Call this member function to write a character string within a rectangular region using the currently selected font.
virtual BOOL ExtTextOut( int x, int y, UINT nOptions, LPCRECT lpRect, LPCTSTR lpszString, UINT nCount, LPINT lpDxWidths ); BOOL ExtTextOut( int x, int y, UINT nOptions, LPCRECT lpRect, const CString& str, LPINT lpDxWidths );
Specifies the logical x-coordinate of the character cell for the first character in the specified string.
Specifies the logical y-coordinate of the top of the character cell for the first character in the specified string.
Specifies the rectangle type. This parameter can be one, both, or neither of the following values:
Points to the specified character string to be drawn. You can also pass a CString object for this parameter.
Specifies the number of characters in the string.
Points to an array of values that indicate the distance between origins of adjacent character cells. For instance, lpDxWidths[i] logical units will separate the origins of character cell i and character cell i + 1. If lpDxWidths is NULL, ExtTextOut uses the default spacing between characters.
A CString object that contains the specified characters to be drawn.
Nonzero if the function is successful; otherwise 0.
The rectangular region can be opaque (filled with the current background color), and it can be a clipping region.
If nOptions is 0 and lpRect is NULL, the function writes text to the device context without using a rectangular region. By default, the current position is not used or updated by the function. If an application needs to update the current position when it calls ExtTextOut, the application can call the CDC member function SetTextAlign with nFlags set to TA_UPDATECP. When this flag is set, Windows ignores x and y on subsequent calls to ExtTextOut and uses the current position instead. When an application uses TA_UPDATECP to update the current position, ExtTextOut sets the current position either to the end of the previous line of text or to the position specified by the last element of the array pointed to by lpDxWidths, whichever is greater.
