示例1: MapObject
# 需要導入模塊: from PyQt5.QtGui import QPolygonF [as 別名]
# 或者: from PyQt5.QtGui.QPolygonF import isEmpty [as 別名]
#.........這裏部分代碼省略.........
##
def setPolygon(self, polygon):
self.mPolygon = polygon
##
# Returns the polygon associated with this object. Returns an empty
# polygon when no polygon is associated with this object.
##
def polygon(self):
return QPolygonF(self.mPolygon)
##
# Sets the shape of the object.
##
def setShape(self, shape):
self.mShape = shape
##
# Returns the shape of the object.
##
def shape(self):
return self.mShape
##
# Shortcut to getting a QRectF from position() and size().
##
def bounds(self):
return QRectF(self.mPos, self.mSize)
##
# Shortcut to getting a QRectF from position() and size() that uses cell tile if present.
##
def boundsUseTile(self):
if (self.mCell.isEmpty()):
# No tile so just use regular bounds
return self.bounds()
# Using the tile for determing boundary
# Note the position given is the bottom-left corner so correct for that
return QRectF(QPointF(self.mPos.x(),
self.mPos.y() - self.mCell.tile.height()),
self.mCell.tile.size())
##
# Sets the tile that is associated with this object. The object will
# display as the tile image.
#
# \warning The object shape is ignored for tile objects!
##
def setCell(self, cell):
self.mCell = cell
##
# Returns the tile associated with this object.
##
def cell(self):
return self.mCell
##
# Returns the object group this object belongs to.
##
def objectGroup(self):
return self.mObjectGroup
##
# Sets the object group this object belongs to. Should only be called
