Detailed Description

This class is the real widget showing the document.

The other is a wrapper, that has the scrollbars... I'm not using QScrollView cause i've been having problems with that, and it's easier to do the work myself... Internally, this is basically a dumb class, which is manipulated by KigMode's. All events are forwarded to them.

Constructor & Destructor Documentation

KigWidget::KigWidget ( KigPart *  part,
KigView *  view,
QWidget *  parent = 0,
bool  fullscreen = false 
)

standard qwidget constructor.

This file is part of Kig, a KDE program for Interactive Geometry...

if fullscreen is true, we're a fullscreen widget.

Member Function Documentation

void KigWidget::clearStillPix ( )

The following are functions used by KigMode's to tell us to draw stuff...

i tried to optimise the drawing as much as possible, using much ideas from kgeo DOUBLE BUFFERING: we don't draw on the widget directly, we draw on a QPixmap ( curPix ), and bitBlt that onto the widget to avoid flickering. TRIPLE BUFFERING: we also currently keep an extra pixmap of what the widget looks like without objects that are moving... I'm currently wondering whether this isn't a performance loss rather than a gain, but well, i haven't done any measurements (yet ?), so for now it stays in... OVERLAYS Another thing: it turns out that working on the pixmaps isn't that slow, but working on the widget is. So we try to reduce the amount of work we spend on the widget. (i got this idea from kgeo, all credits for this go to marc..nosp@m.bart.nosp@m.sch@w.nosp@m.eb.d.nosp@m.e) on drawing, KigPainter tells us (appendOverlay) for everything it draws what rects it draws in, so we know on updating the widget ( updateWidget() that the rest is still ok and doesn't need to be bitBlt'd again on the widget... clear stillPix...

const Rect KigWidget::showingRect ( ) const

Mapping between Internal Coordinate Systems there are two coordinate systems: 1 the widget's coordinates: these are simple int's from (0,0) in the topleft of the widget to size() in the bottomRight...

2 the document's coordinates: these are the coordinates used by the KigDocument. Objects only know of their coordinates as related to this system. These are mapped by the KigView using the ScreenInfo class.
