TaurusGraphicsScene

Inheritance diagram of TaurusGraphicsScene
class TaurusGraphicsScene(parent=None, strt=True)[source]

Bases: PyQt4.QtGui.QGraphicsScene

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.
ANY_ATTRIBUTE_SELECTS_DEVICE = True
TRACE_ALL = False
addItem(item)[source]
addWidget(item, flags=None)[source]
clearSelection()[source]
closeAllPanels()[source]

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

drawSelectionMark(x, y, w, h, oversize=1)[source]

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)[source]

Returns all children elements, filtering by klass if wanted

getClass(clName)[source]
getItemByName(item_name, strict=None)[source]

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
Return type:list
Returns:items
getItemByPosition(x, y)[source]

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

getItemClicked(mouseEvent)[source]
getQueue()[source]
getSelectionMark(picture=None, w=10, h=10)[source]
getShellCommand(obj, wait=False)[source]
static getTaurusParentItem(item, top=True)[source]

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

graphicItemSelected
graphicSceneClicked
mouseDoubleClickEvent(event)[source]
mousePressEvent(mouseEvent)[source]
refreshTree2
selectGraphicItem(item_name)[source]

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)[source]

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.
