[Scilab-users] Callback in checkbox for multiple figures

[Izabela Wójcik-Grząba]

Thank you for your reply. I am not sure why, but your solution doesn't 
work in my example. Maybe it's because the plot and the checkbox are in 
different frames?

Here is my example code (which is a part of my whole programme):

// Definition of figure

f=figure("dockable","off","infobar_visible","off","toolbar_visible","off",..
"toolbar","none","menubar_visible","on","default_axes",..
"off","layout","border","figure_size",[900,750],"background",-2);

// Definition of left frame with the controler of visibility

r_lewa=uicontrol(f,"style","frame","constraints",createConstraints("border",..
"left",[200,0]),"border",createBorder("titled",..
createBorder("line","lightGray",1),("Kontrola rysunku"),..
"center","top"),"backgroundcolor",[1 1 1],"layout_options",..
createLayoutOptions("grid",[2,1]),"layout","grid");

// Definition of right frame with plot

r_prawa=uicontrol(f,"style","frame","constraints",createConstraints("border",..
"center"),"backgroundcolor",[1 1 1]);

newaxes(r_prawa);
drawlater;

// Drawing a plot

x_fix=[1 2 3];y_fix=[2 3 1];z_fix=[1 2 1];
param3d1(x_fix,y_fix,z_fix);
h1=gce();

h1.line_mode="off";
h1.mark_mode="on";
h1.mark_style=9;
h1.mark_foreground=5;
h1.mark_background=5;

// Numbering of points

xstring(x_fix,y_fix,string([1:3]));
num_w=gca().children(1).children;
for i=1:3
     num_w(4-i).data(3)=z_fix(i);
     num_w(i).font_size=3;
end

// Settings of the plot

a=gca();
a.data_bounds=[min(x_fix)-1,min(y_fix)-1,min(z_fix)-1;max(x_fix)+1,max(y_fix)+1,max(z_fix)+1];
a.box="back_half";
a.isoview="on";
a.hidden_axis_color=12;
a.rotation_angles=[-110,245];
title("Siatka ciegnowa w rownowadze","fontsize",4);

// Creating a frame inside the left frame for the controller of 
visibility

przel=uicontrol(r_lewa,"style","frame","constraints",..
createConstraints("gridbag",[1 1 1 1],[0,0],"both","upper"),"border",..
createBorder("titled",createBorder("line","lightGray",1),..
("Widocznosc"),"center","top"),"backgroundcolor",[1 1 1],..
"layout_options",createLayoutOptions("grid",[1,1]),"layout","grid");

// Definition of checkbox which turns on/off the visibility of point 
numbers

box_num_w=uicontrol(przel,"style","checkbox","backgroundcolor",..
[1 1 1],"value",1,"string","Numery wezlow","callback","cbfun");

// Callback function definition

function cbfun()
     h=gcbo();
     ax=h.parent.children(1).children(1);
     ax.children(1).visible=h.value;
endfunction
