我一直在玩GridBagLayout
,我似乎无法弄清楚weight
在约束中的特定 ing 中我将获得多少像素。
例如,假设我有一个 1000 像素contentPane
,其中包含三个JPanel
s,权重(例如weighty
)为 0.1、0.1、0.8。
我的第一个假设是面板 1 和 2 各为 100 像素,面板 3 为 800 像素。事实证明并非如此。
如何获得与加权相关的确切像素数?
这个问题提出了同样的问题,但答案虽然有帮助,但并没有回答这个问题。:- /
没关系,我想我在这里找到了答案:
When more than one column has a non-zero weight, the excess space is
distributed among the non-zero weight columns using the weight values.
In particular, if the excess space is P pixels, and the column weights
for column^i is weight^i, then column^i gets exactly
(weight^i * P) / (sum-of-all-column-weights). For example, if column 1
has weight 1 and column 2 has weight 2 and the excess space is 90 pixels,
column 1 will get 30 extra pixels and column 2 will get 60 extra pixels.
Rows with a non-zero weight behave in similar fashion.
显然问题是向单元格添加了额外的空间。
