Overview

Validator for text entries used for floating point numbers entry.

This validator can be used with Wx::TextCtrl or Wx::ComboBox (and potentially any other class implementing Wx::TextEntry interface) to check that only valid floating point values can be entered into them. Currently only fixed format is supported on input, i.e. scientific format with mantissa and exponent is not supported.

Similarly to Wx::IntegerValidator, the range for the accepted values is by default set appropriately for the type (double). Additionally, this validator allows to specify the maximum number of digits that can be entered after the decimal separator. By default this is also set appropriately for the type used, e.g. 15 for double on a typical IEEE-754-based implementation. As with the range, the precision can be restricted after the validator creation if necessary.

When the validator displays numbers with decimal or thousands separators, the characters used for the separators (usually “.” or “,”) depend on the locale set with Wx::Locale (note that you shouldn’t change locale with setlocale() as this can result in a mismatch between the separators used by Wx::Locale and the one used by the run-time library).

Examples:

A simple example of using this class:

class MyDialog < Wx::Dialog
  def initialize
    super(..)
    ...
    # Allow floating point numbers from 0 to 100 with 2 decimal
    # digits only and handle empty string as 0 by default.
    val = Wx::FloatValidator.new(2, Wx::NUM_VAL_ZERO_AS_BLANK)
    val.set_range(0, 100)

    # Associate it with the text control:
    Wx::TextCtrl.new(this, ..., val)
  end

end

Constructor Details

#initialize(style = Wx::NumValidatorStyle::NUM_VAL_DEFAULT) ⇒ Wx::FloatValidator #initialize(precision, style) ⇒ Wx::FloatValidator #initialize(other) ⇒ Wx::FloatValidator

Returns a new instance of FloatValidator.

Overloads:

  • #initialize(style = Wx::NumValidatorStyle::NUM_VAL_DEFAULT) ⇒ Wx::FloatValidator

    Constructor.

    Parameters:

    • style (Wx::NumValidatorStyle) (defaults to: Wx::NumValidatorStyle::NUM_VAL_DEFAULT) —

      A combination of Wx::NumValidatorStyle enum values.

  • #initialize(precision, style) ⇒ Wx::FloatValidator

    Constructor for validator specifying the precision.

    Parameters:

    • precision (Integer) —

      The number of decimal digits after the decimal separator to show and accept.

    • style (Wx::NumValidatorStyle) —

      A combination of Wx::NumValidatorStyle enum values.

  • #initialize(other) ⇒ Wx::FloatValidator

    Copy constructor.

    Parameters:

def initialize(*arg) end

Instance Method Details

#get_max ⇒ Float Also known as: max

Gets the maximum value accepted by the validator.

Returns:

  • (Float) 


329
 
# File 'lib/wx/doc/num_validator.rb', line 329

def get_max; end

#get_min ⇒ Float Also known as: min

Gets the minimal value accepted by the validator.

Returns:

  • (Float) 


317
 
# File 'lib/wx/doc/num_validator.rb', line 317

def get_min; end

#get_range ⇒ Array<Float,Float> Also known as: range

Gets both minimal and maximal values accepted by the validator.

Returns an array with [min, max]

Returns:

  • (Array<Float,Float>) 


344
 
# File 'lib/wx/doc/num_validator.rb', line 344

def get_range; end

#get_value ⇒ Float Also known as: value

Returns the value store attribute. Initially 0.

Returns:

  • (Float) 


377
 
# File 'lib/wx/doc/num_validator.rb', line 377

def get_value; end

#set_factor(factor) ⇒ Object Also known as: factor=

Set factor used for displaying the value.

The value associated with the validator is multiplied by the factor before displaying it and divided by it when retrieving its value from the control. By default, the factor is 1, so the actual value is not affected by it, but it can be set to, for example, 100, to display the value in percents while still storing it as absolute value.

Parameters:

  • factor (Float) 


372
 
# File 'lib/wx/doc/num_validator.rb', line 372

def set_factor(factor) end

#set_max(max) ⇒ Object Also known as: max=

Sets the maximal value accepted by the validator.

This value is inclusive, i.e. the value equal to max is accepted.

Parameters:

  • max (Float) 


324
 
# File 'lib/wx/doc/num_validator.rb', line 324

def set_max(max) end

#set_min(min) ⇒ Object Also known as: min=

Sets the minimal value accepted by the validator.

This value is inclusive, i.e. the value equal to min is accepted.

Parameters:

  • min (Float) 


312
 
# File 'lib/wx/doc/num_validator.rb', line 312

def set_min(min) end

#set_precision(precision) ⇒ Object Also known as: precision=

Set precision.

Precision is the number of digits shown (and accepted on input) after the decimal point. By default this is set to the maximal precision supported by the type handled by the validator in its constructor.

Parameters:

  • precision (Integer) 


361
 
# File 'lib/wx/doc/num_validator.rb', line 361

def set_precision(precision) end

#set_range(min, max) ⇒ Object Also known as: range=

Sets both minimal and maximal values accepted by the validator.

Calling this is equivalent to calling both #set_min and #set_max.

Parameters:

  • min (Float)
  • max (Float) 


337
 
# File 'lib/wx/doc/num_validator.rb', line 337

def set_range(min, max) end

#set_style(style) ⇒ Object Also known as: style=

Change the validator style.

Can be used to change the style of the validator after its creation.

Parameters:



351
 
# File 'lib/wx/doc/num_validator.rb', line 351

def set_style(style) end

#set_value(val) ⇒ Object Also known as: value=

Sets the value store attribute.

Parameters:

  • val (Float) 


382
 
# File 'lib/wx/doc/num_validator.rb', line 382

def set_value(val) end
