Introduction A few more features of Windows Builder plugin Changing variables Copyright © 2015 – Curt Hill

Variables Windows Builder is like a large number of other GUI builders It generates poor names for things –These are only the component names If the component is not referenced in code, we do not care –Labels and buttons are often not referenced in code Fortunately we may do something about it Copyright © 2015 – Curt Hill

Variable Names It is always possible to have Eclipse do a replace all –This might confuse Windows Builder but a reparse is possible The better way is to use the property inspector to change the name The field is Variable Copyright © 2015 – Curt Hill

JTextField size The contents of a JTextField does not affect its size like a label or button Instead it has a columns property in the property inspector It also may be set with the setColumns method in the code Copyright © 2015 – Curt Hill

About Box The about button can be accomplished in a number of ways Here is one: –Create a JDialog that is a second file We add a new file to the project just like we did before Instead of a Windows Application (which is a JFrame we use a JDialog Then we have to fill in the JDialog and show it from the main window Copyright © 2015 – Curt Hill

Adding JDialog Copyright © 2015 – Curt Hill

About Box Again This is a little more complicated than I would like Here is the easier alternative On the web site there is a pre-made About dialog –It is HTML to facilitate copying Place this in your file –At the very end – after the last brace In the comment there is the mechanism for calling it Copyright © 2015 – Curt Hill

Finally The Event handler just copies in the call which is in comments: MyAbout a = new MyAbout(null, false, "The program purpose", "Your name", "year"); Then modifies it: MyAbout a = new MyAbout(null, false, “Convert years to seconds” “Curt Hill", “2015"); Copyright © 2015 – Curt Hill
