GETWINDOWS

GETWINDOWS

The GETWINDOWS function retrieves either a specific graphic window or all graphics windows.

Example


p = PLOT(/TEST)
c = CONTOUR(/TEST)
pwin = GetWindows('Plot')
HELP, pwin
 
win = GetWindows(NAMES=winNames)
HELP, win
PRINT, winNames

When this example is run, IDL prints:

PWIN            OBJREF    = Array[1]
WIN             OBJREF    = Array[2]
Plot Contour
