CMFCColorBar::CreateControl
Creates a color bar control window, attaches it to the CMFCColorBar object, and resizes the control window to contain the specified palette of colors.
virtual BOOL CreateControl(
CWnd* pParentWnd,
const CRect& rect,
UINT nID,
int nColumns=-1,
CPalette* pPalette=NULL
);
[in] pParentWnd
Pointer to the parent window. Cannot be NULL.[in] rect
A bounding rectangle that specifies where to draw the color bar control.[in] nID
The control ID.[in] nColumns
The ideal number of columns in the color bar control. This method modifies that number to fit the specified palette of colors. The default is -1, which means this parameter is not specified.[in] pPalette
Pointer to a palette of colors, or NULL. If this parameter is NULL, this method calculates the size of the color bar control as if 20 colors were specified. The default is NULL.
TRUE if this method succeeds; otherwise FALSE.
This method uses the rect, nColumns, and pPalette parameters to calculate the appropriate number or rows and columns in the color bar control, and then calls the CMFCColorBar::Create method.
