Detailed Description

Provides an xterm compatible terminal emulation based on the DEC VT102 terminal.

A full description of this terminal can be found at http://vt100.net/docs/vt102-ug/

In addition, various additional xterm escape sequences are supported to provide features such as mouse input handling. See http://rtfm.etla.org/xterm/ctlseq.html for a description of xterm's escape sequences.

void Emulation::lockPtyRequest ( bool suspend )

signalinherited

Requests that sending of input to the emulation from the terminal process be suspended or resumed.

Parameters

suspend If true, requests that sending of input from the terminal process' stdout be suspended. Otherwise requests that sending of input be resumed.

void Vt102Emulation::onScrollLock ( )

private

void Emulation::outputChanged ( )

signalinherited

Emitted when the contents of the screen image change.

The emulation buffers the updates from successive image changes, and only emits outputChanged() at sensible intervals when there is a lot of terminal activity.

Normally there is no need for objects other than the screen windows created with createWindow() to listen for this signal.

ScreenWindow objects created using createWindow() will emit their own outputChanged() signal in response to this signal.

Referenced by Emulation::createWindow(), and Emulation::showBulk().

void Emulation::profileChangeCommandReceived ( const QString & text )

signalinherited

Emitted when the terminal program requests to change various properties of the terminal display.

A profile change command occurs when a special escape sequence, followed by a string containing a series of name and value pairs is received. This string can be parsed using a ProfileCommandParser instance.

Parameters

text	A string expected to contain a series of key and value pairs in the form: name=value;name2=value2 ...

bool Emulation::programUsesMouse ( ) const

inherited

Returns true if the active terminal program wants mouse input events.

The programUsesMouseChanged() signal is emitted when this changes.

void Emulation::programUsesMouseChanged ( bool usesMouse )

void Emulation::receiveData	(	const char *	buffer,
		int	len
	)

slotinherited

Processes an incoming stream of characters.

receiveData() decodes the incoming character buffer using the current codec(), and then calls receiveChar() for each unicode character in the resulting buffer.

receiveData() also starts a timer which causes the outputChanged() signal to be emitted when it expires. The timer allows multiple updates in quick succession to be buffered into a single outputChanged() signal emission.

Parameters

buffer	A string of characters received from the terminal program.
len	The length of `buffer`

virtualslot

Mouse clicks are possibly reported to the client application if it has issued interest in them. They are normally consumed by the widget for copy and paste, but may be propagated from the widget when gui->setMouseMarks is set via setMode(MODE_Mouse1000).

`x',`y' are 1-based. `ev' (event) indicates the button pressed (0-2) or a general mouse release (3).

eventType represents the kind of mouse action that occurred: 0 = Mouse button press or release 1 = Mouse drag

void Emulation::titleChanged	(	int	title,
		const QString &	newTitle
	)

signalinherited

Emitted when the program running in the terminal wishes to update the session's title.

This also allows terminal programs to customize other aspects of the terminal emulation display.

This signal is emitted when the escape sequence "\033]ARG;VALUE\007" is received in the input string, where ARG is a number specifying what should change and VALUE is a string specifying the new value.

TODO: The name of this method is not very accurate since this method is used to perform a whole range of tasks besides just setting the user-title of the session.

Parameters

title

Specifies what to change.

0 - Set window icon text and session title to newTitle
1 - Set window icon text to newTitle
2 - Set session title to newTitle
11 - Set the session's default background color to newTitle, where newTitle can be an HTML-style string (#RRGGBB) or a named color (eg 'red', 'blue'). See http://doc.trolltech.com/4.2/qcolor.html#setNamedColor for more details.
31 - Supposedly treats newTitle as a URL and opens it (NOT IMPLEMENTED)
32 - Sets the icon associated with the session. newTitle is the name of the icon to use, which can be the name of any icon in the current KDE icon theme (eg: 'konsole', 'kate', 'folder_home')

newTitle Specifies the new title
