GridBagLayout 变得疯狂

我有一个 GridBagLayout,但一个标签 (maxSizeLbl) 变得疯狂,而另一个标签 (maxDateLbl) 不可见,有人知道我做错了什么吗?

这是图片:

这是代码:

I have a GridBagLayout, but one label (maxSizeLbl) goes crazy and an other one (maxDateLbl) isnt visible, anyone knows what I've done wrong?

Here is the Picture:

您添加了两次 ma​​xSizeLbl(而不是 ma​​xDateLbl

You added the maxSizeLbl twice (instead of maxDateLbl)

确保您彻底学习了 http://madbean.com/anim 中不可或缺的 GridBagLayout 教程/totallygridbag/ 首先。

看来你没有使用任何IDE。 Eclipse 在 maxDateLbl 下面显示了一条奇怪的黄色波浪线——它没有被使用。如果您点击 maxSizeLbl,您会看到它被使用了两次。

将第二个 maxSizeLbl 替换为 maxDateLbl

并再次观看教程。

Make sure you thoroughly study the indispensable GridBagLayout tutorial at http://madbean.com/anim/totallygridbag/ first.

It seems like you don't use any IDE. Eclipse shows a curious yellow squiggly line below maxDateLbl--it's not being used. And if you click on maxSizeLbl, you'll see it's being used twice.

Replace the second maxSizeLbl with maxDateLbl.

And watch the tutorial again.

包括杰弗里关于 maxSizeLbl/maxDateLbl 的发现,这对我有用,并假设字段标签占据文本字段的左侧而不是顶部。 (仅显示相关代码部分。)


addComponent(c, gbl,        rootLbl, 0, 0, 1, 1, 1.0, 0.0);
addComponent(c, gbl,         rootTF, 1, 0, 3, 1, 1.0, 0.0);

addComponent(c, gbl,    containsLbl, 0, 1, 1, 1, 1.0, 0.0);
addComponent(c, gbl,     containsTF, 1, 1, 3, 1, 1.0, 0.0);

addComponent(c, gbl, containsNotLbl, 0, 2, 1, 1, 1.0, 0.0);
addComponent(c, gbl,  containsNotTF, 1, 2, 3, 1, 1.0, 0.0);

addComponent(c, gbl,     minSizeLbl, 0, 3, 1, 1, 1.0, 0.0);
addComponent(c, gbl,      minSizeTF, 1, 3, 1, 1, 1.0, 0.0);
addComponent(c, gbl,     maxSizeLbl, 2, 3, 1, 1, 1.0, 0.0);
addComponent(c, gbl,      maxSizeTF, 3, 3, 1, 1, 1.0, 0.0);

addComponent(c, gbl,      suffixLbl, 0, 4, 1, 1, 1.0, 0.0);
addComponent(c, gbl,       suffixTF, 1, 4, 3, 1, 1.0, 0.0);

addComponent(c, gbl,     minDateLbl, 0, 5, 1, 1, 1.0, 0.0);
addComponent(c, gbl,      minDateTF, 1, 5, 1, 1, 1.0, 0.0);
addComponent(c, gbl,     maxDateLbl, 2, 5, 1, 1, 1.0, 0.0);
addComponent(c, gbl,      maxDateTF, 3, 5, 1, 1, 1.0, 0.0);

addComponent(c, gbl,      searchBtn, 0, 6, 4, 1, 1.0, 0.0);

Including Geoffrey's discovery about maxSizeLbl/maxDateLbl, this is what worked for me and assumes the field labels occupy the left side of the text field and not the top. (Only the relevant section of code shown.)


addComponent(c, gbl,        rootLbl, 0, 0, 1, 1, 1.0, 0.0);
addComponent(c, gbl,         rootTF, 1, 0, 3, 1, 1.0, 0.0);

addComponent(c, gbl,    containsLbl, 0, 1, 1, 1, 1.0, 0.0);
addComponent(c, gbl,     containsTF, 1, 1, 3, 1, 1.0, 0.0);

addComponent(c, gbl, containsNotLbl, 0, 2, 1, 1, 1.0, 0.0);
addComponent(c, gbl,  containsNotTF, 1, 2, 3, 1, 1.0, 0.0);

addComponent(c, gbl,     minSizeLbl, 0, 3, 1, 1, 1.0, 0.0);
addComponent(c, gbl,      minSizeTF, 1, 3, 1, 1, 1.0, 0.0);
addComponent(c, gbl,     maxSizeLbl, 2, 3, 1, 1, 1.0, 0.0);
addComponent(c, gbl,      maxSizeTF, 3, 3, 1, 1, 1.0, 0.0);

addComponent(c, gbl,      suffixLbl, 0, 4, 1, 1, 1.0, 0.0);
addComponent(c, gbl,       suffixTF, 1, 4, 3, 1, 1.0, 0.0);

addComponent(c, gbl,     minDateLbl, 0, 5, 1, 1, 1.0, 0.0);
addComponent(c, gbl,      minDateTF, 1, 5, 1, 1, 1.0, 0.0);
addComponent(c, gbl,     maxDateLbl, 2, 5, 1, 1, 1.0, 0.0);
addComponent(c, gbl,      maxDateTF, 3, 5, 1, 1, 1.0, 0.0);

addComponent(c, gbl,      searchBtn, 0, 6, 4, 1, 1.0, 0.0);
