我想在A面中的複合材料中放置3個固定尺寸的組。我想放置這個組的圖像和標籤中間。我的示例圖像和代碼如下。問題在於組的大小是根據標籤大小調整的,標籤寫在組的頂部,但我希望地方組的大小相同,以覆蓋A邊的寬度,標籤應該垂直居中。如何在SWT中設計複合材料
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(),
"D:\\projects\\ATMGW_SW\\Code\\atmgw-client\\icons\\in_arrow.png");
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(),
"D:\\projects\\ATMGW_SW\\Code\\atmgw-client\\icons\\out_arrow.png");
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(),
"D:\\projects\\ATMGW_SW\\Code\\atmgw-client\\icons\\error.png");
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);
}
您可能想嘗試[WindowBuilder Pro](http://www.eclipse。 org/windowbuilder /) – Kai
您正在泄漏圖像和字體。如果您創建圖像或字體,則必須安排它在不再需要時進行處理。也不要多次創建相同的字體,這是浪費內存。 –
謝謝greg-449和user714965,我再次修復了我的字體定義,WindowBuilder Pro可能很有用,但我不想使用生成的代碼。我更喜歡寫我自己的代碼。 – selentoptas
