用来验证InListItems的Object类型是否符合EntryWidgetClass的MVVM绑定的ViewModelProperty。
|
||
|
|
|
||
|
|
当前只在ListView里该函数使用。
|
||
|
|
|
||
|
|
## 原理：
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
UCLASS(meta = (EntryInterface = "/Script/UMG.UserObjectListEntry"), MinimalAPI)
|
||
|
|
class UListView : public UListViewBase, public ITypedUMGListView<UObject*>
|
||
|
|
{
|
||
|
|
UFUNCTION(BlueprintCallable, Category = ListView, meta = (AllowPrivateAccess = true, DisplayName = "Set List Items", ViewmodelBlueprintWidgetExtension = "EntryViewModel"))
|
||
|
|
UMG_API void BP_SetListItems(const TArray<UObject*>& InListItems);
|
||
|
|
}
|
||
|
|
|
||
|
|
void UMVVMViewBlueprintListViewBaseExtension::Precompile(UE::MVVM::Compiler::IMVVMBlueprintViewPrecompile* Compiler, UWidgetBlueprintGeneratedClass* Class)
|
||
|
|
{
|
||
|
|
}
|
||
|
|
```
