零散知识点
//菜单分隔符
Builder.AddMenuSeparator();
//子菜单
Builder.AddSubMenu(
LOCTEXT("OOO","JJJJ"),
LOCTEXT("CCCC","KKKK"),
FNewMenuDelegate::CreateRaw (this,&FMyToolModule::SubPullDownBar)
);
//图片Slate
Builder.AddWidget(
SNew(SImage),

);
//输入框
Builder.AddEditableText(
LOCTEXT("EditableText","EditableTextJK"),
LOCTEXT("EditableTextO","EditableTextJK1"),

);
//搜索
Builder.AddSearchWidget();
//子菜单自定义Widget(Slate)
Builder.AddWrapperSubMenu(

} 对世界大纲中的物体,右键进行一些操作
1.先绑定方法
{
{
auto& MenuButtonArray = LevelEditorModule.GetAllLevelViewportContextMenuExtenders();
MenuButtonArray.Add(FLevelEditorModule::FLevelViewportMenuExtender_SelectedActors::CreateRaw(this,&FMyToolModule::SelectCueAS));
MyDeleHandel = MenuButtonArray.Last().GetHandle();
}
}2.具体方法如下
TSharedRef<FExtender> FMyToolModule::SelectCueAS(const TSharedRef<FUICommandList> MyCommandList,
const TArray<AActor*> AllActor)
{
TSharedRef<FExtender> Extender = MakeShareable(new FExtender);
EdtorPrint(FString::Printf(TEXT("Actor Num = %d"),AllActor.Num()));
if (AllActor.Num()>0)
{
//获取Level
FLevelEditorModule& LevelEditorModule = FModuleManager::LoadModuleChecked<FLevelEditorModule>("LevelEditor");
TSharedPtr<FUICommandList>LevelCommand = LevelEditorModule.GetGlobalLevelEditorActions();
Extender->AddMenuExtension("ActorControl",EExtensionHook::After,LevelCommand,FMenuExtensionDelegate::CreateRaw(this,&FMyToolModule::AddSelectButton));
}
return Extender;
}3.绑定样式,样式如下
//Actor选择扩展
void FMyToolModule::AddSelectButton(FMenuBuilder& Builder)
{
Builder.AddMenuEntry(FMyToolCommands::Get().PluginAction);
//菜单分隔符
Builder.AddMenuSeparator();
Builder.AddSubMenu(
LOCTEXT("OK_ONE", "just a task"),
LOCTEXT("OK_TWO", "just a task button"),
FNewMenuDelegate::CreateRaw(this,&FMyToolModule::SubPullDownBar)
);
} 对文件栏中文件右键进行一些操作
方法与上面类似
1.先绑定方法
{
FContentBrowserModule& ContentBrowserModule = FModuleManager::LoadModuleChecked<FContentBrowserModule>("ContentBrowser");
auto& Cont = ContentBrowserModule.GetAllPathViewContextMenuExtenders();
Cont.Add(FContentBrowserMenuExtender_SelectedPaths::CreateRaw(this,&FMyToolModule::GetPathFromEditor));
//此处需要换成FContentBrowserModule并且需要在build中添加该模块
//"ContentBrowser"
}2.具体方法实现
TSharedRef<FExtender> FMyToolModule::GetPathFromEditor(const TArray<FString>& NewPath)
{
TSharedRef<FExtender> Extender = MakeShareable(new FExtender);
EdtorPrint(FString::Printf(TEXT("Actor Num = %d"),NewPath.Num()));
if (NewPath.Num()>0)
{
//获取Level
FContentBrowserModule& BrowserModule = FModuleManager::LoadModuleChecked<FContentBrowserModule>("ContentBrowser");
Extender->AddMenuExtension("NewFolder",EExtensionHook::After,PluginCommands,FMenuExtensionDelegate::CreateRaw(this,&FMyToolModule::AddSelectButton));
}
for (auto xx : NewPath)
{
EdtorPrint(xx);
}
return Extender;
}绑定样式同上,不赘述
添加一个Actor detail面板属性
1.添加一个模块
"PropertyEditor"
2.创建一个自定义类xxx.h
.h
class FMyTestDetailCustom : public IDetailCustomization
{
public:
FMyTestDetailCustom();
//负责映射到对象面板上
virtual void CustomizeDetails( IDetailLayoutBuilder& DetailBuilder ) override;
//实例化面板
static TSharedRef< IDetailCustomization > MakeInstance();
};
.cpp
#define LOCTEXT_NAMESPACE "MyTestDetailCustom"
void FMyTestDetailCustom::CustomizeDetails(IDetailLayoutBuilder& DetailBuilder)
{
IDetailCategoryBuilder& DetailCategoryBuilderIns = DetailBuilder.EditCategory(TEXT("CustomizeDetails"));
DetailCategoryBuilderIns.AddCustomRow(LOCTEXT("MM","Test")).WholeRowContent()
[
SNew(STextBlock)
.Text(LOCTEXT("QQ","Test"))
];
}
TSharedRef< IDetailCustomization > FMyTestDetailCustom::MakeInstance()
{
return MakeShareable(new FMyTestDetailCustom);
}3.添加对应映射
//在创建的插件的.h文件中,找到PropertyEditorModule.cpp中的两个方法抄过来;
void FPropertyEditorModule::RegisterCustomClassLayout( FName ClassName, FOnGetDetailCustomizationInstance DetailLayoutDelegate )
void FPropertyEditorModule::RegisterCustomPropertyTypeLayout( FName PropertyTypeName, FOnGetPropertyTypeCustomizationInstance PropertyTypeLayoutDelegate, TSharedPtr<IPropertyTypeIdentifier> Identifier)
//再定义自定义方法调用上面方法进行绑定
void RegisterPropertyTypeCustomizations();
void RegisterObjectCustomizations();
//具体写法:
void FTestDetailsModule::RegisterObjectCustomizations()
{
RegisterCustomClassLayout("CustomizeObject",FOnGetDetailCustomizationInstance::CreateStatic(&FMyTestDetailCustom::MakeInstance));
}
void FTestDetailsModule::RegisterCustomClassLayout(FName ClassName,
FOnGetDetailCustomizationInstance DetailLayoutDelegate)
{
check(ClassName!= NAME_None);
RegisteredClassNames.Add(ClassName);
FPropertyEditorModule& PropertyModule = FModuleManager::GetModuleChecked<FPropertyEditorModule>("PropertyEditor");
PropertyModule.RegisterCustomClassLayout(ClassName,DetailLayoutDelegate);
}
void FTestDetailsModule::RegisterCustomPropertyTypeLayout(FName PropertyTypeName,
FOnGetPropertyTypeCustomizationInstance PropertyTypeLayoutDelegate)
{
check(PropertyTypeName != NAME_None);
RegisteredPropertyTypes.Add(PropertyTypeName);
FPropertyEditorModule& PropertyModule = FModuleManager::GetModuleChecked<FPropertyEditorModule>("PropertyEditor");
PropertyModule.RegisterCustomPropertyTypeLayout(PropertyTypeName,PropertyTypeLayoutDelegate);
}
//绑定好了之后找到StartupModule()进行调用
//先获取实例,然后调用上面写好的方法,并更新映射
void FTestDetailsModule::StartupModule()
{
FPropertyEditorModule& PropertyModule = FModuleManager::GetModuleChecked<FPropertyEditorModule>("PropertyEditor");
RegisterPropertyTypeCustomizations();
RegisterObjectCustomizations();
PropertyModule.NotifyCustomizationModuleChanged();//更新映射
}
//因为绑定后你还得解绑,所以我们先创建两个变量来保存相关内容
.h:
private:
TSet< FName > RegisteredClassNames;
TSet< FName > RegisteredPropertyTypes;
.cpp
//解绑:
void FTestDetailsModule::ShutdownModule()
{
if (FModuleManager::Get().IsModuleLoaded("PropertyEditor"))
{
FPropertyEditorModule& PropertyModule = FModuleManager::GetModuleChecked<FPropertyEditorModule>("PropertyEditor");
for (auto It = RegisteredClassNames.CreateIterator();It;++It)
{
if (It->IsValid())
{
PropertyModule.UnregisterCustomClassLayout(*It);
}
}
for (auto It = RegisteredPropertyTypes.CreateIterator();It;++It)
{
if (It->IsValid())
{
PropertyModule.UnregisterCustomPropertyTypeLayout(*It);
}
}
}
}
//这样就完成了基础的映射到UObject 对象的处理
自定义映射变量
1.创建一个Struct结构体文件
USTRUCT(BlueprintType)
struct TESTDETAILS_API FStructVariable
{
GENERATED_USTRUCT_BODY()
};2.创建一个StructVariableDetail文件,继承并抄过来对应方法
struct TESTDETAILS_API FStructVariableDetail:public IPropertyTypeCustomization
{
public:
virtual void CustomizeHeader( TSharedRef<IPropertyHandle> PropertyHandle, FDetailWidgetRow& HeaderRow, IPropertyTypeCustomizationUtils& CustomizationUtils )override;
virtual void CustomizeChildren( TSharedRef<IPropertyHandle> PropertyHandle, IDetailChildrenBuilder& ChildBuilder, IPropertyTypeCustomizationUtils& CustomizationUtils ) override;
//实例化面板
static TSharedRef< IPropertyTypeCustomization > MakeInstance();
};
.cpp具体方法实现
void FStructVariableDetail::CustomizeHeader(TSharedRef<IPropertyHandle> PropertyHandle, FDetailWidgetRow& HeaderRow,
IPropertyTypeCustomizationUtils& CustomizationUtils)
{
HeaderRow
.NameContent()
[
PropertyHandle->CreatePropertyNameWidget()
]
.ValueContent()
.MinDesiredWidth(125.0f)
.MaxDesiredWidth(325.0f)
[
SNew(SImage)
];
}
void FStructVariableDetail::CustomizeChildren(TSharedRef<IPropertyHandle> PropertyHandle,
IDetailChildrenBuilder& ChildBuilder, IPropertyTypeCustomizationUtils& CustomizationUtils)
{
}
TSharedRef<IPropertyTypeCustomization> FStructVariableDetail::MakeInstance()
{
return MakeShareable(new FStructVariableDetail);
}
3.最后映射到之前的方法中,也就是TestDetails.cpp文件中
void FTestDetailsModule::RegisterPropertyTypeCustomizations()
{
RegisterCustomPropertyTypeLayout("StructVariable",FOnGetPropertyTypeCustomizationInstance::CreateStatic(&FStructVariableDetail::MakeInstance));
}
