e629. setting the location of a component within the cell of a gridbaglayout using anchors.txt

这里面包含了一百多个JAVA源文件

By default, when the cell is larger than the preferred size of a component, the component is centered within the cell. You can specify other relative positions using the anchor constraint. For example, specifying an anchor of NORTH causes the component to be horizontally centered with the top edge of the component aligned with the top edge of the cell. Specifying an anchor of NORTHEAST causes the northeast corner of the component to coincide with the northeast corner of the cell. 
See e622 Creating a GridBagLayout for an example on how to use a gridbag layout with gridbag constraints. 

    GridBagConstraints gbc = new GridBagConstraints();
    
    // These are the nine possible anchor values
    gbc.anchor = GridBagConstraints.CENTER;
    gbc.anchor = GridBagConstraints.NORTH;
    gbc.anchor = GridBagConstraints.NORTHEAST;
    gbc.anchor = GridBagConstraints.EAST;
    gbc.anchor = GridBagConstraints.SOUTHEAST;
    gbc.anchor = GridBagConstraints.SOUTH;
    gbc.anchor = GridBagConstraints.SOUTHWEST;
    gbc.anchor = GridBagConstraints.WEST;
    gbc.anchor = GridBagConstraints.NORTHWEST;
