在java中，SWT组合不会根据设置的布局进行布局

Composite composite = new Composite(parent, SWT.NONE);
composite.setLayout(new GridLayout(2, false)); // 2列的网格布局

Label label1 = new Label(composite, SWT.NONE);
label1.setText("Label 1");

Text text1 = new Text(composite, SWT.BORDER);
text1.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, true, false)); // 设置控件在网格中的位置和大小

Composite composite = new Composite(parent, SWT.NONE);
composite.setLayout(new FillLayout(SWT.VERTICAL)); // 垂直排列控件

Button button1 = new Button(composite, SWT.PUSH);
button1.setText("Button 1");

Button button2 = new Button(composite, SWT.PUSH);
button2.setText("Button 2");

Composite composite = new Composite(parent, SWT.NONE);
RowLayout rowLayout = new RowLayout(SWT.HORIZONTAL);
rowLayout.spacing = 10; // 设置控件之间的间距
rowLayout.pack = false; // 控件不自动调整大小
composite.setLayout(rowLayout);

Label label1 = new Label(composite, SWT.NONE);
label1.setText("Label 1");

Text text1 = new Text(composite, SWT.BORDER);
text1.setLayoutData(new RowData(100, SWT.DEFAULT)); // 设置控件的大小
