Member Function Documentation

virtual bool vtkQtChartMouseFunction::isCombinable

(

)

const [inline, virtual]

Gets whether or not the function is combinable.

If a function can be combined with other functions on the same mouse button mode, this method should return true. Functions are combined using keyboard modifiers. If a function uses the keyboard modifiers, it should return false.

Returns:

True if the other functions can be combined with this one.

Reimplemented in vtkQtChartMouseSelection.

Definition at line 63 of file vtkQtChartMouseFunction.h.

bool vtkQtChartMouseFunction::isMouseOwner

(

)

const [inline]

Gets whether or not the function owns the mouse.

Returns:

True if the function owns the mouse.

Definition at line 69 of file vtkQtChartMouseFunction.h.

virtual void vtkQtChartMouseFunction::setMouseOwner

(

bool

owns

)

[inline, virtual]

Sets whether or not the function owns the mouse.

Parameters:

owns

True if the function owns the mouse.

Reimplemented in vtkQtChartMousePan, vtkQtChartMouseZoom, and vtkQtChartMouseZoomBox.

Definition at line 76 of file vtkQtChartMouseFunction.h.

virtual bool vtkQtChartMouseFunction::mousePressEvent	(	QMouseEvent *	e,
		vtkQtChartArea *	chart
	)			[pure virtual]

Called to handle the mouse press event.

Parameters:

	e	Event specific information.
	chart	The chart area.

Returns:

True if the event was used.

Implemented in vtkQtChartMousePan, vtkQtChartMouseSelection, vtkQtChartMouseZoom, and vtkQtChartMouseZoomBox.

virtual bool vtkQtChartMouseFunction::mouseMoveEvent	(	QMouseEvent *	e,
		vtkQtChartArea *	chart
	)			[pure virtual]

Called to handle the mouse move event.

Parameters:

	e	Event specific information.
	chart	The chart area.

Returns:

True if the event was used.

Implemented in vtkQtChartMousePan, vtkQtChartMouseSelection, vtkQtChartMouseZoom, and vtkQtChartMouseZoomBox.

virtual bool vtkQtChartMouseFunction::mouseReleaseEvent	(	QMouseEvent *	e,
		vtkQtChartArea *	chart
	)			[pure virtual]

Called to handle the mouse release event.

Parameters:

	e	Event specific information.
	chart	The chart area.

Returns:

True if the event was used.

Implemented in vtkQtChartMousePan, vtkQtChartMouseSelection, vtkQtChartMouseZoom, and vtkQtChartMouseZoomBox.

virtual bool vtkQtChartMouseFunction::mouseDoubleClickEvent	(	QMouseEvent *	e,
		vtkQtChartArea *	chart
	)			[pure virtual]

Called to handle the double click event.

Parameters:

	e	Event specific information.
	chart	The chart area.

Returns:

True if the event was used.

Implemented in vtkQtChartMousePan, vtkQtChartMouseSelection, vtkQtChartMouseZoom, and vtkQtChartMouseZoomBox.

virtual bool vtkQtChartMouseFunction::wheelEvent	(	QWheelEvent *	e,
		vtkQtChartArea *	chart
	)			[virtual]

Called to handle the wheel event.

Parameters:

	e	Event specific information.
	chart	The chart area.

Returns:

True if the event was used.

Reimplemented in vtkQtChartMouseZoom.

void vtkQtChartMouseFunction::interactionStarted

(

vtkQtChartMouseFunction *

function

)

[signal]

Emitted when a function interaction has started.

A mouse function should not assume it has ownership after emitting this signal. The interactor will call setMouseOwner if no other function owns the mouse.

Parameters:

function

The function requesting mouse ownership.

void vtkQtChartMouseFunction::interactionFinished

(

vtkQtChartMouseFunction *

function

)

[signal]

Emitted when a function has finished an interaction state.

Parameters:

function

The function releasing mouse control.

void vtkQtChartMouseFunction::cursorChangeRequested

(

const QCursor &

cursor

)

[signal]

Emitted when the mouse cursor needs to be changed.

Parameters:

cursor

The new cursor to use.
