PARAFORMAT2 Structure

The PARAFORMAT2 structure contains information about paragraph formatting attributes in a rich edit control. PARAFORMAT2 is a Microsoft® Rich Edit 2.0 extension of the PARAFORMAT structure. Rich Edit 2.0 allows you to use either structure with the EM_GETPARAFORMAT and EM_SETPARAFORMAT messages.

Members

cbSize

Structure size, in bytes. Before passing this structure to a rich edit control, set cbSize to the size of the PARAFORMAT or PARAFORMAT2 structure. If cbSize equals the size of a PARAFORMAT structure, the control uses only the PARAFORMAT members.

dwMask

The members of the PARAFORMAT2 structure that contain valid information. The dwMask member can be a combination of the values from two sets of bit flags. One set indicates the structure members that are valid; another set indicates the valid attributes in the wEffects member.

Set the following values to indicate the valid structure members.

Value	Meaning
PFM_ALIGNMENT	The wAlignment member is valid.
PFM_BORDER	The wBorderSpace, wBorderWidth, and wBorders members are valid.
PFM_LINESPACING	The dyLineSpacing and bLineSpacingRule members are valid.
PFM_NUMBERING	The wNumbering member is valid.
PFM_NUMBERINGSTART	The wNumberingStart member is valid.
PFM_NUMBERINGSTYLE	The wNumberingStyle member is valid.
PFM_NUMBERINGTAB	The wNumberingTab member is valid.
PFM_OFFSET	The dxOffset member is valid.
PFM_OFFSETINDENT	The dxStartIndent member is valid. If you are setting the indentation, dxStartIndent specifies the amount to indent relative to the current indentation.
PFM_RIGHTINDENT	The dxRightIndent member is valid.
PFM_SHADING	The wShadingWeight and wShadingStyle members are valid.
PFM_SPACEAFTER	The dySpaceAfter member is valid.
PFM_SPACEBEFORE	The dySpaceBefore member is valid.
PFM_STARTINDENT	The dxStartIndent member is valid and specifies the indentation from the left margin. If both PFM_STARTINDENT and PFM_OFFSETINDENT are specified, PFM_STARTINDENT takes precedence.
PFM_STYLE	The sStyle member is valid.
PFM_TABSTOPS	The cTabCount and rgxTabs members are valid.

 

Set the following values to indicate the valid attributes of the wEffects member.

Value	Meaning
PFM_DONOTHYPHEN	The PFE_DONOTHYPHEN value is valid.
PFM_KEEP	The PFE_KEEP value is valid.
PFM_KEEPNEXT	The PFE_KEEPNEXT value is valid.
PFM_NOLINENUMBER	The PFE_NOLINENUMBER value is valid.
PFM_NOWIDOWCONTROL	The PFE_NOWIDOWCONTROL value is valid.
PFM_PAGEBREAKBEFORE	The PFE_PAGEBREAKBEFORE value is valid.
PFM_RTLPARA	The PFE_RTLPARA value is valid.
PFM_SIDEBYSIDE	The PFE_SIDEBYSIDE value is valid.
PFM_TABLE	The PFE_TABLE value is valid.

wNumbering

Options used for bulleted or numbered paragraphs. To use this member, set the PFM_NUMBERING flag in the dwMask member. This member can be one of the following values.

Value	Meaning
zero	No paragraph numbering or bullets.
PFN_BULLET	Insert a bullet at the beginning of each selected paragraph.

Rich Edit versions earlier than version 3.0 do not display paragraph numbers. However, for compatibility with Microsoft Text Object Model (TOM) interfaces, wNumbering can specify one of the following values.

Value	Meaning
2	Uses Arabic numbers (1, 2, 3, ...).
3	Uses lowercase letters (a, b, c, ...).
4	Uses uppercase letters (A, B, C, ...).
5	Uses lowercase Roman numerals (i, ii, iii, ...).
6	Uses uppercase Roman numerals (I, II, III, ...).
7	Uses a sequence of characters beginning with the Unicode character specified by the wNumberingStart member.

 

The rich edit control stores the value but does not use it to display the text.

wEffects

This member is also known as wReserved for Rich Edit 1.0 because it was reserved.

Rich Edit 1.0:  Reserved; the value must be zero.

Rich Edit 2.0: A set of bit flags that specify paragraph effects. These flags are included only for compatibility with Text Object Model (TOM) interfaces; the rich edit control stores the value but does not use it to display the text.

This member can be a combination of the following values.

PFE_DONOTHYPHEN

Disables automatic hyphenation.

PFE_KEEP

No page break within the paragraph.

PFE_KEEPNEXT

No page break between this paragraph and the next.

PFE_NOLINENUMBER

Disables line numbering (in Rich Edit 3.0 only).

PFE_NOWIDOWCONTROL

Disables widow and orphan control for the selected paragraph.

PFE_PAGEBREAKBEFORE

Inserts a page break before the selected paragraph.

PFE_RTLPARA

Displays text using right-to-left reading order (in Rich Edit 2.1 and later).

PFE_SIDEBYSIDE

Displays paragraphs side by side.

PFE_TABLE

The paragraph is a table row.

dxStartIndent

Indentation of the paragraph's first line, in twips. The indentation of subsequent lines depends on the dxOffset member. To use the dxStartIndent member, set the PFM_STARTINDENT or PFM_OFFSETINDENT flag in the dwMask member. If you are setting the indentation, use the PFM_STARTINDENT flag to specify an absolute indentation from the left margin; or use the PFM_OFFSETINDENT flag to specify an indentation relative to the paragraph's current indentation. Use either flag to retrieve the current indentation.

dxRightIndent

Indentation of the right side of the paragraph, relative to the right margin, in twips. To use this member, set the PFM_RIGHTINDENT flag in the dwMask member.

dxOffset

Indentation of the second and subsequent lines, relative to the indentation of the first line, in twips. The first line is indented if this member is negative or outdented if this member is positive. To use this member, set the PFM_OFFSET flag in the dwMask member.

wAlignment

Paragraph alignment. To use this member, set the PFM_ALIGNMENT flag in the dwMask member. This member can be one of the following values.

PFA_LEFT

Paragraphs are aligned with the left margin.

PFA_RIGHT

Paragraphs are aligned with the right margin.

PFA_CENTER

Paragraphs are centered.

PFA_JUSTIFY

Rich Edit 2.0: Paragraphs are justified. This value is included for compatibility with TOM interfaces; rich edit controls earlier than Rich Edit 3.0 display the text aligned with the left margin.

PFA_FULL_INTERWORD

Paragraphs are justified by expanding the blanks alone.

cTabCount

Number of tab stops defined in the rgxTabs array.

rgxTabs

Array of absolute tab stop positions. Each element in the array specifies information about a tab stop. The 24 low-order bits specify the absolute offset, in twips. To use this member, set the PFM_TABSTOPS flag in the dwMask member.

Rich Edit 2.0: For compatibility with TOM interfaces, you can use the eight high-order bits to store additional information about each tab stop.

Bits 28-31 can specify one of the following values to indicate the type of tab leader. These bits do not affect the rich edit control display.

Value	Meaning
0	No leader
1	Dotted leader
2	Dashed leader
3	Underlined leader
4	Thick line leader
5	Double line leader

Bits 24-27 can specify one of the following values to indicate the tab alignment. These bits do not affect the rich edit control display for versions earlier than Rich Edit 3.0.

0

Ordinary tab

1

Center tab

2

Right-aligned tab

3

Decimal tab

4

Word bar tab (vertical bar)

dySpaceBefore

Size of the spacing above the paragraph, in twips. To use this member, set the PFM_SPACEBEFORE flag in the dwMask member. The value must be greater than or equal to zero.

dySpaceAfter

Specifies the size of the spacing below the paragraph, in twips. To use this member, set the PFM_SPACEAFTER flag in the dwMask member. The value must be greater than or equal to zero.

dyLineSpacing

Spacing between lines. For a description of how this value is interpreted, see the bLineSpacingRule member. To use this member, set the PFM_LINESPACING flag in the dwMask member.

sStyle

Text style. To use this member, set the PFM_STYLE flag in the dwMask member. This member is included only for compatibility with TOM interfaces and Microsoft Word; the rich edit control stores the value but does not use it to display the text.

bLineSpacingRule

Type of line spacing. To use this member, set the PFM_SPACEAFTER flag in the dwMask member. This member can be one of the following values.

0

Single spacing. The dyLineSpacing member is ignored.

1

One-and-a-half spacing. The dyLineSpacing member is ignored.

2

Double spacing. The dyLineSpacing member is ignored.

3

The dyLineSpacing member specifies the spacingfrom one line to the next, in twips. However, if dyLineSpacing specifies a value that is less than single spacing, the control displays single-spaced text.

4

The dyLineSpacing member specifies the spacing from one line to the next, in twips. The control uses the exact spacing specified, even if dyLineSpacing specifies a value that is less than single spacing.

5

The value of dyLineSpacing / 20 is the spacing, in lines, from one line to the next. Thus, setting dyLineSpacing to 20 produces single-spaced text, 40 is double spaced, 60 is triple spaced, and so on.

bOutlineLevel

Reserved; must be zero.

wShadingWeight

Percentage foreground color used in shading. The wShadingStyle member specifies the foreground and background shading colors. A value of 5 indicates a shading color consisting of 5 percent foreground color and 95 percent background color. To use these members, set the PFM_SHADING flag in the dwMask member. This member is included only for compatibility with Word; the rich edit control stores the value but does not use it to display the text.

wShadingStyle

Style and colors used for background shading. Bits 0 to 3 contain the shading style, bits 4 to 7 contain the foreground color index, and bits 8 to 11 contain the background color index. To use this member, set the PFM_SHADING flag in the dwMask member. This member is included only for compatibility with Word; the rich edit control stores the value but does not use it to display the text.

The foreground and background color indexes can be one of the following values.

Value	Color	Value	Color
0	Black	8	Dark blue
1	Blue	9	Dark cyan
2	Cyan	10	Dark green
3	Green	11	Dark magenta

To use this member, set the PFM_NUMBERINGSTART flag in the dwMask member.

wNumberingStyle

Numbering style used with numbered paragraphs. Use this member in conjunction with the wNumbering member. This member is included only for compatibility with TOM interfaces; the rich edit control stores the value but rich edit versions earlier than 3.0 do not use it to display the text or bullets. To use this member, set the PFM_NUMBERINGSTYLE flag in the dwMask member. This member can be one of the following values.
