详细描述

QFormLayout is a convenience layout class that lays out its children in a two-column form. The left column consists of labels and the right column consists of "field" widgets (line editors, spin boxes, etc.).

Traditionally, such two-column form layouts were achieved using QGridLayout . QFormLayout is a higher-level alternative that provides the following advantages:

Adherence to the different platform's look and feel guidelines.
例如， macOS Aqua and KDE guidelines specify that the labels should be right-aligned, whereas Windows and GNOME applications normally use left-alignment.
Support for wrapping long rows.
For devices with small displays, QFormLayout can be set to wrap long rows , or even to wrap all rows .

Convenient API for creating label--field pairs.

addRow () 重载接受 QString 和 QWidget * creates a QLabel behind the scenes and automatically set up its buddy. We can then write code like this:

QFormLayout *formLayout = new QFormLayout;
formLayout->addRow(tr("&Name:"), nameLineEdit);
formLayout->addRow(tr("&Email:"), emailLineEdit);
formLayout->addRow(tr("&Age:"), ageSpinBox);
setLayout(formLayout);

Compare this with the following code, written using QGridLayout :

nameLabel = new QLabel(tr("&Name:"));
nameLabel->setBuddy(nameLineEdit);
emailLabel = new QLabel(tr("&Name:"));
emailLabel->setBuddy(emailLineEdit);
ageLabel = new QLabel(tr("&Name:"));
ageLabel->setBuddy(ageSpinBox);
QGridLayout *gridLayout = new QGridLayout;
gridLayout->addWidget(nameLabel, 0, 0);
gridLayout->addWidget(nameLineEdit, 0, 1);
gridLayout->addWidget(emailLabel, 1, 0);
gridLayout->addWidget(emailLineEdit, 1, 1);
gridLayout->addWidget(ageLabel, 2, 0);
gridLayout->addWidget(ageSpinBox, 2, 1);
setLayout(gridLayout);

The table below shows the default appearance in different styles.

QCommonStyle derived styles (except QPlastiqueStyle)	QMacStyle	QPlastiqueStyle	Qt Extended styles

Traditional style used for Windows, GNOME, and earlier versions of KDE. Labels are left aligned, and expanding fields grow to fill the available space. (This normally corresponds to what we would get using a two-column QGridLayout )。	Style based on the macOS Aqua guidelines. Labels are right-aligned, the fields don't grow beyond their size hint, and the form is horizontally centered.	Recommended style for KDE applications . Similar to MacStyle, except that the form is left-aligned and all fields grow to fill the available space.	Default style for Qt Extended styles. Labels are right-aligned, expanding fields grow to fill the available space, and row wrapping is enabled for long lines.

The form styles can be also be overridden individually by calling setLabelAlignment (), setFormAlignment (), setFieldGrowthPolicy ()，和 setRowWrapPolicy (). For example, to simulate the form layout appearance of QMacStyle on all platforms, but with left-aligned labels, you could write:

formLayout->setRowWrapPolicy(QFormLayout::DontWrapRows);
formLayout->setFieldGrowthPolicy(QFormLayout::FieldsStayAtSizeHint);
formLayout->setFormAlignment(Qt::AlignHCenter | Qt::AlignTop);
formLayout->setLabelAlignment(Qt::AlignLeft);

enum QFormLayout:: FieldGrowthPolicy

This enum specifies the different policies that can be used to control the way in which the form's fields grow.

常量	值	描述
`QFormLayout::FieldsStayAtSizeHint`	`0`	The fields never grow beyond their effective size hint . This is the default for QMacStyle.
`QFormLayout::ExpandingFieldsGrow`	`1`	Fields with an horizontal size policy of Expanding or MinimumExpanding will grow to fill the available space. The other fields will not grow beyond their effective size hint. This is the default policy for Plastique.
`QFormLayout::AllNonFixedFieldsGrow`	`2`	All fields with a size policy that allows them to grow will grow to fill the available space. This is the default policy for most styles.

另请参阅 fieldGrowthPolicy .

enum QFormLayout:: ItemRole

This enum specifies the types of widgets (or other layout items) that may appear in a row.

常量	值	描述
`QFormLayout::LabelRole`	`0`	A label widget.
`QFormLayout::FieldRole`	`1`	A field widget.
`QFormLayout::SpanningRole`	`2`	A widget that spans label and field columns.

另请参阅 itemAt () 和 getItemPosition ().

enum QFormLayout:: RowWrapPolicy

This enum specifies the different policies that can be used to control the way in which the form's rows wrap.

常量	值	描述
`QFormLayout::DontWrapRows`	`0`	Fields are always laid out next to their label. This is the default policy for all styles except Qt Extended styles.
`QFormLayout::WrapLongRows`	`1`	Labels are given enough horizontal space to fit the widest label, and the rest of the space is given to the fields. If the minimum size of a field pair is wider than the available space, the field is wrapped to the next line. This is the default policy for Qt Extended styles.
`QFormLayout::WrapAllRows`	`2`	Fields are always laid out below their label.

另请参阅 rowWrapPolicy .

fieldGrowthPolicy : FieldGrowthPolicy

This property holds the way in which the form's fields grow

The default value depends on the widget or application style. For QMacStyle, the default is FieldsStayAtSizeHint ; for QCommonStyle derived styles (like Plastique and Windows), the default is ExpandingFieldsGrow ; for Qt Extended styles, the default is AllNonFixedFieldsGrow .

If none of the fields can grow and the form is resized, extra space is distributed according to the current form alignment .
