如何对齐QHBoxLayout和QVBoxLayout的布局? [英] How to align the layouts QHBoxLayout and QVBoxLayout?
问题描述
我要为我的窗口进行以下布局:
I want to do this layout for my window:
所以我尝试创建一个QHBoxLayout
布局以放置3个按钮,并将其添加到QVBoxLayout
:
So I tried to create a QHBoxLayout
layout to put the 3 buttons, and add it to the QVBoxLayout
:
#!/usr/bin/python
# -*- coding: utf-8 -*-
import sys
from PyQt4 import QtGui
class Example(QtGui.QWidget):
def __init__(self):
super(Example, self).__init__()
self.initUI()
def initUI(self):
title = QtGui.QLabel( 'Title' )
author = QtGui.QLabel( 'Author' )
other = QtGui.QLabel( 'Other' )
titleEdit = QtGui.QLineEdit()
horizontalLayout = QtGui.QHBoxLayout( self )
horizontalLayout.addWidget( title )
horizontalLayout.addWidget( author )
horizontalLayout.addWidget( other )
verticalLayout = QtGui.QVBoxLayout( self )
verticalLayout.addWidget( titleEdit )
verticalLayout.addWidget( horizontalLayout )
self.setLayout( verticalLayout )
self.setGeometry( 300, 300, 350, 300 )
self.setWindowTitle( 'Review' )
self.show()
def main():
app = QtGui.QApplication( sys.argv )
ex = Example()
sys.exit( app.exec_() )
if __name__ == '__main__':
main()
但是它不接受其他布局:
But it is not accepting another layout:
verticalLayout.addWidget( horizontalLayout )
TypeError: addWidget(self, QWidget, stretch: int = 0, alignment: Qt.Alignment = 0): argument 1 has unexpected type 'QHBoxLayout'
如何进行此对齐?
使用addLayout()
通过@ GM 注释,我在控制台上收到了以下警告:
By @G.M. comment, using addLayout()
I got this warning on the console:
QLayout: Attempting to add QLayout "" to Example "", which already has a layout
QLayout::addChildLayout: layout "" already has a parent
QWidget::setLayout: Attempting to set QLayout "" on Example "", which already has a layout
但是现在显示的窗口没有编辑框:
But now the window was displayed without the edit box:
推荐答案
在更新中显示的问题是由于您必须以自己的父母身份而产生的,并将其放置在该小部件中,一个简单的解决方案是将其更改为:
The problem you show in your update is generated because you have to self as your parent, and this is placed in that widget, a simple solution is change to:
horizontalLayout = QtGui.QHBoxLayout()
完整代码:
class Example(QtGui.QWidget):
def __init__(self):
super(Example, self).__init__()
self.initUI()
def initUI(self)
title = QtGui.QLabel( 'Title' )
author = QtGui.QLabel( 'Author' )
other = QtGui.QLabel( 'Other' )
titleEdit = QtGui.QLineEdit()
horizontalLayout = QtGui.QHBoxLayout()
horizontalLayout.addWidget( title )
horizontalLayout.addWidget( author )
horizontalLayout.addWidget( other )
verticalLayout = QtGui.QVBoxLayout( self )
verticalLayout.addLayout( horizontalLayout )
verticalLayout.addWidget( titleEdit )
self.setLayout( verticalLayout )
self.setGeometry( 300, 300, 350, 300 )
self.setWindowTitle( 'Review' )
self.show()
def main():
app = QtGui.QApplication( sys.argv )
ex = Example()
sys.exit( app.exec_() )
另一个问题是您在谈论按钮,除了该图显示了几乎是正方形尺寸的小部件外,我认为如果要获取它,则应使用QTextEdit
.
Another question is that you talk about buttons, in addition that the graph shows a widget of almost square dimensions, I think if you want to get it you should use QTextEdit
.
完整代码:
#!/usr/bin/python
class Example(QtGui.QWidget):
def __init__(self):
super(Example, self).__init__()
self.initUI()
def initUI(self):
title = QtGui.QPushButton( 'Title' )
author = QtGui.QPushButton( 'Author' )
other = QtGui.QPushButton( 'Other' )
titleEdit = QtGui.QTextEdit()
horizontalLayout = QtGui.QHBoxLayout()
horizontalLayout.addWidget( title )
horizontalLayout.addWidget( author )
horizontalLayout.addWidget( other )
verticalLayout = QtGui.QVBoxLayout( self )
verticalLayout.addLayout( horizontalLayout )
verticalLayout.addWidget( titleEdit )
self.setLayout( verticalLayout )
self.setGeometry( 300, 300, 350, 300 )
self.setWindowTitle( 'Review' )
self.show()
def main():
app = QtGui.QApplication( sys.argv )
ex = Example()
sys.exit( app.exec_() )
if __name__ == '__main__':
main()
