详细描述

Base class for items on the plot canvas

A plot item is "something", that can be painted on the plot canvas, or only affects the scales of the plot widget. They can be categorized as:

Representator A "Representator" is an item that represents some sort of data on the plot canvas. The different representator classes are organized according to the characteristics of the data:
- QwtPlotMarker Represents a point or a horizontal/vertical coordinate
- QwtPlotCurve Represents a series of points
- QwtPlotSpectrogram ( QwtPlotRasterItem ) Represents raster data
- ...
Decorators A "Decorator" is an item, that displays additional information, that is not related to any data:
- QwtPlotGrid
- QwtPlotScaleItem
- QwtPlotSvgItem
- ...

Depending on the QwtPlotItem::ItemAttribute flags, an item is included into autoscaling or has an entry on the legend.

Before misusing the existing item classes it might be better to implement a new type of plot item ( don't implement a watermark as spectrogram ). Deriving a new type of QwtPlotItem primarily means to implement the YourPlotItem::draw() method.

参见: The cpuplot example shows the implementation of additional plot items.

成员枚举类型说明

◆ ItemAttribute

enum QwtPlotItem::ItemAttribute

Plot Item Attributes

Various aspects of a plot widget depend on the attributes of the attached plot items. If and how a single plot item participates in these updates depends on its attributes.

参见: setItemAttribute(), testItemAttribute(), ItemInterest

枚举值

Legend

The item is represented on the legend.

AutoScale

The boundingRect() of the item is included in the autoscaling calculation as long as its width or height is >= 0.0.

Margins

The item needs extra space to display something outside its bounding rectangle.

参见: getCanvasMarginHint()

◆ ItemInterest

enum QwtPlotItem::ItemInterest

Plot Item Interests

Plot items might depend on the situation of the corresponding plot widget. By enabling an interest the plot item will be notified, when the corresponding attribute of the plot widgets has changed.

参见: setItemAttribute(), testItemAttribute(), ItemInterest

枚举值

ScaleInterest

The item is interested in updates of the scales

参见: updateScaleDiv()

LegendInterest

The item is interested in updates of the legend ( of other items ) This flag is intended for items, that want to implement a legend for displaying entries of other plot item.

注解: If the plot item wants to be represented on a legend enable QwtPlotItem::Legend instead.

参见: updateLegend()

◆ RenderHint

enum QwtPlotItem::RenderHint

Render hints

枚举值
RenderAntialiased	Enable antialiasing

◆ RttiValues

enum QwtPlotItem::RttiValues

◆ boundingRect()

QRectF QwtPlotItem::boundingRect ( ) const

virtual

Get the bounding rectangle

返回: An invalid bounding rect: QRectF(1.0, 1.0, -2.0, -2.0)

注解: A width or height < 0.0 is ignored by the autoscaler.

被 QwtPlotArrowMarker, QwtPlotBarChart, QwtPlotBoxChart, QwtPlotGraphicItem, QwtPlotHistogram, QwtPlotIntervalCurve, QwtPlotMarker, QwtPlotMultiBarChart, QwtPlotRasterItem, QwtPlotSeriesItem, QwtPlotShapeItem, QwtPlotTradingCurve, QwtPlotVectorField , 以及 QwtPlotZoneItem 重载.

Create a default icon

Return a default icon from a brush

◆ detach()

void QwtPlotItem::detach ( )

This method detaches a QwtPlotItem from any QwtPlot it has been associated with. detach() is equivalent to calling attach( nullptr ).

参见: attach()

◆ draw()

参数

painter	Painter
xMap	Maps x-values into pixel coordinates.
yMap	Maps y-values into pixel coordinates.
canvasRect	Contents rect of the canvas in painter coordinates

在 QwtPlotTextLabel, QwtPlotZoneItem, QwtPlotMarker, QwtPlotGraphicItem, QwtPlotGrid, QwtPlotLegendItem, QwtPlotRasterItem, QwtPlotScaleItem, QwtPlotSeriesItem, QwtPlotShapeItem, QwtPlotSpectrogram , 以及 QwtPlotArrowMarker 内被实现.

When the QwtPlotItem::Margins flag is enabled the plot item indicates, that it needs some margins at the borders of the canvas. This is e.g. used by bar charts to reserve space for displaying the bars. The margins are in target device coordinates (pixels on screen). The default implementation returns 0 for all margins.

参见: QwtPlot::getCanvasMarginsHint(), QwtPlot::updateCanvasMargins()

被 QwtPlotAbstractBarChart 重载.

◆ hide()

void QwtPlotItem::hide ( )

Hide the item

Equivalent to calling setVisible( false ).

参见: show(), setVisible(), isVisible()

◆ isVisible()

Update the legend and call QwtPlot::autoRefresh() for the parent plot.

参见: QwtPlot::legendChanged(), QwtPlot::autoRefresh()

◆ legendChanged()

virtual

Return legend data

Return all information needed to represent the item on the legend

Most items are represented by one entry on the legend showing an icon and a text, but e.g. QwtPlotMultiBarChart displays one entry for each bar. QwtLegendData is basically a list of QVariants that makes it possible to overload and reimplement legendData() to return almost any type of information, that is understood by the receiver that acts as the legend. The default implementation returns one entry with the title() of the item and the legendIcon().

参见: title(), legendIcon(), QwtLegend, QwtPlotLegendItem

Get the plot the item is attached to

返回: Attached plot, or nullptr if not attached

◆ renderThreadCount()

uint QwtPlotItem::renderThreadCount ( ) const

◆ rtti()

int QwtPlotItem::rtti ( ) const

virtual

Runtime type information

Get runtime type information

返回: rtti value for the specific class

Return rtti for the specific class represented. QwtPlotItem is simply a virtual interface class, and base classes will implement this method with specific rtti values so a user can differentiate them.
