ViewRoot then traverses the view hierarchy to draw them; this phase is called the drawing phase.

environments. Usually when a file hasn’t changed, the build dependencies will ignore it. So, you 
force that file to be compiled by “touch”ing, and thereby updating its time stamp. Just like touch, 
the forceLayout( ) will not invoke any build commands by itself (unless your build environment is too
