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_())
