水平滚动条在CTabItem内部的复合下不起作用 [英] Horizontal Scrollbar is not working under composite inside a CTabItem
本文介绍了水平滚动条在CTabItem内部的复合下不起作用的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有一个CtabItem,里面有一个Composite小部件。
然后,我在其中添加了一些组件。
代码如下:-
I have CtabItem inside which, there is a Composite widget. Then, I have added a few components inside it. The code goes like this -
Composite composite = new Composite(tabFolder, SWT.H_SCROLL);
tabItem.setControl(composite);
Label lblName = new Label(composite, SWT.NONE);
lblName.setBounds(10, 28, 55, 15);
lblName.setText("Name");
textName = new StyledText(composite, SWT.BORDER);
String myText = tree.getSelection()[0].getText();
textName.setText(myText);
Point textNamesize = textName.computeSize(SWT.DEFAULT, SWT.DEFAULT);
textName.setBounds(76, 28, textNamesize.x, 21);
Label lblPath = new Label(composite, SWT.NONE);
lblPath.setBounds(10, 83, 55, 15);
lblPath.setText("Path");
textPath = new StyledText(composite, SWT.READ_ONLY);
textPath.setBackground(new Color(d, 240, 240, 240));
Button saveButton = new Button(composite, SWT.NONE);
saveButton.setBounds(456, 134, 75, 25);
saveButton.setText("Save");
Button cancelButton = new Button(composite, SWT.NONE);
cancelButton.setBounds(548, 134, 75, 25);
cancelButton.setText("Cancel");
但是,当我显示选项卡时,会出现滚动条,但是,当我滚动合成时,滚动条会移动,但是滚动条另一侧的元素不会显示
任何,知道为什么它不起作用吗?
But, when I am displaying the tab, the scrolls are present, but, when I am scrolling the composite, the scroll bar moves , but the elements on the other side of the scroll are not showing Any, idea why it is not working ?
谢谢!
推荐答案
来自GGrec的 answer 我为您创建了代码段。
我已经将ScrolledComposite与GridLayout一起使用。
from GGrec's answer I created snippet for you. I have used ScrolledComposite with GridLayout. Hope it will make your task easier.
final ScrolledComposite scrolledComposite = new ScrolledComposite(parent, SWT.BORDER | SWT.H_SCROLL | SWT.V_SCROLL);
scrolledComposite.setExpandHorizontal(true);
scrolledComposite.setExpandVertical(true);
final Composite composite_parent = new Composite(scrolledComposite, SWT.NONE);
composite_parent.setLayout(new GridLayout(3, false));
scrolledComposite.setContent(composite_parent);
scrolledComposite.setSize(composite_parent.computeSize(SWT.DEFAULT, SWT.DEFAULT));
final Composite composite_child = new Composite(composite_parent, SWT.NONE);
composite_child.setLayout(new GridLayout(2, false));
final Label lblDefault1 = new Label(composite_child, SWT.NONE);
lblDefault1.setLayoutData(new GridData(SWT.RIGHT, SWT.CENTER, false, false, 1, 1));
lblDefault1.setText("Name");
final StyledText textStyled = new StyledText(composite_child, SWT.NONE);
textStyled.setLayoutData(new GridData(SWT.LEFT, SWT.CENTER, true, false, 1, 1));
Label lblNewLabel_1 = new Label(composite_child, SWT.NONE);
lblNewLabel_1.setLayoutData(new GridData(SWT.RIGHT, SWT.CENTER, false, false, 1, 1));
lblNewLabel_1.setText("Path");
text = new Text(composite_child, SWT.BORDER);
text.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, true, false, 1, 1));
scrolledComposite.setMinSize(composite_parent.computeSize(SWT.DEFAULT, SWT.DEFAULT));
