###### 20.8.1.4.2 Specifying link properties via window-access object

You can specify a button, a text string, or a graphic for JavaHelp 2 to display as a window-access object for a pop-up link or a secondary-window jump. If you specify a text string, you can assign values to font keywords to apply a limited amount of formatting. Table 20-2 lists the base keywords, and the values you can assign to those keywords, to configure the appearance of a window-access object.

Prefix base keywords with “Pop” or “Sec”

You must supply a prefix for each of the object-property base keywords listed in Table 20-2, to indicate whether the keyword represents a property for a pop-up window link or for a secondary-window jump:

- For a pop-up window, prefix the keyword with Pop; for example:

      [JavaHelp window name]
      PopType = Graphic
      PopGraphic = ../graphics/popicon.gif

- For a secondary window, prefix the keyword with Sec; for example:

      [JavaHelp window name]
      SecType = Button

Table 20-2 [JavaHelp window name] window-access object properties

Keyword* | Value | Default value and comments
    Type
    Button
    Graphic
    Text
| When Type=Button (default), the value of keyword Text is the label When Type=Graphic, the value of keyword Text (or keyword Graphic) is the location of the image file When Type=Text, Font* properties apply to the value of keyword Text
    Graphic
| URL for image file | Default is ../graphics/1p.gif When Type=Graphic, value is the relative URL of the GIF or JPEG file
    Text
| plain text
    &lt;
    &gt;
    &amp;
| Default is &gt; When Type=Text, Font* properties apply to the value of keyword Text When Type=Graphic, value can be the location of the image (which can be specified as a value either for keyword Text or for keyword Graphic)
    FontFamily
    SansSerif
    Serif
    Monospaced
    Symbol
    Dialog
    DialogInput
| Pop-up window default is SansSerif Secondary window default is Serif Not all FontFamily values work the way you might expect them to work
    FontSize
| xx-small, x-small, small (default), medium, large, x-large
    index number
    bigger
    smaller
    +n
    -n
    nnpt
| index number is a plain digit bigger increases the size by one index smaller decreases the size by one index +n increases the size by n -n decreases the size by n nnpt specifies the font size in points
    FontWeight
| plain (default), bold
    FontStyle
| plain (default), italic
    FontColor
| blue (default), black, cyan, darkGray, gray, green, lightGray, magenta, orange, pink, red, white, yellow
* Prefix the base keyword with one of the following: Pop for a pop-up window property Sec for a secondary-window property

Eschew Type=Text

Despite the limited font-tweaking possibilities listed in Table 20-2, you might want to avoid setting PopType=Text or SecType=Text, unless you are happy with a link that consists of a single >, <, or & character, or a little box (what you get when, for example, you specify PopFontFamily=Symbol and choose a character from the Symbol font). See §20.8.1.3 Understanding JavaHelp 2 window-access limitations.

Multiple markers for each hotspot

To actually create a text hotspot with context-specific content, you would have to insert a collection of markers, all different, before every pop-up link or secondary-window jump in a file, to handle the varying text content and properties—to the limited extent that you can do so. See §20.8.1.5 Overriding window-access properties with markers.

Not all “special” characters work

Keep in mind that JavaHelp does not support the “undefined” characters with ASCII decimal values from 128 through 159, even though these characters are used heavily in Windows for quotes, bullets, and so forth.
