, the user can however apply the fix automatically via qmllint or the QML language server. It is important to only mark the suggestion as auto-applicable if the resulting code is valid.
