照着葫芦画，CComboViewer

我的代码中有一个 ComboViewer, 不过在Window 2000，Form 中，样式有点难看，有讨厌的三维边框。
而 FormToolkit 只对 CCombo 控件 进行细边框绘制（FormToolkit.paintBorderFor(...)）
所以我依照 ComboViewer “抄” 了一个 CComboViewer。

java 代码

package com.longthsoft.rcppart.ui.parts;

import org.eclipse.jface.viewers.AbstractListViewer;
import org.eclipse.swt.SWT;
import org.eclipse.swt.custom.CCombo;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Control;

public class CComboViewer extends AbstractListViewer {

    private CCombo combo;

    public CComboViewer(Composite parent) {
        this(parent, SWT.READ_ONLY | SWT.BORDER);
    }

    public CComboViewer(Composite parent, int style) {
        this(new CCombo(parent, style));
    }

    public CComboViewer(CCombo list) {
        this.combo = list;
        hookControl(list);
    }

    public CCombo getCCombo() {
        return combo;
    }

    @Override
    public Control getControl() {
        return combo;
    }

    @Override
    protected void listAdd(String string, int index) {
        combo.add(string, index);
    }

    @Override
    protected void listDeselectAll() {
        combo.deselectAll();
        combo.clearSelection();
    }

    @Override
    protected int listGetItemCount() {
        return combo.getItemCount();
    }

    @Override
    protected int[] listGetSelectionIndices() {
        return new int[] { combo.getSelectionIndex() };
    }

    @Override
    protected void listRemove(int index) {
        combo.remove(index);
    }

    @Override
    protected void listRemoveAll() {
        combo.removeAll();
    }

    @Override
    protected void listSetItem(int index, String string) {
        combo.setItem(index, string);
    }

    @Override
    protected void listSetItems(String[] labels) {
        combo.setItems(labels);
    }

    @Override
    protected void listSetSelection(int[] ixs) {
        for (int idx = 0; idx < ixs.length; idx++) {
            combo.select(ixs[idx]);
        }
    }

    @Override
    protected void listShowSelection() {
        return;
    }

    @Override
    public void reveal(Object element) {
        return;
    }

}
