Hello,
I think I may be losing my mind, but just in case I'll post the question here:
Has anyone had any weird experiences where using object graphics in IDL causes them to be
logged out of their system?
It's happened to me four times in about the last 30 minutes and I can now reproduce it
relatively regularly with the code I'm testing.
My system is a Red Hat Enterprise 5.0 jobbie with,
IDL> print, !version
{ x86 linux unix linux 7.0 Oct 25 2007 32 64}
I also have the patch installed such that I can get the IDL help running (however the
problem occurs whether or not I start the idlhelp server.)
My *original* direct graphics code looked like:
psave = !P
!P.MULTI = [0,self.n_Bands,1]
FOR i = 0L, self.n_Bands-1L DO BEGIN
PLOT, *(*self.Frequency)[i], *(*self.Response)[i], $
TITLE='Band #'+STRTRIM(i+1,2), $
XTITLE='Frequency', $
YTITLE='Relative response',yrange=[-0.2,1.2]
IF ( N_ELEMENTS(OverPlot) GT 0 ) THEN BEGIN
OPLOT, *(*OverPlot.Frequency)[i], *(*OverPlot.Response)[i], $
COLOR=RED, PSYM=-4
ENDIF
ENDFOR
!P = psave
That's been working fine for a couple weeks now. I started to play around with object
graphics using the examples pretty much directly from the online help and came up with the
following initial code:
mywindow = OBJ_NEW('IDLgrWindow')
myview = OBJ_NEW('IDLgrView', VIEWPLANE_RECT=[-10,-10,20,20])
mymodel = OBJ_NEW('IDLgrModel')
myview->Add, mymodel
myplot = OBJARR(self.n_Bands)
myoplot = OBJARR(self.n_Bands)
FOR i = 0L, self.n_Bands-1L DO BEGIN
myplot[i] = OBJ_NEW('IDLgrPlot', $
*(*self.Frequency)[i], $
*(*self.Response)[i] )
mymodel->Add, myplot[i]
IF ( N_ELEMENTS(OverPlot) GT 0 ) THEN BEGIN
myoplot[i] = OBJ_NEW('IDLgrPlot', $
*(*OverPlot.Frequency)[i], $
*(*OverPlot.Response)[i], $
COLOR=RED)
myoplot[i]->SetProperty, SYMBOL=OBJ_NEW('IDLgrSymbol',COLOR=RED,DATA=4)
mymodel->Add, myoplot[i]
ENDIF
ENDFOR
mywindow->Draw, myview
The fact that the above OG code doesn't actually produce any output in the created object
graphics window is overwhelmingly trivial next to the fact that it also logs me out of my
system (shutting down everything else I had running as well).
Anyone have any ideas, memories, etc about this rather bizarre effect?
cheers,
paulv
