包路径：java.awt.GridBagLayout
类名称：GridBagLayout
[英]The GridBagLayout class is a flexible layout manager that aligns components vertically and horizontally, without requiring that the components be of the same size. Each GridBagLayout object maintains a dynamic, rectangular grid of cells, with each component occupying one or more cells, called its display area.
Each component managed by a GridBagLayout is associated with an instance of GridBagConstraints. The constraints object specifies where a component's display area should be located on the grid and how the component should be positioned within its display area. In addition to its constraints object, the GridBagLayout also considers each component's minimum and preferred sizes in order to determine a component's size.
Grid coordinate (0,0) is in the upper left corner of the container with x increasing to the right and y increasing downward.
To use a grid bag layout effectively, you must customize one or more of the GridBagConstraints objects that are associated with its components. You customize a GridBagConstraints object by setting one or more of its instance variables:
GridBagConstraints#gridx, GridBagConstraints#gridySpecifies the cell at the upper left of the component's display area, where the cell at the origin of the grid has address gridx = 0, gridy = 0. Use GridBagConstraints.RELATIVE (the default value) to specify that the component be placed immediately following (along the x axis for gridx or the y axis for gridy) the component that was added to the container just before this component was added. GridBagConstraints#gridwidth, GridBagConstraints#gridheightSpecifies the number of cells in a row (for gridwidth) or column (for gridheight) in the component's display area. The default value is 1. Use GridBagConstraints.REMAINDER to specify that the component be the last one in its row (for gridwidth) or column (for gridheight). Use GridBagConstraints.RELATIVE to specify that the component be the next to last one in its row (for gridwidth) or column (for gridheight). GridBagConstraints#fillUsed when the component's display area is larger than the component's requested size to determine whether (and how) to resize the component. Possible values are GridBagConstraints.NONE (the default), GridBagConstraints.HORIZONTAL (make the component wide enough to fill its display area horizontally, but don't change its height), GridBagConstraints.VERTICAL (make the component tall enough to fill its display area vertically, but don't change its width), and GridBagConstraints.BOTH (make the component fill its display area entirely). GridBagConstraints#ipadx, GridBagConstraints#ipadySpecifies the component's internal padding within the layout, how much to add to the minimum size of the component. The width of the component will be at least its minimum width plus (ipadx * 2) pixels (since the padding applies to both sides of the component). Similarly, the height of the component will be at least the minimum height plus (ipady * 2) pixels. GridBagConstraints#insetsSpecifies the component's external padding, the minimum amount of space between the component and the edges of its display area. GridBagConstraints#anchorUsed when the component is smaller than its display area to determine where (within the display area) to place the component.
Valid values are:
GridBagConstraints.NORTHGridBagConstraints.SOUTHGridBagConstraints.WESTGridBagConstraints.EASTGridBagConstraints.NORTHWESTGridBagConstraints.NORTHEASTGridBagConstraints.SOUTHWESTGridBagConstraints.SOUTHEASTGridBagConstraints.CENTER (the default)GridBagConstraints#weightx, GridBagConstraints#weightyUsed to determine how to distribute space, which is important for specifying resizing behavior. Unless you specify a weight for at least one component in a row (weightx) and column (weighty), all the components clump together in the center of their container. This is because when the weight is zero (the default), the GridBagLayout object puts any extra space between its grid of cells and the edges of the container.
The following figure shows ten components (all buttons) managed by a grid bag layout:
Each of the ten components has the fill field of its associated GridBagConstraints object set to GridBagConstraints.BOTH. In addition, the components have the following non-default constraints:
weightx = 1.0weightx = 1.0, gridwidth = GridBagConstraints.REMAINDERgridwidth = GridBagConstraints.REMAINDERgridwidth = GridBagConstraints.RELATIVEgridwidth = GridBagConstraints.REMAINDERgridheight = 2, weighty = 1.0gridwidth = GridBagConstraints.REMAINDERNote: The following code example includes classes that do not appear in this specification. Their inclusion is purely to serve as a demonstration.
Here is the code that implements the example shown above:

}
public void init() {
GridBagLayout gridbag = new GridBagLayout();
GridBagConstraints c = new GridBagConstraints();
setFont(new Font("Helvetica", Font.PLAIN, 14));
setLayout(gridbag);

setSize(300, 100);
}

Frame f = new Frame("GridBag Layout Example");

}
}[中]GridBagLayout类是一个灵活的布局管理器，它可以垂直和水平对齐组件，而不需要组件具有相同的大小。每个GridBagLayout对象维护一个动态的矩形单元格网格，每个组件占用一个或多个单元格，称为其显示区域。
由GridBagLayout管理的每个组件都与GridBagConstraints的一个实例相关联。约束对象指定零部件的显示区域在栅格上的位置以及零部件在其显示区域内的定位方式。除了约束对象外，GridBagLayout还考虑每个组件的最小和首选尺寸，以确定组件的尺寸。
栅格坐标（0,0）位于容器的左上角，x向右增加，y向下增加。
要有效使用网格包布局，必须自定义与其组件关联的一个或多个GridBagConstraints对象。通过设置GridBagConstraints对象的一个或多个实例变量，可以自定义该对象：
GridBagConstraints#gridx，GridBagConstraints#Gridy指定组件显示区域左上方的单元格，其中位于网格原点的单元格具有地址gridx = 0、gridy = 0。使用GridBagConstraints.RELATIVE（默认值）指定在添加此组件之前添加到容器中的组件紧随其后（沿gridx的x轴或gridy的y轴）。GridBagConstraints#gridwidth、GridBagConstraints#GridHeights指定组件显示区域中的行（对于gridwidth）或列（对于gridheight）中的单元格数。默认值为1。使用GridBagConstraints.REMAINDER指定组件是其行（对于gridwidth）或列（对于gridheight）中的最后一个组件。使用GridBagConstraints.RELATIVE指定组件是其行（对于gridwidth）或列（对于gridheight）中倒数第二个组件。GridBagConstraints#Fill当组件的显示区域大于组件请求的大小时，用于确定是否（以及如何）调整组件的大小。可能的值有GridBagConstraints.NONE（默认值）、GridBagConstraints.HORIZONTAL（使组件宽度足以水平填充其显示区域，但不更改其高度）、GridBagConstraints.VERTICAL（使组件高度足以垂直填充其显示区域，但不更改其宽度）和GridBagConstraints.BOTH（使组件完全填充其显示区域）。GridBagConstraints#ipadx，GridBagConstraints#iPads指定布局中组件的内部填充，以及添加到组件最小尺寸的量。组件的宽度将至少为其最小宽度加上(ipadx * 2)像素（因为填充应用于组件的两侧）。类似地，组件的高度将至少为最小高度加上(ipady * 2)像素。GridBagConstraints#Insets指定组件的外部填充、组件与其显示区域边缘之间的最小空间量。GridBagConstraints#锚点当组件小于其显示区域时用于确定放置组件的位置（在显示区域内）。
有效值为：
GridBagConstraints.NORTHGridBagConstraints.SOUTHGridBagConstraints.WESTGridBagConstraints.EASTGridBagConstraints.NORTHWESTGridBagConstraints.NORTHEASTGridBagConstraints.SOUTHWESTGridBagConstraints.SOUTHEASTGridBagConstraints.CENTER（默认值）weightx和列（weighty中的至少一个组件指定权重，否则所有组件都会在其容器的中心聚集在一起。这是因为当权重为零（默认值）时，GridBagLayout对象在其单元格网格和容器边缘之间放置任何额外的空间。GridBagConstraints对象的fill字段设置为GridBagConstraints.BOTH。此外，组件具有以下非默认约束：weightx = 1.0weightx = 1.0，gridwidth = GridBagConstraints.REMAINDERgridwidth = GridBagConstraints.REMAINDERgridwidth = GridBagConstraints.RELATIVEgridwidth = GridBagConstraints.REMAINDERgridheight = 2，weighty = 1.0gridwidth = GridBagConstraints.REMAINDERimport java.awt.*;
