Displaying + individual characters using X11 creates a lot of overhead. + + Second, by using the following refreshing method, the screen operations + can be completely separated from the displaying. This greatly simplifies + the programmer's task of coding and maintaining the screen operations, + since one need not worry about differential modifications on the + display affecting the operation of concern. + + We use a refreshing algorithm here that has been adoped from rxvt/kvt. + + By this, refreshing is driven by a timer, which is (re)started whenever + a new bunch of data to be interpreted by the emulation arives at `onRcvBlock'. + As soon as no more data arrive for `BULK_TIMEOUT' milliseconds, we trigger + refresh. This rule suits both bulk display operation as done by curses as + well as individual characters typed. + (BULK_TIMEOUT < 1000 / max characters received from keyboard per second). + + Additionally, we trigger refreshing by newlines comming in to make visual + snapshots of lists as produced by `cat', `ls' and likely programs, thereby + producing the illusion of a permanent and immediate display operation. + + As a sort of catch-all needed for cases where none of the above + conditions catch, the screen refresh is also triggered by a count + of incoming bulks (`bulk_incnt'). +*/ + +/* FIXME + - evtl. the bulk operations could be made more transparent. +*/ + +#include "TEmulation.h" +#include "TEWidget.h" +#include "TEScreen.h" +#include <stdio.h> +#include <stdlib.h> +#include <unistd.h> +#include <qkeycode.h> + + +/* ------------------------------------------------------------------------- */ +/* */ +/* TEmulation */ +/* */ +/* ------------------------------------------------------------------------- */ + +#define CNTL(c) ((c)-'@') + +/*! +*/ + +TEmulation::TEmulation(TEWidget* gui) +: decoder((QTextDecoder*)NULL) +{ + this->gui = gui; + + screen[0] = new TEScreen(gui->Lines(),gui->Columns()); + screen[1] = new TEScreen(gui->Lines(),gui->Columns()); + scr = screen[0]; + + bulk_nlcnt = 0; // reset bulk newline counter + bulk_incnt = 0; // reset bulk counter + connected = FALSE; + + QObject::connect(&bulk_timer, SIGNAL(timeout()), this, SLOT(showBulk()) ); + QObject::connect(gui,SIGNAL(changedImageSizeSignal(int,int)), + this,SLOT(onImageSizeChange(int,int))); + QObject::connect(gui,SIGNAL(changedHistoryCursor(int)), + this,SLOT(onHistoryCursorChange(int))); + QObject::connect(gui,SIGNAL(keyPressedSignal(QKeyEvent*)), + this,SLOT(onKeyPress(QKeyEvent*))); + QObject::connect(gui,SIGNAL(beginSelectionSignal(const int,const int)), + this,SLOT(onSelectionBegin(const int,const int)) ); + QObject::connect(gui,SIGNAL(extendSelectionSignal(const int,const int)), + this,SLOT(onSelectionExtend(const int,const int)) ); + QObject::connect(gui,SIGNAL(endSelectionSignal(const BOOL)), + this,SLOT(setSelection(const BOOL)) ); + QObject::connect(gui,SIGNAL(clearSelectionSignal()), + this,SLOT(clearSelection()) ); +} + +/*! +*/ + +TEmulation::~TEmulation() +{ + delete screen[0]; + delete screen[1]; + bulk_timer.stop(); +} + +/*! change between primary and alternate screen +*/ + +void TEmulation::setScreen(int n) +{ + scr = screen[n&1]; +} + +void TEmulation::setHistory(bool on) +{ + screen[0]->setScroll(on); + if (!connected) return; + showBulk(); +} + +bool TEmulation::history() +{ + return screen[0]->hasScroll(); +} + +void TEmulation::setCodec(int c) +{ + //FIXME: check whether we have to free codec + codec = c ?
