<div>Hello,<br/>
<br/>
You can use "resume" to return values in caller environment.<br/>
In case of callbacks from gui interaction, caller is always "console" scope.<br/>
<br/>
In your callback do something like "data = resume(a);"<br/>
That's create or overwrite "data" with the contents of "a"<br/>
<br/>
Example :<br/>
<br/>
<tt>xdel(winsid());</tt><br/>
<tt>clear createGUI callbackFromGui;</tt><br/>
<br/>
<tt>function createGUI()</tt><br/>
<tt> f = figure(...</tt><br/>
<tt> "dockable", "off", ...</tt><br/>
<tt> "axes_size", [300 100], ...</tt><br/>
<tt> "infobar_visible", "off", ...</tt><br/>
<tt> "toolbar", "none", ...</tt><br/>
<tt> "menubar_visible", "on", ...</tt><br/>
<tt> "menubar", "none", ...</tt><br/>
<tt> "default_axes", "off", ...</tt><br/>
<tt> "background", color(255, 255, 255));</tt><br/>
<br/>
<tt> uicontrol(f, ...</tt><br/>
<tt> "style", "pushbutton", ...</tt><br/>
<tt> "string", "Send variable in console context", ...</tt><br/>
<tt> "position", [(300 - 200)/2 (100 - 25)/2 200 25], ...</tt><br/>
<tt> "callback", "callbackFromGui");</tt><br/>
<tt>endfunction</tt><br/>
<br/>
<tt>function callbackFromGui()</tt><br/>
<tt> a = rand(10, 10);</tt><br/>
<tt> data = resume(a);</tt><br/>
<tt>endfunction</tt><br/>
<br/>
<tt>createGUI();</tt><br/>
<br/>
After clicking on the button, you should have a "data" variable in the console.</div>

<div style="font-family: Verdana;font-size: 12.0px;">
<div>I wrote a SCE-Script where you can read datafiles into a matrix and specify the import parameter AND the name of matrix where the data is stored in a GUI. Because variables in sce are visible to Scilab I could work with the matrix which name was specified in the GUI in Scilab's console.</div>
<div> </div>
<div>Now I wrote a toolbox where I call this script from a menu item (addmenu) with exec("myscrip.sce",-1). The toolbox works fine so far and run the script properly but the matrix variable is not visible in Scilab. Obviously Scilab handles variables in sce in a toolbox differently?</div>
<div> </div>
<div>The script itself works fine and provide the variable if I run the sce directly outside the toolbox. The sce has no dependencies to external SCIs.</div>
<div> </div>
<div>Who can I make this variable visible for Scilab from a toolbox?</div>
<div> </div>
<div>Thanks, Hani</div>
<div> </div>
<div>PS: The toolbox should run on Scilab 5.5.x and 6.0.x.</div>

<p>Hello,</p>
<p>Please give us a small and reproductive example, under the form of two scripts (the one creating the menu and the one executed by selecting the menu item).</p>
<p>S.</p>
