def paintEvent(self, e): qp = QtGui.QPainter() qp.begin(self) self.DrawChessBoard(qp) self.Draw_Chess(qp) qp.end()
pyqt的画图机制是:
每次界面更新时,自动调用 paintEvet(self,e)函数,所以将绘图的地方重写与该函数内。首先获得画笔,然后在begin方法h和end方法之间,执行绘图方法。但是,这里有个问题,我每次界面更新都会调用该方法,但是我们并不是每次都想执行绘制的的东西。比如我这里有两个函数:绘制棋盘和绘制棋子。每次我都需要绘制棋盘,但是不是每次都需要绘制棋盘。怎么办呢?设置绘制开关。我设置一个变量,通过if 进入不同的绘制函数。
补充这两个绘制函数:
def DrawChessBoard(self,qp): qp.setPen(QtCore.Qt.black) spos = [0, 0] epos = [0, 0] i = 0 # 画横线 while i < 15: spos[0] = self.startpos[0] spos[1] = self.startpos[1] + self.linelen * i epos[0] = self.startpos[0] + self.linelen * 14 epos[1] = self.startpos[1] + self.linelen * i # print i, spos, ‘--->‘, epos #self.drawText(str(15 - i), spos[0] - 25, spos[1], 20) qp.drawText(spos[0] - 35, spos[1], QString(str(15-i))) qp.drawLine( spos[0], spos[1], epos[0], epos[1]) i += 1 i = 0 while i < 15: spos[0] = self.startpos[0] + self.linelen * i spos[1] = self.startpos[1] epos[0] = self.startpos[0] + self.linelen * i epos[1] = self.startpos[1] + self.linelen * 14 #self.drawText((self.ch[i]), epos[0], epos[1] + 20, 20) qp.drawText(epos[0], epos[1] + 30, QString(self.ch[i])) qp.drawLine(spos[0], spos[1], epos[0], epos[1]) i += 1
def Draw_Chess(self,qp): self.color=[QtCore.Qt.blue,QtCore.Qt.black,QtCore.Qt.white] self.putOneChess=False #print u‘画一个棋子在棋盘‘ for point in self.PlayArr: arr_i,arr_j,chessKind=point pos_x,pos_y=self.Arr_To_Pos(arr_i,arr_j) #反走样 qp.setRenderHint(QPainter.Antialiasing, True) #设置画笔颜色、宽度 #qp.setPen(QPen(QColor(0, 0, 0), 2)) #设置画刷颜色 qp.setBrush(self.color[chessKind]) # 绘制圆 qp.drawEllipse(QPointF(pos_x, pos_y),15, 15) if len(self.PlayArr)>0: point =self.PlayArr[-1] arr_i, arr_j, chessKind = point pos_x, pos_y = self.Arr_To_Pos(arr_i, arr_j) # 反走样 qp.setRenderHint(QPainter.Antialiasing, True) # 设置画笔颜色、宽度 # qp.setPen(QPen(QColor(0, 0, 0), 2)) # 设置画刷颜色 qp.setBrush(QtCore.Qt.red) # 绘制圆 qp.drawEllipse(QPointF(pos_x, pos_y), 5, 5) if len(self.virPlayArr)>0: for point in self.virPlayArr: arr_i, arr_j, chessKind = point pos_x, pos_y = self.Arr_To_Pos(arr_i, arr_j) # 反走样 qp.setRenderHint(QPainter.Antialiasing, True) # 设置画笔颜色、宽度 # qp.setPen(QPen(QColor(0, 0, 0), 2)) # 设置画刷颜色 qp.setBrush(QtCore.Qt.blue) # 绘制圆 qp.drawEllipse(QPointF(pos_x, pos_y), 15, 15)
