set

Arguments

h

graphic handle of the entity which to set the named property. h can be a vector of handles, in which case set modifies the property for all entities contained in h.

prop

character string, name of the property to set.

val

value to give to the property.

Description

This routine can be used to modify the value of a specified property from a graphics entity or a GUI object. In this case it is equivalent to use the dot operator on an handle. For exemple, set(h,"background",5) is equivalent to h.background = 5.

Property names are character strings. The type of the set values depends on the handle type and property.

To get the list of all existing properties see graphics_entities or uicontrol for User Interface objects.

set function can be also called with only a property and a value as argument. In this case, the property must be one of the following:

current_entity or hdl

set('current_entity',h) or set('hdl',h) sets a new entity as current. In this case, the value must be a graphic handle.

current_figure

set('current_figure',fig) sets a new graphic figure as current. It is equivalent to scf. In this case, the value must be a Figure handle.

current_axes

set('current_axes',axes) sets a new axes entity as current. It is equivalent to sca. In this case, the value must be an Axes handle.

set can also be called with a graphic handle and property as arguments. The handle must be either a handle on the default figure or the default axes entities. The property must be "default_values". In this case, the default entity is reset to the value it had at Scilab startup. set("default_values",h) is equivalent to sda or sdf.

Examples

clf()
set("auto_clear","off") ;
// Exemple of a Plot 2D
x=[-.2:0.1:2*%pi]';
plot2d(x-.3,[sin(x-1) cos(2*x)],[1 2] );
a=get("current_axes");
p1=a.children.children(1);
p2=a.children.children(2);
// set the named properties to the specified values on the objects
set(p2,"foreground",13);
set(p2,"polyline_style",2);
set(a,'tight_limits',"on");
set(a,"box","off");
set(a,"sub_tics",[ 7 0 ]);
set(a,"y_location","middle")
set(p2,'thickness',2);
set(p1,'mark_mode',"on");
set(p1,'mark_style',3);
plot2d(x-2,x.^2/20);
p3= a.children(1).children;
set([a p1 p2 p3],"foreground",5)
