在Eclipse的RCP中使用TWaver

剛開始時，是將TWaver的樹和面板放在一個SWT_AWT的Frame中，此時感覺到閃爍，但后來，由于Swing的分隔條太難看，而將TWaver的樹和面板分別放到各自的SWT_AWT的Frame中，此時的閃爍就很歷害，經過幾次試驗，將TWaver的TNetwork改成雙緩沖方式，此時操作基本上就沒有閃爍了，但樹則沒辦法,具體代碼如下：

private void CreateTWaver() {

GridLayout gridLayout = new GridLayout();

gridLayout.horizontalSpacing = 0;

gridLayout.marginWidth = 0;

gridLayout.marginHeight = 0;

gridLayout.verticalSpacing = 0;

// 整個工作區的容器

container = new SashForm(body, SWT.NONE);

container.setLayoutData(new GridData(GridData.FILL_BOTH));

// 樹形部分

Composite navigate = new Composite(container, SWT.EMBEDDED | SWT.BORDER);

navigate.setLayout(gridLayout);

navigate.setLayoutData(new GridData(GridData.FILL_BOTH));

// 操作面板

Composite workarea = new Composite(container, SWT.EMBEDDED | SWT.NONE);

workarea.setLayout(gridLayout);

workarea.setLayoutData(new GridData(GridData.FILL_BOTH));

container.setWeights(new int[] { 1, 3 });

final Frame netFrame = SWT_AWT.new_Frame(workarea);

netFrame.setLayout(new BorderLayout());

box = new TDataBox("");

network = new TNetwork(box);

network.setName("xxx.network");

network.setToolbarByName(null);

network.clearMovableFilters();

network.setDoubleBuffered(true);

network.getCanvas().addMouseListener(new MouseAdapter() {

@Override

public void mouseClicked(final MouseEvent e) {

if (selectTool == null)

return;

getParent().getDisplay().asyncExec(new Runnable() {

public void run() {

executeSelectTool(selectTool, e.getPoint());

}

});

}

});

// 在元素上雙擊時打開對應的編輯器

network.addElementDoubleClickedActionListener(new ActionListener() {

public void actionPerformed(ActionEvent e) {

if (e.getSource() instanceof Element) {

openElementEditor((Element) e.getSource());

}

});

netFrame.add(network);

final Frame treeFrame = SWT_AWT.new_Frame(navigate);

treeFrame.setLayout(new BorderLayout());

tree = new TTree(box);

tree.setName("xxx.tree");

tree.setEnsureVisibleOnSelected(true);

treeFrame.add(tree);

}
