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.

- class Type¶
This enum describes the different types a length object can have.
Constant
Description
QTextLength.VariableLength
The width of the object is variable
QTextLength.FixedLength
The width of the object is fixed
QTextLength.PercentageLength
The width of the object is in percentage of the maximum width

- __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
andvalue
.- __ne__(other)¶
- Parameters:
other –
QTextLength
- Return type:
bool
Returns
true
if this text length is different from theother
text length.- __eq__(other)¶
- Parameters:
other –
QTextLength
- Return type:
bool
Returns
true
if this text length is the same as theother
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 isFixedLength
then that fixed amount is returned. For variable lengths, zero is returned.Returns the type of this length object.

- value(maximumLength)¶
- Parameters:
maximumLength – float
- Return type:
float
Returns the effective length, constrained by the type of the length object and the specified
maximumLength
