set size of jframe form

[OhioSteve]

I have an extremely simple question. I have created my first jframe form using the NetBeans IDE. When I run the form, it displays at the top of my monitor. It is only about one inch high. However, I can resize to more normal dimensions.

How can I set it to be 5 inches x 7 inches all the time??

I have looked at all of the properties and I suspect that I need to change "preferredSize". However, I can't change it in the GUI. Whenever I change the numbers, they just revert to the old settings.

Actually, I cannot edit MANY of my form's properties. They are disabled in the GUI. In the code view, they have a light blue background. This is incredibly frustrating!!

How do I allow myself to edit everything??

I don't know anything about NetBeans, but you can set the size of a JFrame in code using the JFrame.setSize(Dimension) or JFrame.setSize(int width, int height) methods.

Hi OhioSteve,

U can do it by setting a property called maximisedbounds in the other properties tab of a NetBeans editor. This takes four values X,Y,Width,Height. But u should provide values in terms of pixcell not in inches.

when U click on play button in NetBeans to run your application It will start at a corner even u specify the x,y co-ordinate, but when u click on maximize button of the frame it will behave as u have specified.

Ther is a work around for this problem. It is true that u can not modify the code in the method initcomponents(blue color area) but u can edit the area where u Instantiate the Frame. There can set the frame size. I will paste some code which shows how to set frame size.
