[constexpr] QKeyCombination:: QKeyCombination ( Qt::Key key = Qt::Key_unknown)

Constructs a QKeyCombination object that represents the key key and no modifiers.

另请参阅 key ().

[explicit constexpr] QKeyCombination:: QKeyCombination ( Qt::Modifiers modifiers , Qt::Key key = Qt::Key_unknown)

Constructs a QKeyCombination object that represents the combination of key 采用修饰符 modifiers .

另请参阅 key () 和 keyboardModifiers ().

[explicit constexpr] QKeyCombination:: QKeyCombination ( Qt::KeyboardModifiers modifiers , Qt::Key key = Qt::Key_unknown)

Constructs a QKeyCombination object that represents the combination of key 采用修饰符 modifiers .

另请参阅 key () 和 keyboardModifiers ().

[static constexpr] QKeyCombination QKeyCombination:: fromCombined ( int combined )

构造 QKeyCombination object by extracting the key and the modifiers out of combined , which must be the result of a bitwise OR between a value of type Qt::Key and value of type Qt::KeyboardModifiers . toCombined () can be used in order to produce valid values for combined .

另请参阅 toCombined ().

[constexpr] Qt::Key QKeyCombination:: key () const

返回表示的键通过此 QKeyCombination 对象。

另请参阅 keyboardModifiers ().

[constexpr] Qt::KeyboardModifiers QKeyCombination:: keyboardModifiers () const

返回表示的键盘修饰符通过此 QKeyCombination 对象。

另请参阅 key ().

[constexpr] int QKeyCombination:: toCombined () const

Returns an integer value obtained by applying a bitwise OR between the values of key () 和 keyboardModifiers () represented by this object. A QKeyCombination object can be created from the returned integer value by using fromCombined ().

另请参阅 fromCombined (), key ()，和 keyboardModifiers ().
