Hi guys I began to reflect on the problem of drawing a table of values following the ideas given by Vincent and Gustavo. I wrote something which is still archaic (I warned you, in terms of programming I have the age of an infant)
let me explain the procedure: the app window is W x H pixels. The ploting area is of W-XG x H-YG, begining at XG,YG. Creates 2 evas_images (W-XG x H-YG): The first supports the points (x_i, y_i), the axes oX, oY, and the graduations the second supports the gride we need to transform the set of values due to the orientation of axes and the origin of coordinates. In this transformation we only use 75% of the ploting area. Usage of the programme : ./prg datafile [pt] [motif] if pt null, then dont plot lines between points motif = c, p, l, s (cross, plus, losange, stars) I need lotof help: I create with the aide of embed some ewl_butons (open data, save, help, zoom). How can I attache a callback which reads a datafile (pointer to datafile). I can not find how to handle from a EVAS, other window (ewl or evas). thank you to anyone who can give me an example. Last question Can'I publish the programme here for discussion? ------------------------------------------------------------------------------ _______________________________________________ enlightenment-devel mailing list enlightenment-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/enlightenment-devel
