Detailed Description

The Meter is a classic gauge widget supporting alarms, ticks, decimal numbers and lots of properties for styling/customizing the widget.

The meter is based on svg, but most visual features can be overridden by properties.

Styling by SVG

Use the svgFile property to style the widget using a svg file. Styling by svg enables switching between different themes in runtime (as long as the files are placed at identical locations within theme directories).

Main element structure

The following tree view shows the svg structure that can be used on the CDPBaseMeter.

The following table explains the named elements in more detail.

PropertyTypeDescription
cdpToprect or an element group containing a rectThe cdpTop element should contain graphics like glass or similar to be painted on top of other graphics in the svg. To ensure that the svg parser gets the correct size (and aspect ratio), we have to place a transparent rect along with the graphics within a group element.
cdpNeedleCenterCWrectThe center of this rectangle should be placed at the rotation point of the cdpNeedle graphics Note that to get counter clock wise rotation (from min to max) the name of this element must be changed to cdpNeedleCenterCCW.
cdpNeedleMinrectThe center of this rect should be placed at the minimum position that the needle can move to (tip of the needle will ne placed at the center of the point).
cdpNeedleMaxrectThe center of this rect should be placed at the maximum position that the needle can move to (tip of the needle will ne placed at the center of the point).
cdpNeedleGraphicsgroup containing rects for outline and needle center in a group containing the actual graphicsThe transparent rect describing the needle size must be named cdpRectOutline while the needle center must be named cdpRectCenter. The group containing the actual graphics doesn't require a name. Draw the needle pointing upwards.
cdpTextValuegroup containing rect and textThe value of the meter will get placed within this rect and get color and size similar to the the text element. Styles added in layer, Styles, are only supported in meters with one needle.
cdpTextPrefixgroup containing rect and textThe prefix or main text of the meter will get placed within this rect and get color and size similar to the the text element.
cdpTextSuffixgroup containing rect and textThe suffix text of the meter will get placed within this rect and get color and size similar to the the text element.
cdpTicksNumbertextThis text enables tick numbers and sets font color and size (font family is read from the interface). Note that though this element is not present, tick numbers can be enabled using the numShow widget property.
cdpTicksColortextThis text enables ticks and sets the tick color. Note that though this element is not present, ticks can be enabled using the 'ticksShow' widget property.
cdpTicksMinorNo3TrectThe number between 'No' and 'T' is the default number of minor ticks (between major ticks).
cdpTicksMajorNo9TrectThe number between 'No' and 'T' is the default number of minor ticks (between major ticks).
cdpTicksOffsetrectOffset between the needle point and the tick. Add the word "Negative" to the name for negative direction.
cdpTicksNumOffsetrectOffset between tick and number. Add the word "Negative" to the name for negative direction.
cdpTicksNumRectrectThe max width of the tick numbers. When the limit is reached, numbers will get scaled down to fit this width. The element is optional, but when not present, a large maxValue might make the meter look weird if the background is not designed for it.
cdpTicksMajorSizerectThe rect specifies the width and height of the major ticks.
cdpTicksMinorSizerectThe rect specifies the width and height of the minor ticks.
cdpFillColortextThis text enables fill sector and sets the fill color. Note that though this element is not present, fill sector can be enabled using the CDPBaseMeter::fill widget property. The user will then have to specify the color manually in CDPBaseMeter::fillColor.
cdpFillOffsetrectThe height of this rect specifies the offset from needle tip to the edge of the fill sector. When fillOffset is not set, CDPBaseMeter::ticksOffset will be used instead.
cdpFillWidthrectThe height of this rect specifies the thickness/width of the fill sector. When fill width is not set, CDPBaseMeter::ticksMinorLength will be used instead.
cdpBackgroundrect or an element group containing a rectThe cdpBackground should contain the actual background graphics. To ensure that the svg parser gets the correct background size (and aspect ratio), we have to place a transparent rect along with the graphics within a group element.

Style element structure

The meter supports the following structure for styles.

            ├─── < Path >       (transparent rect/path)
            └─── < Group >      (graphics)

Note: The art boards of the document must be identical to the bacground rect unless wanting to offset contents like ticks, numbers and needle. In Adobe Illustrator, the artboards are edited in document setup.

Member Type Documentation

enum CDPBaseMeter::AspectRatio

This enum type specifies how to handle aspect ratio:

ConstantValueDescription
CDPBaseMeter::Unlocked0Sets no aspect ratio. This can make the widget look undesirable, because the “ticks” uses the coordinates of the svg.
CDPBaseMeter::Locked1Sets aspect ratio as specified by the original sized svg.
CDPBaseMeter::HeightForWidth2Sets the default height identical to the width, but in most cases this option will be identical to “Locked”.

typedef CDPBaseMeter::MeterDataMap

typedef CDPBaseMeter::MeterSvgMap

enum CDPBaseMeter::MeterType

This enum type specifies a styling type:

ConstantValueDescription
CDPBaseMeter::Custom0Style by svg file (enables svgFile property).
CDPBaseMeter::Round1Generates stylesheet with color.

cdpScaling : const double

This property holds the factor to multiply the incoming signal/property value.

cdpStyleRouting : QString

Set the routing of the CDP object that are to change the widget svg style. Note that when cdpStyleProperty is empty we assume the object to be a CDPSignal (similar to adding 'Value' in cdpStyleProperty).

Access functions:

QString cdpStyle()
void setCdpStyle(QString routing)

fill : bool

This property holds whether to enable or disable the fill sector.

When the property is not edited, meaning that the property name does not show in bold text in the property pane, the fill sector is enabled automatically based on the SVG file that styles the widget. In other words, it shows whether the SVG is configured to show fill by default.

Setting this property to false, ensures that fill is disabled even though it might be supported by the SVG. This could increase performance on systems with limited resources (as the widget won't need to repaint the fill sector each paint event).

The only reason to set the property true, is in a scenario where the fill should always show. This is useful if you want to set fill sector on a SVG that does not support it by default, and maintain the fill sector when switching between two such themes. Note that having it true while switching between non fill and default fill themes will make the fill color of the latter show for both themes.

Access functions:

virtual bool fillEnabled(int layer = FirstLayer)
virtual void setFillEnabled(bool enable, int layer = FirstLayer)

See also fillOffset, fillWidth, and fillColor.

fillColor : QColor

This property holds the color to fill the sector from min to current value.

Setting the property to any color will enable fill, while pressing the reset button next to the property will disable it.

Note that switching theme will override any manual color configuration. To make a fill color stick when switching theme, this have to be added to the SVG file as described in the meter styling guide.

Access functions:

virtual QColor fillColor(int layer = FirstLayer)
virtual void setFillColor(const QColor &color, int layer = FirstLayer)

See also fillOffset and fillWidth.

fillOffset : double

This property holds the offset from needle tip to the edge of the fill sector.

When fillOffset is not set, CDPBaseMeter::ticksOffset will be used instead.

Set CDPBaseMeter::svgUpdateAll to false to make properties like offset stick when switching themes. When false, only properties that affect colors will get updated from the SVG.

Access functions:

virtual double fillOffset(int layer = FirstLayer)
virtual void setFillOffset(double offset, int layer = FirstLayer)

See also fillColor and fillWidth.
