我想将3个固定大小的组放在A边的合成物中。我想将图像和标签放置在该组的中间。我的示例图像和代码如下。问题是要根据组中的标签大小调整组的大小,并将标签写在组的顶部,但是我希望将位置组的大小固定为相等,以覆盖A边的宽度,并且标签应垂直于组的中间。
private void designComposite() {
Section sectionA = toolkit.createSection(form.getBody(), Section.TITLE_BAR);
sectionA.setText("A");
Composite sectionClientA = toolkit.createComposite(sectionA);
sectionClientA.setLayout(new RowLayout());
Composite dynamicDataComp = toolkit.createComposite(sectionClientA);
dynamicDataComp.setLayout(new RowLayout());
Group group_incom = new Group(dynamicDataComp, SWT.NONE);
group_incom.setLayout(new RowLayout());
Label lbl_img_incom = new Label(group_incom, SWT.CENTER);
Image img_incom = new Image(lbl_img_incom.getDisplay(),
"<path>");
lbl_img_incom.setImage(img_incom);
group_incom.setText("# of Incoming Messages :");
Label lbl_incomMsg = toolkit.createLabel(group_incom, "99", SWT.CENTER | SWT.VERTICAL);
Font incomFont = new Font(lbl_incomMsg.getDisplay(), new FontData("Arial", 12, SWT.BOLD));
lbl_incomMsg.setFont(incomFont);
lbl_incomMsg.pack();
Group group_outgo = new Group(dynamicDataComp, SWT.NONE);
group_outgo.setLayout(new RowLayout());
Label lbl_img_outgo = new Label(group_outgo, SWT.CENTER);
Image img_outgo = new Image(lbl_img_outgo.getDisplay(),
"<path>");
lbl_img_outgo.setImage(img_outgo);
group_outgo.setText("# of Outgoing Messages :");
Label lbl_outgoMsg = toolkit.createLabel(group_outgo, "145639612", SWT.CENTER);
Font outgoFont = new Font(lbl_outgoMsg.getDisplay(), new FontData("Arial", 13, SWT.BOLD));
lbl_outgoMsg.setFont(outgoFont);
lbl_outgoMsg.pack();
Group group_error = new Group(dynamicDataComp, SWT.NONE);
group_error.setLayout(new RowLayout());
Label lbl_img_error = new Label(group_error, SWT.CENTER);
Image img_error = new Image(lbl_img_error.getDisplay(),
"<path>");
lbl_img_error.setImage(img_error);
group_error.setText("# of Error Messages :");
Label lbl_errorMsg = toolkit.createLabel(group_error, "345", SWT.CENTER);
Font errorFont = new Font(lbl_errorMsg.getDisplay(), new FontData("Arial", 13, SWT.BOLD));
lbl_errorMsg.setFont(errorFont);
lbl_errorMsg.pack();
sectionA.setClient(sectionClientA);
}
使用GridLayout
并将列设置为相等的宽度:
Composite dynamicDataComp = new Composite(parent, SWT.NONE);
dynamicDataComp.setLayout(new GridLayout(3, true));
dynamicDataComp.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, true, false, 1, 1));
Group group_incom = new Group(dynamicDataComp, SWT.NONE);
group_incom.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, true, false, 1, 1));
group_incom.setLayout(new RowLayout());
//...
一种方法是将GridLayout
用于父组合,并告诉它使用3个相等大小的列:
Composite dynamicDataComp = toolkit.createComposite(sectionClientA);
dynamicDataComp.setLayout(new GridLayout(3, true));
