An Introduction to Programming with Mathematica using .net vs 2010 todeploy qr barcode with web,windows application upc barcode Making buttons the easy way The simplest way to create buttons is to select an expression in your Mathematica notebook, choose Create Button from the Input menu, and then activate your button. Let us walk through these steps to create a button that pastes an expression into your notebook. Suppose you were writing a paper in which you are discussing sequences and you need to use an expression such as the following repeatedly in your notebook: a1 , a2 , , an .

To create a button that would allow you to paste this expression into your notebook by simply clicking that button, we first write down the expression we will work with below in a regular input cell.. a1 , a2 , , an Now select the entire expression and choose Create Button menu. a1 , a2 , , an Paste from the Input Finally, to activate qr codes for .NET the button so that you can click it to have an action occur, select the cell in which the button occurs and then choose Cell Properties Cell Active from the Cell menu..

a1 , a2 , , an Clicking the above b Quick Response Code for .NET utton will paste the following at the insertion point: a1 , a2 , , an . If you wished, you could create a free-standing palette from this button by choosing Generate Palette from Selection from the File menu.

Although the above procedure for creating buttons is quite straightforward, it is only convenient for fairly simple buttons. For more complicated buttons you will find that you need a good understanding of the structure of buttons and the various options that control their actions and display. We turn to those topics in the next few sections.

. The structure of buttons Buttons are created .net vs 2010 qr barcode with the ButtonBox function in Mathematica. ButtonBox takes one argument and by default, that argument is pasted at the current selection point.

In the examples that follow, we will use DisplayForm to display the button as an interactive element. If you were to unformat your button (Show Expression from the Format menu), you would see essentially all that precedes the DisplayForm below..

10 Front end programming In[1]:=. ButtonBox "some text", Active True DisplayForm Out[1]//DisplayForm= some text Note that we have ad QR Code for .NET ded the option Active True. This makes the resulting button uneditable, one that is clickable.

You will need to add this option to all your buttons to activate them. Clicking this button causes the following to be pasted at the current selection point..

some text Let us create a button that can serve as a template for a definite integral. In[2]:=. ButtonBox["Integrate[fun,{x,xmin,xmax}]", Active->True] //DisplayForm Out[2]//DisplayForm= Integrate fun, x, xmin, xmax Clicking the button causes the following to be pasted in. Integrate fun, x, xmin, xmax We can use placehold ers in our template button so that the user can move from one can be placeholder to the next by pressing the Tab key. The placeholder character entered either from the Complete Characters palette (look under Letter-like Forms and -sp(pressing the then Keyboard Forms), or directly from the keyboard by typing Escape key, then the characters s and then p, and finally the closing Escape key)..

In[3]:=. ButtonBox["Integrate[ ,{ , , }]", Active->True] //DisplayForm Out[3]//DisplayForm= Integrate Clicking on this but QR Code 2d barcode for .NET ton causes the following expression to be pasted. You can move from one placeholder to another by pressing the Tab key.

. Integrate , , ,. An Introduction to Programming with Mathematica ButtonStyle Although having butt qrcode for .NET ons that paste their contents at the current selection point is useful, there is much more that buttons can do. For example, they can wrap the contents of the ButtonBox around a selected expression and then evaluate that expression.

To change the default behavior of buttons from simply pasting their contents to other actions, we have to use the ButtonStyle option. ButtonStyle is used to control both the style and the actions associated with your buttons. In the following example, ButtonStyle is set to CopyEvaluateCell.

. In[4]:=. ButtonBox "Integrate .net framework QR Code JIS X 0510 ,x ", Active ButtonStyle "CopyEvaluateCell". True, DisplayForm The character is ent QR for .NET ered either from palettes or directly from the keyboard by typing -spl- . Evaluating the above input produces the cell below.

Selecting the input x5 and then clicking the button causes the template to be cell containing Cos x2 wrapped around the selected expression and then it is evaluated..
