HTML support for form controls


Buttons, check boxes, radio buttons, check groups, and label controls all support a "mini" subset of HTML

This enhances the usability of these controls. For example:

1. Ability to add pictures
2. Ability to have multi line captions
3. Ability to have different color text (and font etc) for separate lines/words
4. Ability to have "colored" buttons
5. Ability to have "hyper links" inside captions

With a bit of imagination I am sure you will see others 

For example, if you wanted a yellow button then the button caption would be something like:
 

<BODY bgcolor="clYellow"><P align="center"><br>Yellow button<br><br></p>

 
  

And to show an image on a button the code would be something like:
 

<P align="center"><IMG src="file://c:\temp\hq.gif" align="middle"> HQ cache</p>



 
However, in most cases you probably won't want to use explicit file paths for your images, as other users of your macro won't necessarily have the same folder structure as you. GSAK supports the use of the two system variables $_AppData and $_ExePath in control captions.

So you would normally use GSAK system variables to reference your images. You would then update your caption property in your control accordingly. So let us say the image file "hq.gif" is in your "Macros" folder, then your button caption would be:
 

<P align="center"><IMG src="file://$_AppData\Macros\hq.gif" align="middle"> HQ cache</p>

 
The min subset of  HTML support includes :
 

B : Bold tag
<B> : start bold text
</B> : end bold text

Example : This is a <B>test</B>

U : Underline tag
<U> : start underlined text
</U> : end underlined text

Example : This is a <U>test</U>

I : Italic tag
<I> : start italic text
</I> : end italic text

Example : This is a <I>test</I>

S : Strikeout tag
<S> : start strike-through text
</S> : end strike-through text

Example : This is a <S>test</S>

A : anchor tag
<A href="value"> : text after tag is an anchor. The 'value' after the href identifier is the anchor. This can be an URL (with ftp,http,mailto,file identifier) or any text.

Examples : This is a <A href= "mailto:myemail@mail.com ">test</A>
This is a <A href="http://www.gsak.net">test</A>

FONT : font specifier tag
<FONT face='facevalue' size='sizevalue' color='colorvalue' bgcolor='colorvalue'> : specifies font of text after tag.
with

   * face : name of the font
   * size : HTML style size if smaller than 5, otherwise pointsize of the font
   * color : font color with either hexadecimal color specification or Borland style color name, ie clRed,clYellow,clWhite ... etc
   * bgcolor : background color with either hexadecimal color specification or Borland style color name </FONT> : ends font setting

Examples : This is a <FONT face="Arial" size="12" color="clred">test</FONT>
This is a <FONT face="Arial" size="12" color="#FF0000">test</FONT>

P : paragraph
<P align="alignvalue" [bgcolor="colorvalue"] [bgcolorto="colorvalue"]> : starts a new paragraph, with left, right or center alignment. The paragraph background color is set by the optional bgcolor parameter. If bgcolor and bgcolorto are specified,
a gradient is displayed ranging from begin to end color.
</P> : end of paragraph

Example : <P align="right">This is a test</P>
Example : <P align="center">This is a test</P>
Example : <P align="left" bgcolor="#ff0000">This has a red background</P>
Example : <P align="right" bgcolor="clYellow">This has a yellow background</P>
Example : <P align="right" bgcolor="clYellow" bgcolorto="clred">This has a gradient background</P>*

HR : horizontal line
<HR> : inserts linebreak with horizontal line

BR : linebreak
<BR> : inserts a linebreak

BODY : body color / background specifier
<BODY bgcolor="colorvalue" [bgcolorto="colorvalue"] [dir="v|h"] background="imagefile specifier"> : sets the background color of the HTML text or the background bitmap file

Example : <BODY bgcolor="clYellow"> : sets background color to yellow
<BODY background="file://c:\test.bmp"> : sets tiled background to file test.bmp
<BODY bgcolor="clYellow" bgcolorto="clWhite" dir="v"> : sets a vertical gradient from yellow to white

IND : indent tag
This is not part of the standard HTML tags but can be used to easily create multicolumn text
<IND x="indent"> : indents with "indent" pixels

Example :
This will be <IND x="75">indented 75 pixels.

IMG : image tag
<IMG src="file://" [align="Top|Middle|Bottom"] [width="width"] [height="height"]  > : inserts an image at the location

Supported image types: BMP, GIF (png is supposed to be supported but I get "unsupported image format when I tested this)
Optionally, an alignment tag can be included. If no alignment is included, the text alignment with respect to the image is bottom. Other possibilities are : align="top" and align="middle"
The width & height to render the image can be specified as well. 
Example : This is an image <IMG src="file://c:\my documents\test.bmp">


SUB : subscript tag
<SUB> : start subscript text
</SUB> : end subscript text

Example : This is <SUP>9</SUP>/<SUB>16</SUB> looks like 9/16

SUP : superscript tag
<SUP> : start superscript text
</SUP> : end superscript text

Example : This is <FONT color="clred"><BLINK>blinking red</BLINK></FONT>text.

UL : list tag
<UL> : start unordered list tag
</UL> : end unordered list

Example : <UL>
<LI>List item 1
<LI>List item 2
<UL>
<LI> Sub list item A
<LI> Sub list item B
</UL>
<LI>List item 3
</UL>

LI : list item
<LI [type="specifier"] [color="color"] [name="imagename"]> : new list item
specifier can be "square" or "circle".  bullet color sets the color of the square or circle bullet.

SHAD : text with shadow
<SHAD> : start text with shadow
</SHAD> : end text with shadow

Z : hidden text
<Z> : start hidden text
</Z> : end hidden text

HI : highlight
<HI> : start text highlighting
</HI> : stop text highlighting

E : Error marking
<E> : start error marker
</E> : stop error marker
