Java JPanels>；JTabbedPane>；JFrame。GridBagContraints面板未启动

我不想进入我的选项卡窗格面板gridbagconstraints gridx和gridy index start top lef side。但总是从中心开始。我尝试设置框架gridbaglayout和GridBagContracts锚定西北。仍在中间开始索引。我必须为面板索引从左上角开始做什么？ 这是我的秋千课

可能与我创建的容器边框布局和选项卡窗格添加的容器重复。但现在选项卡式窗格从中间开始。选项卡窗格面板gridbagcontraints的gridx和gridy索引仍在中间。您需要设置某些单元格的权重X和权重。感谢@VGR的帮助。它的工作。
