A dialog box is a component that allows users to communicate with the computer by entering inter-related data, responding to a question, or confirming their actions.
There are two kinds of dialog boxes: model and modeless.
A modal dialog box blocks interaction from the parent window which initiates the dialog while a modeless dialog does not. A good UI design should use a modeless dialog box as much as possible since it does not force users into a specific mode of operation.
In Java swing, there are several ways to create a dialog boxes:
- Simple dialog: for simple dialog boxes such as displaying confirmation, asking for simple data…etc you can use JOptionPane.
- Standard chooser: for standard choosers dialog boxes such as file chooser or color chooser you can use JFileChooser or JColorChooser.
- Complex data: For complex dialog, you can use JDialog class. Check out an example of creating a login dialog using JDialog class.
