PyQt5 QTextBrowser - setText - 对齐问题? [英] PyQt5 QTextBrowser - setText - Alignment issue?

问题描述

我正在尝试使用 PyQt5 制作一个简单的 GUI 控制台.在尝试使用 QTextBrowser - setText 打印文本时，它会失去对齐并且看起来很糟糕.但文本在我的 python 控制台中对齐

我正在使用 setText 函数来显示我的数据框.更改 df.to_string() 的 justify 参数后，我可以在 python 控制台中看到更改的对齐方式，但这并未反映在我的 Qt 控制台中.

代码:

导入系统从 GUI_4 导入 Ui_MainWindow从 PyQt5 导入 QtCore、QtGui、QtWidgets导入 New_Read_Map_File定义窗口():app = QtWidgets.QApplication(sys.argv)MainWindow = QtWidgets.QWidget()标签 = QtWidgets.QTextBrowser(MainWindow)label.setStyleSheet('颜色:蓝色')MainWindow.setGeometry(600,150,800,800)label.setGeometry(10,10,780,780)获取数据()label.setText(DisplayData)MainWindow.show()sys.exit(app.exec_())定义获取数据():全局显示数据New_Read_Map_File.read_MapFile_main()DisplayData = (New_Read_Map_File.df.to_string(col_space = 14,justify = "justify"))打印(显示数据)窗户()

解决方案

问题是字体引起的，在控制台和很多IDES使用

I am trying to make a simple GUI console using PyQt5. On trying to print the text using QTextBrowser - setText, it loses alignment and looks bad. but the text is aligned in my python console

I am using the setText function to display my data frame. On changing the justify parameter of df.to_string(), i am able to see the changed alignment in the python console, but this is not reflected in my Qt console.

Code :

import sys
from GUI_4 import Ui_MainWindow
from PyQt5 import QtCore, QtGui, QtWidgets
import New_Read_Map_File

def window():    
    app = QtWidgets.QApplication(sys.argv)
    MainWindow = QtWidgets.QWidget()   
    label = QtWidgets.QTextBrowser(MainWindow)                    
    label.setStyleSheet('color: blue')    
    MainWindow.setGeometry(600,150,800,800)
    label.setGeometry(10,10,780,780)    
    GetData()
    label.setText(DisplayData)
    MainWindow.show()
    sys.exit(app.exec_())    

def GetData():
    global DisplayData
    New_Read_Map_File.read_MapFile_main()
    DisplayData = (New_Read_Map_File.df.to_string(col_space = 14,justify = "justify"))    
    print(DisplayData)


window()

Expected Alignment

解决方案

The problem is caused by the font, in the case of consoles and many IDES use a monospaced font.

For example, if you use the Monospace font:

import numpy as np
import pandas as pd
from PyQt5 import QtCore, QtGui, QtWidgets

def pandas_to_str():
    df = pd.DataFrame({ 
        'A' : 1.,
        'B' : pd.Timestamp('20130102'),
        'C' : pd.Series(1,index=list(range(4)),dtype='float32'),
        'D' : np.array([3] * 4,dtype='int32'),
        'E' : pd.Categorical(["test","train","test","train"]),
        'F' : 'foo' })
    return df.to_string(col_space =14,justify = "justify")

if __name__ == '__main__':
    import sys

    app = QtWidgets.QApplication(sys.argv)
    w = QtWidgets.QTextBrowser()
    w.setStyleSheet('color: blue') 
    w.setFont(QtGui.QFont("Monospace"))
    w.setWordWrapMode(QtGui.QTextOption.NoWrap)
    w.setText(pandas_to_str())
    w.showMaximized()
    sys.exit(app.exec_())
