Method Detail

showSource

public boolean showSource()

Instructs the viewer to display the HTML source.

Default returns showSource.

wrapLines

public boolean wrapLines()

Re-implementation returning true for rich text.

Overrides:

wrapLines in class TextView

quickLineHeight

public int quickLineHeight()

Allows optimised rendering by truncation of content to fit viewer size.

If the associated SViewer returns as SSelection.content() a String[] of lines, the viewer facet can optimise by only rendering a subset of these; to do so it needs an estimate of height of each line.

Returns:

by default -1 to signal no value; or estimated pixel height of each line
