试一下吧!
这个程序由2个类组成:
HexagonButton
,使用Graphics在JButton
中绘制六边形。当调用getRow
或getCol
时,它还会返回行和列的值。
HexagonPattern
是主类。它通过使用setBounds(x, y, width, height)
来布置六边形图案。它使用ActionListener
通过调用getRow
和getCol
来打印单击的六边形的坐标。
就像我说的那样,这不是最好的程序。如果你想让六边形变小,那么你将不得不改变很多变量。
JButton
并自己绘制形状、使用Border
或Image
,它仍然是矩形,因此几乎所有的布局管理器都无法按照您想要的方式排列它们。这将需要完全自定义绘画路线或自定义布局管理器。 - MadProgrammerPolygon::contains
