[ROOT] full screen window/zooming y-axis

Hi,
  Could someone post or send to me directly code to get the full 
available screen size -- the dimensions needed to create a TCanvas 
filling the whole screen?
  Is it possible for macros to grab input from the console without 
blocking graphics updates? Is it possible for macros to access the 
functionality of Getline.C?
  From the documentation and examples, it sounds like it should be 
easy to zoom in on the y-axis of a TH1F or TGraph by clicking the left 
mouse button and dragging along the y-axis.  I do this and a box is drawn 
around the y region as it for a successful zoom in on the x-axis -- however, 
after I release the mouse button, the box just disappears and nothing 
else happens. (I'm using ROOT  version 2.23/12 1 February 2000 under RH 
Linux 6.1.) Do I have to do something special to zoom in on the y-axis?
  Sorry for the unrelated sequence of questions. Thank you for your 
patience.

David
