Detailed Description

template<typename T>
class cppcms::widgets::numeric< T >

Widget for number input. It is a template class that assumes that T is a number.

This class parses the input and checks if it is input text is a valid numeric value. If it is valid, the set() would return true be true.

If the value was not defined, access to value() will throw an exception.

Member Function Documentation

template<typename T>

virtual void cppcms::widgets::numeric< T >::clear ( )

inlinevirtual

Clear the form. It also calls set(false).

Reimplemented from cppcms::widgets::base_widget.

template<typename T>

void cppcms::widgets::numeric< T >::high ( T b )

inline

Set the maximum valid value.

template<typename T>

virtual void cppcms::widgets::numeric< T >::load ( http::context & context )

inlinevirtual

Load the widget data.

Implements cppcms::base_form.

References cppcms::http::context::locale(), cppcms::http::request::post_or_get(), and cppcms::http::context::request().

template<typename T>

void cppcms::widgets::numeric< T >::low ( T a )

inline

Set the minimum valid value.

template<typename T>

void cppcms::widgets::numeric< T >::non_empty ( )

inline

Inform the validator that this widget should contain some value.

template<typename T>

void cppcms::widgets::numeric< T >::range	(	T	a,
		T	b
	)

inline

Same as low(a); high(b);

template<typename T>

virtual void cppcms::widgets::numeric< T >::render_value ( form_context & context )

inlinevirtual

Render the first part of the widget.

Implements cppcms::widgets::base_html_input.

References cppcms::util::escape(), and cppcms::form_context::out().

template<typename T>

virtual bool cppcms::widgets::numeric< T >::validate ( )

inlinevirtual

Validate the widget.

Reimplemented from cppcms::widgets::base_widget.

template<typename T>

T cppcms::widgets::numeric< T >::value ( )

inline

Get numeric value that was loaded from the POST or GET data.

Note: if the value was not set (empty field for example) then this function will throw. So it is good idea to check if set() returns true before using this function.

template<typename T>

void cppcms::widgets::numeric< T >::value ( T v )

inline

Set the value of the widget.
