本文综合了GridLayout、GridData、Composite以及Tree、TreeItem构造了一个比较复杂的应用例子。
/*---------- 构造代码 ---------*/

/*注意:80,代表*/

}

sc.setMinSize(size);
}

}
}
/*---------- 动作控制接口以及实现代码 --------*/
public interface ConfigSectionTest {
public Composite configSectionCreate(final Composite parent);
}
public class ModelConfigSection implements ConfigSectionTest {
public Composite configSectionCreate(Composite parent) {
GridData gridData;
GridLayout layout;
final Composite cMode = new Composite(parent,SWT.WRAP);
gridData = new GridData(GridData.HORIZONTAL_ALIGN_FILL|GridData.VERTICAL_ALIGN_FILL);
cMode.setLayoutData(gridData);
layout = new GridLayout();
layout.numColumns =4;
layout.marginHeight = 0;
cMode.setLayout(layout);
gridData = new GridData();
gridData.horizontalSpan = 4;
final Group gRadio = new Group(cMode, SWT.WRAP);
gRadio.setText("用户熟练程度");
gRadio.setLayoutData(gridData);
gRadio.setLayout(new RowLayout(SWT.HORIZONTAL));
Button button0 = new Button (gRadio, SWT.RADIO);
button0.setText("初级");
Button button1 = new Button (gRadio, SWT.RADIO);
button1.setText("中级");
Button button2 = new Button (gRadio, SWT.RADIO);
button2.setText("高级");
button0.setSelection(true);
gridData = new GridData(GridData.FILL_HORIZONTAL);
final Label label = new Label(cMode, SWT.WRAP);
gridData.horizontalSpan = 4;
label.setLayoutData(gridData);
label.setText("什么玩意!");
return cMode;
}
}
/*----------- 测试代码 ----------------*/
public class GridLayoutTest {
public static void main(String[] args){
GridLayoutObject obj = new GridLayoutObject();
obj.buildLayout();
}
}
运行结果:
