Qt 表的最后一列未拉伸以填充父级 [英] Qt table last column not stretching to fill in parent

问题描述

我正在尝试使用 QTableWidget(我也尝试了 QTableView)来制表一些数据.我预计最后一列会拉伸并填充父列，但事实并非如此.我在 Stackoverflow 上找到了几个答案，要求我执行以下操作:

I am trying to use a QTableWidget (I also tried a QTableView) to tabulate some data. I expected the last column to stretch and fill the parent, but it isn't. I found a couple of answer on Stackoverflow which asked me to do the following:

QTableWidget* table = new QTableWidget();
QHeaderView* headerView = new QHeaderView(Qt::Horizontal);
table->setWindowTitle(QString::fromUtf8("QTableWidget Header Stretch"));
table->setSizePolicy(QSizePolicy::Expanding,QSizePolicy::Expanding);
table->setColumnCount(2);
table->setRowCount(1);
//Set Header Label Texts Here
table->setHorizontalHeaderLabels(QString("HEADER 1;HEADER 2").split(";"));
table->setItem(0,0,new QTableWidgetItem("CELL 1"));
table->setItem(0,1,new QTableWidgetItem("CELL 2"));
headerView->sectionResizeMode(QHeaderView::Stretch);
//add the stretch here
headerView->stretchLastSection();
table->setHorizontalHeader(headerView);
table->show();

然而，它仍然没有拉伸到填充，如下图所示:

However, it is still not stretching to fill, as evident from the following picture:

知道我该怎么做吗?我想大多数答案都与 Qt 4 有关，我使用的是 Qt 5.

Any idea how do I do it? I guess most of the answers concerned Qt 4, I am using Qt 5.

推荐答案

您可能想要:

headerView->setStretchLastSection(true);
