Bir Java SWT penceresinde kaydırma çubuklarını etkinleştirme

Question

Özel çubuklarda görüntülenecek kaydırma çubuklarını nasıl etkinleştiririm.StyledText? Kaydırma çubuklarını görüntüler, ancak custom.StyledText'in kaydırmasına izin vermiyor mu?

Sen ScrolledComposite gerekmez StyledText üzerinde SWT.V_SCROLL stilini kullanın. İşte layouts yerine setBounds ait olan, bir örnek: aynı zamanda bir yatay kaydırma çubuğunu isterseniz

/** 
* Create contents of the window. 
*/ 
protected void createContents() { 
    shlWhois = new Shell(); 
    shlWhois.setSize(450, 300); 
    shlWhois.setText("Whois"); 
    shlWhois.setLayout(new GridLayout(2, false)); 

    Label lblDomain = new Label(shlWhois, SWT.NONE); 
    lblDomain.setLayoutData(GridDataFactory.fillDefaults().create()); 
    lblDomain.setText("Domain"); 

    text = new Text(shlWhois, SWT.BORDER); 
    text.setLayoutData(GridDataFactory.fillDefaults().grab(true, false).create()); 

    final StyledText styledText = new StyledText(shlWhois, SWT.BORDER | SWT.V_SCROLL | SWT.MULTI | SWT.WRAP); 
    styledText.setLayoutData(GridDataFactory.fillDefaults().grab(true, true).span(2, 1).create()); 

    Button btnWhois = new Button(shlWhois, SWT.NONE); 
    btnWhois.setText("Search"); 
} 

Sen stilleri SWT.BORDER | SWT.V_SCROLL | SWT.H_SCROLL | SWT.MULTI kullanabilirsiniz.
