collection of information that is shared between different instances of the same window or control in Windows. When you create a new control using the traditional Windows programming method, you define a new window class and register it in Windows. You can also create a new window class based on an existing window class. This is called inheriting from the window class. In traditional Windows programming, if you want to build a customized control, you have to do it in a dynamic-link library, lik

Object Inspector is to look at the attribute type to determine whether the property is an event, and all method pointer properties are treated as events and appear in the event page. ⑷ Invoke Event Generally, it is best to focus the call on the event. This means that a virtual method is created in the part to invoke the user's event-handli

languages are also discussed below, therefore, if you are familiar with the type definition mentioned above, you may wish to read it down and you will be interested in the content. Finally, I will demonstrate some Delphi examples and introduce some tools that can dynamically access type information. Subfield type The subinterface type defines the value range of a certain type (Subrange). You can define the subboundary type of the integer type, for ex
