This class is responsible to scan the escapes sequences of the terminal emulation and to map it to their corresponding semantic complements. Thus this module knows mainly about decoding escapes sequences and is a stateless device w.r.t. the semantics. It is also responsible to refresh the Widget by certain rules. \sa Widget \sa Screen \par A note on refreshing Although the modifications to the current screen image could immediately be propagated via `Widget' to the graphical surface, we have chosen another way here. The reason for doing so is twofold. First, experiments show that directly displaying the operation results in slowing down the overall performance of emulations. 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 "widget_layer.h" #include "screen.h" #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <qkeycode.h> /* ------------------------------------------------------------------------- */ /* */ /* EmulationLayer */ /* */ /* ------------------------------------------------------------------------- */ #define CNTL(c) ((c)-'@') /*! */ -EmulationLayer::EmulationLayer(Widget* gui) +EmulationLayer::EmulationLayer( WidgetLayer* gui ) : decoder((QTextDecoder*)NULL) { this->gui = gui; - screen[0] = new Screen(gui->Lines(),gui->Columns()); - screen[1] = new Screen(gui->Lines(),gui->Columns()); + screen[0] = new Screen(gui->lines(),gui->columns()); + screen[1] = new Screen(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)), + QObject::connect(gui,SIGNAL( imageSizeChanged( 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( historyCursorChange( int ) ) ); + QObject::connect(gui,SIGNAL( keyPressed( QKeyEvent* ) ), this,SLOT(onKeyPress(QKeyEvent*))); - QObject::connect(gui,SIGNAL(beginSelectionSignal(const int,const int)), + QObject::connect(gui,SIGNAL( selectionBegin( const int, const int) ), this,SLOT(onSelectionBegin(const int,const int)) ); - QObject::connect(gui,SIGNAL(extendSelectionSignal(const int,const int)), + QObject::connect(gui,SIGNAL( selectionExtended( 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()), + QObject::connect(gui,SIGNAL( selectionEnd( const bool ) ), + this,SLOT( setSelection( const bool ) ) ); + QObject::connect(gui,SIGNAL( selectionCleared() ), 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 ?
