programming - Moving controls from Manipulate to a Palette ( or similar GUI object )


Consider the following snippet as a reference.


 DynamicModule[{}, 

  Manipulate[
   Graphics[
     Translate[
       GeometricTransformation[
         { Blue, 
           Polygon[{{0, 0}, {1, 0}, {1, 1}, {0, 1}}]
         }, {{scx, 0}, {0, scy}}
       ], 
       Tuples[{Range[wi], Range[he]}] - 1
     ], 

     ImageSize -> 400 {1, 1}
   ], 
   {{scx, 1, "x scale"}, 0, 1}, 
   {{scy, 1, "y scale"}, 0, 1}, 
   {{wi, 1, "width"}, 1, 5, 1}, 
   {{he, 1, "heigth"}, 1, 5, 1}
  ]
]

Mathematica graphics



A graphical drawing program with a lot of controls (buttons, sliders) would benefit (a lot) by freeing up space and moving controls to a Palette, or a similar construct. I am considering the redesign of a GUI and I am currently investigating the options and technical possibilities. - Looking at the reference code snippet (which is not the GUI in question, but makes asking the question - and answering! - so much easier) I have the following question. Is it possible to move (one of) the sliders to a Palette, or similar construct?



Answer



You can use the "wormhole" construct from "tutorial/AdvancedDynamicFunctionality" like this:


Manipulate[
 Graphics[
  Translate[
   GeometricTransformation[{Blue, 
     Polygon[{{0, 0}, {1, 0}, {1, 1}, {0, 1}}]}, {{scx, 0}, {0, 
      scy}}], Tuples[{Range[wi], Range[he]}] - 1], 
  ImageSize -> 400 {1, 1}],

 OpenerView[{Button["external",
    CreateDialog[DynamicModule[{}, Column[{
        Control[{{scx, 1, "x scale"}, 0, 1}],
        Control[{{scy, 1, "y scale"}, 0, 1}],
        Control[{{wi, 1, "width"}, 1, 5, 1}],
        Control[{{he, 1, "heigth"}, 1, 5, 1}]
        }], InheritScope -> True]
     ]],
   Column[{
     Control[{{scx, 1, "x scale"}, 0, 1}],

     Control[{{scy, 1, "y scale"}, 0, 1}],
     Control[{{wi, 1, "width"}, 1, 5, 1}],
     Control[{{he, 1, "heigth"}, 1, 5, 1}]
     }]}]

 ]

front end - keyboard shortcut to invoke Insert new matrix

I frequently need to type in some matrices, and the menu command Insert > Table/Matrix > New... allows matrices with lines drawn between columns and rows, which is very helpful. I would like to make a keyboard shortcut for it, but cannot find the relevant frontend token command (4209405) for it. Since the FullForm[] and InputForm[] of matrices with lines drawn between rows and columns is the same as those without lines, it's hard to do this via 3rd party system-wide text expanders (e.g. autohotkey or atext on mac). How does one assign a keyboard shortcut for the menu item Insert > Table/Matrix > New... , preferably using only mathematica? Thanks! Answer In the MenuSetup.tr (for linux located in the $InstallationDirectory/SystemFiles/FrontEnd/TextResources/X/ directory), I changed the line MenuItem["&New...", "CreateGridBoxDialog"] to read MenuItem["&New...", "CreateGridBoxDialog", MenuKey["m", Modifiers-...

How to thread a list

I have data in format data = {{a1, a2}, {b1, b2}, {c1, c2}, {d1, d2}} Tableform: I want to thread it to : tdata = {{{a1, b1}, {a2, b2}}, {{a1, c1}, {a2, c2}}, {{a1, d1}, {a2, d2}}} Tableform: And I would like to do better then pseudofunction[n_] := Transpose[{data2[[1]], data2[[n]]}]; SetAttributes[pseudofunction, Listable]; Range[2, 4] // pseudofunction Here is my benchmark data, where data3 is normal sample of real data. data3 = Drop[ExcelWorkBook[[Column1 ;; Column4]], None, 1]; data2 = {a #, b #, c #, d #} & /@ Range[1, 10^5]; data = RandomReal[{0, 1}, {10^6, 4}]; Here is my benchmark code kptnw[list_] := Transpose[{Table[First@#, {Length@# - 1}], Rest@#}, {3, 1, 2}] &@list kptnw2[list_] := Transpose[{ConstantArray[First@#, Length@# - 1], Rest@#}, {3, 1, 2}] &@list OleksandrR[list_] := Flatten[Outer[List, List@First[list], Rest[list], 1], {{2}, {1, 4}}] paradox2[list_] := Partition[Riffle[list[[1]], #], 2] & /@ Drop[list, 1] RM[list_] := FoldList[Transpose[{First@li...

functions - Get leading series expansion term?

Given a function f[x] , I would like to have a function leadingSeries that returns just the leading term in the series around x=0 . For example: leadingSeries[(1/x + 2)/(4 + 1/x^2 + x)] x and leadingSeries[(1/x + 2 + (1 - 1/x^3)/4)/(4 + x)] -(1/(16 x^3)) Is there such a function in Mathematica? Or maybe one can implement it efficiently? EDIT I finally went with the following implementation, based on Carl Woll 's answer: lds[ex_,x_]:=( (ex/.x->(x+O[x]^2))/.SeriesData[U_,Z_,L_List,Mi_,Ma_,De_]:>SeriesData[U,Z,{L[[1]]},Mi,Mi+1,De]//Quiet//Normal) The advantage is, that this one also properly works with functions whose leading term is a constant: lds[Exp[x],x] 1 Answer Update 1 Updated to eliminate SeriesData and to not return additional terms Perhaps you could use: leadingSeries[expr_, x_] := Normal[expr /. x->(x+O[x]^2) /. a_List :> Take[a, 1]] Then for your examples: leadingSeries[(1/x + 2)/(4 + 1/x^2 + x), x] leadingSeries[Exp[x], x] leadingSeries[(1/x + 2 + (1 - 1/x...
