Now that we’ve added JComboBoxes, and Buttons to Create New and Save Data, lets work on loading data from our data source. We have our existing Student Data Access Class which we can use. Now we need to focus on getting a list of students, and displaying them. To do so, we’re going to start…
In our first examples of building a Form in Java, we looked at adding a button and using a simple event listener. Now we want to make a useful button with our Java GUI, ones that will load and save data, as well as one which will allow for creating new data. We’re going to…
Why we use Combo Boxes Combo boxes are a drop down menu option for forms. They allow us to limit the number of potential choices for a person to make, increasing the chance of a person picking a valid and correct option. In our example where we were extending a class for a Java GUI,…
In some cases we’re told what we need to know to rank in a search engine listing. But in many cases, changes and factors are applied without us knowing, which can be frustrating. In most cases, the search engines are trying to thwart “black hat” techniques, so they don’t necessarily want people to know they…
In our previous examples, we built the GUI from within the main method, and then built the GUI into an external class. We said that was beneficial in case we wanted to extend a class, like we will here. While this will create some extra work on the front end, it will make things easier…
In our previous example, we set up the GUI Frame inside of the main function. However, we want to move it to a different class so that we can separate out the logic of application from the interface. This will allow multiple people to work on different parts of the application easier, make it easier…
So our first example will be to build a simple GUI interface that launches from within the main. This isn’t a standard procedure, but is good to get a start into see how components work. Typically we’d have a separate class which would call and load the window. We’re going to start with a basic…
In early versions of Java, there was a GUI (Graphical User Interface) measure using AWT (Abstract Windowing Toolkit). However, it was quickly replaced with Swing, part of the JFC (Java Foundation Classes) for a couple of reasons. Java Foundation Classes (JFC) are a set of GUI components which simplify the development of desktop applications. Java…
