Members
- cbSize
Size of this structure, in bytes. The application must fill this member before sending any messages that use the address of this structure as a parameter.
fMask
Flags that indicate which members of this structure are valid or must be filled. It can be a combination of the following values.Value Description RBBIM_BACKGROUND
The hbmBack member is valid or must be filled.
RBBIM_CHILD
The hwndChild member is valid or must be filled.
RBBIM_CHILDSIZE
The cxMinChild and cyMinChild members are valid or must be filled.
RBBIM_COLORS
The clrFore and clrBack members are valid or must be filled.
RBBIM_IDEALSIZE
The cxIdeal member is valid or must be filled.
RBBIM_ID
The wID member is valid or must be filled.
RBBIM_IMAGE
The iImage member is valid or must be filled.
RBBIM_LPARAM
The lParam member is valid or must be filled.
RBBIM_SIZE
The cx member is valid or must be filled.
RBBIM_STYLE
The fStyle member is valid or must be filled.
RBBIM_TEXT
The lpText member is valid or must be filled.
fStyle
Flags that specify the band style. It can be a combination of the following values.Value Description 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_FIXEDBMP
The background bitmap does not move when the band is resized.
RBBS_FIXEDSIZE
The band cannot be sized. With this style, the sizing grip is not displayed on the band.
RBBS_GRIPPERALWAYS
The band will always have sizing grip, even if it is the only band in the rebar.
RBBS_HIDDEN
The band will not be visible.
RBBS_NOVERT
The band is not displayed when the rebar control uses the CCS_VERT style.
RBBS_VARIABLEHEIGHT
The band can be resized by the rebar control. cyIntegral and cyMaxChild affect how the rebar will resize the band.
- clrForeand clrBack
Band foreground and background colors. If hbmBack specifies a background bitmap, these members are ignored.
- lpText
Long pointer to a buffer that contains the display text for the band. If band information is being requested from the control and RBBIM_TEXT is specified in fMask, this member must be initialized to the address of the buffer that will receive the text.
- cch
Size of the buffer at lpText, in bytes. If information is not being requested from the control, this member is ignored.
- iImage
Zero-based index of any image that should be displayed in the band, if any. The image list is set using the RB_SETBARINFO message.
- hwndChild
Handle to the child window contained in the band, if any.
- cxMinChild
Minimum length of the child window, in pixels. The band cannot be sized smaller than this value.
- cyMinChild
Minimum thickness of the child window, in pixels. The band cannot be sized smaller than this value.
- cx
Length of the band, in pixels.
- hbmBack
Handle to a bitmap that is used as the background for this band.
- wID
Unsigned integer that the control uses to identify this band for Custom Draw messages. This value may be used for additional purposes in the future.
- cyChild
Initial height of the band, in pixels. This member is ignored unless the RBBS_VARIABLEHEIGHT style is specified.
- cyMaxChild
Maximum height of the band, in pixels. This member is ignored unless the RBBS_VARIABLEHEIGHT style is specified.
- cyIntegral
Specifies the step value by which the band can grow or shrink, in pixels. If the band is resized, it will be resized in steps specified by this value. This member is ignored unless the RBBS_VARIABLEHEIGHT style is specified.
- cxIdeal
Specifies the ideal width of the band, in pixels. If the band is maximized to the ideal width (see RB_MAXIMIZEBAND), the rebar control will attempt to make the band this width.
- lParam
Specifies a 32-bit application-defined value.
Remarks
The cxMinChild, cyMinChild, and cx members provide information on dimensions relative to the orientation of the control. That is, for a horizontal rebar control, cxMinChild and cx are horizontal measurements and cyMinChild is a vertical measurement. However, if the control uses the CCS_VERT style, cxMinChild and cx are vertical measurements and cyMinChild is a horizontal measurement.
