In the above example, a UI element called MainWindow is declared as a subclass of the built-in Window class. The XAML file defines the layout, which in this example is a vertical collection of controls - a textblock outlining instructions to the user, a textbox for the user to type their name, a button to submit, and a results text block.
Like in C and C++ there are functions that group reusable code. The main difference is that functions, just like in Java, have to reside inside of a class. A function is therefore called a method. A method has a return value, a name and usually some parameters initialized when it is called with some arguments.
A property, in some object-oriented programming languages, is a special sort of class member, intermediate in functionality between a field (or data member) and a method.The syntax for reading and writing of properties is like for fields, but property reads and writes are (usually) translated to 'getter' and 'setter' method calls.
This API is a part of .NET Framework 3.0. A Windows Forms application is an event-driven application supported by Microsoft's .NET Framework.Unlike a batch program, it spends most of its time simply waiting for the user to do something, such as fill in a text box or click a button.
C# has the modifiers public, protected,internal, private, protected internal, private protected, and file. [4] Java has public, package, protected, and private; package is the default, used if no other access modifier keyword is specified. The meaning of these modifiers may differ from one language to another.
Role information is based on the type of UI control with which a developer wants to interact. For example, if a developer is implementing a button that is clickable, the developer would select Pushbutton as the Role to implement. The following table shows an example list of MSAA Roles and their related descriptions.
A semi-transparent background can be made less intrusive by having the whole background area function as a close button: this is standard on most mobile operating systems, avoids making the user feel trapped, and makes modal windows feel less like malicious pop-ups. Design should follow common practices in the platform the program is running on.
PHP defines the "magic methods" __getand__set for properties of objects. [9] In this example of a simple class representing a student with only the name stored, one can see the variable name is private, i.e. only visible from the Student class, and the "setter" and "getter" is public, namely the getName() and setName('name') methods.
