The TextFormat class represents character formatting information. Use the TextFormat class to create specific text formatting for text fields. You can apply text formatting to both static and dynamic text fields. The properties of the TextFormat class apply to device and embedded fonts. However, for embedded fonts, bold and italic text actually require specific fonts. If you want to display bold or italic text with an embedded font, you need to embed the bold and italic variations of that font.
You must use the constructor new TextFormat()
to create a
TextFormat object before setting its properties. When you apply a
TextFormat object to a text field using the
TextField.defaultTextFormat
property or the
TextField.setTextFormat()
method, only its defined properties
are applied. Use the TextField.defaultTextFormat
property to
apply formatting BEFORE you add text to the TextField
, and the
setTextFormat()
method to add formatting AFTER you add text to
the TextField
. The TextFormat properties are null
by default because if you don't provide values for the properties, Flash
Player uses its own default formatting. The default formatting that Flash
Player uses for each property(if property's value is null
) is
as follows:
The default formatting for each property is also described in each property description.
Constructor
new (?font:String, ?size:Int, ?color:Int, ?bold:Bool, ?italic:Bool, ?underline:Bool, ?url:String, ?target:String, ?align:TextFormatAlign, ?leftMargin:Int, ?rightMargin:Int, ?indent:Int, ?leading:Int)
Creates a TextFormat object with the specified properties. You can then change the properties of the TextFormat object to change the formatting of text fields.
Any parameter may be set to null
to indicate that it is
not defined. All of the parameters are optional; any omitted parameters
are treated as null
.
Parameters:
font | The name of a font for text as a string. |
---|---|
size | An integer that indicates the size in pixels. |
color | The color of text using this text format. A number containing three 8-bit RGB components; for example, 0xFF0000 is red, and 0x00FF00 is green. |
bold | A Boolean value that indicates whether the text is boldface. |
italic | A Boolean value that indicates whether the text is italicized. |
underline | A Boolean value that indicates whether the text is underlined. |
url | The URL to which the text in this text format
hyperlinks. If |
target | The target window where the hyperlink is displayed. If
the target window is an empty string, the text is
displayed in the default target window
|
align | The alignment of the paragraph, as a TextFormatAlign value. |
leftMargin | Indicates the left margin of the paragraph, in pixels. |
rightMargin | Indicates the right margin of the paragraph, in pixels. |
indent | An integer that indicates the indentation from the left margin to the first character in the paragraph. |
leading | A number that indicates the amount of leading vertical space between lines. |
Variables
Indicates the alignment of the paragraph. Valid values are TextFormatAlign constants.
Throws:
ArgumentError | The |
---|
Indicates the block indentation in pixels. Block indentation is applied to
an entire block of text; that is, to all lines of the text. In contrast,
normal indentation(TextFormat.indent
) affects only the first
line of each paragraph. If this property is null
, the
TextFormat object does not specify block indentation(block indentation is
0).
Specifies whether the text is boldface. The default value is
null
, which means no boldface is used. If the value is
true
, then the text is boldface.
Indicates that the text is part of a bulleted list. In a bulleted list,
each paragraph of text is indented. To the left of the first line of each
paragraph, a bullet symbol is displayed. The default value is
null
, which means no bulleted list is used.
Indicates the color of the text. A number containing three 8-bit RGB
components; for example, 0xFF0000 is red, and 0x00FF00 is green. The
default value is null
, which means that Flash Player uses the
color black(0x000000).
The name of the font for text in this text format, as a string. The
default value is null
, which means that Flash Player uses
Times New Roman font for the text.
Indicates the indentation from the left margin to the first character in
the paragraph. The default value is null
, which indicates
that no indentation is used.
Indicates whether text in this text format is italicized. The default
value is null
, which means no italics are used.
A Boolean value that indicates whether kerning is enabled
(true
) or disabled(false
). Kerning adjusts the
pixels between certain character pairs to improve readability, and should
be used only when necessary, such as with headings in large fonts. Kerning
is supported for embedded fonts only.
Certain fonts such as Verdana and monospaced fonts, such as Courier New, do not support kerning.
The default value is null
, which means that kerning is not
enabled.
An integer representing the amount of vertical space(called
leading) between lines. The default value is null
,
which indicates that the amount of leading used is 0.
The left margin of the paragraph, in pixels. The default value is
null
, which indicates that the left margin is 0 pixels.
A number representing the amount of space that is uniformly distributed
between all characters. The value specifies the number of pixels that are
added to the advance after each character. The default value is
null
, which means that 0 pixels of letter spacing is used.
You can use decimal values such as 1.75
.
The right margin of the paragraph, in pixels. The default value is
null
, which indicates that the right margin is 0 pixels.
The size in pixels of text in this text format. The default value is
null
, which means that a size of 12 is used.
Specifies custom tab stops as an array of non-negative integers. Each tab
stop is specified in pixels. If custom tab stops are not specified
(null
), the default tab stop is 4(average character width).
Indicates the target window where the hyperlink is displayed. If the
target window is an empty string, the text is displayed in the default
target window _self
. You can choose a custom name or one of
the following four names: _self
specifies the current frame
in the current window, _blank
specifies a new window,
_parent
specifies the parent of the current frame, and
_top
specifies the top-level frame in the current window. If
the TextFormat.url
property is an empty string or
null
, you can get or set this property, but the property will
have no effect.
Indicates whether the text that uses this text format is underlined
(true
) or not(false
). This underlining is
similar to that produced by the <U>
tag, but the latter is
not true underlining, because it does not skip descenders correctly. The
default value is null
, which indicates that underlining is
not used.
Indicates the target URL for the text in this text format. If the
url
property is an empty string, the text does not have a
hyperlink. The default value is null
, which indicates that
the text does not have a hyperlink.
Note: The text with the assigned text format must be set with
the htmlText
property for the hyperlink to work.
