TableForm with TableHeadings aligned to Left but the content of table aligned to Right

阅读更多关于 TableForm with TableHeadings aligned to Left but the content of table aligned to Right

问题 TableForm with TableHeadings option is a quick and easy way to display good-looking classical table in Mathematica FrontEnd. The only problem is that it is common to display such a table with headings aligned to the left but the content of the table aligned to the right. Is it possible to force TableForm to behave in this way? Or if not, what is the best way to make an analog of TableForm that behaves in this way? 回答1: You can use Grid and Alignment . Here is one way: a = Map[Mod

Permanent changing FrontEnd behavior to force aborting evaluation of the full sequence of inputs

阅读更多关于 Permanent changing FrontEnd behavior to force aborting evaluation of the full sequence of inputs

问题 This sub-question comes from the question on aborting evaluation of the full sequence of inputs together with previous sub-question. How should we change the file KeyEventTranslations.tr (and/or MenuSetup.tr) to force aborting evaluation of the full sequence of inputs? One possible method to achieve this is described in the previous sub-question associated with another approach: temporary changing of FrontEndEventActions for the current session. I think these questions should be separated as

Is it possible to create MakeBoxesStop wrapper?

阅读更多关于 Is it possible to create MakeBoxesStop wrapper?

问题 It is known that output expressions are passed through MakeBoxes to turn the graphics expressions into the box language which the front end uses to represent graphics (when $Output has default option FormatType->StandardForm ). For example, if we evaluate: HoldComplete[Graphics[Disk[]]] we get a disk wrapped by HoldComplete : This is because HoldComplete does not stop MakeBoxes from converting its contents to typeset expression: In[4]:= MakeBoxes@HoldComplete[Graphics[Disk[]]] Out[4]= RowBox[

Making customized InputForm and ShortInputForm

阅读更多关于 Making customized InputForm and ShortInputForm

问题 I often wish to see the internal representation of Mathematica 's graphical objects not in the FullForm but in much more readable InputForm having the ability to select parts of the code by double-clicking on it and easily copy this code to a new input Cell . But the default InputForm does not allow this since InputForm is displayed by default as a String , not as Mathematica 's code. Is there a way to have InputForm displayed as Mathematica 's code? I also often wish to see a shortened

Why doesn't running ClearAll[“Global`*”] from a custom Palette update local variables colors?

阅读更多关于 Why doesn't running ClearAll[“Global`*”] from a custom Palette update local variables colors?

问题 I created a custom palette, with an ActionMenu that executes ClearAll["Global`*"] . It performs the desired action, but the frontend doesn't instantly update the colors from black to blue (standard), as it happens when ClearAll["Global`*"] is executed directly from a notebook cell (it only updates after something else has been executed). Is there a way to initiate a refresh of the frontend display status? EDIT: Apparently, the same happens when I load a package from a palette (blue doesn’t

Getting the Mathematica front end to obey the FontFamily option

问题 When it comes to Chinese characters, I am unable to get the Front End of Mathematica to use the fonts of my choice. How can I get it to use the fonts I need? Here I provide two screenshots to show the problem, one from Word (top), the other from Mathematica on WinXP, both displaying the same string. Note that Mathematica uses several different fonts (I guess it uses font substitution when the font it tries to use first doesn't contain a glyph---however the font I specified contains all glyphs

How to check whether the FrontEnd considers evaluation still running?

阅读更多关于 How to check whether the FrontEnd considers evaluation still running?

问题 Is there a way to check programmatically whether the FrontEnd considers evaluation still running? Or even better: is there a way to check whether the FrontEnd has some pending inputs to be sent to the kernel? P.S. This question has arisen from previous question. EDIT When evaluating a Cell in the FrontEnd we usually create a queue of inputs for the kernel. I need a function that will return True if the FrontEnd has sent to the kernel the last input of the queue of inputs from the

Mathematica Help Browser from Mathematica 5 in new versions of Mathematica

阅读更多关于 Mathematica Help Browser from Mathematica 5 in new versions of Mathematica

问题 I remember that someone from WRI stated in the official newsgroup that Mathematica 7 still has a working old-fashioned Mathematica Help Browser from Mathematica 5 for compatibility purposes. But I can not find the post where the code for invoking it is given. How to invoke and use this legacy Help Browser in new versions of Mathematica ? 回答1: The old browser will show up if you try to look at documentation for packages that were written in the old format. From the main documentation page,

How to redefine FrontEndEventActions?

阅读更多关于 How to redefine FrontEndEventActions?

Good day, This question comes from the question on aborting evaluation of the full sequence of inputs . I think it is probably possible to achieve the desired behavior by redefining FrontEndEventActions for two events: "EvaluateCells" (or pressing Shift + Enter ) and for pressing Alt + . . It should be something like: SetOptions[$FrontEndSession, FrontEndEventActions -> {"EvaluateCells" :> Last$PreRead, {{"Alt", "."} :> AbortAllNextInputs}}] or SetOptions[$FrontEndSession, FrontEndEventActions -> {{{"ShiftKey", "ReturnKeyDown"} :> Last$PreRead} {{"Alt", "."} :> AbortAllNextInputs}}] Where
