Examples
C++
void HorizZoomSelItems() { HWND hTrackView = GetTrackWnd(); if (!hTrackView) return; RECT r; GetClientRect(hTrackView, &r); // Find the coordinates of the first and last selected item double x1 = 1.0e300, x2 = -1.0e300; for (int i = 1; i <= GetNumTracks(); i++) { MediaTrack* tr = CSurf_TrackFromID(i, false); if (GetTrackVis(tr) & 2) for (int j = 0; j < GetTrackNumMediaItems(tr); j++) { MediaItem* mi = GetTrackMediaItem(tr, j); if (*(bool*)GetSetMediaItemInfo(mi, "B_UISEL", NULL)) { double d = *(double*)GetSetMediaItemInfo(mi, "D_POSITION", NULL); if (d < x1) x1 = d; d += *(double*)GetSetMediaItemInfo(mi, "D_LENGTH", NULL); if (d > x2) x2 = d; } } } if (x1 >= 1.0e300) return; adjustZoom(0.94 * r.right / (x2 - x1), 1, false, -1); SetHorizPos(hTrackView, x1, 0.03); }
Perl
# Example - Show number of items on selected track.pl use strict; use warnings; use constant CURR_PROJ => 0; # Get pointer to first track in selection my $Track_ID = RPR_GetSelectedTrack(CURR_PROJ, 0); # Get numer of items on track my $Item_Count = RPR_GetTrackNumMediaItems($Track_ID); # Display summary message if (! $Item_Count) { RPR_ShowConsoleMsg("Selected track has no items.\n"); } elsif ($Item_Count == 1) { RPR_ShowConsoleMsg("Selected track has 1 item.\n"); } else { RPR_ShowConsoleMsg("Selected track has $Item_Count items.\n"); }
