Detailed Description

Class for specifying and drawing custom boxes.

Constructor & Destructor Documentation

KDChartCustomBox::KDChartCustomBox ( ) [inline]

Constructor. Set default values.

KDChartCustomBox::KDChartCustomBox ( const KDChartTextPiece & content,

int fontSize,

bool fontScaleGlobal = true

) [inline]

Constructor. Set content and font size but no position/size parameters.

Note:
If fontScaleGlobal is set to true it is not necessary to specify the size of the box: if both width and height are zero and fontScaleGlobal is true the size of the box will be calculated automatically based upon the content size. In this case the content size is interpreted as rich text string - even if the text is NOT framed by <qt> and </qt>.

Parameters:

content The string or rich text string to be written into the box.

fontSize The size of the font to be used, see explanation above.

fontScaleGlobal If true the font size will be calculated based upon the the size of the drawing area, otherwise it will be calculated based upon the height of the box.

KDChartCustomBox::KDChartCustomBox ( const KDChartTextPiece & content,

int fontSize,

bool fontScaleGlobal,

int deltaX,

int deltaY,

int width,

int height,

const QColor & color = QColor( Qt::black ),

const QBrush & paper = QBrush( Qt::NoBrush ),

uint area = KDChartEnums::AreaInnermost,

KDChartEnums::PositionFlag position = KDChartEnums::PosTopLeft,

uint align = Qt::AlignTop + Qt::AlignLeft,

uint dataRow = 0,

uint dataCol = 0,

uint data3rd = 0,

uint deltaAlign = KDCHART_AlignAuto,

bool deltaScaleGlobal = true,

int parentAxis = -1

) [inline]

Constructor. Set content and position/size parameters and the color and brush to be used.

Note:
If fontScaleGlobal is set to true it is not necessary to specify the size of the box: if both width and height are zero and fontScaleGlobal is true the size of the box will be calculated automatically based upon the content size. In this case the content size is interpreted as rich text string - even if the text is NOT framed by <qt> and </qt>.

Parameters:

content The text piece to be displayed.

fontSize If fontSize value is greater 0, the value is taken as exact size, if fontSize is less than 0 it is interpreted as being a per-mille value of the size of the drawing area (or of the height of the box in case fontScaleGlobal is set to false, resp.). Normally the actual font size is calculated dynamically in methode paint. However if fontSize is zero no calculating will take place but the size of the content font is used.

fontScaleGlobal If true the font size will be calculated based upon the the size of the drawing area, otherwise it will be calculated based upon the height of the box.

deltaX The X distance between the box and its anchor. Note: If greater 0, the value is taken as exact offset, if less than 0, it is interpreted as being a per-mille value of the size of the drawing area (or as percent value of the actual font size (as returned by QFontMetrics::lineSpacing() ) if deltaScaleGlobal is FALSE, resp.). Actual drawing position/size is calculated dynamically in methode trueRect.

deltaY The Y distance between the box and its anchor.

width The width of the box.

height The height of the box.

color The text color.

paper The brush to be used for the background.

area The area to which the box is to be aligned.

position The anchor position. This is the edge (or the corner, resp.) of the area to which the box is to be aligned.

align The way how the box is to be aligned to its anchor.

dataRow The row number of the KDChart data region that is to be used as anchor area. This parameter is ignored if area is not AreaChartDataRegion.

dataCol The column number of the KDChart data region that is to be used as anchor area. This parameter is ignored if area is not AreaChartDataRegion.

data3rd The third dimensions number of the KDChart data region that is to be used as anchor area. This parameter is ignored if area is not AreaChartDataRegion or if there is no 3-dimensional data structure.

deltaAlign The way how deltaX and affect the position of the box. Leave this parameter to its default value KDCHART_AlignAuto to have the delta values used according to the box's main align settings, otherwise specify your own alignment settings: e.g. right means there will be a gap between the right side of the box and its anchor point - if the main align parameter is set to right too the anchor point will to be outside of the box / if align is set to left (but the deltaAlign to right) the anchor point will be inside the box. Possible values for deltaAlign are:

KDCHART_AlignAuto

Qt::AlignLeft | Qt::AlignTop

Qt::AlignLeft | Qt::AlignBottom

Qt::AlignRight | Qt::AlignTop

Qt::AlignRight | Qt::AlignBottom Using AlignVCenter or AlignHCenter or AlignCenter does not make sense here: center delta alignment will cause KDChart to ignore the respective delta settings: deltaX or deltaY or both will become ineffective.

deltaScaleGlobal If true the actual delta X and delta Y values will be calculated by deltaX and deltaY based upon the size of the drawing area, otherwise they will be calculated based upon the actual font size.

KDChartCustomBox::KDChartCustomBox ( int rotation,

const KDChartTextPiece & content,

int fontSize,

bool fontScaleGlobal,

int deltaX,

int deltaY,

int width,

int height,

const QColor & color = QColor( Qt::black ),

const QBrush & paper = QBrush( Qt::NoBrush ),

uint area = KDChartEnums::AreaInnermost,

KDChartEnums::PositionFlag position = KDChartEnums::PosTopLeft,

uint align = Qt::AlignTop + Qt::AlignLeft,

uint dataRow = 0,

uint dataCol = 0,

uint data3rd = 0,

uint deltaAlign = KDCHART_AlignAuto,

bool deltaScaleGlobal = true,

int parentAxis = -1

) [inline]

Constructor. Use this special constructor to specify a rotated box, reference point of the rotation is the anchor specified by the area and the position parameters.

Note:
If fontScaleGlobal is set to true it is not necessary to specify the size of the box: if both width and height are zero and fontScaleGlobal is true the size of the box will be calculated automatically based upon the content size. In this case the content size is interpreted as rich text string - even if the text is NOT framed by <qt> and </qt>.

Parameters:

rotation The box's rotation angle in degrees (0 .. 360).

content The text piece to be displayed.

fontSize If fontSize value is greater 0, the value is taken as exact size, if fontSize is less than 0 it is interpreted as being a per-mille value of the size of the drawing area (or of the height of the box in case fontScaleGlobal is set to false, resp.). Normally the actual font size is calculated dynamically in methode paint. However if fontSize is zero no calculating will take place but the size of the content font is used.

fontScaleGlobal If true the font size will be calculated based upon the the size of the drawing area, otherwise it will be calculated based upon the height of the box.

deltaX The X distance between the box and its anchor. Note: If greater 0, the value is taken as exact offset, if less than 0, it is interpreted as being a per-mille value of the width of the drawing area (or as percent value of the actual font size (as returned by QFontMetrics::lineSpacing() ) if deltaScaleGlobal is FALSE, resp.). Actual drawing position/size is calculated dynamically in method trueRect.

deltaY The Y distance between the box and its anchor. Note: If greater 0, the value is taken as exact offset, if less than 0, it is interpreted as being a per-mille value of the height of the drawing area (or as percent value of the actual font size (as returned by QFontMetrics::lineSpacing() ) if deltaScaleGlobal is FALSE, resp.). Actual drawing position/size is calculated dynamically in method trueRect.

width The width of the box.

height The height of the box.

color The text color.

paper The brush to be used for the background.

area The area to which the box is to be aligned.

position The anchor position. This is the edge (or the corner, resp.) of the area to which the box is to be aligned and it is also used as the reference point of the rotation.

align The way how the box is to be aligned to its anchor.

dataRow The row number of the KDChart data region that is to be used as anchor area. This parameter is ignored if area is not AreaChartDataRegion.

dataCol The column number of the KDChart data region that is to be used as anchor area. This parameter is ignored if area is not AreaChartDataRegion.

data3rd The third dimensions number of the KDChart data region that is to be used as anchor area. This parameter is ignored if area is not AreaChartDataRegion or if there is no 3-dimensional data structure.

deltaAlign The way how deltaX and affect the position of the box. Leave this parameter to its default value KDCHART_AlignAuto to have the delta values used according to the box's main align settings, otherwise specify your own alignment settings: e.g. Qt::AlignRight means the box will be moved to the left (by the amount calculated using the deltaX value), so there will be a gap between the right side of the box and its anchor point IF the main align flag is set to Qt::AlignRight too, so the anchor point will to be outside of the box then. However if the main align flag is set to Qt::AlignLeft the anchor point will be inside the box. Possible values for deltaAlign are:

KDCHART_AlignAuto

Qt::AlignLeft | Qt::AlignTop

Qt::AlignLeft | Qt::AlignBottom

Qt::AlignRight | Qt::AlignTop

Qt::AlignRight | Qt::AlignBottom Using AlignVCenter or AlignHCenter or AlignCenter does not make sense here: center delta alignment will cause KDChart to ignore the respective delta settings: deltaX or deltaY or both will become ineffective.

Note:
Moving of the box due to deltaAlign settings is applied after the box is rotated: e.g. this means a gap specified by deltaAlign = Qt::AlignTop gap will actually result in a left gap if the box is rotated by 90 degrees.

Parameters:

deltaScaleGlobal If true the actual delta X and delta Y values will be calculated by deltaX and deltaY based upon the size of the drawing area, otherwise they will be calculated based upon the actual font size.

Specifies the way how the values specified for deltaX and/or deltaY affect the position of the box.
Set this to KDHART_KDCHART_AlignAuto to have the delta values used according to the box's main align settings, otherwise specify your own alignment settings: e.g. right means there will be a gap between the right side of the box and its anchor point - if the main align parameter is set to right too the anchor point will to be outside of the box / if align is set to left (but the deltaAlign to right) the anchor point will be inside the box. Possible values for deltaAlign are:

KDCHART_AlignAuto

Qt::AlignLeft | Qt::AlignTop

Qt::AlignLeft | Qt::AlignBottom

Qt::AlignRight | Qt::AlignTop

Qt::AlignRight | Qt::AlignBottom Using AlignVCenter or AlignHCenter or AlignCenter does not make sense here: center delta alignment will cause KDChart to ignore the respective delta settings: deltaX or deltaY or both will become ineffective.
Note:
Moving of the box due to deltaAlign settings is applied after the box is rotated: e.g. this means a gap specified by deltaAlign = Qt::AlignTop gap will actually result in a left gap if the box is rotated by 90 degrees.

Parameters:

deltaScaleGlobal If true the actual delta X and delta Y values will be calculated by deltaX and deltaY based upon the size of the drawing area, otherwise they will be calculated based upon the actual font size.

Note:
If fontScaleGlobal is set to true it is not necessary to specify the size of the box: if both width and height are zero and fontScaleGlobal is true the size of the box will be calculated automatically based upon the content size. In this case the content size is interpreted as rich text string - even if the text is NOT framed by <qt> and </qt>.

Parameters:

deltaX The X distance between the box and its anchor. Note: If greater 0, the value is taken as exact offset, if less than 0, it is interpreted as being a per-mille value of the size of the drawing area (or as percent value of the actual font size (as returned by QFontMetrics::lineSpacing() ) if deltaScaleGlobal is FALSE, resp.). Actual drawing position/size is calculated dynamically in methode trueRect.

deltaY The Y distance between the box and its anchor.

align the way how the values specified for deltaX and/or deltaY affect the position of the box.

deltaScaleGlobal If true the actual delta X and delta Y values will be calculated by deltaX and deltaY based upon the size of the drawing area, otherwise they will be calculated based upon the actual font size.

void KDChartCustomBox::setFontSize ( int fontSize,

bool fontScaleGlobal

) [inline, slot]

Specifies the font size to be used.

Note:
If fontScaleGlobal is set to true it is not necessary to specify the size of the box: if both width and height are zero and fontScaleGlobal is true the size of the box will be calculated automatically based upon the content size. In this case the content size is interpreted as rich text string - even if the text is NOT framed by <qt> and </qt>.

double areaHeightP1000

) const [virtual, slot]

Return the actual rectangle which to draw box into.

Parameters:

anchor The anchor point which the box is to be aligned to. This can be any point within the painter drawing area but you will probably compute a point using anchorArea(), anchorPosition(), anchorAlign() (and dataRow(), dataCol(), data3rd() when dealing with KDChart data regions, resp.)

areaWidthP1000 The thousands part of the logical width of the area to be used for drawing.

areaHeightP1000 The thousands part of the logical height of the area to be used for drawing.

QRect KDChartCustomBox::trueRect ( QPainter * painter,

QPoint anchor,

double areaWidthP1000,

double areaHeightP1000

) const [slot]

Return the actual rectangle which to draw box into.

Note:
When ever possible, use this method, instead of the other trueRect(), that has no QPainter parameter. Passing a QPainter will give you more exact results.

Parameters:

painter The QPainter to be used.

anchor The anchor point which the box is to be aligned to. This can be any point within the painter drawing area but you will probably compute a point using anchorArea(), anchorPosition(), anchorAlign() (and dataRow(), dataCol(), data3rd() when dealing with KDChart data regions, resp.)

areaWidthP1000 The thousands part of the logical width of the area to be used for drawing.

areaHeightP1000 The thousands part of the logical height of the area to be used for drawing.

int KDChartCustomBox::trueRectAlignX ( const QRect & rect ) const [slot]

int KDChartCustomBox::trueRectAlignY ( const QRect & rect ) const [slot]

int KDChartCustomBox::width ( ) const [inline, slot]

Returns the width of the region where to draw the box. Note: If greater 0, the value is the exact offset, if less than 0, it is interpreted as being a per-mille value of the logical height (or width, resp.) of the area to be used for drawing. Actual drawing position/size is calculated dynamically in methode trueRect.
