Hard to be certain without seeing the whole context, but I'd guess you 
should be adding a Wx::GROW flag to the sizer#add calls. This tells the 
Sizer to expand that item to fill all the space in the non-main sizer 
direction. So, if the sizer's vertical, adding Wx::GROW (or Wx::EXPAND, 
it's a synonym), the listctrl will fill all the horizontal space available.

A few random hints:

@itemSizer = Wx::HBoxSizer.new

And, are you sure you need two sizers?

@itemList = Wx::ListCtrl.new(self,  :style => 
Wx::LC_REPORT|Wx::LC_HRULES|Wx::LC_VRULES)
