]]>SWT GridLayout 网格布局http://www.blogjava.net/brucejini/archive/2009/07/20/287465.html[terry][terry]Mon, 20 Jul 2009 06:12:00 GMThttp://www.blogjava.net/brucejini/archive/2009/07/20/287465.htmlhttp://www.blogjava.net/brucejini/comments/287465.htmlhttp://www.blogjava.net/brucejini/archive/2009/07/20/287465.html#Feedback0http://www.blogjava.net/brucejini/comments/commentRss/287465.htmlhttp://www.blogjava.net/brucejini/services/trackbacks/287465.html
GridLayout的构造函数 
构造函数描述 
public GridLayout()建立一个默认的GridLayout布局. 
public GridLayout(int numColumns, boolean makeColumnsEqualWidth)建立一个GridLayout布局,拥有numColumns列,如果makeColumnsEqualWidth为true,则全部组件将拥有相同的宽度. 
GridLayout有6个公共的数据成员,相对重要的是numColumns. 

GridLayout数据成员 
属性描述 
int horizontalSpacing控制一行中两个网格间组件的宽度,像素为单位. 
boolean makeColumnsEqualWidth如果为true,强制全部的列拥有相同的宽度. 
int marginHeight控制顶部和底部组件离边缘的距离空间,以像素为单位. 
int marginWidth控制左边和右边组件离边缘的距离空间,以像素为单位. 
int numColumns此GridLayout的列数目. 
int verticalSpacing控制一列中两个网络间组件的宽度,像素为单位. 
你能使用GridLayout设置GridData类来布局更多的复杂组件.GridData有两个构造函数. 

GridData构造函数 
构造函数描述 
public GridData()创建默认一个默认的GridData对象. 
public GridData(int style)初始化指定的style风格布局. 
和其它的布局类一样,GridLayout也提供一些公共的数据成员控制它的状态,它也提供一些常量,你可以在在构造成函数中使用.你可以用过位标志"|"来连接几个不同的效果,但请注意风格不要起冲突. 

GridData数据成员 
属性描述 
boolean grabExcessHorizontalSpace如果为true,指示布局器中网格自动填充多余的水平空间,默认为false. 
boolean grabExcessVerticalSpace如果为true,指示布局器中网格自动填写多余的垂直空间,默认为false. 
int heightHint该行中最小的高度,以像素为单位,默认为SWT.DEFAULT. 
int horizontalAlignment网格中组件水平对齐方式,可能的值为BEGINNING, CENTER, END,和FILL. 
int horizontalIndent与左边网格的水平缩进,默认为0 
int horizontalSpan设置网格占有的列数目,默认为1 
int verticalAlignment网格中组件垂直对齐方式,可能的值为BEGINNING, CENTER, END,和FILL. 
int verticalSpan设置网格占有的行数目,默认为1 
int widthHint该列中最小的宽度,以像素为单位,默认为SWT.DEFAULT. 

GridData常量 
常量描述 
BEGINNING非style值,指定水平或垂直的对齐方式. 
CENTER非style值,指定组件在网格中居中,水平或垂直. 
END非style值,指定水平或垂直的对齐方式. 
FILL非style值,指定组件填充网格,水平或垂直. 
FILL_BOTH设置horizontalAlignment和verticalAlignment为FILL,设置grabExcessHorizontalSpace和grabExcessVerticalSpace为true. 
FILL_HORIZONTAL设置horizontalAlignment为FILL,和设置grabExcessHorizontalSpace为true. 
FILL_VERTICAL设置verticalAlignment为FILL,和设置grabExcessVerticalSpace为true. 
GRAB_HORIZONTAL设置grabExcessHorizontalSpace为true. 
GRAB_VERTICAL设置grabExcessVerticalSpace为true. 
HORIZONTAL_ALIGN_BEGINNING设置horizontalAlignment为BEGINNING. 
HORIZONTAL_ALIGN_CENTER设置horizontalAlignment为CENTER. 
HORIZONTAL_ALIGN_END设置horizontalAlignment为END. 
HORIZONTAL_ALIGN_FILL设置horizontalAlignment为FILL. 
VERTICAL_ALIGN_BEGINNING设置verticalAlignment为BEGINNING. 
VERTICAL_ALIGN_CENTER设置verticalAlignment为CENTER. 
VERTICAL_ALIGN_END设置verticalAlignment为END. 
VERTICAL_ALIGN_FILL设置verticalAlignment为FILL. 

下面我们来看几个例子： 
代码片段： 

GridLayout gridLayout = new GridLayout(); 
gridLayout.numColumns = 2; 
shell.setLayout(gridLayout); 

new Button(shell, SWT.PUSH).setText("one"); 
new Button(shell, SWT.PUSH).setText("two"); 
new Button(shell, SWT.PUSH).setText("three"); 
new Button(shell, SWT.PUSH).setText("four");运行效果： 


图中可以看到各个Button的宽度是依靠字体长度来自动设定的，假如你想设置所有的Button都使用相同的大小该怎么办？使用makeColumnsEqualWidth = true;吗？不，这样做不行，它回会将各网格的大小设为相同,我们该使用GridData中相关属性来设置Button.下面程序中使用了GridData.FILL_BOTH属性,它将填充所在网格水平或垂直空间,并将多余空间占有,这样不论窗口调整多大,四个Button都会有相同空间. 
当然GridLayout能做的不只是这些,要更复杂的效果,可能多个Composite配合使用,具体请参见原书第二部分第四章:Apress.The.Definitive.Guide.to.SWT.and.JFace.eBook-LiB.chm 
运行效果 
初始化: 

调整大小后: 

完整代码:
