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.

See also: setTimeConverter()

Constructor & Destructor Documentation

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

display	The display this graphic will use.
drawrect	The rectangle the scale will be drawn into.
palette	The palette to use, or 0 to use the default palette.

Member Function Documentation

virtual void IlvTimeScale::addRow ( IlvTimeScaleRow * row )

virtual

Append the specified IlvTimeScaleRow to the scale.

To see the modification, you must redraw the object.

Parameters

row	The row to be added.

See also: removeRow()

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

t	The transformer value. If `0`, no transformation is performed.

Implements IlvGraphic.

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

bbox	The bounding box to be set.
t	A transformer value or `0` if there is no transformation.

Implements IlvGraphic.

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

start	The begin of the visible time interval.
duration	The duration of the visible time interval.
viewport	The rectangle defining the position the time scale to paint to.

Returns: The paint context.

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

dst	The destination port this object is drawn onto.
t	The transformer value. If `0`, no transformation is performed.
clip	The clipping region, relative to the transformed object, or `0` if none.

Implements IlvGraphic.

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.

virtual IlvTimeScaleRow* IlvTimeScale::getRow ( IlInt index ) const

virtual

Get the IlvTimeScaleRow at a specified index.

Parameters

index The index of the returned row. The index value must be valid (not greater than the actual number of rows).

Returns: the IlvTimeScaleRow.

virtual IlDate IlvTimeScale::getTime ( IlInt x )

virtual

Get the time that is under the x position in the component.

Returns the beginning of the time interval displayed by the time scrollable.

See also: setVisibleTime()

Implements IlvTimeScrollable.

virtual void IlvTimeScale::hideRow ( IlvTimeScaleRow * row )

virtual

Hide the specified row.

Parameters

row	The row to be hidden.

virtual void IlvTimeScale::hideRow ( IlInt index )

virtual

Hide the specified row.

Parameters

index The index of the row to be hidden.

IlBoolean IlvTimeScale::isLabelVisible ( ) const

Returns whether the labels should be visible.

Returns: Whether the labels should be visible.

IlBoolean IlvTimeScale::isSeparatorVisible ( ) const

Returns whether the separators should be visible.

Returns: IlTrue if the separators should be visible, otherwise IlFalse.

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

x	The `x` coordinate position.
y	The `y` coordinate position.

Reimplemented from IlvGraphic.

virtual IlBoolean IlvTimeScale::removeRow ( IlvTimeScaleRow * row )

virtual

Remove a row from the IlvTimeScale object.

To see the modification, you must redraw the object.

Parameters

row	The row to be removed.

Returns: IlTrue if the specified row was found in the object, IlFalse otherwise.

void IlvTimeScale::setLabelVisible ( IlBoolean visible )

Specifies whether the labels should be visible.

Parameters

visible IlTrue if the labels should be visible or IlFalse if they should not.

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

d	The maximum visible time.

See also: getMaxVisibleTime(); getVisibleDuration()

Implements IlvTimeScrollable.

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

d	The minimum visible time.

See also: getMinVisibleTime(); getVisibleDuration()

Implements IlvTimeScrollable.

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

virtual

Change the IlvTimeScaleRow object at a specified index.

Parameters

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

Reimplemented in IlvCalendarScale.

void IlvTimeScale::setSeparatorVisible ( IlBoolean visible )

Specifies whether the separators should be visible.

Parameters

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

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

t	The new `IlvTimeConverter` object.

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

duration The new duration value.

See also: getVisibleDuration(); getMinVisibleTime(); getMaxVisibleTime()

Implements IlvTimeScrollable.

Reimplemented in IlvCalendarScale.

virtual void IlvTimeScale::setVisibleInterval	(	IlDate	time,
		IlvDuration	duration
	)

virtual

Sets the time interval displayed by the scale.

The specified duration is compared against the min and max visible times and is trimmed if necessary by calling the IlvTimeScrollUtil::trimInterval() method.

Parameters

time	The new time value.
duration	The new duration value.
