"show" might be thought of as "un-hide", so a window that is not  
visible, or is minimized, will be raised and shown. This often means  
it will be redrawn also.
In contrast, "redraw" marks a window as needing updated, but will not  
affect its z-order, or cause a minimized window to be restored, etc.

No, not really, their functions are quite different.
