get - Retrieve a property value from a graphics entity or an User Interface object.

Calling Sequence

h=get(prop)

val=get(h,prop)

val=h.prop

val=get(n,prop)

Parameters

• h : handle, the handle of the entity to retrieve a property. h can be a vector of handles, in which case get returns the property's value for all objects identified by h(i).
• n : integer, the handle of the User Interface object to retrieve a property.
• prop : character string name of the property.
• val : scilab object value of the property.

Description

This routine can be used to retrieve the value of a specified property graphics entity or a GUI object. If the handle is not specified, the current object is taken as the default handle. It is also used to return a list of all children, parent, or type for the input handle if this one is specified. Otherwise, the current axes object is taken as the default input.

Property name are character strings.

See graphics_entities for details about properties' names and values for graphics entities.

See uicontrol for details about properties' names and values for User Interface objects.

For graphics entities handle it is possible to use a dot notation like h.background instead of get.

Examples

  // for graphics entities
    xbasc()
    get("old_style") // check the state of the graphics' style
    set("figure_style","new") //create a figure
    get("figure_style") // check the style of the graphics' figure

    // simple graphics objects  
    subplot(121);
    x=[-.2:0.1:2*%pi]';
    plot2d(x-2,x.^2);
    subplot(122);
    xrect(.2,.7,.5,.2);     
    xrect(.3,.8,.3,.2);
    xfarc(.25,.55,.1,.15,0,64*360);
    xfarc(.55,.55,.1,.15,0,64*360);
    xstring(0.2,.9,"Example <<A CAR>>");
 
    h=get("hdl") //get the object newly created
    h.font_size=3;
 
    f=get("current_figure") //get the current figure 
    f.figure_size
    f.figure_size=[700 500];
    f.children
    f.children(2).type
    f.children(2).children
    f.children(2).children.children.thickness=4; 
 
    a=get("current_axes") //get the current axes
    a.children.type
    a.children.foreground //get the foreground color of a set of graphics objects
    a.children.foreground=9;

  // for  User Interface objects
   h=uicontrol('string', 'Button'); // Opens a window with a  button.
   p=get(h,'position'); // get the geometric qspect of the button
   disp('Button width: ' + string(p(3))); // print the width of the button
   close(); // close figure
