- QSizePolicy ( Policy horizontal, Policy vertical, uchar horizontalStretch, uchar verticalStretch, bool dependent = false )
- Qt::Orientations expanding () const
- Policy horData () const
- uint horStretch () const
- bool mayGrowHorizontally () const
- bool mayGrowVertically () const
- bool mayShrinkHorizontally () const
- bool mayShrinkVertically () const
- void setHorData ( Policy policy )

- Policy verData () const
- uint verStretch () const

## Member Type Documentation

### enum QSizePolicy::ExpandData

Use the Qt::Orientations enum instead.

Constant | Value | Description
--- | --- | ---
`QSizePolicy::NoDirection` | `0x0` | Use 0 instead.
`QSizePolicy::Horizontally` | `0x1` | Use Qt::Horizontal instead.
`QSizePolicy::Vertically` | `0x2` | Use Qt::Vertical instead.
`QSizePolicy::BothDirections` | `0x3` | Use Qt::Horizontal | Qt::Vertical instead.

### typedef QSizePolicy::SizeType

Use the QSizePolicy::Policy enum instead.

## Member Function Documentation

### QSizePolicy::QSizePolicy ( Policy horizontal, Policy vertical, bool dependent )

Use the QSizePolicy() constructor and the setHeightForWidth() function instead.

For example, if you have code like

     QSizePolicy *policy = new QSizePolicy(horizontal, vertical, dependent);

you can rewrite it as

     QSizePolicy *policy = new QSizePolicy(horizontal, vertical);
     policy->setHeightForWidth(dependent);

### QSizePolicy::QSizePolicy ( Policy horizontal, Policy vertical, uchar horizontalStretch, uchar verticalStretch, bool dependent = false )

Use the QSizePolicy() constructor and call the setHorizontalStretch(), setVerticalStretch(), and setHeightForWidth() functions instead.

For example, if you have code like

     QSizePolicy *policy = new QSizePolicy(horizontal, vertical,
                                                              horizontalStretch, verticalStretch,
                                                              dependent);

you can rewrite it as

     QSizePolicy *policy = new QSizePolicy(horizontal, vertical);
     policy->setHorizontalStretch(horizontalStretch);
     policy->setVerticalStretch(verticalStretch);
     policy->setHeightForWidth(dependent);

### Qt::Orientations QSizePolicy::expanding () const

Use expandingDirections() instead.

### Policy QSizePolicy::horData () const

Use horizontalPolicy() instead.

See also setHorData().

### uint QSizePolicy::horStretch () const

Use horizontalStretch() instead.

See also setHorStretch().

### bool QSizePolicy::mayGrowHorizontally () const

Use the horizontalPolicy() function combined with the QSizePolicy::PolicyFlag enum instead.

For example, if you have code like

     bool policy = mayGrowHorizontally();

you can rewrite it as

     bool policy = horizontalPolicy() & QSizePolicy::GrowFlag;

### bool QSizePolicy::mayGrowVertically () const

Use the verticalPolicy() function combined with the QSizePolicy::PolicyFlag enum instead.

For example, if you have code like

     bool policy = mayGrowVertically();

you can rewrite it as

     bool policy = verticalPolicy() & QSizePolicy::GrowFlag;

### bool QSizePolicy::mayShrinkHorizontally () const

Use the horizontalPolicy() function combined with the QSizePolicy::PolicyFlag enum instead.

For example, if you have code like

     bool policy = mayShrinkHorizontally();

you can rewrite it as

     bool policy = horizontalPolicy() & QSizePolicy::ShrinkFlag;

### bool QSizePolicy::mayShrinkVertically () const

Use the verticalPolicy() function combined with the QSizePolicy::PolicyFlag enum instead.

For example, if you have code like

     bool policy = mayShrinkVertically();

you can rewrite it as

     bool policy = verticalPolicy() & QSizePolicy::ShrinkFlag;

### void QSizePolicy::setHorData ( Policy policy )

Use setHorizontalPolicy() instead.

See also horData().

### void QSizePolicy::setHorStretch ( uchar stretch )

Use setHorizontalStretch() instead.

See also horStretch().

### void QSizePolicy::setVerData ( Policy policy )

Use setVerticalPolicy() instead.

See also verData().

### void QSizePolicy::setVerStretch ( uchar stretch )

Use setVerticalStretch() instead.

See also verStretch().

### Policy QSizePolicy::verData () const

Use verticalPolicy() instead.

See also setVerData().

### uint QSizePolicy::verStretch () const

Use verticalStretch() instead.

See also setVerStretch().
