The region can be dragged and is bounded by lines which can be dragged individually. =============================== ============================================================================= **Signals:** sigRegionChangeFinished(self) Emitted when the user has finished dragging the region (or one of its lines) and when the region is changed programatically. sigRegionChanged(self) Emitted while the user is dragging the region (or one of its lines) and when the region is changed programatically. =============================== ============================================================================= rvertical horizontalNc tj|||_d|_d|_d|_| |_| |_| |_d|_ d|_ t||| ||} |dtjfvrttj d|dfddi| ttj d|dfddi| g|_t$j&j)dd} |j"dj+| d |j"dj+| d no|d tj,fvrPttj |ddfdd i| ttj |ddfdd i| g|_n t/d |j"D]8}|j1||j2j5|j6:|j"dj8j5|j:|j"dj8j5|j<|+t%j>t%j@ddd d}|jC||[|jDjG}|jItK|jMdzd tOjP|}|jS||jU|y)aJ Create a new LinearRegionItem. ============== ===================================================================== **Arguments:** values A list of the positions of the lines in the region. These are not limits; limits can be set by specifying bounds. orientation Options are 'vertical' or 'horizontal' The default is 'vertical', indicating that the region is bounded by vertical lines. brush Defines the brush that fills the region. Can be any arguments that are valid for :func:`mkBrush `. Default is transparent blue. pen The pen to use when drawing the lines that bound the region. hoverBrush The brush to use when the mouse is hovering over the region. hoverPen The pen to use when the mouse is hovering over the region. movable If True, the region and individual lines are movable by the user; if False, they are static. bounds Optional [min, max] bounding values for the region span Optional [min, max] giving the range over the view to draw the region. For example, with a vertical line, use ``span=(0.5, 1)`` to draw only on the top half of the view. swapMode Sets the behavior of the region when the lines are moved such that their order reverses: * "block" means the user cannot drag one line past the other * "push" causes both lines to be moved if one would cross the other * "sort" means that lines may trade places, but the output of getRegion always gives the line positions in ascending order. * None means that no attempt is made to handle swapped line positions. The default is "sort". clipItem An item whose bounds will be used to limit the region bounds. This is useful when a LinearRegionItem is added on top of an :class:`~pyqtgraph.ImageItem` or :class:`~pyqtgraph.PlotDataItem` and the visual region should not extend beyond its range. This overrides ``bounds``. ============== ===================================================================== FN)movableboundsspanpenhoverPenrr anglerTr Zz/Orientation must be 'vertical' or 'horizontal'.2r)+r__init__ orientationblockLineSignalmoving mouseHoveringrswapModeclipItem_boundingRectCache_clipItemBoundsCachedictr Horizontalr rQPointFlinesr QTransform fromScale setTransformVertical Exception setParentItemsigPositionChangeFinishedconnectlineMoveFinishedsigPositionChanged _line0Moved _line1MovedQBrushQColorsetBrushbrushcolorsetAlphaminalphafnmkBrush setHoverBrush setMovable)selfvaluesrr6r hoverBrushrrrrrr lineKwdstrlcs J/usr/lib/python3/dist-packages/pyqtgraph/graphicsItems/LinearRegionItem.pyrzLinearRegionItem.__init__$sX %&$ "     "&$(!   <)9)D)DE E V^^Avay9OOhOV^^Avay9OOhO QDJ!!++Ar2B JJqM & &r4 0 JJqM & &r4 0 Z)9)B)BC CV^^F1Iq9PPxPV^^F1Iq9PPxPRDJMN N GA OOD !
