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 ak
from PyQt5 import QtCore
from PyQt5.QtCore import pyqtSignal
from pandas import DataFrame
class 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：
