Performance Evaluation Of Graphical User Interfaces In Java And C#


Once you’re familiar with Tk programming and basic GUI design, I recommend that you explore using wxPython. Be consistent and predictable about where you place things — for instance, users are familiar with navigational elements on top menu bars or left sidebars. Adding navigation in a right sidebar or on the bottom will only make the user experience more difficult. When designing GUI, one need to keep the objectives of the GUI in mind and to generally avoid needless complexity .One must avoid useless innovation and concentrate on improvements that enhance performance.

This strategy of using addActionListeners was described in the preceding chapter. This style gives rise to relatively compact programs that introductory students find easy to understand, but you could just as well use any of the other styles of event detection described in section 3.3. The format control methods at the end of Figure 4-4 turn out to be relatively important. In the absence of format control, the value of a DoubleField often displays so many digits that the number becomes unreadable.

Graphical User Interface: Key Terms

The setFormat and getFormat methods eliminate this problem by allowing you to specify the output format. The format itself is specified using a string as defined in the DecimalFormat class in java.text. The use of format codes is illustrated in the currency converter program shown in Figure 4-8 later in this chapter.

These parameters have the same interpretation as in other standard Java layout managers such as FlowLayout and BorderLayout. When the table is formatted, hgap pixels are left blank at the left and right edges and between each column; symmetrically, the layout manager leaves vgap blank pixels at the top and bottom edges and between each row.

  • Graphical User Interface or simply called “GUI” is a general term used in the software world.
  • Many futuristic imaginings of user interfaces rely heavily on object-oriented user interface style and especially object-oriented graphical user interface style.
  • It is the result of processed user input and usually the main interface for human-machine interaction.
  • The graphical user interface is presented on the computer screen.
  • A GUI represents an application that has a visual display for the user with easy to use controls.

Widgets are defined by subclassing existing widgets, which can be either standard Tk Widgets or other application-defined widgets. Their initialization method creates all the widgets within the frame and specifies their arrangement. Any GUI can be built up like the last example, by constructing it object by object and providing the packer options. The GUI objects have to be structured in some way, and the usual way is the definition of application-specific higher-level widgets. The example above, for example, would benefit from a “line of buttons” widget. For example, although the following covers the Tk GUI toolkit, which comes standard in the Python distribution, there are alternatives, such as wxPython.

Although these values are typically positive, the implementation supports negative gaps, in which cells overlap by the specified number of pixels. The most common application for negative gaps occurs in displaying bordered components, which is illustrated in the CalendarDemo program described in section 4.6.

The user interface uses a JComboBox to specify the currencies, thereby illustrating that the TableLayout strategy can be used with a wide range of Java interactors. The code for the TemperatureConverter example calls the addActionListeners method to designate the program as an action listener for all buttons within it.

What is GUI tool?

A graphical user interface builder (or GUI builder), also known as GUI designer, is a software development tool that simplifies the creation of GUIs by allowing the designer to arrange graphical control elements (often called widgets) using a drag-and-drop WYSIWYG editor.
