swap_handles
Permute two handles in the graphic Hierarchy.
Syntax
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 rect = xrect( 0.5, 0.5,0.5,0.5) ; // create a circle circle = xarc( 0.5, 0.5, 0.5, 0.5, 0, 64 * 360 ) ; // create an arrow arrow= xpoly([0,1],[0,1]) ; 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 ) ;
