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 "emulation_layer.h" -#include "widget.h" -#include "TEScreen.h" -#include <stdio.h> -#include <stdlib.h> -#include <unistd.h> -#include <qkeycode.h> - - -/* ------------------------------------------------------------------------- */ -/* */ -/* EmulationLayer */ -/* */ -/* ------------------------------------------------------------------------- */ - -#define CNTL(c) ((c)-'@') - -/*! -*/ - -EmulationLayer::EmulationLayer(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()) ); -} - -/*! -*/ - -EmulationLayer::~EmulationLayer() -{ - delete screen[0]; - delete screen[1]; - bulk_timer.stop(); -} - -/*! change between primary and alternate screen -*/ - -void EmulationLayer::setScreen(int n) -{ - scr = screen[n&1]; -} - -void EmulationLayer::setHistory(bool on) -{ - screen[0]->setScroll(on); - if (!connected) return; - showBulk(); -} - -bool EmulationLayer::history() -{ - return screen[0]->hasScroll(); -} - -void EmulationLayer::setCodec(int c) -{ - //FIXME: check whether we have to free codec - codec = c ?
