qlabel怎么设置文本换行对齐

调用QLabel的成员函数setAlignment ( Qt::Alignment )，举例：

QLabel * label = new QLabel("Hello!")

label->setAlignment(Qt::AlignRight | Qt::AlignBottom)

Qt::Aligment列表如下：

The horizontal flags are:

Constant Value Description

Qt::AlignLeft 0x0001 Aligns with the left edge.

Qt::AlignRight 0x0002 Aligns with the right edge.

Qt::AlignHCenter 0x0004 Centers horizontally in the available space.

Qt::AlignJustify 0x0008 Justifies the text in the available space.

The vertical flags are:

Constant Value Description

Qt::AlignTop 0x0020 Aligns with the top.

Qt::AlignBottom 0x0040 Aligns with the bottom.

Qt::AlignVCenter 0x0080 Centers vertically in the available space.

You can use only one of the horizontal flags at a time. There is one two-dimensional flag:

Constant Value Description

Qt::AlignCenter AlignVCenter | AlignHCenter Centers in both dimensions.

void MainWindow::createStatusBar()

{

locationLabel = new QLabel(" W999 ")//以文字" W999 " 建立 一个新的QLabel的对象

locationLabel->setAlignment(Qt::AlignHCenter)//文字对齐方式为中间对齐

locationLabel->setMinimumSize(locationLabel->sizeHint())

//设置这个Label的最小大小为当前最适合的大小。即Label的最小面积就是现在的大小了

formulaLabel = new QLabel

formulaLabel->setIndent(3)

//设置自动缩进

statusBar()->addWidget(locationLabel)

statusBar()->addWidget(formulaLabel, 1)

//第二个参数是设置 窗体 伸张系数的，默认为0.

connect(spreadsheet, SIGNAL(currentCellChanged(int, int, int, int)),

this, SLOT(updateStatusBar()))

connect(spreadsheet, SIGNAL(modified()),

this, SLOT(spreadsheetModified()))

updateStatusBar()

}
