1 We use the mobile phone from the screen to block down, and then pull out the interface we click on the "Control Center", and then click the picture shown in the "Screen rotation button", turn off the "vertical direction lock." (pictured below) 2 OK now we'll open the calculator on the Apple phone and see that it's not a science computer anymore, as shown in the following figure. (pictured below) 3 Now let's rotate the iphone6,iphone6 scr

Delphi7WidestringIt is implemented to store one character in two bytes. PcharIt is not the standard type of Pascal, but set to be compatible with the operating system and other languages,PcharDeclare a string pointer ending with a null character. More accurately, the character of this string isCharType, that isPcharPoint toCharString. 4. Structured construction type StructuredType can contain multiple elements or fields, so this type of variable can

Inheritance) In Object Pascal, one of the most powerful functions of a class is that it can be extended through inheritance. Inheritance)It refers to getting an existing class and adding functions by deriving a new class from it. The class for getting started is calledBase Class(Base class) orAncestor class(Ancestor class), the newly created class is calledDerived class(Derived class ). To illustrate these concepts, let's go backTairplaneClass. As we

Overwrite Method Let's first discuss the virtual method, or useTairplaneFor example, note thatTakeoffMethod inTairplaneClass is a virtual method (TakeoffMethod declaration endsVirtualKeyword ),TakeoffMethodSendmessageCall and respondMsgtakeoffMessage, if its derived classTmilitaryplaneClass does not provide its ownTakeoffMethod, base classTairplaneOfTakeoffThe method is called. BecauseTmilitaryplaneClass providesTakeoffMethod to callTmilitaryplaneClassTakeoffInstead of calling the method of the
