Text Formatting Flags

DT_BOTTOM Justifies the text to the bottom of the rectangle. This value is used only with the DT_SINGLELINE value.

DT_CALCRECT Determines the width and height of the rectangle. If there are multiple lines of text, DrawText uses the width of the box.

DT_CENTER Centers text horizontally in the rectangle.

DT_EDITCONTROL Duplicates the text-displaying characteristics of a multiline edit control. Specifically, the average character width is calculated in the same manner as for an edit control, and the function does not display a partially visible last line.

DT_END_ELLIPSIS For displayed text, if the end of a string does not fit in the rectangle, it is truncated and ellipses are added. If a word that is not at the end of the string goes beyond the limits of the rectangle, it is truncated without ellipses.

The string is not modified unless the DT_MODIFYSTRING flag is specified.

Compare with DT_PATH_ELLIPSIS and DT_WORD_ELLIPSIS.

DT_EXPANDTABS Expands tab characters. The default number of characters per tab is eight. The DT_WORD_ELLIPSIS, DT_PATH_ELLIPSIS, and DT_END_ELLIPSIS values cannot be used with the DT_EXPANDTABS value.
DT_EXTERNALLEADING Includes the font external leading in line height. Normally, external leading is not included in the height of a line of text.

DT_HIDEPREFIX Windows 2000/XP: Ignores the ampersand (&) prefix character in the text. The letter that follows will not be underlined, but other mnemonic-prefix characters are still processed. For example:

input string: "A&bc&&d"
normal: "Abc&d"
DT_HIDEPREFIX: "Abc&d"

Compare with DT_NOPREFIX and DT_PREFIXONLY.

DT_INTERNAL Uses the system font to calculate text metrics.

DT_LEFT Aligns text to the left.

DT_MODIFYSTRING Modifies the specified string to match the displayed text. This value has no effect unless DT_END_ELLIPSIS or DT_PATH_ELLIPSIS is specified.

DT_NOCLIP Draws without clipping. DrawText is somewhat faster when DT_NOCLIP is used.

DT_NOFULLWIDTHCHARBREAK Windows 98/Me, Windows 2000/XP: Prevents a line break at a DBCS (double-wide character string), so that the line breaking rule is equivalent to SBCS strings. For example, this can be used in Korean windows, for more readability of icon labels. This value has no effect unless DT_WORDBREAK is specified.

DT_NOPREFIX Turns off processing of prefix characters. Normally, DrawText interprets the mnemonic-prefix character & as a directive to underscore the character that follows, and the mnemonic-prefix characters && as a directive to print a single &. By specifying DT_NOPREFIX, this processing is turned off. For example,

input string: "A&bc&&d"
normal: "Abc&d"
DT_NOPREFIX: "A&bc&&d"

Compare with DT_HIDEPREFIX and DT_PREFIXONLY.

DT_PATH_ELLIPSIS For displayed text, replaces characters in the middle of the string with ellipses so that the result fits in the specified rectangle. If the string contains backslash (\) characters, DT_PATH_ELLIPSIS preserves as much as possible of the text after the last backslash.

The string is not modified unless the DT_MODIFYSTRING flag is specified.

Compare with DT_END_ELLIPSIS and DT_WORD_ELLIPSIS.

DT_PREFIXONLY Windows 2000/XP: Draws only an underline at the position of the character following the ampersand (&) prefix character. Does not draw any other characters in the string. For example,

input string: "A&bc&&d"
normal: "Abc&d"
DT_PREFIXONLY: " _ "

Compare with DT_HIDEPREFIX and DT_NOPREFIX.

DT_RIGHT Aligns text to the right.

DT_RTLREADING Layout in right-to-left reading order for bi-directional text when the font selected into the hdc is a Hebrew or Arabic font. The default reading order for all text is left-to-right.

DT_SINGLELINE Displays text on a single line only. Carriage returns and line feeds do not break the line.

DT_TABSTOP Sets tab stops. Bits 15-8 (high-order byte of the low-order word) of the uFormat parameter specify the number of characters for each tab. The default number of characters per tab is eight. The DT_CALCRECT, DT_EXTERNALLEADING, DT_INTERNAL, DT_NOCLIP, and DT_NOPREFIX values cannot be used with the DT_TABSTOP value.

DT_TOP Justifies the text to the top of the rectangle.

DT_VCENTER Centers text vertically. This value is used only with the DT_SINGLELINE value.

DT_WORDBREAK Breaks words. Lines are automatically broken between words if a word would extend past the edge of the rectangle specified by the lpRect parameter. A carriage return-line feed sequence also breaks the line.

If this is not specified, output is on one line.
DT_WORD_ELLIPSIS Truncates any word that does not fit in the rectangle and adds ellipses.

Compare with DT_END_ELLIPSIS and DT_PATH_ELLIPSIS.
