When stroking a - rectangle of width 10, the pen would draw a rectangle of width 10. - Drawing a polygon defined by the corner points of the same - rectangle the stroke would have a width of 11. - - The reason for this is best explained using the picture below: - - \img q3painter_rationale.png - - As we can see, stroking the rectangle so it gets a width of 10, - means the pen is drawn on a rectangle on width 9. The polygon, - however follows a consistent model. - - In Qt 4, all rectangle based functions have changed to follow the - polygon approach, which means that the rectangle defines the size of - the fill, and the pen follows the edges of the shape. For pen widths - of 0 and 1 this means that the stroke will be inside the shape on the - left and the top and outside on the bottom and right. - - The reason for the change in Qt 4 is so that we provide consistency - for all drawing functions even with complex transformations. -*/ - -TQPainter::TQPainter() : QPainter(), has_qwidget(FALSE), current_penpos(0,0) { -} - -TQPainter::TQPainter( const QWidget *pdev, bool unclipped) : QPainter((QWidget*)pdev), has_qwidget(TRUE), current_penpos(0,0) { - qwidget_ptr = (QWidget*)pdev; - if (unclipped) { - printf("[WARNING] Qt4 does not support drawing under child widgets in TQPainter via the unclipped==TRUE flag in any form!

TQPainter can draw everything from - simple lines to complex tqshapes like pies and chords. It can also - draw aligned text and pixmaps. Normally, it draws in a "natural" - coordinate system, but it can also do view and world - transformation. - - The typical use of a painter is: - - \list - \i Construct a painter. - \i Set a pen, a brush etc. - \i Draw. - \i Destroy the painter. - \endlist - - Mostly, all this is done inside a paint event. (In fact, 99% of - all TQPainter use is in a reimplementation of - TQWidget::paintEvent(), and the painter is heavily optimized for - such use.) Here's one very simple example: - - \code - void SimpleExampleWidget::paintEvent() - { - TQPainter paint( this ); - paint.setPen( TQt::blue ); - paint.drawText( rect(), AlignCenter, "The Text" ); - } - \endcode - - Usage is simple, and there are many settings you can use: - - \list - - \i font() is the currently set font. If you set a font that isn't - available, TQt tqfinds a close match. In fact font() returns what - you set using setFont() and fontInfo() returns the font actually - being used (which may be the same). - - \i brush() is the currently set brush; the color or pattern that's - used for filling e.g. circles. - - \i pen() is the currently set pen; the color or stipple that's - used for drawing lines or boundaries. - - \i backgroundMode() is \c Opaque or \c Transtqparent, i.e. whether - backgroundColor() is used or not. - - \i backgroundColor() only applies when backgroundMode() is Opaque - and pen() is a stipple. In that case, it describes the color of - the background pixels in the stipple. - - \i rasterOp() is how pixels drawn interact with the pixels already - there. - - \i brushOrigin() is the origin of the tiled brushes, normally the - origin of the window. - - \i viewport(), window(), tqworldMatrix() and many more make up the - painter's coordinate transformation system. See \link - coordsys.html The Coordinate System \endlink for an explanation of - this, or see below for a very brief overview of the functions. - - \i hasClipping() is whether the painter clips at all. (The paint - tqdevice clips, too.) If the painter clips, it clips to clipRegion(). - - \i pos() is the current position, set by moveTo() and used by - lineTo(). - - \endlist - - Note that some of these settings mirror settings in some paint - tqdevices, e.g. TQWidget::font(). TQPainter::begin() (or the TQPainter - constructor) copies these attributes from the paint tqdevice. - Calling, for example, TQWidget::setFont() doesn't take effect until - the next time a painter begins painting on it. - - save() saves all of these settings on an internal stack, restore() - pops them back. - - The core functionality of TQPainter is drawing, and there are - functions to draw most primitives: drawPoint(), drawPoints(), - drawLine(), drawRect(), drawWinFocusRect(), drawRoundRect(), - drawEllipse(), drawArc(), drawPie(), drawChord(), - drawLineSegments(), drawPolyline(), drawPolygon(), - drawConvexPolygon() and drawCubicBezier(). All of these functions - take integer coordinates; there are no floating-point versions - since we want drawing to be as fast as possible. - - There are functions to draw pixmaps/images, namely drawPixmap(), - drawImage() and drawTiledPixmap(). drawPixmap() and drawImage() - produce the same result, except that drawPixmap() is faster - on-screen and drawImage() faster and sometimes better on TQPrinter - and TQPicture. - - Text drawing is done using drawText(), and when you need - fine-grained positioning, boundingRect() tells you where a given - drawText() command would draw. - - There is a drawPicture() function that draws the contents of an - entire TQPicture using this painter. drawPicture() is the only - function that disregards all the painter's settings: the TQPicture - has its own settings. - - Normally, the TQPainter operates on the tqdevice's own coordinate - system (usually pixels), but TQPainter has good support for - coordinate transformation. See \link coordsys.html The Coordinate - System \endlink for a more general overview and a simple example. - - The most common functions used are scale(), rotate(), translate() - and shear(), all of which operate on the tqworldMatrix(). - setWorldMatrix() can tqreplace or add to the currently set - tqworldMatrix(). - - setViewport() sets the rectangle on which TQPainter operates. The - default is the entire tqdevice, which is usually fine, except on - printers. setWindow() sets the coordinate system, that is, the - rectangle that maps to viewport(). What's drawn inside the - window() ends up being inside the viewport(). The window's - default is the same as the viewport, and if you don't use the - transformations, they are optimized away, gaining another little - bit of speed. - - After all the coordinate transformation is done, TQPainter can clip - the drawing to an arbitrary rectangle or region. hasClipping() is - TRUE if TQPainter clips, and clipRegion() returns the clip region. - You can set it using either setClipRegion() or setClipRect(). - Note that the clipping can be slow. It's all system-dependent, - but as a rule of thumb, you can assume that drawing speed is - inversely proportional to the number of rectangles in the clip - region. - - After TQPainter's clipping, the paint tqdevice may also clip. For - example, most widgets clip away the pixels used by child widgets, - and most printers clip away an area near the edges of the paper. - This additional clipping is not reflected by the return value of - clipRegion() or hasClipping(). - - TQPainter also includes some less-used functions that are very - useful on those occasions when they're needed. - - isActive() indicates whether the painter is active. begin() (and - the most usual constructor) makes it active. end() (and the - destructor) deactivates it. If the painter is active, tqdevice() - returns the paint tqdevice on which the painter paints. - - Sometimes it is desirable to make someone else paint on an unusual - TQPaintDevice. TQPainter supports a static function to do this, - redirect(). We recommend not using it, but for some hacks it's - perfect. - - setTabStops() and setTabArray() can change where the tab stops - are, but these are very seldomly used. - - \warning Note that TQPainter does not attempt to work around - coordinate limitations in the underlying window system. Some - platforms may behave incorrectly with coordinates as small as - +/-4000. - - \headerfile tqdrawutil.h - - \sa TQPaintDevice TQWidget TQPixmap TQPrinter TQPicture - \link simple-application.html Application Walkthrough \endlink - \link coordsys.html Coordinate System Overview \endlink -*/ - -/*! - \fn TQGfx * TQPainter::internalGfx() - - \internal -*/ - -/*! - \enum TQPainter::CoordinateMode - \value CoordDevice - \value CoordPainter - - \sa clipRegion() -*/ -/*! - \enum TQPainter::TextDirection - \value Auto - \value RTL right to left - \value LTR left to right - - \sa drawText() -*/ - -/*! - \enum TQt::PaintUnit - \value PixelUnit - \value LoMetricUnit \e obsolete - \value HiMetricUnit \e obsolete - \value LoEnglishUnit \e obsolete - \value HiEnglishUnit \e obsolete - \value TwipsUnit \e obsolete -*/ - -/*! - \enum TQt::BrushStyle - - \value NoBrush - \value SolidPattern - \value Dense1Pattern - \value Dense2Pattern - \value Dense3Pattern - \value Dense4Pattern - \value Dense5Pattern - \value Dense6Pattern - \value Dense7Pattern - \value HorPattern - \value VerPattern - \value CrossPattern - \value BDiagPattern - \value FDiagPattern - \value DiagCrossPattern - \value CustomPattern - - \img brush-styles.png Brush Styles - -*/ - -/*! - \enum TQt::RasterOp - - This enum type is used to describe the way things are written to - the paint tqdevice.

The default pen style is \c - TQt::SolidLine. Setting the style to \c NoPen tells the painter to - not draw lines or outlines. - - When drawing 1 pixel wide diagonal lines you can either use a very - fast algorithm (specified by a line width of 0, which is the - default), or a slower but more accurate algorithm (specified by a - line width of 1). For horizontal and vertical lines a line width - of 0 is the same as a line width of 1. The cap and join style have - no effect on 0-width lines. - - The pen color defines the color of lines and text. The default - line color is black. The TQColor documentation lists predefined - colors. - - The cap style defines how the end points of lines are drawn. The - join style defines how the joins between two lines are drawn when - multiple connected lines are drawn (TQPainter::drawPolyline() - etc.). The cap and join styles only apply to wide lines, i.e. when - the width is 1 or greater. - - Use the TQBrush class to specify fill styles. - - Example: - \code - TQPainter painter; - TQPen pen( red, 2 ); // red solid line, 2 pixels wide - painter.begin( &anyPaintDevice ); // paint something - painter.setPen( pen ); // set the red, wide pen - painter.drawRect( 40,30, 200,100 ); // draw a rectangle - painter.setPen( blue ); // set blue pen, 0 pixel width - painter.drawLine( 40,30, 240,130 ); // draw a diagonal in rectangle - painter.end(); // painting done - \endcode - - See the \l TQt::PenStyle enum type for a complete list of pen - styles. - - With reference to the end points of lines, for wide (non-0-width) - pens it depends on the cap style whether the end point is drawn or - not. TQPainter will try to make sure that the end point is drawn - for 0-width pens, but this cannot be absolutely guaranteed because - the underlying drawing engine is free to use any (typically - accelerated) algorithm for drawing 0-width lines.
