Class CalHTMLPreferences

    java.lang.Object
      |
      +--calpa.html.CalHTMLPreferences

public class CalHTMLPreferences
extends java.lang.Object
implements calpa.html.CalCons

A class used to control the default operation and rendering methods of a `CalHTMLPane`. The same `CalHTMLPreferences` object can be used with multiple panes. During construction all fields of the preferences object are set to default values. Individual fields can then be modified through the access methods listed.

Certain methods can only modify fields before the preferences object has been passed to a `CalHTMLPane`. Calling such methods after this point will not throw an exception - the calls are simply ignored.

Constructor Detail

### CalHTMLPreferences

    public CalHTMLPreferences()

  Creates a new `CalHTMLPreferences` object which will have all fields set to default values.

Method Detail

### getVisitedHash

    public java.util.Hashtable getVisitedHash()

  Returns a `Hashtable` containing references to visited `URLs`. This hashtable can be passed into a new `CalHTMLPreferences` object at a later date so that a user's visited links are persistent. The method of storing the hashtable's contents outside of this class is left to the programmer.

  The keys within the hashtable are all `Integer` objects, each representing a hashcode of a visited `URL` (note that this is not the hashcode returned from the `URL.hashcode()` method).
  The values within the hashtable are all `Long` objects representing the `System.currentTimeMillis()` when the link was last visited. The programmer may therefore remove 'old' links if so desired.

  Returns:
    a Hashtable recording visited document URLs
  See Also:
    `setVisitedHash(java.util.Hashtable)`

### setVisitedHash

    public void setVisitedHash(java.util.Hashtable table)

  Sets the `Hashtable` containing references to `URLs` which will be used by a `CalHTMLPane` to mark visited hyperlinks. Only pass in a hashtable which was previously obtained from a `CalHTMLPreferences` object via the `getVisitedHash()` method.
  Parameters:
    `table` - a Hashtable containing Integer/Long pairs representing visited document URLs
  See Also:
    `getVisitedHash()`

### setOptimizeDisplay

    public void setOptimizeDisplay(int optimizeLevel)

  Determines whether a `CalHTMLPane` will adjust display parameters based on frame width. The arguments which can be sent to this method are:

  - `CalCons.NO_OPTIMIZATION`
    No adjustments will be made for frame width. This is the default value.
  - `CalCons.OPTIMIZE_FONTS`
    Font size may be scaled based on frame width.
  - `CalCons.OPTIMIZE_ALL`
    In addition to font scaling, other parameters such as table cellspacing and cellpadding may be adjusted in an attempt to fit the document into the current frame.

  See the README.TXT file accompanying this document for more details on optimizeDisplay.

  Parameters:
    `optimizeLevel` - a value indicating the level (if any) of display optimization required
  See Also:
    `setFrameDisplayWidth(int, int)`, `setDefaultFont(int, int, int)`

### getOptimizeDisplay

    public int getOptimizeDisplay()

  Returns whether a `CalHTMLPane` will adjust display parameters based on frame size.

  See the README.TXT file accompanying this document for more details on optimizeDisplay.

  Returns:
    a value indicating the current level of display optimization

### setFrameDisplayWidth

    public void setFrameDisplayWidth(int displaySize,
                                     int width)

  Sets the width for the specified displaySize at which point a `CalHTMLPane` will start scaling its display if `optimizeDisplay` is enabled. The permitted displaySize arguments are:

  - `CalCons.S_SMALL`
  - `CalCons.S_MEDIUM`

  There is no need to set a width for displaySize `CalCons.S_LARGE` as a `CalHTMLPane` will treat any width greater than the `CalCons.S_MEDIUM` width as a large display.

  Default values are: `S_SMALL: 250 pixels, S_MEDIUM: 400 pixels`

  See the README.TXT file accompanying this document for more details on optimizeDisplay.

### getFrameDisplayWidth

    public int getFrameDisplayWidth(int displaySize)

  Returns the width for the specified displaySize at which point a `CalHTMLPane` will start scaling its display if `optimizeDisplay` is enabled. The permitted displaySize arguments are:

  - `CalCons.S_SMALL`
  - CalCons.S_MEDIUM

### setDefaultFont

    public void setDefaultFont(int displaySize,
                               int fontFamily,
                               int sizeIndex)

  Deprecated. Use `setDefaultFont(int, Font)` which allows the setting of system fonts.

### setDefaultFont

    public void setDefaultFont(int displaySize,
                               java.awt.Font font)

  Sets a default font to be used by a `CalHTMLPane`. This method takes three different size arguments:
  - `CalCons.S_SMALL`
  - CalCons.S_MEDIUM
  - CalCons.S_LARGE

  In most cases you will call this method with the `CalCons.S_LARGE` argument. The `S_SMALL` and `S_MEDIUM` arguments are used in special cases relating to printing (which is not yet supported in the Java 2 version of CalPane) and the `optimizeDisplay` feature of `CalHTMLPane`.

  This method replaces the now deprecated `setDefaultFont(int displaySize, int fontFamily, int sizeIndex)` method because Java 2 allows access to system fonts, rather than just Java's logical fonts.

  The font point sizes supported in CalPane are: 10, 11, 12, 13, 14, 16, 18, 20, 22, 24, 28, 36, 48

  If the size of the font sent to this method does not exactly match a supported size, then the closest supported value will be used.

  See Also:
    `setOptimizeDisplay(int)`

### getDefaultFont

    public java.awt.Font getDefaultFont(int displaySize)

  Returns a default font being used by a `CalHTMLPane`
  See Also:
    `setDefaultFont(int, java.awt.Font)`

                            int fontFamily,
                            int fontStyle,
                            int sizeArrayIndex)

  Deprecated. Use either `setDefaultButtonFont(int, Font)` or `setDefaultFormTextFont(int, Font)`.

### setDefaultButtonFont

    public void setDefaultButtonFont(int displaySize,
                                     java.awt.Font font)

  Sets a default font to be used within form Buttons and ComboBoxes. This method only applies to `THREEDEE` and `FLUSH` form components. `LOOKANDFEEL` components will not be affected. This method takes three different size arguments:

  - CalCons.S_MEDIUM
  - CalCons.S_LARGE

  In most cases you will call this method with the `CalCons.S_LARGE` argument. The `S_SMALL` and `S_MEDIUM` arguments are used in special cases relating to the `optimizeDisplay` feature of `CalHTMLPane`.

  The font point sizes supported in CalPane are: 10, 11, 12, 13, 14, 16, 18, 20, 22, 24, 28, 36, 48

### getDefaultColor

    public java.awt.Color getDefaultColor(int attributeType)

  Returns a default color used by a `CalHTMLPane` to render documents. See `setDefaultColor()` for allowed attributeTypes
  See Also:
    `setDefaultColor(int, java.awt.Color)`

### setFormRenderingStyle

    public void setFormRenderingStyle(int style)

  Sets the rendering style of `FORM` components within a `CalHTMLPane`. The permitted style values are:

  - `CalCons.USE_LOOK_AND_FEEL`
  - `CalCons.USE_CALPA_THREEDEE`
  - `CalCons.USE_CALPA_FLUSH`

  The `USE_LOOK_AND_FEEL` argument will use standard Swing components based on the currently installed Look&Feel. Generally these will provide an acceptable display, but with certain document background colors these components lose style features due to a clash between the background color of the document and the control, shadow, and highlight color of the component.

  The `USE_CALPA_THREEDEE` and `USE_CALPA_FLUSH` styles have been incorporated to help overcome such a situation. These components support author-specific color attributes which can be made to blend satisfactorily with the surrounding document color.

  Note that setting the default style via this method does not prevent the document author from setting individual styles within the document itself. Styles can be freely mixed by specifying style attributes within the relevant document form tags.

  Although this method can be called at any time during program execution, existing form components will remain in their original style.

  The default rendering style of form components is `USE_CALPA_THREEDEE`

  See the README.TXT file accompanying this document for more details on form rendering.

  Parameters:
    `style` - a value which determines the default rendering style of HTML form components

### getFormRenderingStyle

    public int getFormRenderingStyle()

  Returns the default rendering style of `FORM` components within a `CalHTMLPane`.
  Returns:
    a value indicating the default rendering style of HTML form components
  See Also:
