int DrawText( const char FAR* lpString, int nCount, LPRECT lpRect, UINT nFormat );
lpString
Points to the string to be drawn. If nCount is -1, the string must be null-terminated.
nCount
Specifies the number of bytes in the string. If nCount is -1, then lpString is assumed to be a long pointer to a null-terminated string and DrawText computes the character count automatically.
lpRect
Points to a RECT structure or CRect object that contains the rectangle (in logical coordinates) in which the text is to be formatted.
nFormat
Specifies the method of formatting the text. It can be any combination of the following values (combine using the bitwise-OR operator):
| Value | Meaning |
| DT_BOTTOM | Specifies bottom-justified text. This value must be combined with DT_SINGLELINE. |
| DT_CALCRECT | Determines the width and height of the rectangle. If there are multiple lines of text, DrawText will use the width of the rectangle pointed to by lpRect and extend the base of the rectangle to bound the last line of text. If there is only one line of text, DrawText will modify the right side of the rectangle so that it bounds the last character in the line. In either case, DrawText returns the height of the formatted text but does not draw the text. |
| DT_CENTER | Centers text horizontally. |
| DT_EXPANDTABS | Expands tab characters. The default number of characters per tab is eight. |
| DT_EXTERNALLEADING | Includes the font's external leading in the line height. Normally, external leading is not included in the height of a line of text. |
| DT_LEFT | Aligns text flush-left. |
| DT_NOCLIP | Draws without clipping. DrawText is somewhat faster when DT_NOCLIP is used. |
| DT_NOPREFIX | Turns off processing of prefix characters. Normally, DrawText interprets the ampersand (&) mnemonic-prefix character as a directive to underscore the character that follows, and the two-ampersand (&&) mnemonic-prefix characters as a directive to print a single ampersand. By specifiying DT_NOPREFIX this processing is turned off. |
| DT_RIGHT | Aligns text flush-right. |
| DT_SINGLELINE | Specifies single line only. Carriage returns and linefeeds do not break the line. |
| DT_TABSTOP | Sets tab stops. The high-order byte of nFormat is the number of characters for each tab. The default number of characters per tab is eight. |
| DT_TOP | Specifies top-justified text (single line only). |
| DT_VCENTER | Specifies vertically centered text (single line only). |
| DT_WORDBREAK | Specifies word-breaking. Lines are automatically broken between words if a word would extend past the edge of the rectangle specified by lpRect. A carriage return–linefeed sequence will also break the line. |
Note that the values DT_CALCRECT, DT_EXTERNALLEADING, DT_INTERNAL, DT_NOCLIP, and DT_NOPREFIX values cannot be used with the DT_TABSTOP value.
Draws formatted text in the rectangle specified by lpRect. It formats text by expanding tabs into appropriate spaces, aligning text to the left, right, or center of the given rectangle, and breaking text into lines that fit within the given rectangle. The type of formatting is specified by nFormat.
This member function uses the device context's selected font, text color, and background color to draw the text. Unless the DT_NOCLIP format is used, DrawText clips the text so that the text does not appear outside the given rectangle. All formatting is assumed to have multiple lines unless the DT_SINGLELINE format is given.
If the selected font is too large for the specified rectangle, the DrawText member function does not attempt to substitute a smaller font.
The height of the text.
