There is a code in the documentation: ref @ SetPropertyValue[{"myTableModel", "columnIdentifiers"}, {"One", "Two", "Three"}] (where ref is GUIKit`GUIObject like this: ref = GUIRun[ Widget["Panel", { Widget["Scroll... 11 Feb 2010 08:17

Checking that MathKernel is still running
Hello, I have a program that uses separate MathKernel for a very long computation. Main kernel calls LinkWrite[link, EvaluatePacket[...]] then calls LinkRead[link] and waits until the computation will be completed. But sometimes this additional kernel may shut down due to some reason ("No more memory availa... 10 Feb 2010 04:29

Execute on Exit?
Hi. Is it possible to run a command upon system close? The 'close' menu binding is customisable but doesn't seem to accept a sequence of tokens, e.g. Item["E&xit", KernelExecute[CustomFunction[]]; "FrontEndQuit"] The top-right close button isn't affected by the menu binding though. Thanks in advance. ... 12 Feb 2010 05:28

LogPlot is blank when Exported as pdf
Hi, I'm basically having the same problem as a previous poster from 8th August 2009, who's post wasn't answered: "I am having trouble to export a LogLogPlot to which I have added a legend with ShowLegend. I'm doing something like: plot = LogLogPlot[function[t], {t,tmin,tmax}, PlotOptions] plotWithLeg ... 11 Feb 2010 08:17

A question about Graphics3D
Dear Sir, I am a Mathematica 7 user. I have two questions about Graphics3D[Point[my data]]; *First question:* * * How can I color some points in my data in the above "Graphics3D" by different colors? *Second question:* How can I represent some points also in my data in the above "Graphics3D" by shap... 11 Feb 2010 08:17

Upright \[Micro] in AxesLabel
Hello, how can I get an upright \[Micro] within AxesLabel? E.g. Plot[x^2,{x,0,9},AxesLabel->{"Time [d]","Height [\[Micro]m]"},LabelStyle->{FontSize->20,FontSlant->Plain}] should demonstrate the problem. Just \[Micro] remains slanted. However, turning on bold typeface (this is not what I need) Plot[x^2,{x,0,9},... 13 Feb 2010 06:02

I'd like to obtain greater numerical accuracy on a contour integral I'm working on over a closed contour that I'd like to represent parametrically as {x(t),y(t)} in the form of InterpolationFunctions. However I noticed when I attempt to obtain the derivatives of the Interp... 9 Feb 2010 02:55

Difference between Animator and Trigger?
I'm trying to decide whether to use an Animator or a Trigger to drive an animation, but it looks like they're pretty much identical, just with different default settings. Is there a difference? If not, why are there two commands? Thanks, Brad ... 12 Feb 2010 05:28
