GUI widget_base-children puzzle Help please 1202 0
Started by Deleted User
Hello,
I have this base1 with x dimensions of 606 (according to widget_info/geometry). I have a child section, base2, &160;with the same dimensions (x=606). I then create a progressBar child, within parent base2. (x dimension of this is 257). Everything works fine and right after calling the routine that creates the progressBar the dimensions are: base1 = 606, base2 = 602 (notice it shrank by 4), and progressBar = 257.
PROBLEM IS: If the x-size of base2 (the parent of the progress bar) is sli...

Idle User Management 1334 1
Started by Deleted User
This involves IDL 7.0 and two floating licenses. Currrenty, if a user fails to end their IDL session (and leaves for the day) the associated license is unecessarily tied up and unavailable to other users. Does anyone know of an elegant way to force the user off the license The fact is a non-elegant way would bepreferable to the current situation.

problem with plot title in shade_surf using /t3d keyword 1457 2

I've been working with the shade_surf routine using the /t3d keyword to plot power spectra and have noticed some odd behavior with the title keyword.&160; If you plot a 3D surface using shade_surf, the plot title resides in a plane parallel to the x-z plane.&160; When you project the surface onto a 2D plane using the /t3d keyword, the title and z-axis labels remain in this plane and appear as though you're looking down on the tops of the letters in the title.&160; Here is an example using the...

Colorbar or arrows can't show over contour 1119 0

I have a code that makes a contour and then draws the colorbar. When I run the code on&160; IRIX machine with idl 5.3, the result looks great. But when I run it on the linux server with idl 6.2 or idl 7.0, the colorbar is partially covered by the contour.
In another case, the arrows can't show up at the contour area when run on Linux, but show up when run on IRIX.
Is this a problem caused by the new version of IDL Or is it a problem with Linux Would anybody help me fix the prob...
