That is doable, though those values would have to be specified as
strings, since "size:+1" isn't valid JSON. But that is OK, since that
makes it easier to handle those cases. If size is a number, it is
handled as a point size. Otherwise, if it is a string and begins with
"+" or "-", we can treat it as a increment or decrement value. If it
ends with "%", we would treat it as a percentage value.
On the other hand, "+1" is somewhat vague. What units would apply
here? Does the value represent a point size? If so, then you'd still
need to know something about the default font to know how "1" relates
to it. Maybe a strictly relative format (such as percentage) would be
better.

Hi
Since font sizing is also generally part of the theme, is would be
nice to be able to specify
styles="font:{size:+1}"
or
styles="font:{size:120%}"
so that no knowledge of the theme's settings is necessary.

Hi all,
I have just finished making a change that provides much more
flexibility in
customizing the appearance of text-based components. Instead of the
"fontBold", "fontItalic", and "fontSize" styles that were
previously limited
to the Label skin, you can now use a new JSON-based encoding on any
component that displays text. For example, the following markup
will create
a PushButton that uses a 12-point bold font whose other attributes
are taken
from the theme font:
<PushButton buttonData="Foo" styles="{font:{size:12, bold:true}}"/>
All properties are optional; any unspecified properties will be
taken from
the theme. The supported attributes are "name" (String),
"size" (int),
"bold" (boolean), and "italic" (boolean). Note that, if the curly
braces are
not included, the previous encoding that relied on Font.decodeFont
() will be
used.
The down side is that you will need to update any WTKX files that
were using
the previous styles, since they are no longer supported. Any such
changes
should be straightforward, but please let me know if you have any
questions.
Greg
