TaurusGraphicsScene

class TaurusGraphicsScene(parent=None, strt=True)

This class encapsulates TaurusJDrawSynopticsView and TaurusGraphicsScene signals/slots

External events:

Slot selectGraphicItem(const QString &) displays a selection
mark around the TaurusGraphicsItem that matches the argument passed.

Mouse Left-button events:

Signal graphicItemSelected(QString) is triggered, passing the
selected TaurusGraphicsItem.name() as argument.

Mouse Right-button events:

TaurusGraphicsItem.setContextMenu([(ActionName,ActionMethod(device_name))]
allows to configure custom context menus for graphic items using a list
of tuples. Empty tuples will insert separators in the menu.

Import from taurus.qt.qtgui.graphic as:

from taurus.qt.qtgui.graphic import TaurusGraphicsScene

ANY_ATTRIBUTE_SELECTS_DEVICE = True

TRACE_ALL = False

addItem(self, item: Optional[QGraphicsItem])

addWidget(self, widget: Optional[QWidget], flags: Qt.WindowFlags | Qt.WindowType = Qt.WindowFlags()) → Optional[QGraphicsProxyWidget]

clearSelection(self)

closeAllPanels()

This method replaces killProcess, using taurus.qt.qtgui.util.ExternalAppAction instead!

drawSelectionMark(x, y, w, h, oversize=1)

If h or w are None the mark is drawn at x,y If h or w has a value the mark is drawn in the center of the region ((x,y)(x+w,y+h))

getAllChildren(item, klass=None)

Returns all children elements, filtering by klass if wanted

getClass(clName)

getItemByName(item_name, strict=None)

Returns a list with all items matching a given name.

Parameters:

strict (bool or None) – controls whether full_name (strict=True) or only device name (False) must match

Returns:

items

Return type:

list

getItemByPosition(x, y)

This method will try first with named objects; if failed then with itemAt

getItemClicked(mouseEvent)

getQueue()

getSelectionMark(picture=None, w=10, h=10)

getShellCommand(obj, wait=False)

static getTaurusParentItem(item, top=True)

Searches within a group hierarchy and returns a parent Taurus component or None if no parent TaurusBaseComponent is found.

graphicItemSelected

graphicSceneClicked

mouseDoubleClickEvent(self, event: Optional[QGraphicsSceneMouseEvent])

mousePressEvent(self, event: Optional[QGraphicsSceneMouseEvent])

selectGraphicItem(item_name)

A blue circle is drawn around the matching item name. If the item_name is empty, or it is a reserved keyword, or it has the “noSelect” extension, then the blue circle is removed from the synoptic.

setSelectionMark(picture=None, w=10, h=10)

This method allows to set a callable, graphic item or pixmap as selection mark (by default creates a blue circle). If picture is a callable, the object returned will be used as selection mark. If picture is a QGraphicsItem it will be used as selection mark. If picture is a QPixmap or a path to a pixmap a QGraphicsPixmapItem will be created. If no picture is provided, a blue ellipse will be drawn around the selected object. h/w will be used for height/width of the drawn object.
