Adding Points to a graphbox

statcon — Wed, 21 Dec 2011 18:37:10 GMT

Hi,

i created an interaktive graph. Now i need to add points (or more general: geometric shapes) to the graphbox.

This should be done on a mousklick using MouseTrap().

I thought of soemthing like that:

// Ad a marker to the graph at the position where the mouse was pressed

::click = function({x,y},

::g << Marker(MarkerState(3), x, y);

::g << Circle(x, y, PixelRadius(10));

);

::w = New Window("Test",

// Some other components (Textboxes...)

::g = Graph Box(

FrameSize( 300, 300 ),

Mousetrap( ::click( x, y ), {} )

)

);

But sadly this does not work. Is there a way to do something like that?

Thanks for any hints!

A couple of points:

- coordinates are typically expressed in a list or matrix format

- the graphical functions operate within a graphics script

The following should work:

::click = function({x,y},

pos = {};

InsertInto(pos,x);

InsertInto(pos,y);

::g[FrameBox(1)] << Add Graphics Script(

Marker(Marker State(3), pos) ;

Circle(pos, PixelRadius(10));

)

);
