Select Horizontal in the Fill combobox and press Enter. Docs for Earlier Releases. You can see in the code extract above that Button 5 specifies that it should be displayed at the end of the display area by setting an anchor at GridBagConstraints.

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. Instead of invoking methods on a GridBagConstraints object, you manipulate its instance variables, as described in Specifying Constraints.

April 5, at This resizing behavior is based on weights the program assigns to individual components in the GridBagLayout. The button in the second row spans all the columns; the button in the third row spans the two right columns. Since the preferred size of the combobox is smaller than the size of the corresponding cell, the GridBagLayout places the component into the center of the cell by default. To separate them, do the following:. To put space between buttons 4 and 5, we used insets to add a minimum of 10 pixels above button 5, and we made button 5 hug the bottom edge of its cell.

Values that are different from those in the previous table entry are marked in italics. This is the best tutorial I have used yet! We do this by setting the gridWidth property to two for those fields that we want to stretch over. If you enlarge the window as shown in the following figure, you’ll notice that the bottom row, which contains Button 5, gets all the new vertical space.
