[Scilab-Dev] xcos blocks showing dynamic parameters

[Clément David]

Hello,

In Xcos, we use images or text rendering to display the blocks icons.
These settings can be modified using a CSS-like key-value properties on
xcosPalAddBlock. Take a look at the style argument.

Basically, to display the second exprs text on the block, use
style="displayedLabel=%2$s". An exemple is provided on
SCI/contrib/xcos_toolbox_skeleton.

> - In the "set" case of the interface function: assign new values to these variables and store them in the arg1.graphics.exprs list.
> - In the "plot" case of the interface function: unpack the same variables from arg1.graphics.exprs and call standard_draw.

> I do see blocks like CONST_m displaying their parameter and changing them dynamically after assigning new parameter values. What I do not see is how it is done: I do not see, after the dialog is dismissed in scicos_getvalues, where the parameter gets to be displayed on the xcos diagram.
