It is a fairly complex user interface screen with a number of different controls, and with different component regions. Our GridBagLayout has gridX and gridY constraints which can be associated with the components we have sketched in our grid. If we think about it for a while, we can see that not all regions fit into a grid cell, some regions spread into two cells marked in blue:. We can make the GridBagLayout make these two blue regions cover more than one cell using the gridWidth and gridHeight constraint.

The following code sets up the main components in the frame using GridBagLayout.

Notice how one GridBagConstraint object is being created and being passed in with the component to the main panel? This constraint object holds all the information on how a component should be displayed. In our first cut, we are only interested in the X and Y placement, and spans, so we set gridX and gridY on all the first level components we are adding.

For our button panel at the bottom we set the gridWidth to 2, indicating that we want it to spread to the right gridbaglyaout one more grid cell, and likewise with the details panel we want it to spill over into two cells.

It is important to reset any constraint values such as gridWidth because we are dealing with only one constraints object. The two rows of buttons are looking good. Per default JPanels have a FlowLayout, laying out components from left to right in a centered tutotial. This looks good for what our requirements are.

Of course our label at the top needs to be left aligned, and our table would be good if gridbaglatout had some data in it. Lets move on to our details panel on the right. This panel will also use a GridBagLayout, so we will effectively have two nested GridBagLayouts in our application frame. In this first cut lets just concern ourselves with gridX and gridY constraints:.

A useful technique is to use variables for X and Y coordinates. This makes it extremely easy to add extra fields at a later point in time. All the components are in their correct X and Y positions but the width has to be fixed. The checkbox at the bottom is in its own separate column, so we need to stretch the text fields over to the right.

We do this by setting the gridWidth property to two for those fields that we want to stretch over. Now if we run it, it still looks terrible, but at least we see that we have three columns with most of the text fields sitting over the last two columns. The columns dimension in our text area will be overridden by our GridBagLayout, however tutkrial rows value of 2 will not.

We can put this alongside the insets to affect all components because our anchor does not affect our text field components, only our labels, since they have no FILL set. Our table should also stretch out in both directions, effectively swallowing up any space that may be available.

Weight X and weight Y should be set to 1. Refactor out the ScrollPane and give it a preferred size. This gives you a bit of control over the fill of the table and scrollpane. If you find some of the text fields on yutorial right are collapsing, add some column width via the integer parameter when constructing text fields:. Hey This is really good but for some reason my createDetailsPanel does not show my textfields, labels when i run my program I dont know why.

Do you know what I need to do to ggidbaglayout it to show and can you please put comments on your code so I know what it is used for.

Thank you for your great tutorial, i read it tree times and each time i find something new. Thanks a lot for the example. I was trying out a same screen.
