我正在尝试使用PyQT来定位和显示自定义小部件。到目前为止,我有一个小部件和我的窗口。我已经成功地通过布局显示了小部件,但是我想在show()之前使用.move(x,y,)来定位我的小部件。到目前为止,我的代码如下:
import sys, random
from PyQt4 import QtGui, QtCore
# Robot Widget
class RobotLink(QtGui.QWidget):
def __init__(self, parent, x, y, width, height, fill):
super(RobotLink, self).__init__(parent)
self._x = x
self._y = y
self._width = width
self._height = height
self._fill = fill
self._rotation = 0
def paintEvent(self, e):
painter = QtGui.QPainter()
painter.begin(self)
self.drawLink(painter)
painter.end()
def drawLink(self, painter):
painter.setPen(QtGui.QColor(0, 0, 0))
painter.setBrush(self._fill)
painter.drawEllipse(self._x, self._y, self._width, self._height)
# Window
class Window(QtGui.QWidget):
# Default Constructor, sets up the window GUI
def __init__(self):
super(Window, self).__init__()
self.initUI()
def initUI(self):
self._link1 = RobotLink(self, 225, 400, 30, 150, QtCore.Qt.DiagCrossPattern)
self._link2 = RobotLink(self, 0, 320, 30, 100, QtCore.Qt.Dense5Pattern)
self._link3 = RobotLink(self, 225, 260, 30, 75, QtCore.Qt.Dense2Pattern)
self._link1.move(0, 0)
self._link1.show()
self.setGeometry(300, 300, 800, 600)
self.setWindowTitle("CSCE 452 - PaintBot")
def paintEvent(self, e):
super(Window, self).paintEvent(e)
painter = QtGui.QPainter()
painter.begin(self)
self.drawBoundingBoxes(painter)
painter.end()
# Draws the boxes that define the robots workspace and
# the control panel
def drawBoundingBoxes(self, painter):
color = QtGui.QColor(0, 0, 0)
color.setNamedColor("#cccccc")
painter.setPen(color)
# Draw the robot workspace
painter.setBrush(QtGui.QColor(255, 255, 255))
painter.drawRect(10, 10, 500, 578)
# Draw the control panel workspace
painter.setBrush(QtGui.QColor(150, 150, 150))
painter.drawRect(520, 10, 270, 578)
# Draws the slider 'base'
painter.setPen(QtGui.QColor(0, 0, 0))
painter.drawLine(100, 570, 400, 570)
def changeValue(self, value):
self.wid.emit(QtCore.SIGNAL("updateRobot(int)"), value)
self.wid.repaint()
# Setup the Window, and the Robot
app = QtGui.QApplication(sys.argv)
win = Window()
win.show()
app.exec_()
有什么办法可以在没有布局的情况下附加我的小部件,将其定位并在我的窗口内显示吗?
