c# - Custom editor resets list every frame -


i trying make reorderable list in unity storing list of custom classes:

using system; using unityengine;  [serializable] public struct onboardingitemdata {    [tooltip("the hint gameobject")]    public gameobject prefab;     [tooltip("the object hint highlighting")]    public gameobject target;  }

this class in list:

using system;     using system.collections.generic;     using unityengine;       public class onboardingitemlist : monobehaviour     {     public list<onboardingitemdata> list = new list<onboardingitemdata>();      private void update()     {         debug.log("list count: " + list.count);     }      public void refresh()     {         (int i=0; < list.count; i++)         {             if (list[i].prefab != null)             {                 list[i].prefab.getcomponent<onboardingitemclickhandler>().id =                  i;             }         }     }      public virtual void show(int id)     {         debug.log(list.count);         list[id].prefab.setactive(true);     }      public virtual void hide(int id)     {         list[id].prefab.setactive(false);     }     }

and list shown this:

using unityengine; using unityeditor; using unityeditorinternal;  [customeditor(typeof(onboardingitemlist))] public class onboardingeditor : editor { private reorderablelist list;  private void onenable() {     list = new reorderablelist(serializedobject,             serializedobject.findproperty("list"),             true, true, true, true);     list.drawelementcallback =         (rect rect, int index, bool isactive, bool isfocused) => {             var element =                        list.serializedproperty.getarrayelementatindex(index);             rect.y += 2;             editorgui.propertyfield(                 new rect(rect.x, rect.y, 200,                  editorguiutility.singlelineheight),                 element.findpropertyrelative("prefab"), guicontent.none);             editorgui.propertyfield(                 new rect(rect.x + 250, rect.y, 200,                  editorguiutility.singlelineheight),                 element.findpropertyrelative("target"), guicontent.none);         }; }  public override void oninspectorgui() {     list.dolayoutlist();     serializedobject.applymodifiedproperties();     onboardingitemlist myscript = (onboardingitemlist)target;     if (guilayout.button("apply"))     {         myscript.refresh();     } } }

now, in scene, there ui elements calling show() , hide() functions on onboardingitemlist. problem out of range exception, put debug.log in update() , see count of list changing. 1 frame says 2, next frame 0 , keeps changing , forth. assume keeps resetting list new one, , editor keeps assigning values of custom editor it. how fixed?

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
