dateLabel = new JLabel('Select Date') ĭtFont(new Font('Times New Roman', Font.BOLD, 20)) The position of the JLabel object the x and y coordinates, height and width is set. This puts the upper left corner at location (x, y), where x the the number of pixels from the left of the screen and y is is the number from the top of the screen.height and width are as before. Public void setBounds(int x, int y, int width, int height) The setBounds() method not only specifies the size of the frame, but the location of the upper left corner: New JLabel object creation called “label” holding “SELECT DATE OF BIRTH” as text.įont style and size is set using. tFont(new Font('Times New Roman', Font.BOLD, 28)) label = new JLabel('SELECT DATE OF BIRTH') Background color is set to yellow using the getContentPane().setBackground() method.Īdd(panel) to add to the frame. GetContentPane().setBackground(Color.YELLOW) Īs in previous tutorials, the creation of a JPanel object. String month = Ī String “month” is declared and initiated to be passed to a Spinner object as argument. The tutorial uses an example to illustrate its functions and actions that can be associated with it.ĬODE BLOCK spinner Class import java.awt.* This is where this tutorial comes in handy.

You may use the same line of code to create objects of these constructs, but making them function requires different methods of coding. If you follow previous tutorials, you will notice these Swing Constructs are created the same way, however, their functionalities differ. This tutorial is done in assumption that the user follows through previous tutorials and is familiar with the coding terms used therein, also, have basic Java programming knowledge. In this tutorial, we will create two classes Ĭlass 1: We will create three JSpinner objects to simulate the user entering Date of Birth details First object, the user enters day, second object user enters month and third object user enters year.Ĭlass 2: Contains main method for run instructions. JSpinner(SpinnerModel model)Ĭonstructs a complete spinner with pair of next/previous buttons and an editor for the SpinnerModel.

Constructors in JSpinner JSpinner()Ĭonstructs a spinner with an Integer SpinnerNumberModel with initial value 0 and no minimum or maximum limits. The JSpinner's editor stays in sync with the model by listening for ChangeEvents. The editor is created by the JSpinner's constructor and can be changed with the editor property.

SpinnerModel classes for some common types are provided: SpinnerListModel,SpinnerNumberModel, and SpinnerDateModel.Ī JSpinner has a single child component that's responsible for displaying and potentially changing the current element or value of the model, which is called the editor. The model can be specified as a constructor argument and changed with the model property. Although combo boxes provide similar functionality, spinners are sometimes preferred because they don't require a drop down list that can obscure important data.Ī JSpinner's sequence value is defined by its SpinnerModel. The user may also be allowed to type a (legal) value directly into the spinner. The keyboard up/down arrow keys also cycle through the elements. Spinners typically provide a pair of tiny arrow buttons for stepping through the elements of the sequence. The tutorial introduce another interesting construct JSpinnerĪ single line input field that lets the user select a number or an object value from an ordered sequence. This tutorial follows from previous tutorials, on the topic of Swing constructs in GUI beginning with ‘J’.

An Integrated Development Environment(IDE) such as Eclipse or NetBeans is required to be installed on your computer.
