/** Add any child window derived from VWindow to the VReBar control. This
function will determine the size of the child window and create a band
in the rebar that matches the size of the child window. The band will be
identified by the ID that was passed to the Create() method of the child
window. The nIndex paramater specifies the zero based index where the
band will be inserted. If you set this parameter to -1, the control will
add the new band at the last location. The pszText parameter can be used
to add a label to the rebar band, which will be displayed in front of
the child window. The nIndex paramater specifies the zero based index
where the band will be inserted. If you set this parameter to -1, the
control will add the new band at the last location. The nStyle
parameter can be a combination of the following styles:
RBBS_BREAK - The band is on a new line.
RBBS_CHILDEDGE - The band has an edge at the top and bottom of the
child window.
RBBS_FIXEDSIZE - The band can't be sized. With this style, the sizing
grip is not displayed on the band.
RBBS_GRIPPERALWAYS - Version 4.71. The band will always have a sizing
grip, even if it is the only band in the rebar.
RBBS_HIDDEN - The band will not be visible.
RBBS_CHEVRON - Version 5.00. The band will have a chevron.
RBBS_NOGRIPPER - Version 4.71. The band will never have a sizing grip,
even if there is more than one band in the rebar.
RBBS_VARIABLEHEIGHT - Version 4.71. The band can be resized by the
rebar control.
If you need more control over the method used to insert the band into
the rebar control, see the InsertBand() method.*/
