HTMLStyleGetProperties Function

Overview

The HTMLStyleGetProperties function returns the style properties for the current buffer or part of the buffer.

Syntax/Parameters

Syntax

string[] = HTMLStyleGetProperties ( handle hStyle, [int start], [int end] );

Parameters

hStyle

A handle to an HTML Style Object.

start

An optional int specifying the zero-based position to start rendering from. If omitted, the default value is -1 (same as zero starting from the beginning).

end

An optional int specifying the zero-based position to start rendering from. If omitted, the default value is -1, indicating to return data to the end of the buffer, or if start is provided, this at the start position.

Return Value

A string array containing the style properties or an empty array on failure. Use the GetLastError function to retrieve a formatted error code.

Remarks

The function looks at each character position within the styled text and returns an aggregate of the style data. Note that the tags that lead to the text being styled are not part of the text buffer and do not count toward the position. For example, the following text is added:

The is <b>bold</b> text.

It is internally as represented as:

The is bold text.

Therefore, the start position of ‘b’ is 7.

The returned string array uses lower case versions of the CSS property names as key names.

	font-family		Font name.
	font-size		Size as specified.
	font-weight		Weight, including the <b> tag.
	font-stretch		Stretch keyword.
	font-style		Style as normal or italic, including the <i> tag.
	font-variant		Small caps.
	text-decoration-line		Type of line on text, including underline including <u> tag.
	text-decoration-color		Line color.
	text-decoration-style		Line style. Conflicts with text-underline-style.
	text-transform		Capital, lower and upper case.
	text-underline-style		Underline style (note, as part of CSS, this conflicts with text-decoration-style but included for compatibility).
	color		Text color.
	letter-spacing		Letter spacing.
	line-height		Line height.
	vertical-align		Vertical align.
	word-spacing		Word spacing.
	background-color		Background color.

 

If an item is not set, the element’s value is an empty string. If there are conflicting style states with the range of the buffer, the element will have the term, “(mixed)”, in the key array position.

The start and end positions must be range within the end of the text buffer (not the coded area). If only the start position is supplied, then the function will return a snapshot of that x position within the buffer.
