When you build your application visually using GridBagLayout,
the visual grid markers help you to move and drop components in the
required position.
About this task
To add or move components within GridBagLayout:
Procedure
- Select the Swing component from the palette that you want
to add to your GridBagLayout, or click and drag the existing component
that you want to move within your GridBagLayout.
- Move your mouse pointer over the position where you want
to drop or move the component:
- If you point to a grid cell that is already occupied by another
component, you cannot move or drop in that position.
- If you point to a grid cell that is empty, the cell turns
dark gray to indicate the valid drop position. The cursor shows the
X and Y grid values for the drop position. The first number is the
X value, which represents the column, and the second number is the
Y value, which represents the row.
- If you position your cursor on a grid boundary, a yellow bar
indicates that a new column or row number are added.
- If any new column or row number is being added by your placement,
the background color yellow shows on the cursor X/Y indicator and
on the column and row labels. Components that are in rows or columns
with yellow circles are updated to reflect the new grid X/Y values.
- Click or release your mouse to drop the component in the
position that you selected.
