IlvHTMLText (Perforce JViews 10.0 API)

java.lang.Object
- ilog.views.IlvGraphic
- - ilog.views.graphic.IlvHTMLText

All Implemented Interfaces:

IlvPersistentObject, IlvBlinkingObject, IlvBaseTextDirectionInterface, Transferable, Serializable
```
public class IlvHTMLText
extends IlvGraphic
```
IlvHTMLText represents a piece of text specified as a HTML string.
Note: The setForeground method has no effect in this class. In order to set the text color, you can use
- Either the color style attribute of the <body> element. Example: <body style="color: #FF5010;">
- Or the text attribute of the <body> tag. Example: <body text="#FF5010">. (Deprecated.)
The default text color is black.
Note: The setBackground method has no effect in this class. In order to set the background color, you can use
- Either the background-color style attribute of the <body> element. Example: <body style="background-color: #663333;">
- Or the bgcolor attribute of the <body> tag. Example: <body bgcolor="#663333">. (Deprecated.)
The default background color is none, that is, transparent.
Limitations:
- This class does not support input elements (forms).
- The only transforms that it supports are zooms and translations. No shearing, no rotation.
- HTML constructs that are not supported by the Swing HTML renderer are not supported by this class either. For example:
  - Blinking through the CSS declaration text-decoration: blink is unsupported.
  - Changing the bidi base text direction of a piece of text through the attributes dir="rtl" or dir="ltr" is unsupported. Instead, you have to use the Unicode control characters LRE (‪), RLE (‫), and PDF (‬).
  - JavaScript, Flash, and applets are unsupported.
  - HTML 5 features (video, audio, and more) are unsupported.
Since:

JViews 8.8

- Constructor Detail
  - IlvHTMLText
```
public IlvHTMLText()
```
    Creates an initially empty HTML text.
  - IlvHTMLText
```
public IlvHTMLText(String htmlText)
```
    Creates a HTML text that displays a given HTML string.
    
    Parameters:
    
    htmlText - A string in HTML syntax. The <html> and <body> tags are optional.
  - IlvHTMLText
```
public IlvHTMLText(IlvInputStream stream)
            throws IlvReadFileException
```
    Creates an IlvHTMLText instance from the contents of an IlvInputStream.
    
    Parameters:
    
    stream - The input stream.
    
    Throws:
    
    IlvReadFileException - if the format is not correct.
- Method Detail
  - getHTMLText
```
public String getHTMLText()
```
    Returns the HTML string that is displayed by this IlvHTMLText object.
    
    Returns:
    
    A string.
  - setHTMLText
```
public void setHTMLText(String text)
```
    Sets the HTML string that is displayed by this IlvHTMLText object.
    
    Parameters:
    
    text - A string in HTML syntax. The <html> and <body> tags are optional.
  - isFractionalMetrics
```
public final boolean isFractionalMetrics()
```
    Returns true if the fractional metrics mode of the text is on. The default value is true. Setting it to false will speed up the IlvHTMLText but may lead to less precise text positioning.
  - setFractionalMetrics
```
public void setFractionalMetrics(boolean set)
```
    Changes the fractional metrics mode of the text. The default value is true. Setting it to false will speed up the IlvHTMLText but may lead to less precise text positioning.
    Note that this method call may change the bounding rectangle. For this reason, if the object is contained inside a manager, you should modify this flag using the applyToObject method of the manager.
  - isAntiAliasing
```
public final boolean isAntiAliasing()
```
    Returns true if the anti-aliasing mode of the text is on. The default value is false.
  - setAntiAliasing
```
public void setAntiAliasing(boolean set)
```
    Changes the anti-aliasing mode of the text. The default value is false.
    Note that this method call may change the bounding rectangle. For this reason, if the object is contained inside a manager, you should modify this flag using the applyToObject method of the manager.
  - getDefaultFont
```
public Font getDefaultFont()
```
    Returns the default font used for rendering text.
  - setDefaultFont
```
public void setDefaultFont(Font font)
```
    Changes the default font used for rendering text. The default value is a 12-point font.
    Note that this method call may change the bounding rectangle. For this reason, if the object is contained inside a manager, you should modify this flag using the applyToObject method of the manager.
  - getPageWidth
```
public double getPageWidth()
```
    Returns the page width. This is the maximum desired width of this object (in manager coordinates). Line breaking is used to enforce this page width. A width of 0 is interpreted as no limitation on width; it triggers no line breaking.
  - setPageWidth
```
public void setPageWidth(double pageWidth)
```
    Sets the page width. This is the maximum desired width of this object (in manager coordinates). Line breaking is used to enforce this page width. A width of 0 is interpreted as no limitation on width; it triggers no line breaking.
    The default value is 800.
    Note that this method call may change the bounding rectangle. For this reason, if the object is contained inside a manager, you should modify this flag using the applyToObject method of the manager.
  - getLeftMargin
```

```
    Sets the left margin of the box around the text. The default value is 0.
    Note that this margin is not filled with the background color. If you want a margin that is filled with the background color, use the margin-left and background-color style attributes of the <body> element. Example: <body style="background-color: #663333; margin-left:10px;">
    Note that this method call may change the bounding rectangle. For this reason, if the object is contained inside a manager you should modify the parameter using the applyToObject method of the manager.

```
public void setRightMargin(double margin)
```
    Sets the right margin of the box around the text. The default value is 0.
    Note that this margin is not filled with the background color. If you want a margin that is filled with the background color, use the margin-right and background-color style attributes of the <body> element. Example: <body style="background-color: #663333; margin-right:10px;">
    Note that this method call may change the bounding rectangle. For this reason, if the object is contained inside a manager you should modify the parameter using the applyToObject method of the manager.
