------------------------------------------------

------:::模块定义:::-----------
local UIBaseForm = {}

------:::模块内成员变量定义:::-----------
--设置__index为模块,
UIBaseForm.__index = UIBaseForm

--=======定义静态方法,用于绑定卸载LuaForm的操作========

--绑定
function UIBaseForm.BindCSForm(form, gobj)
	--把UIBaseForm设置为form的父类
	setmetatable(form, UIBaseForm);
	--获取UILuaForm的脚本
	local _csForm = UIUtils.FindLuaForm(gobj.transform)
	if _csForm == nil then
		_csForm = UIUtils.FindExtendLuaForm(gobj.transform)
	end
	form.CSForm = _csForm;
	form._ActiveSelf_ = _csForm.IsVisible;

	form._OnShowAfter_ = function(obj)
        if obj.OnShowAfter then
            obj:OnShowAfter();
        end
        form._ActiveSelf_ = true;
	end

	form._OnHideBefore_ = function(obj)
		obj:DestroyAllVFX()
		if obj.UISkinDic then
			obj.UISkinDic:Clear();
		end
		if obj.OnHideBefore then
			return not (obj:OnHideBefore() == false);
		end
		return true;
	end

	form._OnHideAfter_ = function(obj)
		if obj.OnHideAfter then
			obj:OnHideAfter();
		end
		form._ActiveSelf_ = false;
	end

	--绑定回调处理函数给CS的窗体
	--1.实例化窗体后,先注册事件
	_csForm.UIRegisterEvent = Utils.Handler(form.OnRegisterEvents, form);
	--2.然后再Load其他子预制
	if form.OnLoad then
		_csForm.UILoadEvent = Utils.Handler(form.OnLoad, form);
	end
	--3.判断是否为第一次显示
	if form.OnFirstShow then
		_csForm.UIFirstShowEvent = Utils.Handler(form.OnFirstShow, form);
	end
	--4.显示之前的回调
	if form.OnShowBefore then
		_csForm.UIShowBefore = Utils.Handler(form.OnShowBefore, form);
	end
	--打开动画开始
	if form.OnShowAnimStart then
		_csForm.UIShowAnimStart = Utils.Handler(form.OnShowAnimStart, form);
	end
	--打开动画结束（如果有动画则在OnShowAfter）
	if form.OnShowAnimFinish then
		_csForm.UIShowAnimFinish = Utils.Handler(form.OnShowAnimFinish, form);
	end
	--5.显示之后的回调
	_csForm.UIShowAfter = Utils.Handler(form._OnShowAfter_, form);

	--1.隐藏
	if form.OnTryHide then
		_csForm.UITryHideEvent = Utils.Handler(form.OnTryHide, form);
	end
	--2.隐藏之前的回调
	_csForm.UIHideBeforeEvent = Utils.Handler(form._OnHideBefore_, form);
	--关闭动画开始
	if form.OnHideAnimStart then
		_csForm.UIHideAnimStart = Utils.Handler(form.OnHideAnimStart, form);
	end
	--3.隐藏之后的回调（关闭动画已结束）
	_csForm.UIHideAfterEvent = Utils.Handler(form._OnHideAfter_, form);
	--4.注销事件
	if form.OnUnRegisterEvents then
		_csForm.UIUnRegisterEvent = Utils.Handler(form.OnUnRegisterEvents, form);
	end
	--5.卸载
	if form.OnUnload then
		_csForm.UIUnLoadEvent = Utils.Handler(form.OnUnload, form);
	end
	--关闭动画结束的回调
	if form.OnHideAnimFinish then
		_csForm.UIHideAnimFinish = Utils.Handler(form.OnHideAnimFinish, form);
	end

	--屏幕切换
	if form.OnScreenOrientationChanged then
		_csForm.UIScreenOrientationChanged = Utils.Handler(form.OnScreenOrientationChanged, form);
	end

	_csForm.UIFormDestroyEvent = function()
		local _formName = form._Name_;
		if form.OnFormDestroy ~= nil  then
			form:OnFormDestroy();
		end
		if GameCenter.UIFormManager ~= nil then
			 GameCenter.UIFormManager:DestroyForm(_formName);
		end
	end

	--窗体激活
	if form.OnFormActive then
		_csForm.UIFormOnActiveEvent = Utils.Handler(form.OnFormActive, form);
	end
end

--解绑定
function UIBaseForm.UnBindCSForm(form)
	local _csForm = form.CSForm
	_csForm:ClearAllEvent()
	_csForm:SetHasEverShowed(false)
end

--=======定义Lua端调用CSForm的一些函数封装========

--注册消息
function UIBaseForm:RegisterEvent(eid, func, caller)
	if eid == nil then
		Debug.LogError("UIBaseForm:RegisterEvent(eid=nil)");
		return;
	end
	if func == nil then
		Debug.LogError(string.format("UIBaseForm:RegisterEvent(eid=%s,func=nil)",tostring(eid)));
		return;
	end
	if self.CSForm ~= nil then
		if caller == nil then
			self.CSForm:RegisterEvent(eid, Utils.Handler(func,self));
		else
			self.CSForm:RegisterEvent(eid, Utils.Handler(func,caller));
		end
	else
		Debug.LogError("self.CSForm == nil");
	end
end

--设置Texture
function UIBaseForm:LoadTexture(uiTex,type,name,cbFunc,caller)
	if uiTex == nil or type == nil or name == nil or name == "" then 
		Debug.LogError("UIBaseForm:LoadTexture param is invalid!");
		return; 
	end
	if self.CSForm == nil then 
		Debug.LogError("self.CSForm == nil!");
		return;
	end
	if caller == nil then
		self.CSForm:LoadTexture(uiTex,type,name,cbFunc and Utils.Handler(cbFunc,self));
	else
		self.CSForm:LoadTexture(uiTex,type,name,cbFunc and Utils.Handler(cbFunc,caller));
	end
end


--由子类调用的打开窗体函数
function UIBaseForm:OnOpen(object,sender)
	if self.CSForm ~= nil then
		self.CSForm:OnOpen(object,sender);
	end
end

--由子类调用的关闭窗体函数
function UIBaseForm:OnClose(object,sender)
	if self.CSForm ~= nil then
		self.CSForm:OnClose(object,sender);
	end
end

--获取显示的参数
function UIBaseForm:GetShowParam()
	if self.CSForm ~= nil then
		return self.CSForm.ShowParamObj;
	end
	return nil;
end

--获取默认隐藏的参数
function UIBaseForm:GetHideParam()
	if self.CSForm ~= nil then
		return self.CSForm.HideParamObj;
	end
	return nil;
end

--创建特效(一个对象只能创建一个特效)
function UIBaseForm:CreateVFX(trans, id, modelTypeCode, OnFinishedCallBack, isNotSynRQ, layer)
	if not self.VFXDic then
		self.VFXDic = Dictionary:New();
	end
	if self.VFXDic:ContainsKey(trans) then
		self.VFXDic[trans]:OnPlay()
		return self.VFXDic[trans];
	end
	local _uiVfx = UIUtils.RequireUIVfxSkinCompoent(trans);
	self.VFXDic:Add(trans, _uiVfx);
	_uiVfx:OnCreateAndPlay(modelTypeCode or ModelTypeCode.UIVFX, id, layer or LayerUtils.AresUI, OnFinishedCallBack, not isNotSynRQ)
	return _uiVfx;
end

--删除特效
function UIBaseForm:DestroyVFX(trans)
	if self.VFXDic then
		if self.VFXDic:ContainsKey(trans) then
			self.VFXDic[trans]:OnDestory();
			self.VFXDic:Remove(trans)
		end
	end
end

--删除所有特效
function UIBaseForm:DestroyAllVFX()
	if self.VFXDic then
		local _keys = self.VFXDic:GetKeys();
		for i=1, #_keys do
			self.VFXDic[_keys[i]]:OnDestory();
		end
		self.VFXDic:Clear();
	end
end

--设置该窗体的层级 UIFormRegion.cs
-- NoticRegion = 1500000,     //显示提示,自动删除等处理,不用玩家操作的窗体  
-- TopRegion = 1000000,       //Top层,
-- MiddleRegion = 0,     //主要功能的窗体都在这个层次中
-- MainRegion = -1000000,      //主界面层
-- BottomRegion = -2000000,       //类似HUD在这个层次中,属于最低层次
function UIBaseForm:SetRegion(FormRegion)
	self.CSForm.UIRegion = FormRegion or UIFormRegion.MiddleRegion
end

return UIBaseForm
