enaml.validator¶

Classes

class enaml.validator.FloatValidator[source]¶

Bases: enaml.validator.Validator

A concrete Validator which handles floating point input.

This validator ensures that the text represents a floating point number within a specified range.

minimum¶

The minimum value allowed for the float, inclusive, or None if there is no lower bound.

maximum¶

The maximum value allowed for the float, inclusive, or None if there is no upper bound.

allow_exponent¶

Whether or not to allow exponents like ‘1e6’ in the input.

validate(text)[source]¶

Validates the given text matches the float range.

Parameters :	text : unicode The unicode text edited by the client widget.
Returns :	result : bool True if the text is valid, False otherwise.

class enaml.validator.IntValidator[source]¶

Bases: enaml.validator.Validator

A concrete Validator which handles integer input.

This validator ensures that the text represents an integer within a specified range in a specified base.

minimum¶

The minimum value allowed for the int, inclusive, or None if there is no lower bound.

maximum¶

The maximum value allowed for the int, inclusive, or None if there is no upper bound.

base¶

The base in which the int is represented.

validate(text)[source]¶

Validates the given text matches the integer range.

Parameters :	text : unicode The unicode text edited by the client widget.
Returns :	result : bool True if the text is valid, False otherwise.

class enaml.validator.RegexValidator[source]¶

Bases: enaml.validator.Validator

A concrete Validator which handles text input.

This validator ensures that the text matches a provided regular expression string.

regex¶

The regular expression string to use for validation. The default regex matches everything.

validate(text)[source]¶

Validates the given text matches the regular expression.

Parameters :	text : unicode The unicode text edited by the client widget.
Returns :	result : bool True if the text is valid, False otherwise.

class enaml.validator.Validator[source]¶

Bases: atom.atom.Atom

The base class for creating widget text validators.

This class is abstract. It’s abstract api must be implemented by a subclass in order to be usable.

message¶

An optional message to associate with the validator. This message may be used by the toolkit to display information to the user about what went wrong.

validate(text)[source]¶

Validate the text as the user types.

This method is called on every keystroke to validate the text as the user inputs characters. It should be efficient. This is an abstract method which must be implemented by sublasses.

Parameters :	text : unicode The unicode text entered by the user.
Returns :	result : bool True if the text is valid, False otherwise.

fixup(text)[source]¶

An optional method to fix invalid user input.

This method will be called if user attempts to apply text which is not valid. This method may convert the text to a valid form. The returned text will be retested for validity. The default implementation of this method is a no-op.

Returns :	result : unicode The optionally modified input text.
