在这里我有一个问题，我希望你能帮我解决。感谢所有希望这样做的人。图形对象不可见时，我打电话重绘方法
我有继承JComponent类的对象，我添加了MouseListener。
我有一个继承面板的网格。
我想在网格中逐个添加对象，以便在我的网格中至少有两个相似或不同的表单。 在添加时，我希望在给定的位置（我们刚刚点击的位置）发生这种情况，同时避免JComponents类型的对象互相堆叠在一起，或者它们的交集给出的不是空集或直线部分（a分割）。 因此，为了避免它的烦恼，我认为无论您在点击网格/网格之后添加点，检查获得的点是否已经在继承JComponent的对象内，并且周围的框数量是否足够。 但它仍然不起作用。即使要添加的对象未出现在网格中（实施方法在GrilleIHM#mouseClicked方法中）。
我试图通过创建一个类来代替在所有表单（I 8）中都有相同的代码，但没有成功，从而集中化点击对象的行为。所以我放弃了这个想法。
在Java中为零，我已经通过教程和论坛进行了深入研究。但是二十天后我根本没有前进。
我知道我一次需求太多，但现在我不再找到解决方案。
谢谢你帮助我。
这是我的代码：
