class TGLayoutHints: public TObject, public TRefCnt

A number of different layout classes (TGLayoutManager,
TGVerticalLayout, TGHorizontalLayout, TGLayoutHints, etc.).

Concerning the TGMatrixLayout class:

It arranges frames in a matrix-like way.
This manager provides :
- a column number (0 means unlimited)
- a row number (0 means unlimited)
- horizontal & vertical separators

Notes : If both column and row are fixed values, any remaining
frames outside the count won't be managed.
Unlimited rows means the frame can expand downward
(the default behaviour in most UI).
Both unlimited rows and columns is undefined (read: will
crash the algorithm ;-).
With fixed dimensions, frames are always arranged in rows.
That is: 1st frame is at position (0,0), next one is at
row(0), column(1) and so on...
When specifying one dimension as unlimited (i.e. row=0 or
column=0) the frames are arranged according to the direction
of the fixed dimension. This layout manager does not make
use of TGLayoutHints.
