Programming with WindowBuilder (english)
In our last part, we have a very simple application that
programs the conversion of the temperature in degrees Celsius to degrees
Fahrenheit and vice versa. As one or the other has already noticed, writing the
program by hand would be difficult and inaccurate. It would be inaccurate
because we cannot imagine this while programming in the thought while
programming it. Simply we would have to compile and test the program at each
step. In practice, of course, this would be extensive.
Since the developers of the Java programming language
have come up with a good solution and came to the decision to develop a tool
which should save the developer the work of programming a graphical application
by hand.
The purpose of this tool is that the user can simply draw
or construct his framework as in Blender or Adobe CS. The development
environment then produces the appropriate code. This means that we can easily
develop the shell of our program through the tool, but we must manually enter
the functions.
For example, in the application with the conversion of
temperature, you could, in which you have made the button Conversion, read the
entered number in the text area mathematical calculate and then return the
result of this conversion as a mathematical value.
In this part we will show you how to easily install the
above tool. Some of us already remembered from our previous post that we like
to use the Eclipse as a development environment. Of course you can use NetBeans
or IntelliJ, but this tutorial only works for Eclipse because this tool was
already preinstalled in the other development environments.
Step 1: Start Eclipse
Step 2: Chose your Workspace
Step 3: At the top of the
"Help" status bar, then "Install new software".
Step 4: Look up the term
"windowbuilder" on the internet
Step 5:
Step 6: Choose your Eclipse version
and go to its link. In our case, we have version 4.7.
Step 7: Copy this link
Step 8: Back to Eclipse. Insert the
link we have copied.
Step 9: Specify
the name of the install tool.
After tapping on Ok, you'll need to tap Ok again and then
restart Eclipse. Done you have the new tool installed.
In our next part, we will be practicing the first
experiences of Graphical Applications with the WindowBuilder.
For questions we are always available. ;)
