OnConnection method is the obvious point to place your UI (menus, mainbars, tool buttons) through which the user will communicate to the app. This method is also the place to put your validation code if you are licensing the add-in. You would normally do this before putting up the UI. If the user is not a valid user, you would not want to put the UI into the IDE.

  • param app : the object representing the current application in the IDE.
  • param connectMode : type of ConnectMode.

syntax 

function Map3DSystem.App.Inventory.OnConnection(app, connectMode)

parameters

app the object representing the current application in the IDE.
connectMode  

Map3DSystem.App.Inventory.OnDisconnection

Receives notification that the Add-in is being unloaded.

syntax 

function Map3DSystem.App.Inventory.OnDisconnection(app, disconnectMode)

parameters

app

Map3DSystem.App.Inventory.OnQueryStatus

This is called when the command's availability is updated When the user clicks a command (menu or mainbar button), the QueryStatus event is fired. The QueryStatus event returns the current status of the specified named command, whether it is enabled, disabled, or hidden in the CommandStatus parameter, which is passed to the msg by reference (or returned in the event handler).

  • param commandName : The name of the command to determine state for. Usually in the string format "Category.SubCate.Name".
  • param statusWanted : what status of the command is queried. it is of type CommandStatusWanted
  • return __ : returns according to statusWanted. it may return an integer by adding values in CommandStatus.

a bag contains stuffs of a person, a bag may contain other bags of the same person.

Title a bag contains stuffs of a person, a bag may contain other bags of the same person.
Author(s) LiXizhi, WangTian
Date 2008/1/16
File script/kids/3DMapSystemApp/Inventory/BagCtl.lua

Description

the bag concept is similar to folder in windows. We can exchange items between bags of the same persons, different persons, a shop and a person. We can also link a character with a given bag for the character to sell goods while the user is offline.

NOTE: implemented by WangTian, the bag control is a universal item container. The control displays in grid view and almost all the items allows drag and drop. According to develop note 2008/1/17, drag and drop between different bags works in different dragging behaviors.

TIP Sample Code
