如何使用其他按钮增加qframe.hline行分隔符的宽度和距离?

pyqt5 layout button qt python

我有一个很小的 QFrame.HLine 我靠在线上做 Separator in box layout :

但是我不知道如何增加它的尺寸,也就是说,使它们之间的间距变大。这是一张photoshop图片,显示了我正在做的事情:

我试着设置属性 setLineWidth 和 setMidLineWidth ,但不管我设置它们的值有多大,行不会变大。

下面是示例代码:

#! /usr/bin/env python

import sys

from PyQt5 import QtWidgets

from PyQt5.QtWidgets import QFrame
from PyQt5.QtWidgets import QWidget

from PyQt5.QtWidgets import QPushButton
from PyQt5.QtWidgets import QVBoxLayout
from PyQt5.QtWidgets import QGridLayout

def main():
    app = QtWidgets.QApplication( sys.argv )
    programWindow = ProgramWindow()

    programWindow.show()
    sys.exit( app.exec_() )

class ProgramWindow(QtWidgets.QMainWindow):

    def __init__(self):
        QtWidgets.QMainWindow.__init__( self )
        self.setup_main_window()
        self.create_input_text()
        self.set_window_layout()

    def setup_main_window(self):
        self.resize( 400, 300  )
        self.centralwidget = QWidget()
        self.setCentralWidget( self.centralwidget )

    def create_input_text(self):
        self.separatorLine = QFrame()
        self.separatorLine.setFrameShape( QFrame.HLine )
        self.separatorLine.setFrameShadow( QFrame.Raised )

        # self.separatorLine.setLineWidth( 150 )
        # self.separatorLine.setMidLineWidth( 150 )

        rect = self.separatorLine.frameRect()
        print( "frameShape: %s" % rect )
        print( "width: %s" % self.separatorLine.width() )
        print( "height: %s" % self.separatorLine.height() )

        self.redoButton = QPushButton( "Redo Operations" )
        self.calculate  = QPushButton( "Compute and Follow" )
        self.open       = QPushButton( "Open File" )
        self.save       = QPushButton( "Save File" )

        self.verticalGridLayout = QGridLayout()
        self.verticalGridLayout.addWidget( self.redoButton    , 1 , 0)
        self.verticalGridLayout.addWidget( self.calculate     , 2 , 0)
        self.verticalGridLayout.addWidget( self.separatorLine , 3 , 0)
        self.verticalGridLayout.addWidget( self.open          , 4 , 0)
        self.verticalGridLayout.addWidget( self.save          , 5 , 0)
        self.verticalGridLayout.setSpacing( 0 )
        self.verticalGridLayout.setAlignment(Qt.AlignTop)

        self.innerLayout = QHBoxLayout()
        self.innerLayout.addLayout( self.verticalGridLayout )

    def set_window_layout(self):
        main_vertical_layout = QVBoxLayout( self.centralwidget )
        main_vertical_layout.addLayout( self.innerLayout )

qgridlayout.setRowMinimumHeight(行,最小大小)

将行行的最小高度设置为最小化像素。
