GridBagLayout给了我意想不到的行为

我有以下代码，我需要创建一个网格，15个项目分为两列，在第6行，只有一个项目将取代2个项目。

我希望看到两个具有相同水平宽度的列，但我得到的是不同的，第一列占整个大小的三分之一，而另一列占三分之二，为什么会发生这种情况？ 

Insets ins = new Insets(0,0,0,0);
GridBagConstraints SymbolTextc           = new GridBagConstraints(0, 0, 1, 1, 1, 1, GridBagConstraints.CENTER, GridBagConstraints.NONE,ins,0,0);
GridBagConstraints SymbolLabelc          = new GridBagConstraints(1, 0, 1, 1, 1, 1, GridBagConstraints.CENTER, GridBagConstraints.NONE,ins,0,0); 
GridBagConstraints ComapnyTextc          = new GridBagConstraints(0, 1, 1, 1, 1, 1, GridBagConstraints.CENTER, GridBagConstraints.NONE,ins,0,0);
GridBagConstraints ComapnyLabelc         = new GridBagConstraints(1, 1, 1, 1, 1, 1, GridBagConstraints.CENTER, GridBagConstraints.NONE,ins,0,0);
GridBagConstraints PriceTextc            = new GridBagConstraints(0, 2, 1, 1, 1, 1, GridBagConstraints.CENTER, GridBagConstraints.NONE,ins,0,0);
GridBagConstraints PriceLabelc           = new GridBagConstraints(1, 2, 1, 1, 1, 1, GridBagConstraints.CENTER, GridBagConstraints.NONE,ins,0,0);
GridBagConstraints MaxQtyTextc           = new GridBagConstraints(0, 3, 1, 1, 1, 1, GridBagConstraints.CENTER, GridBagConstraints.NONE,ins,0,0);
GridBagConstraints MaxQtyLabelc          = new GridBagConstraints(1, 3, 1, 1, 1, 1, GridBagConstraints.CENTER, GridBagConstraints.NONE,ins,0,0);
GridBagConstraints PurchasePowerTextc    = new GridBagConstraints(0, 4, 1, 1, 1, 1, GridBagConstraints.CENTER, GridBagConstraints.NONE,ins,0,0);
GridBagConstraints PurchasePowerLabelc   = new GridBagConstraints(1, 4, 1, 1, 1, 1, GridBagConstraints.CENTER, GridBagConstraints.NONE,ins,0,0);
GridBagConstraints NewCoverageTextc      = new GridBagConstraints(0, 5, 1, 1, 1, 1, GridBagConstraints.CENTER, GridBagConstraints.NONE,ins,0,0);
GridBagConstraints NewCoverageLabelc     = new GridBagConstraints(1, 5, 1, 1, 1, 1, GridBagConstraints.CENTER, GridBagConstraints.NONE,ins,0,0);
GridBagConstraints NoteLabelc            = new GridBagConstraints(0, 6, 2, 1, 1, 1, GridBagConstraints.CENTER, GridBagConstraints.NONE,ins,0,0);
GridBagConstraints CancelButtonc         = new GridBagConstraints(0, 7, 1, 1, 1, 1, GridBagConstraints.CENTER, GridBagConstraints.HORIZONTAL,ins,0,0);
GridBagConstraints OkButtonc             = new GridBagConstraints(1, 7, 1, 1, 1, 1, GridBagConstraints.CENTER, GridBagConstraints.HORIZONTAL,ins,0,0);

所以，我把你的代码放到一个可运行的例子中并得到......

GridBagLayout

愿意进一步指出你不喜欢的东西，可能以runnable example和屏幕拍摄的形式（你得到的和你期望的）

答案 1 :(得分：0)

以编程方式处理您的 x 和 y 值，如下所示：

int gridcol1 = 0;
int gridcol2 = 1;


Insets ins = new Insets(0,0,0,0);

int y=0;
GridBagConstraints SymbolTextc           = new GridBagConstraints(gridcol1, y, 1, 1, 1, 1, GridBagConstraints.CENTER, GridBagConstraints.NONE,ins,0,0);
GridBagConstraints SymbolLabelc          = new GridBagConstraints(gridcol2, y, 1, 1, 1, 1, GridBagConstraints.CENTER, GridBagConstraints.NONE,ins,0,0); 

y++;

GridBagConstraints ComapnyTextc          = new GridBagConstraints(gridcol1, y, 1, 1, 1, 1, GridBagConstraints.CENTER, GridBagConstraints.NONE,ins,0,0);
GridBagConstraints ComapnyLabelc         = new GridBagConstraints(gridcol2, y, 1, 1, 1, 1, GridBagConstraints.CENTER, GridBagConstraints.NONE,ins,0,0);

y++;

GridBagConstraints PriceTextc            = new GridBagConstraints(gridcol1, y, 1, 1, 1, 1, GridBagConstraints.CENTER, GridBagConstraints.NONE,ins,0,0);
GridBagConstraints PriceLabelc           = new GridBagConstraints(gridcol2, y, 1, 1, 1, 1, GridBagConstraints.CENTER, GridBagConstraints.NONE,ins,0,0);

y++;

GridBagConstraints MaxQtyTextc           = new GridBagConstraints(gridcol1, y, 1, 1, 1, 1, GridBagConstraints.CENTER, GridBagConstraints.NONE,ins,0,0);
GridBagConstraints MaxQtyLabelc          = new GridBagConstraints(gridcol2, y, 1, 1, 1, 1, GridBagConstraints.CENTER, GridBagConstraints.NONE,ins,0,0);

y++;

GridBagConstraints PurchasePowerTextc    = new GridBagConstraints(gridcol1, y, 1, 1, 1, 1, GridBagConstraints.CENTER, GridBagConstraints.NONE,ins,0,0);
GridBagConstraints PurchasePowerLabelc   = new GridBagConstraints(gridcol2, y, 1, 1, 1, 1, GridBagConstraints.CENTER, GridBagConstraints.NONE,ins,0,0);

如果按照我的描述进行操作，那么您将看到问题所在。
