public class QTextLength
extends QtJambiObject
implements java.lang.Cloneable

The QTextLength class encapsulates the different types of length used in a QTextDocument. When we specify a value for the length of an element in a text document, we often need to provide some other information so that the length is used in the way we expect. For example, when we specify a table width, the value can represent a fixed number of pixels, or it can be a percentage value. This information changes both the meaning of the value and the way it is used.

Generally, this class is used to specify table widths. These can be specified either as a fixed amount of pixels, as a percentage of the containing frame's width, or by a variable width that allows it to take up just the space it requires.

Constructor Detail

QTextLength

public QTextLength()
Constructs a new length object which represents a variable size.


QTextLength

public QTextLength(QTextLength.Type type,
                   double value)
Constructs a new length object of the given type and value.

Method Detail

writeTo

public final void writeTo(QDataStream arg__1)
Writes thisQTextLength


readFrom

public final void readFrom(QDataStream arg__1)
Reads a QTextLength


rawValue

public final double rawValue()
Returns the constraint value that is specific for the type of the length. If the length is QTextLength::PercentageLength then the raw value is in percent, in the range of 0 to 100. If the length is QTextLength::FixedLength then that fixed amount is returned. For variable lengths, zero is returned.


type

public final QTextLength.Type type()
Returns the type of length.

See also:
QTextLength::Type .


value

public final double value(double maximumLength)
Returns the effective length, constrained by the type of the length object and the specified maximumLength.

See also:
type().


clone

public QTextLength clone()
This method is reimplemented for internal reasons

Overrides:
clone in class java.lang.Object
