Detailed Description

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.

type()

__init__()

Constructs a new length object which represents a variable size.

__init__(type, value)
Parameters:

  • type – Type

  • value – float

Constructs a new length object of the given type and value.

__ne__(other)
Parameters:

other – QTextLength

Return type:

bool

Returns true if this text length is different from the other text length.

__eq__(other)
Parameters:

other – QTextLength

Return type:

bool

Returns true if this text length is the same as the other text length.

rawValue()
Return type:

float

Returns the constraint value that is specific for the type of the length. If the length is PercentageLength then the raw value is in percent, in the range of 0 to 100. If the length is FixedLength then that fixed amount is returned. For variable lengths, zero is returned.

type()
Return type:

Type

Returns the type of this length object.

value(maximumLength)
Parameters:
