An application sends a ZGM_HIGHLIGHTCURSORROW message to enable or disable the highlighting of the row of the cursor.
ZGM_HIGHLIGHTCURSORROW
wParam = (WPARAM) (BOOL) fEnable; //enable flag
lParam = 0; //not used; must be zero
This message does not return a value.
If cursor row highlighting is disabled, cursor row highlighting in fixed columns (ZGM_HIGHLIGHTCURSORROWINFIXEDCOLUMNS) is disabled.
Cursor row highlighting is enabled by default.
