python 中pyqt5 树节点点击实现多窗口切换问题

下面通过实例代码给大家介绍python 中pyqt5 树节点点击实现多窗口切换问题，具体代码如下所示：

# coding=utf-8
import sys
from PyQt5.QtWidgets import *
from PyQt5.QtCore import *
from PyQt5.QtGui import *
class Example(QWidget):
def __init__(self):
 super().__init__()
 self.initUI()
def initUI(self):
 hbox = QHBoxLayout(self)
 left = QFrame(self)
 # QFrame 控件添加StyledPanel样式能使QFrame 控件之间的界限更加明显
 #left.setFrameShape(QFrame.StyledPanel)
 right = QFrame(self)
 #right.setFrameShape(QFrame.StyledPanel)
 splitter1 = QSplitter(Qt.Horizontal)
 splitter1.addWidget(left)
 splitter1.setSizes([20,]) #设置分隔条位置
 splitter1.addWidget(right)
 hbox.addWidget(splitter1)
 self.setLayout(hbox)
 # 树
 self.tree = QTreeWidget(left)
 self.tree.setStyleSheet("background-color:#eeeeee;border:outset;color:#215b63;")
 self.tree.setAutoScroll(True)
 self.tree.setEditTriggers(QAbstractItemView.DoubleClicked | QAbstractItemView.EditKeyPressed)
 self.tree.setTextElideMode(Qt.ElideMiddle)
 #self.tree.setIndentation(30)
 self.tree.setRootIsDecorated(True)
 self.tree.setUniformRowHeights(False)
 self.tree.setItemsExpandable(True)
 self.tree.setAnimated(False)
 self.tree.setHeaderHidden(True)
 self.tree.setExpandsOnDoubleClick(True)
 self.tree.setObjectName("tree")
 # 设置根节点
 root = QTreeWidgetItem(self.tree)
 root.setText(0, '系统管理')
 # 设置树形控件的列的宽度
 #self.tree.setColumnWidth(0, 150)
 # 设置子节点1
 child1 = QTreeWidgetItem()
 child1.setText(0, '增加人员信息')
 root.addChild(child1)
 # 设置子节点2
 child2 = QTreeWidgetItem(root)
 child2.setText(0, '查询人员信息')
 # 加载根节点的所有属性与子控件
 self.tree.addTopLevelItem(root)
 # 设置stackedWidget
 self.stackedWidget = QStackedWidget(right)
 # 设置第一个面板
 self.form1 = QWidget()
 self.formLayout1 = QHBoxLayout(self.form1)
 self.label1 = QLabel()
 self.label1.setText("增加人员信息面板")
 self.label1.setSizePolicy(QSizePolicy(QSizePolicy.Expanding, QSizePolicy.Expanding))
 self.label1.setAlignment(Qt.AlignCenter)
 self.label1.setFont(QFont("Roman times", 50, QFont.Bold))
 self.formLayout1.addWidget(self.label1)
 # 设置第二个面板
 self.form2 = QWidget()
 self.formLayout2 = QHBoxLayout(self.form2)
 self.label2 = QLabel()
 self.label2.setText("查询人员信息面板")
 self.label2.setSizePolicy(QSizePolicy(QSizePolicy.Expanding, QSizePolicy.Expanding))
 self.label2.setAlignment(Qt.AlignCenter)
 self.label2.setFont(QFont("Roman times", 50, QFont.Bold))
 self.formLayout2.addWidget(self.label2)
 # 将两个面板，加入stackedWidget
 self.stackedWidget.addWidget(self.form1)
 self.stackedWidget.addWidget(self.form2)
 # 树节点监听事件
 self.tree.clicked.connect(self.onClicked)
 # 窗口最大化
 self.showMaximized()
 self.setWindowTitle('树窗口分隔案列')
 self.show()
def onClicked(self,qmodeLindex):
 item=self.tree.currentItem()
 print('Key=％s,value=％s'％(item.text(0),item.text(1)))
 if item.text(0) == '增加人员信息':
  self.on_pushButton1_clicked()
 elif item.text(0) == '查询人员信息':
  self.on_pushButton2_clicked()
 else:
  print('返回主界面')
# 按钮一：打开第一个面板
def on_pushButton1_clicked(self):
 self.stackedWidget.setCurrentIndex(0)
# 按钮二：打开第二个面板
def on_pushButton2_clicked(self):
 self.stackedWidget.setCurrentIndex(1)
if __name__ == '__main__':
app = QApplication(sys.argv)
ex = Example()
sys.exit(app.exec_())

ps：下面给大家介绍下python pyqt5 点击按钮来打开另一个窗口

import ui_denglu as dl
import ui_zhuche as zc
from PyQt5.QtWidgets import QApplication,QMainWindow,QDialog
import sys
class parentWindow(QMainWindow):
def __init__(self):
 QMainWindow.__init__(self)
 self.main_ui = dl.Ui_submit_user()
 self.main_ui.setupUi(self)
class childWindow(QDialog):
def __init__(self):
 QDialog.__init__(self)
 self.child=zc.Ui_MainWindow()
 self.child.setupUi(self)
if __name__=='__main__':
app=QApplication(sys.argv)
window=parentWindow()
child=childWindow()
#通过toolButton将两个窗体关联
btn=window.main_ui.pushButton_new
btn.clicked.connect(child.show)
# 显示
window.show()
sys.exit(app.exec_())
