The Popup control provides functionality that enables you to customize its behavior and appearance. For more information, see Expander Overview. If you want to create a control that displays a header with a collapsible area that displays content, use the Expander control. If you want to create a selection control that has a drop-down list box that can be shown or hidden, use the ComboBox control.Įxpander. For more information, see ContextMenu Overview.ĬomboBox. If you want to create a context menu for an element, use the ContextMenu control. For more information, see ToolTip Overview.ĬontextMenu. If you want to create a tooltip for an element, use the ToolTip and ToolTipService classes. The following controls implement the Popup control for specific uses: You can build Popup controls into other controls. The content of the Popup is displayed in a separate window that floats over the application window near the related ToggleButton control. Because a ToggleButton can have only one child element, this example places the text for the ToggleButton and the Popup controls in a StackPanel.

The following example shows how to define a Popup control that is the child element of a ToggleButton control. For more information, see ToolTip Overview.
If you want a Popup to automatically open, use the ToolTip or ToolTipService class. JButton.A Popup does not automatically open when the mouse pointer moves over its parent object. JLabel jLabel = new JLabel("Press close button to close the dialog.") To do that, we call the addActionListener() function that overrides the actionPerformed() method in which we specify the action to be performed.Īt last, we add all the components or objects that we created using jd.add(). Now, we have to set the action to perform when the close button is clicked. To enable the user to close the dialog, we create a JButton object with the text Close. We create a jLabel variable with the text message passed inside the constructor to show a text. To set the position and the size of the pop window, we use the setBounds() function, where the first two arguments are x and y positions, and the last two arguments are width and height. We set the FlowLayout() function that arranges the components in a line using jd.setLayout(). Now we need to set the layout of the dialog that specifies how to place the components inside the dialog. To create a frame, we need a jFrame object that is passed to the constructor of JDialog() as an argument when we create an object of JDialog and jd. In the second method, we use the Jdialog class. ("You pressed Cancel") Ĭreate Pop Up Window in Java Using JDialog
Int result = JOptionPane.showConfirmDialog(jFrame, "Press any button to close the dialog.") The showConfirmDialog() method returns an int that specifies the button that was clicked: 0 means Yes, 1 means No, and any other integer specifies that the cancel button was clicked. Just like the other methods, we pass a jFrame object and a message to show. JOptionPane.showMessageDialog(jFrame, "Your message: "+getMessage) Įxample 3: We use the JOptionPane.showConfirmDialog() function to show a dialog with three buttons: Yes, No, and Cancel. String getMessage = JOptionPane.showInputDialog(jFrame, "Enter your message") Here, to store the input, we use a String variable and then show it to the user using showMessageDialog(). JOptionPane.showMessageDialog(jFrame, "Hello there! How are you today?") Įxample 2: This example uses the JOptionPane.showInputDialog() function to show a message with an input field to get the input. The second argument is the message that we want to display in the dialog. The following are the examples of the methods:Įxample 1: Show a message inside a JFrame by creating a Jframe object, call the JOptionPane.showMessageDialog() method, and pass the first jFrame object as its first argument. Some of the common techniques are listed below: Method Description showMessageDialog() Displays a message inside a specified frame showInputDialog() Get input from the user in the popup window showConfirmDialog() Shows the message and asks the user for confirmation like yes, no, or cancel The simplest way to create a Java pop up window or a dialog is to use the JOptionPane class as part of the javax.swing package, which comes with many useful methods. Create Pop Up Window in Java Using JOptionPane
We will use two classes, JOptionPane and JDialog, in the following examples. In this tutorial, we’re going to look at the dialog and learn how to create it. Java allows us to create several types of GUI components using libraries like AWT, Swing and, JavaFX. Create Pop Up Window in Java Using JDialog.Create Pop Up Window in Java Using JOptionPane.
