Detailed Description

class html_form_input implements HTML input feature

it is expected to be adopted by an html_form directory or through an html_form_fieldset, to provide a mean for user to provide information. Depdending on the type set in the constructor argument, this object is visually a text window, a check box or let the user select a file on his local directory (local from browser point of view).

Examples: /home/denis/Webdar/webdar/src/html_form_input_file.hpp.

Constructor & Destructor Documentation

◆ html_form_input()

html_form_input::html_form_input	(	const std::string &	label,
		input_type	type,
		const std::string &	initial_value,
		const std::string &	size,
		const std::string &	css_class
	)

Parameters

label	label beside the input
type	type of input
initial_value	for check set empty string for unchecked, anything else for checked
size	the size in the HTML component is not resizeable use "" to not use it
css_class	a CSS class with "max-width/width/min-width" properties is reactive and better than size

◆ set_change_event_name()

void html_form_input::set_change_event_name ( const std::string & name )

change the name of the event generated when this control changes

Parameters

[in] name must not be an empty string

Note: all actors already recorded on the changed event will be kept registered on this new event name. The old event will no more be triggered In consequences actor should be aware of the event name change asked to this component here.; this call can be used any number of time, all actors will be kept
