Destructor.

The destructor deletes all the graphic objects managed by the container.

Member Function Documentation

void IlvContainer::abortReDraw ( )

Aborts a redraw.

Forgets all invalidated areas. If calls to initReDraw() were embedded, they are all reset.

void IlvContainer::addAccelerator ( IlvContainerAccelerator * accelerator )

Adds or replaces a specified accelerator.

Installs an accelerator as a new accelerator in this container. If there already was a matching accelerator (same type, data (button or key), and modifiers), then the previous accelerator is removed (but not destroyed).

Parameters

accelerator The accelerator.

void IlvContainer::addAccelerator	(	IlvContainerAction	action,
		IlvEventType	type,
		IlUShort	data = `0`,
		IlUShort	modifiers = `0`,
		IlAny	userArg = `0`,
		IlUShort	optModifiers = `0`
	)

Adds an accelerator to the container.

Creates an IlvContainerAccelerator using the same arguments and adds it to the IlvContainer accelerator list (see the constructor for argument descriptions). When the container receives an event, it checks its accelerator list. If an appropriate accelerator is found, that is, accelerator->trigger(<event description>) returns IlTrue, then accelerator->activate is called.

Parameters

action	The user function used as the accelerator action.
type	The accelerator event type.
data	The accelerator event data (button or key).
modifiers	The accelerator event modifiers.
userArg	The accelerator action user argument.
optModifiers	The accelerator optional event modifiers.

virtual void IlvContainer::addObject	(	IlvGraphic *	obj,
		IlBoolean	redraw = `IlFalse`
	)

virtual

Adds an object at the top of the container list.

The object is appended at the final position. In other words, the new object is placed "on top of" all the others.

Note: If the object has a name that is already in use in this container, the name is removed from the object.

Parameters

obj	The object to be added.
redraw	If set to `IlTrue` the container display is updated.

virtual void IlvContainer::addObject	(	const char *	objectName,
		IlvGraphic *	obj,
		IlBoolean	redraw = `IlFalse`
	)

virtual

Adds an object to the top of the container list and names the object.

Calls addObject(obj, redraw) then setObjectName(name).

Note: If the object has a name that is already in use in this container, the name is removed from the object.

Parameters

objectName	The name of the object.
obj	The object to be added.
redraw	If set to `IlTrue` the container is redrawn. If it is set to `IlFalse`, the container will not be redrawn.

virtual IlBoolean IlvContainer::addSmartSet	(	IlvSmartSet *	set,
		IlBoolean	redraw = `IlTrue`
	)

virtual

Adds a SmartSet.

The set to be added must have a name. If there already is a SmartSet in this container with the same name, the SmartSet is renamed by adding 1 at the end of the name, or by incrementing the decimal value at the end of the name.

If the SmartSet contains objects that are not stored in this container, they are added to the container.

Parameters

set	The SmartSet to be added.
redraw	If set to `IlTrue` the container is redrawn. If it is set to `IlFalse`, the container will not be redrawn.

Returns: IlFalse on error, that is, if set contains objects located in another container.

void IlvContainer::addTransformer ( const IlvTransformer & t )

Adds to the transformation function.

Composes the current transformer with the one given in t and sets the resulting transformer as the new current one for this container object. The transformer is internally copied during this function call.

Parameters

t	The additional transformer.

virtual void IlvContainer::afterDraw	(	IlvPort *	dst,
		const IlvTransformer *	t = `0`,
		const IlvRegion *	clip = `0`
	)

virtual

Performs a specified draw after a redraw.

Acts in the same way as beforeDraw() but is called after the objects in the container have been drawn. This lets you create additional drawings on top of the container objects.

Parameters

dst	The destination drawing port.
t	The transformation to be applied, or `0` if none.
clip	The clipping region, or `0` if none.

See Also: beforeDraw().

virtual void IlvContainer::applyToObject	(	IlvGraphic *	obj,
		IlvApplyObject	func,
		IlAny	arg,
		IlBoolean	reDraw = `IlFalse`
	)

virtual

Applies a user function to an object.

Applies the func user-defined function, typed IlvApplyObject, to the object obj which receives the additional arg parameter. You can set redraw to IlTrue to update the object's drawing automatically.

Parameters

obj	The object to which the function is applied.
func	The user function.
arg	A user argument passed with the user function.
reDraw	If set to `IlTrue` the object is redrawn. If it is set to `IlFalse`, the object will not be redrawn.

void IlvContainer::applyToObjects	(	IlvApplyObject	func,
		IlAny	arg,
		IlBoolean	redraw = `IlFalse`
	)

Applies a user function to all objects.

Applies the func user-defined function, typed IlvApplyObject, to each object of the IlvContainer which receives the additional arg parameter. You can set redraw to IlTrue to update the objects' drawing automatically.

This redraws all the objects simultaneously (and not one by one).

Parameters

func	The user function.
arg	A user argument passed with the user function.
redraw	If set to `IlTrue` the container is redrawn. If it is set to `IlFalse`, the container will not be redrawn.

void IlvContainer::applyToTaggedObjects	(	const IlSymbol *	tag,
		IlvApplyObject	func,
		IlAny	arg,
		IlBoolean	reDraw = `IlFalse`
	)

Applies a user function to all objects with a specified tag.

Calls the IlvApplyObject function func on every object tagged with tag in the container. This function is similar to the method applyToObject().

Note: For all the applyTo... member functions, you must not select nor remove an object within an applicative function, and calls to applyTo...() member functions should not be nested. Furthermore, when using these functions, you must not move an object from one layer to another.

Parameters

tag	The tag that defines the objects to be included.
func	The user function.
arg	A user argument passed with the user function.
reDraw	If set to `IlTrue` the container is redrawn. If it is set to `IlFalse`, the container will not be redrawn.

virtual void IlvContainer::beforeDraw	(	IlvPort *	dst,
		const IlvTransformer *	t = `0`,
		const IlvRegion *	clip = `0`
	)

virtual

Performs a specified draw before a redraw.

Called internally by a container just before it redraws the objects stored in it. Use this function if you need to draw something before the objects stored in the container are drawn. Use the dst parameter as the output port for your drawing functions. This may differ from the actual output port of the container.

The clip parameter gives the clipping region that should be used.

Parameters

dst	The destination drawing port.
t	The transformation to be applied, or `0` if none.
clip	The clipping region, or `0` if none.

void IlvContainer::bufferedDraw ( const IlvRect & rect )

Redraws a rectangle with double buffering.

Performs temporary drawing in a hidden pixmap, then displays the pixmap on the screen at once. The main difference with double buffering is whether the operation is localized to a rectangle (this member function), a region, or an object.

Parameters

rect	The rectangle to be redrawn with double buffering.

void IlvContainer::bufferedDraw ( const IlvRegion & region )

Redraws a region with double buffering.

Performs temporary drawing in a hidden pixmap, then displays the pixmap on the screen at once. The main difference with double buffering is whether the operation is localized to a rectangle, a region, or an object. This function draws the area included in region (in the coordinate system of the container).

Parameters

region The region to be redrawn with double buffering.

void IlvContainer::bufferedDraw ( const IlvGraphic * object )

Redraws an object with double buffering.

Performs temporary drawing in a hidden pixmap, then displays the pixmap on the screen at once. The main difference with double buffering is whether the operation is localized to a rectangle, a region, or an object. This function draws object (in the coordinate system of the object).

Parameters

object The object to be redrawn with double buffering.

IlvGraphic* IlvContainer::contains ( const IlvPoint & p ) const

Checks whether a point is in the container's objects.

Returns the topmost IlvGraphic object of this container that contains the given point, if such an object exists. If the object does not exist, the function returns 0.

Parameters

p	The point to be tested.

Returns: An object containing the given point, or 0 if there is none.

virtual IlvViewInputFile* IlvContainer::createInputFile ( istream & stream )

virtual

Creates an input file.

Creates an IlvViewInputFile from an input stream.

Parameters

stream The input stream.

Returns: An instance of the input file type corresponding to this type of container, opened in the stream stream.

void IlvContainer::disableRedrawTask ( )

Deactivates the lazy redraw mechanism.

This function prevents the lazy redraw task from happening when the process is idle.

Any subsequent call to invalidateRegion() will restore the lazy redraw mechanism and reschedule the task.

virtual IlBoolean IlvContainer::dispatchToObjects ( IlvEvent & event )

virtual

Dispatches an event to an object.

Dispatches event to an object interactor if one exists.

Parameters

event The event.

Returns: IlFalse if the event is not handled by an interactor or IlTrue if it is.

virtual void IlvContainer::draw ( const IlvRegion * clip = 0 )

virtual

Draws all objects in this container with a clipping region.

Draws all the IlvGraphic objects that are stored in this IlvContainer object.

Parameters

clip	The clipping region, or `0` if none.

Reimplemented from IlvDrawingView.

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

virtual

Draws all objects with transformation and a clipping region.

Draws all the objects that are stored in this IlvContainer in the drawing port dst, with the transformer t and the clipping region clip. This virtual function lets you draw the container contents on any destination port, with any possible drawing parameters. It was designed for dumping.

Parameters

dst	The destination drawing port.
t	The transformation to be applied, or `0` if none.
clip	The clipping region, or `0` if none.

void IlvContainer::draw ( const IlvRect * rect )

Draws all objects within a rectangle.

Creates an IlvRegion from rect and calls draw(const IlvRegion*) member function.

Parameters

rect	The initial rectangle stored in this region.

virtual void IlvContainer::eraseRegion ( const IlvRegion & region )

protectedvirtual

Erases a region.

Erases the region region.

Parameters

region The region to be erased.

virtual void IlvContainer::fitToContents ( )

virtual

Resizes the container to fit the overall bounding box of the graphic objects.

Resizes the container so it contains all the visible objects. However, the top left coordinates of the view remain at the same location.

virtual void IlvContainer::fitTransformerToContents ( IlBoolean redraw = IlTrue )

virtual

Resizes the objects to fit the container.

Computes a new transformer (scaling and translation only) for this container so that all objects that have the visibility attribute set to IlTrue can be seen in the view.

The computation is not always accurate: it assumes that the bounding box of a transformed graphic object is equal to the transformed bounding box, which is not true for non-zoomable objects. If there are such objects in the container, several calls to the method may be necessary to obtain the desired result.

Parameters

redraw If set to IlTrue the container is redrawn after the transformation. If it is set to IlFalse, the container will not be redrawn.

virtual void IlvContainer::flushRedraw ( )

virtual

Performs the actual redraw of invalid regions.

This function is called as an idle procedure just before a process becomes idle to handle all pending drawing tasks accumulated by calls to invalidateRegion(). You can call it if you want to force the refresh of your view at a given point in your program.

See Also: IlvEventLoop::addIdleProc().

Reimplemented from IlvPort.

		IlUShort	button = `0`,
		IlUShort	modifiers = `0`
	)		const

Gets an accelerator by event.

Returns a pointer to the IlvContainerAccelerator instance that matches this event. If an accelerator to match this event does not exist, then 0 is returned.

		IlUShort	buttonOrKey = `0`,
		IlUShort	modifiers = `0`
	)		const

Gets an accelerator by action and user argument.

Queries a container for a particular accelerator action and user argument. This function returns IlTrue if this accelerator exists in the container and fills in the action and userArg parameters if they are valid pointers (that is, non-0).

If no such accelerator exists, it returns IlFalse. You can thus test the existence of a particular accelerator by calling the member function getAccelerator() with 0 values for both action and userArg.

Replaces the IlvGraphic instance oldObject by the IlvGraphic object newObject. If redraw is IlTrue, the reDrawObj() member function of newObject is called.

Parameters

oldObject	The object to be replaced.
newObject	The new object.
redraw	If set to `IlTrue` the container is redrawn. If it is set to `IlFalse`, the container will not be redrawn.

virtual void IlvContainer::setBackground ( IlvColor * c )

virtual

Sets the background color of this view.

The color is used when erasing is required. Thus, a call to setBackground is effective only when regions are erased.

Parameters

c	The new background color of this view. This color is locked, and the previous color is unlocked.

Reimplemented from IlvAbstractView.

virtual void IlvContainer::setBackgroundBitmap ( IlvBitmap * b )

virtual

Sets the background bitmap of this view.

The bitmap provided (if it is not 0) is locked. The previous bitmap, if there was one, is unlocked. If the bitmap provided is 0, the background color is used to ( erase the view. To remove properly a background bitmap that was previously set, you must do the following:

view->setBackgroundBitmap(0); // Remove the background bitmap
manager->setBackground(view, view->getBackground()); // Update manager
manager->draw(view, IlTrue); // Redraw the view

This code must be used also for containers (replaces manager by container in code).

Note: There is a limitation on Windows 95, because Windows 95 can only handle bitmaps with a size of 8x8.

Reimplemented from IlvAbstractView.

IlBoolean IlvContainer::setDoubleBuffering ( IlBoolean value )

Sets double buffering.

Use this member function to indicate whether or not this container should use double buffering.

Parameters

value Indicates if this container should use double buffering (IlTrue) or not (IlFalse).

IlBoolean IlvContainer::setObjectInteractor	(	IlvGraphic *	,
		IlvViewObjectInteractor *
	)

Sets an object interactor on a graphic object.

This method is obsolete. Use IlvGraphic::setInteractor().

See Also: IlvGraphic::setInteractor().

virtual void IlvContainer::setObjectName	(	IlvGraphic *	obj,
		const char *	name
	)

virtual

Sets the name of an object.

You are allowed to give the same name to two different objects but the method getObject(const char*) will then return the first object whose name is name.

Parameters

obj	The object.
name	The name to be given to obj. This string is copied.

virtual void IlvContainer::setTransformer ( const IlvTransformer & t )

virtual

Applies another transformer to the coordinates provided for the drawing functions.

Parameters

t	The transformer that is applied.

Reimplemented from IlvSystemPort.

void IlvContainer::setTransformer ( const IlvTransformer * t = 0 )

Sets the transformation function.

Sets the transformer associated with the container view. A 0 value means no transformer, that is, the identity transformer. The transformer is internally copied during this function call.

Parameters

t	The transformation to be applied, or `0` if none.

virtual void IlvContainer::setVisible	(	IlvGraphic *	obj,
		IlBoolean	visible,
		IlBoolean	redraw = `IlFalse`
	)

virtual

Sets the visibility of an object.

This method only works with an object that is already in this container.

Parameters

obj	The object.
visible	Indicates whether the object is to be visible (`IlTrue`) or invisible (`IlFalse`).
redraw	If set to `IlTrue` the container is redrawn. If it is set to `IlFalse`, the container will not be redrawn.

virtual IlBoolean IlvContainer::shortCut ( IlvEvent & event )

virtual

Verbose:

Dispatches event to an accelerator.

Parameters

event The incoming event.

Returns: IlTrue if the accelerator exists; otherwise, it returns IlFalse.

virtual void IlvContainer::show ( )

virtual

Shows the view.

Displays the window on the screen. A window can be created in such a way that you cannot see it upon creation, which allows you to draw on that window before it is displayed.

Reimplemented from IlvView.

virtual void IlvContainer::swap	(	IlvGraphic *	obj1,
		IlvGraphic *	obj2
	)

virtual

Swaps two objects.

Interchanges the two objects obj1 and obj2 with respect to their order in the list of objects of the container, thus modifying the order in which objects are stacked.

Parameters

obj1	The first object.
obj2	The second object.

void IlvContainer::translateView	(	IlvPos	dx,
		IlvPos	dy,
		IlBoolean	redraw = `IlTrue`
	)

Translates the current view.

Composes the current transformer with a translation specified by dx and dy. Set the redraw parameter to IlFalse to prevent an immediate display update.

Parameters

dx	Translation along the horizontal axis.
dy	Translation along the vertical axis.
redraw	If set to `IlTrue` the container is redrawn after the transformation. If it is set to `IlFalse`, the container will not be redrawn.

void IlvContainer::unregisterCallback ( const char * callbackName )

Unregisters a callback.

Removes the callback function which has been registered with the name callbackName, from the callback list.

Parameters

callbackName The name of the callback to be removed.

void IlvContainer::visibleBBox ( IlvRect & bbox ) const

Determines the visible bounding box of the container.

Returns the bounding box of all visible objects in the view coordinate system.

Parameters

bbox	The returned visible bounding box.

void IlvContainer::zoomView	(	const IlvPoint &	center,
		IlFloat	scaleX,
		IlFloat	scaleY = `0.0`,
		IlBoolean	redraw = `IlTrue`
	)

Zooms the current view.

Composes the current transformer with a transformer that zooms by a factor of scaleX and scaleY, and leaves the center point in the container at its original place. If scaleY is 0, then we assume the scaling factor is the same in y as in x. Set the redraw parameter to IlFalse to prevent an immediate display update.

Parameters

center	The center point of the transformation.
scaleX	Zooming factor on the horizontal axis.
scaleY	Zooming factor on the vertical axis.
redraw	If set to `IlTrue` the container is redrawn after the transformation. If it is set to `IlFalse`, the container will not be redrawn.
