| 有効/無効設定 | Checks for this warning class are enabled by default.
However, warning instances of this class that are issued as parser
errors (rather than parser warnings)
will be discarded
when using factory configuration settings.
To prevent these instances from being discarded, add the
following WARNING_FILTER rule to the project configuration file.
WARNING_FILTER += allow class="Pointer Conversion Loses Bits" WARNING_FILTER += discard class="Pointer Conversion Loses Bits" |
