這裏是我的示例代碼,我在我的課上有一個名爲CommentPage的部分,擴展了FormPage,我在本節中使用了一個滾動組合框來顯示一些內容,但它確實有效,劑量誰知道爲什麼?如何顯示swt節中的滾動複合內容
public class CommentPage extends FormPage{
private FormToolkit toolkit;
public CommentPage (FormEditor editor, String id, String title) {
super(editor, id, title);
}
@Override
protected void createFormContent(IManagedForm managedForm) {
// TODO Auto-generated method stub
super.createFormContent(managedForm);
toolkit = managedForm.getToolkit();
form = managedForm.getForm();
toolkit.decorateFormHeading(form.getForm());
form.setText(currVersion.getcName()+currVersion.getvName());
Composite superContainer = form.getBody();
superContainer.setLayout(new GridLayout(2,false));
superContainer.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
createAreas(superContainer);
}
private void createAreas(Composite superContainer) {
Composite left = toolkit.createComposite(superContainer, SWT.NONE);
Composite right = toolkit.createComposite(superContainer, SWT.NONE);
GridData leftGrid = new GridData(SWT.FILL,SWT.FILL,true,true);
left.setLayoutData(leftGrid);
left.setLayout(new GridLayout(1,true));
GridData rightGrid = new GridData(SWT.FILL,SWT.FILL,true,true);
right.setLayoutData(new GridData(SWT.FILL,SWT.FILL,true,true));
right.setLayout(new GridLayout(1,true));
commentArea(right);
}
private void commentArea(Composite superContainer) {
Section section = toolkit.createSection(superContainer, Section.TITLE_BAR|Section.TWISTIE|Section.EXPANDED);
section.setText("Comment"); //$NON-NLS-1$
section.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
section.setLayout(new FillLayout());
Composite container = toolkit.createComposite(section, SWT.NONE);
container.setLayout(new GridLayout(1, true));
section.setClient(container);
ScrolledComposite scrollContainer = new ScrolledComposite(container, SWT.V_SCROLL|SWT.BORDER);
scrollContainer.setLayoutData(new GridData(SWT.FILL,SWT.FILL,true,false));
scrollContainer.setExpandVertical(true);
scrollContainer.setAlwaysShowScrollBars(true);
Color white = Display.getCurrent().getSystemColor(SWT.COLOR_WHITE);
scrollContainer.setBackground(white);
Composite scrollInner = new Composite(scrollContainer, SWT.NONE);
scrollInner.setBackground(white);
scrollInner.setLayout(new GridLayout(1,false));
Label text = toolkit.createLabel(scrollInner, "test1test2test3");
text.setLayoutData(new GridData());
scrollContainer.setContent(scrollInner);
//scrollContainer.setMinSize(scrollInner.computeSize(SWT.DEFAULT, SWT.DEFAULT));
}
}
我的問題:爲什麼 在方法commentArea
didnt在scrolledContainer
標籤中的文本"test1test2test3"
顯示?
它的工作原理,加想再問一個問題,爲什麼如果scrollInner中有很多內容,爲什麼scrolledComposite不滾動,而是scorlledForm滾動? – star
