如何让Windows Form上的控件跟随窗体的缩放而自适应大小

Answer 1

简单的来说就是监控，定位+保持比例。

例如界面分为左右下三部分，其中下部分最好解决。使用Dock属性直接定位到Bottom。难点就是上面的左右两块。

我的做法是：外面套一层，然后分割为左右两部分。这里采用TableLayoutPanel为例。将TableLayoutPanel调整为一行两列左右各占50%的单元格形式。

并将TableLayoutPanel的Dock属性调整为Fill。这样两个控件就会各占上下两部分。

这时候可以运行，会发现无论窗体大小怎么变，控件都是会自动调整。不会死板板的。

下面是重点：

放两个需要测试的控件分别到TableLayoutPanel的两个单元格中。我这里放的是ListBox。然后将两个ListBox的Anchor属性都设为Top,Bottom,Left,Right。既上下左右。最后调整两个ListBox到合适大小。好了，完事。。。

 

下面贴出的是Designer部分的代码。直接粘贴进去看效果吧

如不雅你的控件须要填满全部窗口空间，例如显示数据用的DBGrid，可以设置DBGrid的Align属性为caClient，如许在窗口调剂大大小时，DBGrid就会主动调剂大大小了。然则如不雅是象DBEdit之类的小控件，就只能如同lichp兄所说，在Form的Resize事宜中根据调剂后的窗口大大小计算出每个控件的Left、Top、Width、Height属性，用法度榜样来调剂了。
