我正在研究通过UNO与OpenOffice(swriter)进行交互的Java API。
对于TextTable,我很难设置TableColumn的“ OptimalWidth”属性。
我已经尝试了以下代码,似乎getColumns()方法无法将我带到TableColumn的属性,而只能插入和删除列。
XTableColumns xColumns = xTextTable.getColumns();
XIndexAccess xIndexAccess = (XIndexAccess) UnoRuntime.queryInterface(
XIndexAccess.class, xColumns);
for (int i = 0; i < xIndexAccess.getCount(); i++) {
XPropertySet xColumnProps = (XPropertySet) UnoRuntime
.queryInterface(XPropertySet.class,
(Any) xIndexAccess.getByIndex(i));
if (xColumnProps != null) {
xColumn.setPropertyValue("OptimalWidth", new Boolean(true));
}
}
谁能帮我或给我一些技巧来设置表格的OptimalWidth属性?
提前非常感谢您!
最佳答案
找出这是一段艰难的旅程,但我最终设法创建了一个功能完全符合此要求的功能:
private void optimizeTableColumnWidths(XTextTable table)
throws Exception
{
XTextViewCursorSupplier cursorSupplier = (XTextViewCursorSupplier)
UnoRuntime.queryInterface(XTextViewCursorSupplier.class,
document.getCurrentController());
XTextViewCursor viewCursor = cursorSupplier.getViewCursor();
String cellName = "A1";
XText cellText = (XText)UnoRuntime.queryInterface(
XText.class, table.getCellByName(cellName));
XTextCursor cursor = cellText.createTextCursor();
viewCursor.gotoRange(cursor, false);
viewCursor.gotoEnd(true);
viewCursor.gotoEnd(true);
XController controller = document.getCurrentController();
XFrame frame = controller.getFrame();
XDispatchProvider dispatchProvider = (XDispatchProvider)
UnoRuntime.queryInterface(XDispatchProvider.class, frame);
String unoAction = ".uno:SetOptimalColumnWidth";
String targetFrameName = "";
int searchFlags = 0;
PropertyValue[] properties = new PropertyValue[0];
dispatchHelper.executeDispatch(
dispatchProvider,
unoAction,
targetFrameName,
searchFlags,
properties);
}
重要的是,dispatchHelper来自OpenOffice上下文,而不是当前文档。我通过这种方式检索dispatchHelper:
XComponentContext context = Bootstrap.bootstrap();
XMultiComponentFactory factory =
context.getServiceManager();
Object dispatchHelperObject = factory.createInstanceWithContext(
"com.sun.star.frame.DispatchHelper", ooContext);
this.dispatchHelper = (XDispatchHelper)UnoRuntime.queryInterface(
XDispatchHelper.class, dispatchHelperObject);
