I went with something similair.
self.label_a = pg.TextItem("[A]", color=(255, 255, 255))
self.label_a.setAnchor((0, 1))
self.label_a.setParentItem(line_segmet_roi)
self.label_a.setPos(x0, y0)
self.label_b = pg.TextItem("[B]", color=(255, 255, 255))
self.label_b.setAnchor((0, 0))
self.label_a.setParentItem(line_segmet_roi)
self.label_b.setPos(x1, y1)
def update_point_label_positions(self):
point1 = self.line_segment_roi["ROI"].getSceneHandlePositions(0)
_, scene_coords = point1
coords_a = self.line_segment_roi["ROI"].mapSceneToParent(scene_coords)
point2 = self.line_segment_roi["ROI"].getSceneHandlePositions(1)
_, scene_coords = point2
coords_b = self.line_segment_roi["ROI"].mapSceneToParent(scene_coords)
self.label_a.setPos(coords_a.x(), coords_a.y())
self.label_b.setPos(coords_b.x(), coords_b.y())
Thx for your reply. Luka.
