Eclipse插件，在选项卡标题旁边的轮廓上添加按钮

Question

I have a custom Eclipse plugin with an editor and a content outline on which I added action(button) with

@Override
public void setActionBars(IActionBars actionBars)
{       

    actionBars.getToolBarManager().add(new CustomAction());     
    actionBars.getToolBarManager().update(false);       
    actionBars.updateActionBars();      
}

The button correctly displays and is functional but it is display on a toolbar below the tab header named Outline and I want that button to be displayed next to that tab header like in the JDT.

Two pict to explain:

This is what I have

And what I want

In the JDT the first behavior happens when there is not enough space to display all the button but in my outline the button is always below the tab header

As you can see on the picts I read the JDT outline source code but nothing helped.

Answer 1

我找到了一个解决方案，我的按钮使用的高度图像很大，JDT使用的图像是16x16，所以我只缩小了我的位置，并将按钮移到了选项卡标题旁边。
