org.eclipse.jface.text.IBlockTextSelection

A rectangular selection in a text document. A column selection spans the visually identical range of columns on a contiguous range of lines. The character count of the same visually perceived column may not be equal for two different lines, therefore computing the set of disjunct character ranges covered by a column selection is influenced by the used font and tabulator width. Using column selections with proportional fonts may render unexpected results.

Virtual Spaces

The {@linkplain #getStartColumn() start column} and {@linkplain #getEndColumn() end column} mayrefer to "virtual offsets" in the white space beyond the end of the line. Such an offset can be realized by inserting a space for each missing character.

The {@linkplain ITextSelection#getOffset() offset} and{@linkplain ITextSelection#getLength() length} of an {@link IBlockTextSelection} refer to thesmallest non-virtual range that comprises the entire rectangular selection.

Clients may implement this interface or use the default implementation provided by {@link org.eclipse.jface.text.BlockTextSelection}.
