このページは PropertyField
がサポートするデータ型変換とフィールドを説明します。
UI Toolkit のほとんどのビルトインコントロールは、特定のデータ型に対して INotifyValueChanged
インターフェースを実装しています。例えば、DoubleField
は INotifyValueChanged<Double>
を実装しています。つまり、 DoubleField
コントロールを double
型のプロパティにバインドできます。バインディングシステムを使えば、もっと多くのデータ型をバインドすることができます。例えば、int
型のプロパティを DoubleField
にバインドすることができます。
以下の表は、バインドできるソースと対象となるデータ型の一覧です。
ソースのデータ型 | INotifyValueChanged の対象データ型 |
---|---|
long |
|
int |
|
double |
|
float |
|
char |
|
ノート: データ損失を防ぐために、PropertyField
を使用するか、または以下の PropertyField がサポートするフィールドの表 に示す適切なデータ型を使用してください。
PropertyField
がサポートするフィールドWhen the Inspector window is populated, if a custom Editor does not exist for a type, the binding system calls InspectorElement.FillDefaultInspector()
. This creates a PropertyField
for each SerializedProperty
on the SerializedObject
.
Each PropertyField
has a matching control under it, such as an IntegerField
to represent an int
, or a Toggle
to represent a bool
. If the property has sub-properties, the PropertyField
has a Foldout
control. That Foldout
has the appropriate default controls under for each sub-property. If you created a custom PropertyDrawer
for a Property, the visual tree returned from the PropertyDrawer
’s CreatePropertyGUI()
method is used instead.
Note: When you create custom UI, don’t use a PropertyField
unless you can’t find a specific control for it. For example, to create a control in your visual tree and bind it to a Color
, use a ColorField
rather than a PropertyField
. This makes visual trees more lightweight and the operations faster.
