Detailed Description

Abstract view provide interactors' functions.

Abstract view provide a View with interactors' basic functions like getInteractors, pushInteractor and popInteractor You can inherit from it if you want this functions In tulip-qt GlMainView inherit from it

Member Function Documentation

virtual void tlp::AbstractView::buildContextMenu	(	QObject *	,
		QContextMenuEvent *	,
		QMenu *	contextMenu
	)			[protected, virtual]

empty function : implement this function if you want a context menu when you right click the mouse

Reimplemented in tlp::GlMainView, and tlp::NodeLinkDiagramComponent.

virtual void tlp::AbstractView::computeContextMenuAction

(

QAction *

)

[inline, protected, virtual]

empty function : implement this function if you have implement buildContextMenu()

Reimplemented in tlp::NodeLinkDiagramComponent.

virtual QWidget* tlp::AbstractView::construct

(

QWidget *

parent

)

[virtual]

Construct the abstract view

Warning:

If you want to inherit from it, you must call AbstractView::construct(QWidget *) in your new construct function

Implements tlp::View.

Reimplemented in tlp::BaseGraphicsViewComponent, tlp::GlMainView, and tlp::NodeLinkDiagramComponent.

bool tlp::AbstractView::eventFilter	(	QObject *	object,
		QEvent *	event
	)			[slot]

this function is call by Qt this function call specificEventFilter, buildContextMenu and computeContextMenu

virtual void tlp::AbstractView::exportImage

(

QAction *

action

)

[virtual, slot]

Interactor* tlp::AbstractView::getActiveInteractor

(

)

[inline, virtual]

return current interactor

Implements tlp::View.

QWidget* tlp::AbstractView::getCentralWidget

(

)

const [inline]

Returns:

the central widget of the abstract view

virtual std::list<Interactor *> tlp::AbstractView::getInteractors

(

)

[virtual]

Return interactors of this view

Implements tlp::View.

Reimplemented in tlp::BaseGraphicsViewComponent.

QWidget* tlp::AbstractView::getWidget

(

)

[inline, virtual]

get the widget who will be add to workspace by the controller

Returns:

the widget of the abstract view

Implements tlp::View.

bool tlp::AbstractView::savePicture	(	const std::string &	pictureName,
		int	width,
		int	height,
		bool	center,
		int	zoom = 1,
		int	xOffset = 0,
		int	yOffset = 0
	)			[virtual]

Default implementation of the savePicture function. Use the image objects returned by the createPicture function and save it to a picture file on disk.

Parameters:

	pictureName	: filename to use for the picture, with extension (extension is used to infer image type).
	width	: width of the picture
	height	: height of the picture
	center	: whether we should center the view before creating the picture, or use the current zoom and pan.
	zoom	: creates a picture of a sub part of the view. With zoom=1 creates only one picture with entire view; with zoom=N : the view is cut into 2^(N-1) part in width and height. Defaults to 1.
	xOffset	: which part of the view to render if zoom!=1. xOffset must be 0 <= xOffset < 2^(zoom-1). Defaults to 0.
	yOffset	: which part of the view to render if zoom!=1. yOffset must be 0 <= yOffset < 2^(zoom-1). Defaults to 0.

Returns:

bool : Whether the picture can be created or not.

Reimplemented from tlp::View.

Reimplemented in tlp::BaseGraphicsViewComponent.

virtual void tlp::AbstractView::setActiveInteractor

(

Interactor *

interactor

)

[virtual]

Set active interactor on this view

Implements tlp::View.

Reimplemented in tlp::BaseGraphicsViewComponent.

void tlp::AbstractView::setCentralWidget

(

QWidget *

widget

)

[protected]

set the central widget of the view call this function to set view's centralWidget

virtual void tlp::AbstractView::setInteractors

(

const std::list< Interactor * > &

interactorsList

)

[virtual]

Set all interactors available forthis view Interactors are create (allocate) but now view have responsibility of her destruction

Implements tlp::View.

Reimplemented in tlp::BaseGraphicsViewComponent.

virtual void tlp::AbstractView::specificEventFilter	(	QObject *	,
		QEvent *
	)			[inline, protected, virtual]

empty function : implement this function if you want a specific event filter in your view

Reimplemented in tlp::NodeLinkDiagramComponent.
