Split window

Ulrich Utiger

Posted 10 years ago

Is there a mean to split horizontally the Mathematica window? This would be very useful in comparing code within a notebook that contains a lot of code of several pages. Please introduce this in your next version of Mathematica.

Maybe this will help? Hyperlink["https://mathematica.stackexchange.com/questions/9280/open-\ two-copies-of-the-same-notebook", \ CreatePalette[ Button["Duplicate Active Notebook", NotebookPut[ NotebookGet[ InputNotebook[]] /. {Rule[DockedCells, _] :> Sequence[], Rule[WindowMargins, _] :> Rule[WindowMargins, {{0, Automatic}, {0, Automatic}}], Cell[x___] :> Cell[x, Evaluatable -> False]}, Background -> GrayLevel[0.95], Editable -> False, "ClosingSaveDialog" -> False, DockedCells -> With[{sourcenb = InputNotebook[]}, Cell[BoxData[ ToBoxes[Button["Update", SelectionMove[InputNotebook[], All, Notebook]; NotebookWrite[InputNotebook[], NotebookGet[sourcenb] /. Cell[x___] :> Cell[x, Evaluatable -> False]]]]], "DockedCell", CellContext -> Cell]], WindowTitle -> "Duplicate of " <> AbsoluteOptions[InputNotebook[], WindowTitle][[1, 2]]]; SetSelectedNotebook[InputNotebook[]]], WindowTitle -> "Duplicate"]; Regards,...Jos

No it has not been implemented. It's really crazy. You can do the most exotic things with Mathematica but you cannot split the same notebook into two parts. This is like driving a Mercedes that has no rear-view mirrors. Stephen Wolfram, read this: WE NEED TO SPLIT NOTEBOOKS INTO TWO WINDOWS BECAUSE THEY ARE USUALLY VERY LONG. SO PLEASE INSERT THIS SIMPLE CODE INTO MATHEMATICA AFTER ASKING FOR IT FOR SEVERAL YEARS! GOT IT?

Four years have passed... Has this feature now been implemented in Mathematica 12?

One alternative is to open a second instance of Mathematica by right-clicking on the icon in the task-bar and then clicking on the icon again. Then open the same notebook in both instances and but them side-by-side. But the problem here is that a modification in one instance will not be delegated to the other instance. So modifications should only be made in one instance otherwise parts will be lost. So it's also a "low-tech" solution.
