如何修复 SWT 中按钮的顺序? [英] how to fix the order of the buttons in SWT?

问题描述

我有 2 个按钮的滚动条

I have scroller with 2 buttons

如何设置按钮的顺序将在相同的原始数据中而不是每个控件中:按钮滚动条和按钮将在不同的行中

How i can set that the order of the buttons will be in the same raw and not each control : button scroller and button will be in different row

    fComposite= new Composite(composite, SWT.RIGHT_TO_LEFT);
    GridData layoutData= new GridData(SWT.FILL, SWT.RIGHT_TO_LEFT, true, false);
    fComposite.setLayoutData(layoutData);
    layout= new GridLayout(1, false);
    layout.marginHeight= 0;
    layout.marginWidth= 0;
    layout.horizontalSpacing= 0;
    layout.verticalSpacing= 0;

    fComposite.setLayout(layout);

    Display display = parent.getDisplay();
    Shell shell = parent.getShell(); 
    Button button = new Button(fComposite, SWT.LEFT);
    button.setText("Two"); //$NON-NLS-1$
    button.setImage(display.getSystemImage(ICON_1));    

    final Scale scale = new Scale (fComposite, SWT.BORDER);
    Rectangle clientArea = fComposite.getClientArea ();
    scale.setBounds (clientArea.x, clientArea.y, 200, 64);
    scale.setMaximum (5);
    scale.setPageIncrement (1);
    scale.setSelection(5);

    Button rButton = new Button(fComposite, SWT.RIGHT);
    rButton.setText("Two"); //$NON-NLS-1$
    rButton.setImage(display.getSystemImage(ICON_2));   

推荐答案

您是否阅读了我在您的其他问题之一中发布的有关 SWT 布局的文章?

Did you read the article about SWT layouts that I posted in one of your other questions?

Display 和 Shell 是首先要创建的东西.之后，您可以向 shell 添加内容.

The Display and Shell are the first things to create. After that you can add things to the shell.

您的问题是基于这样一个事实，即您创建了一个只有一列的 GridLayout.因此，所有小部件都位于彼此下方.

Your problem is based on the fact, that you created a GridLayout with just one column. Thus all widgets are below each other.

layout= new GridLayout(1, false);

第一个参数是列数.对于三列，将其设置为 3.

The first parameter is the number of columns. Set it to 3 for three columns.

请阅读布局和文章的文档:在提出进一步问题之前了解 SWT 中的布局.一定能帮到你.

Please read the documentation of the layout and the article: Understanding layouts in SWT before asking further questions. It will definitely help you.
