获取北向资金数据pyqt5构建北向资金界面获取北向资金数据
如果我们需要构建北向资金界面，首先也是需要获取到北向资金的交易数据。我们直接上代码：
import akshare as akfrom PyQt5 import QtCorefrom PyQt5.QtCore import pyqtSignalfrom pandas import DataFrameclass NchThread(QtCore.QThread):_signal = pyqtSignal(DataFrame)def __init__(self):super(NchThread, self).__init__()def run(self):df = ak.stock_em_hsgt_board_rank(symbol="北向资金增持行业板块排行", indicator="今日")self._signal.emit(df)
这里，获取网络数据同样也需要在线程中获取，并返回给界面。
pyqt5构建北向资金界面
同之前的龙虎榜数据一样，我们通过QTableWidget组件进行构建，代码与上篇类似，我们直接上代码：
class MyFrom(QMainWindow):# 北向资金def init_nch(self):self.nchGrid = QGridLayout()self.nchGrid.setSpacing(5)self.nchTab.setLayout(self.nchGrid)self.nchThread = NchThread()self.nchThread._signal.connect(self.nchThead_callbacklog)self.nchThread.start()def nchThead_callbacklog(self, df):ft = QFont()ft.setPointSize(10)ft.setBold(True)nchtableWidget = QTableWidget(len(df), 6)nchtableWidget.setHorizontalHeaderLabels(['名称', '最新涨跌幅', '北向资金今日持股-股票只数', "北向资金今日增持估计-市值", "今日增持最大股-市值", "今日减持最大股-市值"])nchtableWidget.setEditTriggers(QAbstractItemView.NoEditTriggers) # 不可编辑nchtableWidget.horizontalHeader().setSectionResizeMode(QHeaderView.Fixed) # 禁止拖拽nchtableWidget.setSelectionBehavior(QAbstractItemView.SelectRows) # 只能选中一行nchtableWidget.itemClicked.connect(self.tableWidget_connect)nchtableWidget.verticalHeader().setVisible(False)nchtableWidget.setShowGrid(False) # 不显示子线条nchtableWidget.setColumnWidth(0, 150) # 设置第一列宽nchtableWidget.setColumnWidth(1, 100) # 设置第二列宽nchtableWidget.setColumnWidth(2, 200) # 设置第三列宽nchtableWidget.setColumnWidth(3, 210) # 设置第三列宽nchtableWidget.setColumnWidth(4, 200) # 设置第三列宽nchtableWidget.setColumnWidth(5, 200) # 设置第三列宽for idx, row in df.iterrows():if float(row["最新涨跌幅"]) < 0:m_color = QColor(0, 255, 0)elif float(row["最新涨跌幅"]) > 0:m_color = QColor(255, 0, 0)else:m_color = QColor(255, 255, 255)newItem0 = QTableWidgetItem(str(row["名称"]))newItem0.setFont(ft)newItem0.setForeground(QBrush(m_color))newItem1 = QTableWidgetItem(str(row["最新涨跌幅"]))newItem1.setFont(ft)newItem1.setForeground(QBrush(m_color))newItem2 = QTableWidgetItem(str(row["北向资金今日持股-股票只数"]))newItem2.setFont(ft)newItem2.setForeground(QBrush(m_color))newItem3 = QTableWidgetItem(str(row["北向资金今日增持估计-市值"]))newItem3.setFont(ft)newItem3.setForeground(QBrush(m_color))newItem4 = QTableWidgetItem(str(row["今日增持最大股-市值"]))newItem4.setFont(ft)newItem4.setForeground(QBrush(m_color))newItem5 = QTableWidgetItem(str(row["今日减持最大股-市值"]))newItem5.setFont(ft)newItem5.setForeground(QBrush(m_color))newItem0.setTextAlignment(Qt.AlignHCenter | Qt.AlignVCenter)newItem1.setTextAlignment(Qt.AlignHCenter | Qt.AlignVCenter)newItem2.setTextAlignment(Qt.AlignHCenter | Qt.AlignVCenter)newItem3.setTextAlignment(Qt.AlignHCenter | Qt.AlignVCenter)newItem4.setTextAlignment(Qt.AlignHCenter | Qt.AlignVCenter)newItem5.setTextAlignment(Qt.AlignHCenter | Qt.AlignVCenter)nchtableWidget.setItem(idx, 0, newItem0)nchtableWidget.setItem(idx, 1, newItem1)nchtableWidget.setItem(idx, 2, newItem2)nchtableWidget.setItem(idx, 3, newItem3)nchtableWidget.setItem(idx, 4, newItem4)nchtableWidget.setItem(idx, 5, newItem5)self.nchGrid.addWidget(nchtableWidget, 0, 0, 16, 16)
运行之后，显示的效果如下图所示：
