	@keyterms:
		lineedit object class, line editor, input
	@title:
		lineedit class
	@type:
		class
	@short:
		Simple line editor for inputting short text
	@inherits:
		[class]object[/class]
		[class]widget[/class]
	@description:
		This is a simple, one-line editor usually used for inputting
		short text like names, phone numbers etc. It can display text
		in three echo modes (see [classfnc]$setEchoMode[/classfnc]()
		for details).
	@functions:
		!fn: <string> $text()
		Returns text contained by the widget.[br]
		See also [classfnc]$setText[/classfnc]().
		!fn: $setText(<text:string>)
		Sets editor text to <text>.[br]
		See also [classfnc]$text[/classfnc]().
		!fn: $setEchoMode(<echo_mode:string>)
		Sets the line edit's echo mode. Possible value are:[br]
		-Normal: display chars as they entered[br]
		-Noecho : do not display anything[br]
		-Password : display asterisks instead of the characters actually entered[br]
		See also [classfnc]$echoMode[/classfnc]().
		!fn: <string> $echoMode()
		Return the line edit's echo mode.
		See also [classfnc]$setEchoMode[/classfnc]().
		!fn: <integer> $maxLength()
		Returns the current maximum length of the text that can be typed
		 in the editor.[br]
		See also [classfnc]$setMaxLength[/classfnc]().
		!fn: $setMaxLength(<max_lenght:integer>)
		Sets maximum length of the text that can be typed in the
		editor.[br]
		See also [classfnc]$maxLength[/classfnc]().
		!fn: <boolean> $frame()
		Returns '1' if the editor is drawn inside a frame, which is 2
		pixels wide, '0' otherwise.[br]
		See also [classfnc]$setFrame[/classfnc]().
		!fn: $setFrame(<bframe:boolean>)
		Sets editor frame drawing to <bool>.[br]
		See also [classfnc]$frame[/classfnc]().
		!fn: <integer> $cursorPosition()
		Returns current cursor position in the editor.[br]
		See also [classfnc]$setCursorPosition[/classfnc]().
		!fn: $setCursorPosition(<index:integer>)
		Moves the cursor to place pointed by <index>.[br]
		See also [classfnc]$cursorPosition[/classfnc]().
		!fn: $selectAll()
		Selects whole text inside the editor.[br]
		See also [classfnc]$setSelection[/classfnc](),
		[classfnc]$cut[/classfnc](), [classfnc]$copy[/classfnc](),
		[classfnc]$paste[/classfnc]().
		!fn: $setSelection(<start:integer>, <length:integer>)
		Selects <length> characters in the editor starting at position
		<start>.[br]
		See also [classfnc]$selectAll[/classfnc](),
		[classfnc]$cut[/classfnc](), [classfnc]$copy[/classfnc](),
		[classfnc]$paste[/classfnc]().
		!fn: $copy()
		Copies selected text in the editor to the clipboard.[br]
		See also [classfnc]$setSelection[/classfnc](),
		[classfnc]$cut[/classfnc](), [classfnc]$paste[/classfnc]().
		!fn: $cut()
		Cuts selected text from the editor to the clipboard.[br]
		See also [classfnc]$setSelection[/classfnc](),
		[classfnc]$copy[/classfnc](), [classfnc]$paste[/classfnc]().
		!fn: $paste()
		Pastes text from the clipboard into the editor. The pasted text
		will start at cursor position.[br]
		See also [classfnc]$setSelection[/classfnc](),
		[classfnc]$copy[/classfnc](), [classfnc]$cut[/classfnc]().
		!fn: $clear()
		Deletes all text from the editor. Equal to calling [classfnc]$setText[/classfnc]("").
		!fn: $setDragEnabled(<bEnabled:bool>)
		With this property user can drag text in the lineedit.
		!fn: $setReadOnly(<bReadonly:boolean>)
		Sets the lineedit to read only mode.
		!fn: $setInputMask(<mask:string>)
		Sets the validation input mask to inputMask.[br]
		Example:[br]
		[br]
		%esempio->$setInputMask( "+99 99 99 99 99;_" );[br]
		%esempio->$setInputMask( "000.000.000.000;_" );[br]
		%esempio->Ip Number Mask.[br]
		%esempio->setInputMask( ">AAAAA-AAAAA-AAAAA-AAAAA-AAAAA;#" );[br]
		[br]
		The mask format understands these mask characters:[br]
		Character		Meaning[br]
		A			ASCII alphabetic character required. A-Z, a-z.[br]
		a			ASCII alphabetic character permitted but not required.[br]
		N			ASCII alphanumeric character required. A-Z, a-z, 0-9.[br]
		n			ASCII alphanumeric character permitted but not required.[br]
		X			Any character required.[br]
		x			Any character permitted but not required.[br]
		9			ASCII digit required. 0-9.[br]
		0			ASCII digit permitted but not required.[br]
		D			ASCII digit required. 1-9.[br]
		d			ASCII digit permitted but not required.[br]
		#			ASCII digit or plus/minus sign permitted but not required.[br]
		>			All following alphabetic characters are uppercased.[br]
		<			All following alphabetic characters are lowercased.[br]
		!			Switch off case conversion.[br]
		\			Use \ to escape the special characters listed above to use them as separators.[br]
		[br]
		The mask consists of a string of mask characters and separators, optionally[br]
		followed by a semi-colon and the character used for blanks: the blank characters [br]
		are always removed from the text after editing. The default blank character is space. [br]
		!fn: $returnPressedEvent()
		This function is called by the framework when the enter key is pressed.
		!fn: $lostFocusEvent()
		Called when the lineedit lost focus.
		!fn: $textChangedEvent(<new text:string>)
		This event is called when the text changed, In $0 there is the new text.
	@signals:
		!sg: $returnPressed()
		This signal is emitted by the default implementation of [classfnc]$returnPressedEvent[/classfnc]().
		!sg: $lostFocus()
		This signal is emitted by the default implementation of [classfnc]$lostFocusEvent[/classfnc]().
		!sg: $textChanged()
		This signal is emitted by the default implementation of [classfnc]$textChangedEvent[/classfnc]().
