http://blog.elevenworks.com/?p=4Step 7: Specify the size of the tabs

In order to specify the size of the tabs we need to override the calculateTabHeight method and the calculateTabWidth method. We can also use the calculateTabHeight method to enforce the fact that a tab will always be a height that is divisible by two. This will make sure that the angled line on the right hand side of the tabs always looks good (unlike the screenshots from the previous step).

	protected int calculateTabHeight(int tabPlacement, int tabIndex, int fontHeight)
	{
		int vHeight = fontHeight;
		if (vHeight % 2 > 0)
		{
			vHeight += 1;
		}
		return vHeight;
	}

	protected int calculateTabWidth(int tabPlacement, int tabIndex, FontMetrics metrics)
	{
		return super.calculateTabWidth(tabPlacement, tabIndex, metrics) + metrics.getHeight();
	}

谢谢这么多的代码 就是不是知道干什么用的 一个中国字都没有

[a2068879]

这个是我的代码
ALMModelObject theWorkspaceModel = ALMApplication.message_getWorkspace();
ALMController theWorkspaceController = theWorkspaceModel.newController();
theApplicationController.registerFolder(CoreConstants.keyResultFolders, theWorkspaceController);
ALMTreeBuilderNode theTreeBuilder = new ALMTreeBuilderNode(theWorkspaceController, ALMControllerTreeNodeFactory.sFactory);
theTreeBuilder.setRecursiveBuild(true);

DefaultNamedObject theTabDelegate = new DefaultNamedObject(almLocalized("lbl_resultfolders"));
ImageIcon theIcon = getBundle().getImageIcon("icon-resultfolders.png");
if (theIcon != null)
theTabDelegate.setIcon(theIcon);
theApplicationController.registerTabView(1000, CoreConstants.keyResultFolders,theTabDelegate, theTreeBuilder);
}

感觉是不是你默认的面板的大小小了点 导致你标签字体排版的时候是竖着的？

[realreachard]

查看布局,查看label的size设置

[a2068879]

肯定不是格子设子太小问题 因为放到左侧 也是垂直的

[a2068879]

包括里面的字体 都是垂直的 看的时候需要侧着看

[realreachard]

贴代码上来

[a2068879]

我要是能找到是在什么地方写的 就不麻烦大家了
我想知道有没有这样的属性 我好根据这个属性去找这个代码

[a2068879]

我自己往里面添加标签值就是 水平的 原来的值还是垂直的

[huang_w]

你用到布局了吗？是不是布局设置成竖直方式显示了？
