Rappture Element for Matrixes

A GUI element that creates a 3X3 Matrix of numbers. With a put and get for each cell. Rather than parsing strings.

    I’m thinking of adding a “layout” option to groups. Layout hints might be something like “vertcal”, “horizontal”, etc. If we added support for “3×3”, we might be able to make a group of numbers look like a 3×3 matrix.

    Another way to solve this might be by making a “table” object, which could be set up with any number of rows/columns.

    I’d like to solve this problem one of those two ways, rather than by making a specialized “matrix” object.

    I’d like to create the specialized 3×3 version (noting that this doesn’t eliminate the need for a more generalized layout).

    The 3×3 version will look like a group of 9 numbers. Right now, I’m assuming hardcoded element names like e11 e12 e13 e21 e22 e23 e31 e32 e33. This means that the application must explicitly get the values of the matrix one-by-one. Furthermore, you can enable or disable elements (e.g. you may want to user to be able to edit the diagonal, but none of the other elements).

    Why a specialized 3×3 widget?

    It can be made simpler to use. It can be made to look better.

    I think the general case is a table widget. I think it’s clearer how to handle a table in the Rappture 2.0 framework. But in the 1.x time frame, I don’t know how to represent the input and output in a form that doesn’t require a lot of parsing.

      Is this rappture element realated to ‘my’ Periodic Table? Somewhat?
