PySide.QtCore.QMetaEnum class provides meta-data about an enumerator.
使用 PySide.QtCore.QMetaEnum.name() for the enumerator's name. The enumerator's keys (names of each enumerated item) are returned by PySide.QtCore.QMetaEnum.key() ; use PySide.QtCore.QMetaEnum.keyCount() to find the number of keys. PySide.QtCore.QMetaEnum.isFlag() returns whether the enumerator is meant to be used as a flag, meaning that its values can be combined using the OR operator.
The conversion functions PySide.QtCore.QMetaEnum.keyToValue() , PySide.QtCore.QMetaEnum.valueToKey() , PySide.QtCore.QMetaEnum.keysToValue() ，和 PySide.QtCore.QMetaEnum.valueToKeys() allow conversion between the integer representation of an enumeration or set value and its literal representation. The PySide.QtCore.QMetaEnum.scope() function returns the class scope this enumerator was declared in.
| 参数： | QMetaEnum – PySide.QtCore.QMetaEnum |
|---|
| 返回类型： | PySide.QtCore.bool |
|---|
Returns true if this enumerator is used as a flag; otherwise returns false.
When used as flags, enumerators can be combined using the OR operator.
| 返回类型： | PySide.QtCore.bool |
|---|
Returns true if this enum is valid (has a name); otherwise returns false.
| 参数： | index – PySide.QtCore.int |
|---|---|
| 返回类型： | str |
Returns the key with the given index , or 0 if no such key exists.
| 返回类型： | PySide.QtCore.int |
|---|
返回键数。
| 参数： | key – str |
|---|---|
| 返回类型： | PySide.QtCore.int |
Returns the integer value of the given enumeration key , or -1 if key is not defined.
For flag types, use PySide.QtCore.QMetaEnum.keysToValue() .
| 参数： | keys – str |
|---|---|
| 返回类型： | PySide.QtCore.int |
Returns the value derived from combining together the values of the keys using the OR operator, or -1 if keys is not defined. Note that the strings in keys must be ‘|'-separated.
| 返回类型： | str |
|---|
Returns the name of the enumerator (without the scope).
例如， Qt.AlignmentFlag enumeration has AlignmentFlag as the name and Qt as the scope.
| 返回类型： | str |
|---|
Returns the scope this enumerator was declared in.
例如， Qt.AlignmentFlag enumeration has Qt as the scope and AlignmentFlag as the name.
| 参数： | index – PySide.QtCore.int |
|---|---|
| 返回类型： | PySide.QtCore.int |
Returns the value with the given index ; or returns -1 if there is no such value.
| 参数： | value – PySide.QtCore.int |
|---|---|
| 返回类型： | str |
Returns the string that is used as the name of the given enumeration value , or 0 if value is not defined.
For flag types, use PySide.QtCore.QMetaEnum.valueToKeys() .
| 参数： | value – PySide.QtCore.int |
|---|---|
| 返回类型： | PySide.QtCore.QByteArray |
Returns a byte array of ‘|'-separated keys that represents the given value .
