Parameters
Returns
int The number of tracks in the current project
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
# get number of tracks my $nt = RPR_GetNumTracks(); # show in console RPR_ShowConsoleMsg("$nt");
Python
# get number of tracks nt = RPR_GetNumTracks(); # convert to string nt = str(nt); # show in console RPR_ShowConsoleMsg(nt);
