Dear All,
I am involved in developing SymPy based application.
Python being a very powerful tool by itself, I am leveraging on its
simplicity for creating user interfaces for SymPy. The context of
current layout is to design some thing like a calculator with buttons.
Please feel free to give me your views in designing the keypad layout.
If you know any other layout like this kindly let me know.
Objectives::
To create an user interface for people in all levels
By default, it should be like a calculator
Two modes possible:
**Calculator mode: (the input box can be edited only with buttons,
just like a calc.)
**CAG Mode: (more like a command prompt, along with buttons to insert
predefined texts and provides hints)
With that in mind, I have categorized the keypad as a nested class.
For now, the class (schematically) looks like this
=================================
Class:: Function:
Members::
* Name (ex: 'integrate')
* Function (ex: 'integrate')
* Syntax (ex: '(,)' )
* Variable Hint (ex: ['function', 'variable'])
* Example (ex: 'var('x'); integrate(sin(x),x)' )
* arguments []
* Children Functions[] (if child present, clicking the function will
open another window of functions)
* Button properties (size, position etc.)
Member Methods::
IsValid( ) :: Check the arguments recursively if they are valid
(returns true or false)
evalfunc() :: Evaluate the function (throws exception if not valid)
AddChild(Function e):: add the function to the children functions
making this instance a KeyPad.
=================================
The layout will have many categorized Pads (like algebra, calculus
etc.) with relevant functions in them. The default pad will resemble
an ordinary calculator.
Thanks in advance for your views.
Regards,
Shyam
