Constructor & Destructor Documentation

KDChartCustomBox::KDChartCustomBox (  )  [inline]

Constructor.

Set default values.

Definition at line 65 of file KDChartCustomBox.h.

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.

Definition at line 106 of file KDChartCustomBox.h.

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  dataRow = 0,
uint  dataCol = 0,
uint  data3rd = 0,
uint  deltaAlign = KDCHART_AlignAuto,
bool  deltaScaleGlobal = true 
) [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.

uint  dataRow = 0,
uint  dataCol = 0,
uint  data3rd = 0,
uint  deltaAlign = KDCHART_AlignAuto,
bool  deltaScaleGlobal = true 
) [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.

In this case the content size is interpreted as rich text string - even if the text is NOT framed by <qt> and </qt>.
Parameters:
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.

void KDChartCustomBox::setInternalFlagAnchorBeingCalculated ( bool  flag  )  const [inline, protected]

Internal routine for recursion handling.

Note: This is a const methode changing NO VITAL information of the box but setting an internal, temporary flag.

void KDChartCustomBox::setPaper ( const QBrush &  paper  )  [inline, slot]

Specifies the brush to be used for the background.

Parameters:
paper The brush to be used for the background.

void KDChartCustomBox::setRotation ( int  rotation  )  [inline, slot]

Specifies the rotation angle of the box in degrees (0.

.360).

void KDChartCustomBox::setSize ( int  width,
int  height 
) [inline, slot]

Specifies the size of the box.

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:
width The width of the box. 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 logical height (or width, resp.) of the area to be used for drawing. Actual drawing position/size is calculated dynamically in methode trueRect.
height The height of the box.

QRect KDChartCustomBox::trueRect ( QPoint  anchor,
double  areaWidthP1000,
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.

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.
