水平滚动条在CTabItem内部的复合下不起作用

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 = textNameputeSize(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_parentputeSize(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_parentputeSize(SWT.DEFAULT, SWT.DEFAULT));
