CDC::SetTextAlign

  • Artigo

Sets the text-alignment flags.

UINT SetTextAlign( 
   UINT nFlags  
);

Parameters

  • nFlags
    Specifies text-alignment flags. The flags specify the relationship between a point and a rectangle that bounds the text. The point can be either the current position or coordinates specified by a text-output function. The rectangle that bounds the text is defined by the adjacent character cells in the text string. The nFlags parameter can be one or more flags from the following three categories. Choose only one flag from each category. The first category affects text alignment in the x-direction:

    • TA_CENTER   Aligns the point with the horizontal center of the bounding rectangle.

    • TA_LEFT   Aligns the point with the left side of the bounding rectangle. This is the default setting.

    • TA_RIGHT   Aligns the point with the right side of the bounding rectangle.

    The second category affects text alignment in the y-direction:

    • TA_BASELINE   Aligns the point with the base line of the chosen font.

    • TA_BOTTOM   Aligns the point with the bottom of the bounding rectangle.

    • TA_TOP   Aligns the point with the top of the bounding rectangle. This is the default setting.

    The third category determines whether the current position is updated when text is written:

    • TA_NOUPDATECP   Does not update the current position after each call to a text-output function. This is the default setting.

    • TA_UPDATECP   Updates the current x-position after each call to a text-output function. The new position is at the right side of the bounding rectangle for the text. When this flag is set, the coordinates specified in calls to the TextOut member function are ignored.

Return Value

The previous text-alignment setting, if successful. The low-order byte contains the horizontal setting and the high-order byte contains the vertical setting; otherwise 0.

Remarks

The TextOut and ExtTextOut member functions use these flags when positioning a string of text on a display or device. The flags specify the relationship between a specific point and a rectangle that bounds the text. The coordinates of this point are passed as parameters to the TextOut member function. The rectangle that bounds the text is formed by the adjacent character cells in the text string.
