virtual const char* vtkBlockItem::GetClassName

(

)

[virtual]

Reimplemented from vtkContextItem.

static int vtkBlockItem::IsTypeOf

(

const char *

name

)

[static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkContextItem.

virtual int vtkBlockItem::IsA

(

const char *

name

)

[virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkContextItem.

static vtkBlockItem* vtkBlockItem::SafeDownCast

(

vtkObject *

o

)

[static]

Reimplemented from vtkContextItem.

virtual void vtkBlockItem::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)			[virtual]

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkContextItem.

static vtkBlockItem* vtkBlockItem::New

(

)

[static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

virtual bool vtkBlockItem::Paint

(

vtkContext2D *

painter

)

[virtual]

Paint event for the item.

Reimplemented from vtkAbstractContextItem.

virtual bool vtkBlockItem::Hit

(

const vtkContextMouseEvent &

mouse

)

[virtual]

Returns true if the supplied x, y coordinate is inside the item.

Reimplemented from vtkAbstractContextItem.

virtual bool vtkBlockItem::MouseEnterEvent

(

const vtkContextMouseEvent &

mouse

)

[virtual]

Mouse enter event.

Reimplemented from vtkAbstractContextItem.

virtual bool vtkBlockItem::MouseMoveEvent

(

const vtkContextMouseEvent &

mouse

)

[virtual]

Mouse move event.

Reimplemented from vtkAbstractContextItem.

virtual bool vtkBlockItem::MouseLeaveEvent

(

const vtkContextMouseEvent &

mouse

)

[virtual]

Mouse leave event.

Reimplemented from vtkAbstractContextItem.

virtual bool vtkBlockItem::MouseButtonPressEvent

(

const vtkContextMouseEvent &

mouse

)

[virtual]

Mouse button down event.

Reimplemented from vtkAbstractContextItem.

virtual bool vtkBlockItem::MouseButtonReleaseEvent

(

const vtkContextMouseEvent &

mouse

)

[virtual]

Mouse button release event.

Reimplemented from vtkAbstractContextItem.

virtual void vtkBlockItem::SetLabel

(

const vtkStdString &

label

)

[virtual]

Set the block label.

virtual vtkStdString vtkBlockItem::GetLabel

(

)

[virtual]

Get the block label.

virtual void vtkBlockItem::SetDimensions	(	int	,
		int	,
		int	,
		int
	)			[virtual]

Set the dimensions of the block, elements 0 and 1 are the x and y coordinate of the bottom corner. Elements 2 and 3 are the width and height. Initial value is (0,0,0,0).

virtual void vtkBlockItem::SetDimensions

(

int

[4]

)

[virtual]

Set the dimensions of the block, elements 0 and 1 are the x and y coordinate of the bottom corner. Elements 2 and 3 are the width and height. Initial value is (0,0,0,0).

virtual int* vtkBlockItem::GetDimensions

(

)

[virtual]

Get the dimensions of the block, elements 0 and 1 are the x and y coordinate of the bottom corner. Elements 2 and 3 are the width and height. Initial value is (0,0,0,0)

virtual void vtkBlockItem::GetDimensions	(	int &	,
		int &	,
		int &	,
		int &
	)			[virtual]

Get the dimensions of the block, elements 0 and 1 are the x and y coordinate of the bottom corner. Elements 2 and 3 are the width and height. Initial value is (0,0,0,0)

virtual void vtkBlockItem::GetDimensions

(

int

[4]

)

[virtual]

Get the dimensions of the block, elements 0 and 1 are the x and y coordinate of the bottom corner. Elements 2 and 3 are the width and height. Initial value is (0,0,0,0)
