是否可以确定Bookmark何时包含TextTable？我曾考虑过通过XTextRange对象进行查看，但是该文档未指定任何有关比较范围的内容。
最佳答案
因此，从以下代码开始：
XBookmarksSupplier xBookmarksSupplier =
(XBookmarksSupplier)UnoRuntime.queryInterface(
XBookmarksSupplier.class, xComponent);
XNameAccess xNamedBookmarks = xBookmarksSupplier.getBookmarks();
Object bookmark = xNamedBookmarks.getByName("TextAndTable");
XTextContent xBookmarkContent = (XTextContent)UnoRuntime.queryInterface(
XTextContent.class, bookmark);
XTextRange xTextRange = xBookmarkContent.getAnchor();
听起来您正在询问如何确定在
xTextRange指定的范围内是否存在一个或多个文本表。为此，通常使用View Cursor。它很慢，但是普通的文本光标不能遍历不同的文本对象，因此如果该范围内有文本表或其他对象，它将失败。
这是我的Python类，也许您可以适应Java：
def differentPlaces(oCurs1, oCurs2):
"""Test using compareRegion to see if two cursors are in different places.
If compareRegion fails, such as after a nested table, return False.
"""
try:
oText = oCurs1.getText()
return oText.compareRegionEnds(oCurs1, oCurs2) != 0
except IllegalArgumentException:
logger.info("Could not compare region.")
return False
class RangeCompare:
"""Compare the viewcursor to a text range (a location).
Can be useful when traversing a cursor over a range.
The range is expected not to be modified.
"""
def __init__(self, rangeEnd, viewCursor):
self.oVC = viewCursor
self.rangeEnd = rangeEnd
self.endX = -1
self.endY = -1
def getCoords(self):
if self.endY > -1:
return
# remember where we were, because we'll need to use the viewcursor
originalVC = self.oVC.getText().createTextCursorByRange(self.oVC)
self.oVC.gotoRange(self.rangeEnd, False)
self.endX = self.oVC.getPosition().X
self.endY = self.oVC.getPosition().Y
self.oVC.gotoRange(originalVC, False)
def compareVC(self):
"""Compare the viewcursor to the range.
Assume we are travelling with the viewcursor.
See if it is up to the end yet or not.
The comparison is done by checking the physical position of the cursor.
Returns -1 if the VC location is less than self.rangeEnd, 0 if it is
the same, and 1 if it is greater.
Returns -2 if they are on the same line but not in the same spot, and
it's not certain which location is greater.
"""
self.getCoords()
curX = self.oVC.getPosition().X
curY = self.oVC.getPosition().Y
if curY < self.endY:
logger.debug("%d < %d", curY, self.endY)
return -1
elif curY > self.endY:
logger.debug("%d > %d", curY, self.endY)
return 1
elif curY == self.endY:
if curX == self.endX:
if differentPlaces(self.oVC, self.rangeEnd):
# There is probably a word-final diacritic that doesn't
# change the position, so we're not to the end yet.
logger.debug("Including word-final diacritic.")
return -2
# We're at the end.
logger.debug(
"VC same loc as text range (%d, %d).", curX, curY)
return 0
else:
logger.debug("Probably haven't gone far enough.")
return -2
用
rangeCompare = RangeCompare(xTextRange.getEnd(), xViewCursor)之类实例化该类。将视图光标移到
xTextRange的开头。然后继续循环调用xViewCursor.goRight(1, False)。每次检查光标是否位于TextTable中。 rangeCompare.compareVC() > 0时停止。
