UpdateItemInProject()
void UpdateItemInProject(MediaItem* item)
Use this function to redraw an object after it has been updated if the redraw is not triggered automatically.
Some API functions that may change the item's appearance won't automatically trigger a redraw of the item. This triggers a redraw of the item by REAPER.
Parameters
MediaItem* item
Returns
void
Examples
C++
Perl

I # assign [the two scripts to convenient keys whilst playing # the section containing the item]" # use strict; use warnings; use constant CURR_PROJ => 0; use constant FIRST_SELECTED => 0; $MediaItem = RPR_GetSelectedMediaItem(CURR_PROJ, FIRST_SELECTED); $D_VOL = RPR_GetMediaItemInfo_Value($MediaItem, "D_VOL"); $Item_Vol = (20 * log($D_VOL)) / log(10); $Item_Vol = sprintf "%.0f", $Item_Vol; $Item_Vol++; $D_VOL = 10 ** ($Item_Vol / 20); RPR_SetMediaItemInfo_Value($MediaItem, "D_VOL", $D_VOL); RPR_UpdateItemInProject($MediaItem);
