Detailed Description

The QtEnumPropertyManager provides and manages enum properties.

\inmodule QtDesigner

Since
4.4

Each enum property has an associated list of enum names which can be retrieved using the enumNames() function, and set using the corresponding setEnumNames() function. An enum property's value is represented by an index in this list, and can be retrieved and set using the value() and setValue() slots respectively.

Each enum value can also have an associated icon. The mapping from values to icons can be set using the setEnumIcons() function and queried with the enumIcons() function.

In addition, QtEnumPropertyManager provides the valueChanged() signal which is emitted whenever a property created by this manager changes. The enumNamesChanged() or enumIconsChanged() signal is emitted whenever the list of enum names or icons is altered.

Member Function Documentation

◆ enumIcons()

QMap< int, QIcon > QtEnumPropertyManager::enumIcons ( const QtProperty * property) const

Returns the given property's map of enum values to their icons.

◆ enumIconsChanged

void QtEnumPropertyManager::enumIconsChanged ( QtProperty * property,
const QMap< int, QIcon > & icons )
signal

This signal is emitted whenever a property created by this manager changes its enum icons, passing a pointer to the property and the new mapping of values to icons as parameters.

See also
setEnumIcons()

◆ enumNames()

QStringList QtEnumPropertyManager::enumNames ( const QtProperty * property) const

Returns the given property's list of enum names.

See also
value(), setEnumNames()

Definition at line 4662 of file qtpropertymanager.cpp.

◆ enumNamesChanged

void QtEnumPropertyManager::enumNamesChanged ( QtProperty * property,
const QStringList & names )
signal

This signal is emitted whenever a property created by this manager changes its enum names, passing a pointer to the property and the new names as parameters.

setEnumNames()

◆ initializeProperty()

void QtEnumPropertyManager::initializeProperty ( QtProperty * property)
overrideprotectedvirtual

\reimp

Implements QtAbstractPropertyManager.

Definition at line 4807 of file qtpropertymanager.cpp.

◆ setEnumIcons

void QtEnumPropertyManager::setEnumIcons ( QtProperty * property,
const QMap< int, QIcon > & enumIcons )
slot

Sets the given property's map of enum values to their icons to enumIcons.

Each enum value can have associated icon. This association is represented with passed enumIcons map.

enumNames(), enumNamesChanged()

Definition at line 4791 of file qtpropertymanager.cpp.

◆ setEnumNames

void QtEnumPropertyManager::setEnumNames ( QtProperty * property,
const QStringList & enumNames )
slot

Sets the given property's list of enum names to enumNames.

The property's current value is reset to 0 indicating the first item of the list.

If the specified enumNames list is empty, the property's current value is set to -1.

See also
enumNames(), enumNamesChanged()

Definition at line 4757 of file qtpropertymanager.cpp.

◆ setValue

void QtEnumPropertyManager::setValue ( QtProperty * property,
int value )
slot

Sets the value of the given property to value.

The specified value must be less than the size of the given property's enumNames() list, and larger than (or equal to) 0.

◆ uninitializeProperty()

void QtEnumPropertyManager::uninitializeProperty ( QtProperty * property)
overrideprotectedvirtual

\reimp

Reimplemented from QtAbstractPropertyManager.

Definition at line 4815 of file qtpropertymanager.cpp.

◆ value()

int QtEnumPropertyManager::value ( const QtProperty * property) const

Returns the given property's value which is an index in the list returned by enumNames()

If the given property is not managed by this manager, this function returns -1.
