## Member Function Documentation

### `[virtual]` QDesignerDynamicPropertySheetExtension::~QDesignerDynamicPropertySheetExtension()

Destroys the dynamic property sheet extension.

### `[pure virtual]` int QDesignerDynamicPropertySheetExtension::addDynamicProperty(const QString &propertyName, const QVariant &value)

Adds a dynamic property named propertyName and sets its value to value. Returns the index of the property if it was added successfully; otherwise returns -1 to indicate failure.

### `[pure virtual]` bool QDesignerDynamicPropertySheetExtension::canAddDynamicProperty(const QString &propertyName) const

Returns true if propertyName is a valid, unique name for a dynamic property; otherwise returns false.

### `[pure virtual]` bool QDesignerDynamicPropertySheetExtension::dynamicPropertiesAllowed() const

Returns true if the widget supports dynamic properties; otherwise returns false.

### `[pure virtual]` bool QDesignerDynamicPropertySheetExtension::isDynamicProperty(int index) const

Returns true if the property at the given index is a dynamic property; otherwise returns false.

### `[pure virtual]` bool QDesignerDynamicPropertySheetExtension::removeDynamicProperty(int index)

Removes the dynamic property at the given index. Returns true if the operation succeeds; otherwise returns false.
