.Dd October 28, 2015 .Dt UPDATE_PANELS 3 .Os .Sh NAME .Nm update_panels .Nd update terminal display .Sh LIBRARY .Lb libpanel .Sh SYNOPSIS n panel.h
.Ft void .Fn update_panels "void"
.Sh DESCRIPTION The .Fn update_panels function performs the internal processing required by the panel library to determine what changes need to be made to synchronise the curses internal screen buffer and the terminal but does not modify the terminal display.
p This function will internally perform the required calls to .Xr touchoverlap 3 and .Xr wnoutrefresh 3 in the correct order. You should never directly call curses functions like .Xr wnoutrefresh 3 on panel windows yourself. Remember, that .Dv stdscr is below all panels and any changes to it also require calling .Fn update_panels .
p Finally, call the curses function .Xr doupdate 3 to update the terminal display. .Sh SEE ALSO .Xr doupdate 3 , .Xr panel 3
