Detailed Description

Graphic class that displays a time scale.

Library: views

The IlvTimeScale class is a time scale component that contains several IlvTimeScaleRow objects. Each row represents a particular time unit and is responsible for drawing itself. The rows are not true UI components, but behave like renderers.

To scroll through the scale or to zoom on it when changing the time value and the visible duration, a new IlvTimeConverter object must be set for the scale.

setTimeConverter()

Constructor & Destructor Documentation

◆ IlvTimeScale()

IlvTimeScale::IlvTimeScale ( IlvDisplay display,
const IlvRect drawrect,
IlvPalette palette = 0 
)

Constructor.

Creates a new IlvTimeScale that initially contains no rows. By default, the time scale uses an IlvLinearTimeConverter. The time scale's time converter can be set by calling the setTimeConverter() method.

Parameters
displayThe display this graphic will use.
drawrectThe rectangle the scale will be drawn into.
paletteThe palette to use, or 0 to use the default palette.

Member Function Documentation

◆ addRow()

virtual void IlvTimeScale::addRow ( IlvTimeScaleRow row)
virtual

Append the specified IlvTimeScaleRow to the scale.

To see the modification, you must redraw the object.

Parameters
rowThe row to be added.
See also
removeRow()

◆ applyTransform()

void IlvTimeScale::applyTransform ( const IlvTransformer t)
virtual

Applies a transformation function to the graphic object.

Applies the transformer t to the shape of the object. Unless the transformation is a scaling operation, the result of applying it to certain objects can be insignificant. For example, applying a non-scaling transformer to an IlvRectangle object is meaningless, since the rectangle remains a rectangle. On the other hand, meaningful transformations can be applied to objects that are instances of types such as IlvLine or IlvPolyPoints.

Note
applyTransform() is one of the most important method to be rewritten for classes derived from IlvGraphic, since it is called by the resize(), move(), moveResize(), scale(), etc., methods.
Parameters
tThe transformer value. If 0, no transformation is performed.

Implements IlvGraphic.

◆ boundingBox()

virtual void IlvTimeScale::boundingBox ( IlvRect bbox,
const IlvTransformer t = 0 
) const
virtual

Retrieves the bounding box of the graphic object.

Sets bbox, the rectangle reference parameter, to be the bounding box of the object. Since the object can appear within a transformed environment (for example, in a multiview editor), an IlvTransformer object occurs as an optional parameter in order to compute the bounding box in the coordinate system of the transformed environment.

Parameters
bboxThe bounding box to be set.
tA transformer value or 0 if there is no transformation.

Implements IlvGraphic.

◆ createPaintContext()

IlvTimeScalePaintContext* IlvTimeScale::createPaintContext ( IlDate  start,
IlvDuration  duration,
IlvRect  viewport 
)

Create a IlvTimeScalePaintContext.

Creates a IlvTimeScalePaintContext so that the time scale paints the specified time interval into the specified view port. Caller owns the returned object.

Parameters
startThe begin of the visible time interval.
durationThe duration of the visible time interval.
viewportThe rectangle defining the position the time scale to paint to.
Returns
The paint context.

◆ draw()

void IlvTimeScale::draw ( IlvPort dst,
const IlvTransformer t = 0,
const IlvRegion clip = 0 
) const
virtual

Draws the graphic object.

Draws the object in the given IlvPort using the transformer t.

Parameters
dstThe destination port this object is drawn onto.
tThe transformer value. If 0, no transformation is performed.
clipThe clipping region, relative to the transformed object, or 0 if none.

Implements IlvGraphic.

◆ getCalendar()

IlCalendar* IlvTimeScale::getCalendar ( IlDate  time)

Get the internal calendar set to the specified time.

Parameters
timeThe time to set the calendar to.

◆ getLocation() [1/2]

virtual IlInt IlvTimeScale::getLocation ( IlDate  time)
virtual

Get the x position corresponding to the specified time.

Parameters
timeThe time.
Returns
the coordinate corresponding to the IlDate.

◆ getLocation() [2/2]

virtual IlInt IlvTimeScale::getLocation ( IlDate  time,
const IlvTimeScalePaintContext context 
)
virtual

Get the x position corresponding to the specified time in the specified paint context.

Parameters
timeThe time.
contextThe paint context.
Returns
The x position.

◆ getMaxVisibleTime()

virtual IlDate IlvTimeScale::getMaxVisibleTime ( ) const
virtual

Returns the maximum time that the time scrollable can show.

Returns
The maximum visible time.
See also
setMaxVisibleTime()

Implements IlvTimeScrollable.

◆ getMinVisibleTime()

virtual IlDate IlvTimeScale::getMinVisibleTime ( ) const
virtual

Returns the minimum time that the time scrollable can show.

Returns
The minimum visible time.
See also
setMinVisibleTime()

Implements IlvTimeScrollable.

◆ getPaintContext()

IlvTimeScalePaintContext* IlvTimeScale::getPaintContext ( )

Gets the scales' cached IlvTimeScalePaintContext.

Gets the cached IlvTimeScalePaintContext used to paint the time scale on screen.

Caller owns the returned object

Returns
The cached paint context.

◆ move()

virtual void IlvTimeScale::move ( IlvPos  x,
IlvPos  y 
)
virtual

Moves the graphic object.

Moves the upper left corner of the bounding box of the object to the position (x, y). The default implementation calls the member function translate().

Parameters
xThe x coordinate position.
yThe y coordinate position.

Reimplemented from IlvGraphic.

◆ removeRow()

virtual IlBoolean IlvTimeScale::removeRow ( IlvTimeScaleRow row)
virtual

Remove a row from the IlvTimeScale object.

To see the modification, you must redraw the object.

Parameters
rowThe row to be removed.
Returns
IlTrue if the specified row was found in the object, IlFalse otherwise.

◆ setLabelVisible()

void IlvTimeScale::setLabelVisible ( IlBoolean  visible)

Specifies whether the labels should be visible.

Parameters
visibleIlTrue if the labels should be visible or IlFalse if they should not.

◆ setMaxVisibleTime()

virtual void IlvTimeScale::setMaxVisibleTime ( IlDate  d)
virtual

Sets the maximum time that the time scrollable can show.

The current visible time and duration are trimmed to fit the new min-max interval by calling the IlvTimeScrollUtil::trimInterval() method.

Parameters
dThe maximum visible time.

getMaxVisibleTime()
getVisibleDuration()

Implements IlvTimeScrollable.

◆ setMinVisibleTime()

virtual void IlvTimeScale::setMinVisibleTime ( IlDate  d)
virtual

Sets the minimum time that the time scrollable can show.

The current visible time and duration are trimmed to fit the new min-max interval by calling the IlvTimeScrollUtil::trimInterval() method.

Parameters
dThe minimum visible time.

◆ setRow()

virtual void IlvTimeScale::setRow ( IlInt  index,
IlvTimeScaleRow row 
)
virtual

Change the IlvTimeScaleRow object at a specified index.

Parameters
indexThe index of the changed row. The index value must be valid (not greater than the actual number of rows).
rowThe new IlvTimeScaleRow.

Reimplemented in IlvCalendarScale.

◆ setSeparatorVisible()

void IlvTimeScale::setSeparatorVisible ( IlBoolean  visible)

Specifies whether the separators should be visible.

Parameters
visibleIlTrue if the separators should be visible or IlFalse if they shoud not.

◆ setTimeConverter()

void IlvTimeScale::setTimeConverter ( IlvTimeConverter t)

Sets the convertor of the time scale.

This method can be used to change the IlvTimeConverter object of this scale.

This object allows you to draw the scale correctly by converting time value to units on the screen.

Note
The scale takes ownership of the time converter, it will be deleted along with the scale or when a new time converter is set.
Parameters
tThe new IlvTimeConverter object.

◆ setVisibleDuration()

virtual void IlvTimeScale::setVisibleDuration ( IlvDuration  duration)
virtual

Sets the duration of the time interval displayed by the time scrollable.

The specified duration is compared against the min and max visible times and is trimmed if necessary by calling the IlvTimeScrollUtil::trimInterval() method. If you are changing both the visible time and duration, it is preferable to use the setVisibleInterval() method instead.

Parameters
durationThe new duration value.
