人气:0

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_())
