Rebar controls support a variety of control styles in addition to standard window styles.
Version 4.71. The rebar control will automatically change the layout of the bands when the size or position of the control changes. An RBN_AUTOSIZE notification will be sent when this occurs.
Version 4.71. The rebar control displays narrow lines to separate adjacent bands.
Version 4.71. The rebar band will toggle its maximized or minimized state when the user double-clicks the band. Without this style, the maximized or minimized state is toggled when the user single-clicks on the band.
Version 4.70. The rebar control always displays bands in the same order. You can move bands to different rows, but the band order is static.
Version 4.71. The rebar control displays bands at the minimum required height, when possible. Without this style, the rebar control displays all bands at the same height, using the height of the tallest visible band to determine the height of other bands.
Version 4.71. The size grip will be displayed vertically instead of horizontally in a vertical rebar control. This style is ignored for rebar controls that do not have the CCS_VERT style.
