Can be used for implementing many types of selection box with rotate/translate/scale handles. ROIs can be customized to have a variety of shapes (by subclassing or using any of the built-in subclasses) and any combination of draggable handles that allow the user to manipulate the ROI. Default mouse interaction: * Left drag moves the ROI * Left drag + Ctrl moves the ROI with position snapping * Left drag + Alt rotates the ROI * Left drag + Alt + Ctrl rotates the ROI with angle snapping * Left drag + Shift scales the ROI * Left drag + Shift + Ctrl scales the ROI with size snapping In addition to the above interaction modes, it is possible to attach any number of handles to the ROI that can be dragged to change the ROI in various ways (see the ROI.add____Handle methods). ================ =========================================================== **Arguments** pos (length-2 sequence) Indicates the position of the ROI's origin. For most ROIs, this is the lower-left corner of its bounding rectangle. size (length-2 sequence) Indicates the width and height of the ROI. angle (float) The rotation of the ROI in degrees. Default is 0. invertible (bool) If True, the user may resize the ROI to have negative width or height (assuming the ROI has scale handles). Default is False. maxBounds (QRect, QRectF, or None) Specifies boundaries that the ROI cannot be dragged outside of by the user. Default is None. snapSize (float) The spacing of snap positions used when *scaleSnap* or *translateSnap* are enabled. Default is 1.0. scaleSnap (bool) If True, the width and height of the ROI are forced to be integer multiples of *snapSize* when being resized by the user. Default is False. translateSnap (bool) If True, the x and y positions of the ROI are forced to be integer multiples of *snapSize* when being resized by the user. Default is False. rotateSnap (bool) If True, the ROI angle is forced to a multiple of the ROI's snap angle (default is 15 degrees) when rotated by the user. Default is False. parent (QGraphicsItem) The graphics item parent of this ROI. It is generally not necessary to specify the parent. pen (QPen or argument to pg.mkPen) The pen to use when drawing the shape of the ROI. hoverPen (QPen or argument to mkPen) The pen to use while the mouse is hovering over the ROI shape. handlePen (QPen or argument to mkPen) The pen to use when drawing the ROI handles. handleHoverPen (QPen or argument to mkPen) The pen to use while the mouse is hovering over an ROI handle. movable (bool) If True, the ROI can be moved by dragging anywhere inside the ROI. Default is True. rotatable (bool) If True, the ROI can be rotated by mouse drag + ALT resizable (bool) If True, the ROI can be resized by mouse drag + SHIFT removable (bool) If True, the ROI will be given a context menu with an option to remove the ROI. The ROI emits sigRemoveRequested when this menu action is selected. Default is False. ================ =========================================================== ======================= ==================================================== **Signals** sigRegionChangeFinished Emitted when the user stops dragging the ROI (or one of its handles) or if the ROI is changed programatically. sigRegionChangeStarted Emitted when the user starts dragging the ROI (or one of its handles). sigRegionChanged Emitted any time the position of the ROI changes, including while it is being dragged by the user. sigHoverEvent Emitted when the mouse hovers over the ROI. sigClicked Emitted when the user clicks on the ROI. Note that clicking is disabled by default to prevent stealing clicks from objects behind the ROI. To enable clicking, call roi.setAcceptedMouseButtons(QtCore.Qt.MouseButton.LeftButton). See QtWidgets.QGraphicsItem documentation for more details. sigRemoveRequested Emitted when the user selects 'remove' from the ROI's context menu (if available). ======================= ==================================================== rgFN?Tcxtj|| |jtjj j t|}t|}||_||_ ||_ ||_ ||_ d|_ d|_d|_| d} |j!| | d} t#j$| |_| d} t#j$| |_|d}||_g|_tddtdddd|_d|_|j3||j5||j7||j9dd|_d |_||_||_ ||_!||_"| |_#d |_$||_%||_&tO||_(y) NF)r*r*r*r*r)r*r*rr)possizeangle g.@))r__init__setAcceptedMouseButtonsr Qt MouseButtonNoButtonr aspectLocked translatable rotatable resizable removablemenufreeHandleMoved mouseHoveringsetPenfnmkPenhoverPen handlePenhandleHoverPenhandlesstate lastStatesetPossetAnglesetSize setZValueisMoving handleSize invertible maxBoundssnapSize translateSnap rotateSnaprotateSnapAngle scaleSnap scaleSnapSizeMouseDragHandlermouseDragHandler)selfr-r.r/rNrOrPrTrQrRparentpenrBrCrDmovabler9r:r;r7s r$r2z ROI.__init__s f- $$VYY%:%:%C%CDCjT{(#""" $" ;!C C  $H*  'I),  !*N, "1QZqaH  C e T r $"  *$#"%!1 6r&c"|jSN) stateCopyrXs r$getStatez ROI.getStates~~r&ci}t|jd|d<t|jd|d<|jd|d<|S)Nr-r.r/)r rF)rXscs r$r^z ROI.stateCopysL $**U+,5 4::f-.6 jj)7  r&ci}t|jd|d<t|jd|d<|jd|d<|S)zReturn the state of the widget in a format suitable for storing to disk.

Accepts either separate (x, y) arguments or a single :class:`Point` or ``QPointF`` argument. By default, this method causes both ``sigRegionChanged`` and ``sigRegionChangeFinished`` to be emitted. If *finish* is False, then ``sigRegionChangeFinished`` will not be emitted. You can then use stateChangeFinished() to cause the signal to be emitted after a series of state changes. If *update* is False, the state change will be remembered but not processed and no signals will be emitted. You can then use stateChanged() to complete the state change. This allows multiple change functions to be called sequentially while minimizing processing overhead and repeated signals. Setting ``update=False`` also forces ``finish=False``.

They are usually created by a call to one of the ROI.add___Handle() methods. Handles are represented as a square, diamond, or circle, and are drawn with fixed pixel size regardless of the scaling of the view they are displayed in. Handles may be dragged to change the position, size, orientation, or other properties of the ROI they are attached to. )rr) r)rrrr#rrNcg|_||_||_tj||_tj||_|j |_|j jd|j jdd|_ |j|\|_ |_ |jd|_|j!|_t%j&|||j)t*j,j.j0||_|r3|j)t*j,j.j4|j7dy)NrTF)rY )rradiusrr@rArZrBrusetWidth setCosmeticrLtypessidesstartAng buildPathr buildMenur<rr2r3r r4r5r6 deletablerrK)rXrrrZrBrYrs r$r2zHandle.__init__9s  88C=* (( !
