Horizontal and Vertical Spacing · Hypertext · Images
Reset · Strikethrough Text · Underlined Text
Most JClass BWT components support a rich text format called "JCString", which allows a mixture of hypertext, images and text within BWT components. Text can also appear in a variety of colors, fonts and styles, including underline and strikeout.
The following section describes the types of JCString properties available, and provides examples of their use.
If a cell contains an image, the line height can, in some cases,
be greater than the height of the text. Text can be aligned vertically
using the ALIGN property. Valid values include TOP, BOTTOM and MIDDLE. The following example uses
all three possible ALIGN values:
([IMAGE=smiley.gif][ALIGN=TOP]top [IMAGE=smiley.gif][ALIGN=MIDDLE]middle
[IMAGE=smiley.gif][ALIGN=bottom]bottom)
Different
text colors can be specified by using the COLOR
property. The JCString shown below displays text using red, green
and blue colors.
([COLOR=red]Red, [COLOR=green]Green, [COLOR=blue]Blue, [DEFAULT_COLOR]Default)
In addition to these colors, any color referenced in Appendix E can be used, including RGB color values.
Note: The property
DEFAULT_COLOR resets the text color in the rest of the table to
the browser's regular text color.
Different
fonts can be specified within a single cell or label by using
the FONT property. The following
JCString example displays text using a variety of fonts and font
styles.
([FONT=timesroman-plain-20]TimesRoman-20, [FONT=timesroman-bold-12]TimesRoman-12 bold,
[DEFAULT_FONT]Default)
Note: The property DEFAULT_FONT
resets the fonts in the rest of the table to the browser's regular
font.
Vertical and horizontal spacing
can be modified by using the VERT_SPACE and HORIZ_SPACE
tags. VERT_SPACE offsets the
current line by a number of pixels, and HORIZ_SPACE offsets the
line from the margin by a set number of pixels. The example below
makes use of the HORIZ_SPACE and VERT_SPACE. tags.
([VERT_SPACE=10]Vertical offset=10
[HORIZ_SPACE=10] Horizontal offset=10)
Hypertext
links can be specified within a cell. The link appears underlined,
and the browser display will show the target URL when the mouse
cursor passes over the linked text. Hypertext uses the HREF
property, and trackCursorPosition must be set to true in order
for the link to work. The example below links to KL Group's home
page:
(Click [HREF=http://www.klg.com]here[/HREF] for tech
support \n [HREF=http://www.klg.com]
[IMAGE=http://www.klg.com/images/technical.gif][HREF])
Images
can be specified in a cell by using the IMAGE
property. A URL or file name must be provided. If a relative path
is given, the document base for the page is assumed. The example
below mixes an image with text.
(Tech Support: [IMAGE=http://www.klg.com/images/technical.gif])
The RESET property resets the font and
color to the default value used by the browser. The following
example changes the COLOR and FONT values back to the default:
([COLOR=green][FONT=timesroman-plain-20]Big text [RESET]Regular Text)
Text can be crossed-out using the STRIKEOUT
property. The following incorporates text that has been stuck
through:
(This text is [ST]crossed-out[/ST].)
Text can be underlined using the JCString UNDERLINE
property. The following example incorporates underlined lined
text:
(This text is [UL]underlined[/UL].)
