QList< QPoint > Isis::RubberBandTool::getFoundVertices ( )

This method returns the vertices.

The return value is mode-specific, and the return will be consistent whether in a measureChange or bandingComplete slot.

The return values are always in pixels.

The return values are as follows: For angles, the return will always be of size 3. The elements at 0 and 2 are the edges of the angle, while the element at 1 is the vertex of the angle.

For circles, the return will always be of size 2. The element at 0 is the center of the circle, and the element at 1 is offset by the radius in both directions.

For Ellipses, the return will always be of size 2. The element at 0 is the center of the circle, and the element at 1 is offset by the radius in both directions.

For lines, the return will always be of size 2. The elements are the start and end points.

For rectangles, the return will always be of size 4. The elements will be the corners, in either a clockwise or counter-clockwise direction.

For rotated rectangles, the same applies.

For polygons, the return will be a list of vertices in the order that the user drew them.

**It is NOT valid to call this unless you're in a measureChange or bandingComplete slot.

Returns:: QList<QPoint>

RubberBandTool * Isis::RubberBandTool::getInstance ( QWidget * parent = NULL ) [static]

This method returns the singleton instance of the rubber band tool.

The first call to this method must have the optional argument *parent so the tool can properly initialize. After this tool is created, *parent is ignored.

Parameters:

parent

A pointer to the main window for the tool to properly initialize

Returns:: RubberBandTool* An instance of the rubber band tool

Returns:: MouseButton Mouse button modifier on last release

Definition at line 1035 of file RubberBandTool.cpp.

QRect Isis::RubberBandTool::getRectangle ( )

This method returns a rectangle from the vertices set by the RubberBandTool.

It calculates the upper left and bottom right points for the rectangle and properly initializes a QRect object with these vertices. If the RubberBandTool is in the incorrect mode, or the rectangle is not valid it will return an error message.

Returns:: QRect The QRect the user selected on the viewport in pixels

void Isis::RubberBandTool::mouseButtonPress	(	QPoint	p,
		Qt::MouseButton	s
	)			`[protected, virtual, slot]`

If the click is not the left mouse button, this does nothing.

This will set mouseDown as true. When the calculations are complete, p_mouseDown is set to true.

For drag-only, A press means starting a new rubber band so reset & record the point. This applies to Circles, Eliipsoids, Lines and Rectangles.

For Rotated Rectangles, A mount press means we're starting over, setting the first point, or completing. For the first two, simply reset and record the point. For the latter, figure out the corners and store those points.

For polygons, A press means record the current point. Reset first if we're not currently drawing.

Parameters:

	p
	s

Reimplemented from Isis::Tool.

Definition at line 411 of file RubberBandTool.cpp.

References reset().

void Isis::RubberBandTool::mouseButtonRelease	(	QPoint	p,
		Qt::MouseButton	s
	)			`[protected, virtual, slot]`

If this is not the left mouse button, this does nothing.

This will set mouseDown as false. When the calculations are complete, p_doubleClicking is set to false. The double click event occurs with `the press event so it's safe to set that flag here.

The implementation differs, based on the mode, as follows:

For angles, This signifies a click. We're always setting one of the three vertexes, but if there is an already complete vertex go ahead and reset first to start a new angle.

For circles, Since this is a drag-only rubber band, a release signifies a complete. Figure out the corner, based on the mouse location, and push it onto the back of the vertex list and emit a complete.

For Ellipses, Since this is a drag-only rubber band, a release signifies a complete. We know the corner, it's the mouse loc, push it onto the back of the vertex list and emit a complete.

For lines, Since this is a drag-only rubber band, a release signifies a complete. We know the end point, push it onto the back of the vertex list and emit a complete.

For rectangles, Since this is a drag-only rubber band, a release signifies a complete. We know the opposite corner, figure out the others and push them onto the back of the vertex list and emit a complete.

For rotated rectangles, If we're finishing dragging the first side, store the end point.

For polygons, Do nothing, this is taken care of on press.

Parameters:

	p	Current mouse Location
	s	Which mouse button was released

void Isis::RubberBandTool::mouseDoubleClick ( QPoint p ) [protected, virtual, slot]

This triggers on a second mouse press.

Only polygons care about this, and it signifies an end of shape. So, if we're in polygon mode, stop tracking the mouse and emit a complete.

Parameters:

p

void Isis::RubberBandTool::mouseMove	(	QPoint	p,
		Qt::MouseButton	mouseButton
	)			`[protected, virtual, slot]`

If tracking is not enabled, this does nothing.

This will first update the mouse location for painting purposes.

Most of the implementation is a matter of emitting measureChanges: For angles, if the first two vertices are specified a measureChange will be emitted. For circles, if the center of the circle is known a measureChange will be emitted. For Ellipses, if the center of the Ellipse is known a measureChange will be emitted. For lines, if the first point of the line is known a measureChange will be emitted. For rectangles, if the starting point is known a measureChange will be emitted. For rotated rectangles, if the first side is specified a measureChange will be emitted.

However, there is one exception: For polygons, if the mouse button is pressed the mouse location is recorded as a valid vertex.

Parameters:

p

Current mouse Location

void Isis::RubberBandTool::paintViewport	(	MdiCubeViewport *	vp,
		QPainter *	painter
	)			`[virtual]`

This is the main paint method for the rubber bands.

For angles and lines, simply connect the known vertices.vertices[0].x() For polygons, paint the vertices & close if completed the shape. For circles, figure out the circle's square and draw the circle inside of it. For Ellipses, figure out the Ellipse's rectangle and draw the circle inside of it. For rectangles, paint the rectangle either to the mouse or back to the start depending on if the shape is complete. For rotated rectangles, if we can interpolate extra sides draw them and draw all known sides.

Parameters:
