Java Utililty Methods JComponent Width

void addComponent(Container container, JComponent component, int xPos, int yPos, int width, int height, double weightX, double weightY, int insetTop, int insetLeft, int insetBottom, int insetRight, int anchor, int stretch)
Define the parameter for the gridbaglayout constraints

GridBagConstraints gridConstraints = new GridBagConstraints();
gridConstraints.gridx = xPos;
gridConstraints.gridy = yPos;
gridConstraints.gridwidth = width;
gridConstraints.gridheight = height;
gridConstraints.weightx = weightX;
gridConstraints.weighty = weightY;
gridConstraints.insets = new Insets(insetTop, insetLeft, insetBottom, insetRight);

void adjustNarrowField(final JComponent component, final int width)
Adjust the sizes of the specified component to be a narrower field.

component.setMaximumSize(new Dimension(width, HEIGHT_ROW));

void adjustWidth(JComponent aComponent, int aWidth)
Adjust the size of a component such that it has the specified preferred width.

Dimension preferedSize = aComponent.getPreferredSize();
preferedSize.width = aWidth;
aComponent.setPreferredSize(preferedSize);
