我正在嘗試復(fù)制類似于此的UI：

我一直在關(guān)注如何創(chuàng)建表格每列中的按鈕的作者說(shuō)明(沒(méi)有成功).我的項(xiàng)目與他的區(qū)別在于我正在嘗試使用Tree而不是Table,而我正在使用eclipse TreeViewer插件進(jìn)行上下文.從理論上講,實(shí)現(xiàn)似乎應(yīng)該是直截了當(dāng)?shù)?但我似乎無(wú)法讓它發(fā)揮作用.

這是我的代碼,它很容易復(fù)制,因?yàn)樗皇菐в衪reeviewer的示例Java PDT sampleview,以及createPartControl中的十幾個(gè)額外行.你在這里看不到的一切都和樣品一樣：

class ViewLabelProvider extends LabelProvider implements ITableLabelProvider {

public String getColumnText(Object obj, int i) {

if(i == 0){

return obj.toString();

}

return "";

}

public Image getColumnImage(Object obj, int i) {

if(i == 0){

String imageKey = ISharedImages.IMG_OBJ_ELEMENT;

if (obj instanceof TreeParent)

imageKey = ISharedImages.IMG_OBJ_FOLDER;

return PlatformUI.getWorkbench().getSharedImages().getImage(imageKey);

}

return null;

}

}

class NameSorter extends ViewerSorter {

}

/**

* The constructor.

*/

public ButtonView() {

}

* to create the viewer and initialize it.
