swap_handles

Permute two handles in the graphic Hierarchy.

Calling Sequence

swap_handle( handle1, handle2 )

Arguments

handle1

first handle of the permutation.

handle2

second handle of the permutation.

Description

The swap_handles function allows to permute two handles in the graphic hierarchy. The first handle will take the second handle position and vice versa.

The handles must have the same parent type or the same type to avoid incompatibilities.

This routine may be used on children of the same parent to change their indices.

Examples

//-----------------//
//  First example  //
//-----------------//

// create a rectangle
xrect( 0.5, 0.5,0.5,0.5) ;
rect = gce() ;

// create a circle
xarc( 0.5, 0.5, 0.5, 0.5, 0, 64 * 360 ) ;
circle = gce() ;

// create an arrow
xpoly([0,1],[0,1]) ;
arrow = gce() ;
arrow.polyline_style = 4 ;
arrow.arrow_size_factor = 4 ;

// get the list of children
axes = gca()  ;
axes.children

// change the order
swap_handles( rect, arrow ) ;
swap_handles( arrow, circle ) ;

// get the new order
axes.children

//-----------------//
//  Second example //
//-----------------//

// create two windows
plot2d ;
axes1 = gca() ;

scf() ;
fec ;
axes2 = gca() ;

// swap their axes
// note that the color map does not change.
swap_handles( axes1, axes2 ) ;
