However they wont be added om frame untill you use the add() funtion in the program. Here each variable declared and initialised will be position on the frame accordingly. The coordinates in above given frame would go somewhat this way:

The width and height determines the size of button in frame. The X_coordinate and Y_coordinate positions the label or button on X-axis and Y-axis respactively. The setBounds functions allows us to position the varible in th frame.

Variable_tBounds(X_coordinate,Y_coordinate,WIDTH,HEIGHT) The coordinates in the functions must be accurate in order to display the panel/button at right position in frame.Īn inbuilt function helps us to do the job in program. While using awt in any program we have a major challenge of displaying the elemets in the frame in systematic order. Try removing the statement and see what happens. tEchoChar(‘*’) <<<< This statement would change the characters to * while typing on screen. Newuse = new Label (“New User? Register Here”) Header = new Label(“WELCOME TO LIBRARY MANAGEMENT SYSTEM LOGIN”) The text in the (“_”) determines the text messages displayed in frame.įra = new Frame (“~~WELCOME TO LIBRARY MANAGEMENT SYSTEM LOGIN~~”) The following variable initialisations are made in program. TextField uid, pass <<< Fields in which text will be entered. Panel p1 <<< Declares the panel in frame.īutton loginb, exit, register <<< Buttons used in login page IE. Label userid, header, password, newuse, space1, space2 <<< Labels in program which would design the page and even set titles for page. The program code will have only one class, constructor, one function to launch frame and main function. Here we will be importing some library functions. We will be designing our LOGIN page today which would look this way. Today we will see how we are going to design our first page. I hope my last post cleared your mind regarding outline of the program.
