On “handles handles” You will often see Scilab’s Scilab s Help Browser refer to a “handle, handle,” but Help does not provide a helpful explanation of the term. Here is a brief account: �� In graphics software the word handle refers to the points placed around a figure or plot that allow you to manipulate the object (see figure) �� A Matlab tutorial gives the following explanation that is also valid for Scilab: “Whenever Whenever Matlab creates a graphics object, it assigns an identifier (called handle) handle) to it. You can use this handle to access the object’s object s properties.” properties. �� You need handles to edit graphical plots beyond the means offered offered by basic plot functions (plot2d() ( plot2d(), , plot3d(), plot3d() etc.) �� We’ll We ll return handles when discussing graphics & plotting (Ch. 7)
Check handles with gcf() gcf() �� The function plot2d() produces the plot below �� The command gcf() gcf() gives the list to the right �� The list is the handle for the defined function (Scilab literature also refers to individual rows in the list by the term “handle handle”) -->x = linspace(0,4*%pi,100); plot2d(x,0.5*cos(x)) -->f = gcf() f = Handle of type "Figure" with properties: ======================================== children: "Axes“ figure_position = [567,485] figure_size = [628,592] axes_size = [610,460] auto_resize = "on“ viewport = [0,0] figure_name = "Graphic window number %d“ figure_id = 0 info_message = "“ color_map= matrix 32x3 pixmap = "off“ pixel_drawing_mode = "copy“ anti_aliasing = "off“ immediate_drawing = "on“ background = -2 visible = "on“ rotation_style = "unary“ event_handler = "“ event_handler_enable = "off“ user_data = [] tag = ""
