参数
| $tagNMHDR | Contains information about a notification message |
| dwDrawStage | The current drawing stage. This is one of the following values: Global Values: $CDDS_POSTERASE - After the erasing cycle is complete. $CDDS_POSTPAINT - After the painting cycle is complete. $CDDS_PREERASE - Before the erasing cycle begins. $CDDS_PREPAINT - Before the painting cycle begins.
