如何将文本与 QTableWidget 中的单元格中心对齐

How to align the text to center of cells in a QTableWidget(如何将文本与 QTableWidget 中的单元格中心对齐)

问题描述

我使用的是基于 Qt4 的 PyQt.我的编辑器是 PyCharm 2017.3，我的 Python 版本是 3.4.我正在从网站上抓取一些文本.我正在尝试将该文本与 QTableWidget 中单元格的中心对齐.

item = QTableWidgetItem(scraped_age).setTextAlignment(Qt.AlignHCenter)self.tableWidget.setItem(x, 2,item)

因此，在将项目放入单元格时，我试图按照

当我删除 setTextAlignment 方法时确实出现了，如下所示

item = QTableWidgetItem(scraped_age)self.tableWidget.setItem(x, 2,item)

这行代码:

item = QTableWidgetItem(scraped_age).setTextAlignment(Qt.AlignHCenter)

将无法正常工作，因为它会在将其分配给变量之前丢弃它创建的项目.该变量实际上将设置为None，这是setTextAlignment() 的返回值.相反，您必须这样做:

item = QTableWidgetItem(scraped_age) # 创建项目item.setTextAlignment(Qt.AlignHCenter) # 改变对齐方式

I am using PyQt based on Qt4. My Editor is PyCharm 2017.3 and my python version is 3.4. I am scraping some text from a website. I am trying to align that text to the center of the cell in a QTableWidget.

item = QTableWidgetItem(scraped_age).setTextAlignment(Qt.AlignHCenter)
self.tableWidget.setItem(x, 2,item)

Therefore while putting the item in the cell, I am trying to align it as per the documentation. The problem is that the data is not showing up.

It did show up when I removed setTextAlignment method as shown below

item = QTableWidgetItem(scraped_age)
self.tableWidget.setItem(x, 2,item)

This line of code:

item = QTableWidgetItem(scraped_age).setTextAlignment(Qt.AlignHCenter)

will not work properly, because it throws away the item it creates before assigning it to the variable. The variable will in fact be set to None, which is the return value of setTextAlignment(). Instead, you must do this:

item = QTableWidgetItem(scraped_age) # create the item
item.setTextAlignment(Qt.AlignHCenter) # change the alignment
