如何在父组合中对齐两个复合体，而不使用widthHint和heightHint [英] How to align two composites in a parent composite without using widthHint and heightHint

问题描述

这是我的代码如何：

  Composite composite =（Composite）super.createDialogArea（parent）; 
 
复合rowComposite = new Composite（composite，SWT.NONE）; 
 rowComposite.setLayout（new GridLayout（2，false））; 
 GridData gd1 = new GridData（SWT.LEFT，SWT.CENTER，false，false）; 
 gd1.widthHint = 760; 
 gd1.heightHint = 240; 
 rowComposite.setLayoutData（gd1）; 
 
复合columnComposite = new Composite（composite，SWT.NONE）; 
 columnComposite .setLayout（new GridLayout（2，false））; 
 GridData gd2 = new GridData（SWT.LEFT，SWT.CENTER，false，false）; 
 gd2.widthHint = 760; 
 gd2.heightHint = 240; 
 columnComposite .setLayoutData（gd1）; 
  

这里，im使用widthHint和heightHint，不推荐整个布局，用户决定更改系统字体或分辨率。

如何使用widthhint和heightHint实现相同的wihtout。

解决方案

从两个复合和更新的网格数据中移除widthHint和heightHint如下：
new GridData（SWT.FILL，SWT.FILL，true，true）;

GridLayout已经处理了宽度和高度。

I want two composites(one below the other) inside a parent component.

This is how my code looks like:

Composite composite = (Composite) super.createDialogArea(parent);

Composite rowComposite = new Composite(composite, SWT.NONE);
rowComposite.setLayout(new GridLayout(2, false));
GridData gd1 = new GridData(SWT.LEFT, SWT.CENTER, false, false);
gd1.widthHint = 760;
gd1.heightHint = 240;
rowComposite.setLayoutData(gd1);

Composite columnComposite = new Composite(composite, SWT.NONE);
columnComposite .setLayout(new GridLayout(2, false));
GridData gd2 = new GridData(SWT.LEFT, SWT.CENTER, false, false);
gd2.widthHint = 760;
gd2.heightHint = 240;
columnComposite .setLayoutData(gd1);

Here, im Using "widthHint" and heightHint which is not recommended as the whole layout will be ruined when the user decides to change the system font or resolution.

How do i achieve the same wihtout using widthhint and heightHint.

解决方案

Removed the widthHint and heightHint from both composites and updated grid data as: new GridData(SWT.FILL, SWT.FILL, true, true);

The GridLayout has taken care of width and height.
