front end - Creating a simple Dock Cell that Fades In when Cursor Hover Over It


I like to create dock cells, that enhance the look of my notebooks. Do you know of a simple way to get the functionality in iBooks shown below in the video. I want the dock cell in Mathematica to "fade" into view when my cursor hover over it and "fade" out when it's not hovering over it.

Edit 1: Thank you Karsten. This is exactly what I was looking for. Below is a gif implementing a version of your code.

Edit: Fading overlay window


In order to get a top dock element with real transparency, one can create a window that overlays the current notebook window and adjusts its position together with it.


With[{nb = EvaluationNotebook[]},
  DynamicModule[{wm, ws},
   CreateWindow[
    PaletteNotebook[
     {DynamicWrapper[TextCell["Click OK to close", Orange], 

       ws = {CurrentValue[nb, WindowSize][[1]] - 15, 100}; 
       wm = AbsoluteCurrentValue[nb, WindowMargins] + {{7, 0}, {70, 50}}, 
       Initialization :> (wm = 
          AbsoluteCurrentValue[nb, WindowMargins] + {{7, 0}, {70, 50}}; 
         ws = {CurrentValue[nb, WindowSize][[1]] - 15, 100})],
      DefaultButton[]}
     , WindowMargins -> Dynamic[Setting@wm], WindowSize -> Dynamic[Setting@ws]
     , TextAlignment -> Center]
    , Background -> Blue
    , WindowOpacity -> 

     Dynamic[1/
       100 (150 - 
         Replace[MousePosition["WindowAbsolute", {0, 1}], None -> {0, 150}][[2]])]
    , WindowFloating -> True, WindowElements -> {}, WindowFrame -> "Frameless"
    , WindowFrameElements -> {}]
   ]];

One can use PaneSelector to create a fading effect.



CurrentValue[EvaluationNotebook[], DockedCells] =
 Cell[BoxData@ToBoxes@PaneSelector[{
      False -> 
       Panel["", ImageSize -> {Full, Automatic}, Appearance -> "Frameless"],
      True -> Panel["Hi", ImageSize -> {Full, Automatic}, Alignment -> Center]
      },
     Dynamic@CurrentValue["MouseOver"]
     , ImageSize -> All
     , ImageMargins -> 0, FrameMargins -> None
     , TransitionEffect -> "Fade", TransitionDirection -> Bottom, TransitionDuration -> 0.75

     ]
  , CellFrameMargins -> {{0, 0}, {0, 0}}]

The size of the DockedCells can be reduces, when the mouse isn't hovering over it:


CurrentValue[EvaluationNotebook[], DockedCells] =
 Cell[BoxData@ToBoxes@PaneSelector[{
      False -> Panel["", ImageSize -> {Full, 0}, Appearance -> "Frameless"],
      True -> Panel["Hi", ImageSize -> {Full, 100}, Alignment -> Center]
      },

     Dynamic@CurrentValue["MouseOver"]
     , ImageSize -> Automatic
     , ImageMargins -> 0, FrameMargins -> None
     , TransitionEffect -> "Fade", TransitionDirection -> Bottom, TransitionDuration -> 0.75
     ]]

list manipulation - Selecting multiple columns from a matrix?

Sample data: data = { {{2013, 1, 1}, 24.13, 167.67, 231.82}, {{2013, 1, 2}, 32.15, 170.92, 225.99}, {{2013, 1, 3}, 35.43, 172.68, 221.67}, {{2013, 1, 4}, 36.73, 173.05, 218.32}, {{2013, 1, 5}, 58.19, 165.96, 197.05}, {{2013, 1, 6}, 69.99, 163.50, 187.52}, {{2013, 1, 7}, 71.37, 154.21, 175.58}, {{2013, 1, 8}, 72.51, 149.66, 163.25}}; I want a DateListPlot with three graphs, so for a matrix formed by columns 1 and 2, one for columns 1 and 3, and 1 for columns 1 and 4. At the moment I'm using this code: data2 = Transpose[{data[[All, 1]], data[[All, 2]]}]; data3 = Transpose[{data[[All, 1]], data[[All, 3]]}]; data4 = Transpose[{data[[All, 1]], data[[All, 4]]}]; DateListPlot[{data2, data3, data4}, Joined -> True, Filling -> {3 -> {1}}] but I have a hunch that this can be done more efficiently. I don't like the Transpose s in particular. Any ideas? edit (for extra credit) What if I need to multiply the second column by 2, which in my solution is simp...

plotting - How to draw lines between specified dots on ListPlot?

I would like to create a plot where I have unconnected dots and some connected. So far, I have figured out how to draw the dots. My code is the following: ListPlot[{{1, 1}, {2, 2}, {3, 3}, {4, 4}, {1, 4}, {2, 5}, {3, 6}, {4, 7}, {1, 7}, {2, 8}, {3, 9}, {4, 10}, {1, 10}, {2, 11}, {3, 12}, {4,13}, {2.5, 7}}, Ticks -> {{1, 2, 3, 4}, None}, AxesStyle -> Thin, TicksStyle -> Directive[Black, Bold, 12], Mesh -> Full] I have thought using ListLinePlot command, but I don't know how to specify to the command to draw only selected lines between the dots. Do have any suggestions/hints on how to do that? Thank you. Answer One possibility would be to use Epilog with Line : ListPlot[ {{1, 1}, {2, 2}, {3, 3}, {4, 4}, {1, 4}, {2, 5}, {3, 6}, {4, 7}, {1, 7}, {2, 8}, {3, 9}, {4, 10}, {1, 10}, {2, 11}, {3, 12}, {4, 13}, {2.5, 7}}, Ticks -> {{1, 2, 3, 4}, None}, AxesStyle -> Thin, TicksStyle -> Directive[Black, Bold, 12], Mesh -> Full, Epilog -> { Line[ ...

dynamic - How can I make a clickable ArrayPlot that returns input?

I would like to create a dynamic ArrayPlot so that the rectangles, when clicked, provide the input. Can I use ArrayPlot for this? Or is there something else I should have to use? Answer ArrayPlot is much more than just a simple array like Grid : it represents a ranged 2D dataset, and its visualization can be finetuned by options like DataReversed and DataRange . These features make it quite complicated to reproduce the same layout and order with Grid . Here I offer AnnotatedArrayPlot which comes in handy when your dataset is more than just a flat 2D array. The dynamic interface allows highlighting individual cells and possibly interacting with them. AnnotatedArrayPlot works the same way as ArrayPlot and accepts the same options plus Enabled , HighlightCoordinates , HighlightStyle and HighlightElementFunction . data = {{Missing["HasSomeMoreData"], GrayLevel[ 1], {RGBColor[0, 1, 1], RGBColor[0, 0, 1], GrayLevel[1]}, RGBColor[0, 1, 0]}, {GrayLevel[0], GrayLevel...
