qlabel怎么设置文本换行对齐

Answer 1

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.
