I have solved it this way:
class MousePosition(QtCore.QObject):
def __init__(self, status_bar, pl, labels):
super().__init__()
self.pl = pl
self.status_bar = status_bar
self.labels = labels
self.proxy = pg.SignalProxy(pl.scene().sigMouseMoved, rateLimit=10,
slot=self.mousemoved)
def mousemoved(self, evt):
pos = evt[0]
if self.pl.sceneBoundingRect().contains(pos):
mousePoint = self.pl.vb.mapSceneToView(pos)
self.status_bar.set_x(mousePoint.x(),self.labels[0])
self.status_bar.set_y(mousePoint.y(),self.labels[1])
class StatusBarKK3:
def __init__(self, window, plots):
self.window = window
self.plots = plots
self.status_bar = window.statusBar()
self.x_label = QtWidgets.QLabel("x: ")
self.y_label = QtWidgets.QLabel("y: ")
self.status_bar.addPermanentWidget(self.x_label)
self.status_bar.addPermanentWidget(self.y_label)
self.mouse_position = {}
for (name,pl),labels in plots.items():
self.mouse_position[pl] = MousePosition(self, pl, labels)
def set_x(self, x, prefix='x'):
self.x_label.setText(f"{prefix}: {x:8.5g} ")
def set_y(self, y, prefix='y'):
self.y_label.setText(f"{prefix}: {y:8.5g} ")
Where *plots* is a dict with keys being (*name, plotItem*) and value a
string that I want to show for the x and y coordinates on the status bar.
At the moment *name *is not used and I may delete it.
Cheers,
