Hello,
I am in the process of converting several Java LO programming examples to
Python. My plan is to do all (or most) of them. Also I try to extend them.
However I encountered some surprises.
I converted LibreOffice4.4_SDK/examples/java/Text/GraphicsInserter.java which
inserts a graphic image in a new Writer document. Works without problems.
Then I decided to add some text also, and put the picture in the middle of the
text.
The code goes like this:
# Create a new Writer document, which will be automatically displayed
doc = Desktop.loadComponentFromURL("private:factory/swriter", "_blank", 0,
())
# Getting the text
xText = doc.getText()
# Getting a cursor on the document
xTextCursor = xText.createTextCursor()
# Inserting some text
xText.insertString(xTextCursor, "This is the first paragraph.", False)
xText.insertControlCharacter(xTextCursor, PARAGRAPH_BREAK, False)
xText.insertString(xTextCursor, "Some text before the graphic. ", False)
# Insert the graphic
insertGraphic(doc, xText, xTextCursor, sUrl)
# Inserting some more text
xText.insertString(xTextCursor, "Some text after the graphic.", False)
xText.insertControlCharacter(xTextCursor, PARAGRAPH_BREAK, False)
xText.insertString(xTextCursor, "This is the second paragraph.", False)
def insertGraphic(doc, xText, cursor, sUrl):
oGraphic = doc.createInstance("com.sun.star.text.TextGraphicObject")
xText.insertString(cursor, "++", False)
# Insert graphic between ++ and //
xText.insertTextContent(cursor, oGraphic, False)
# Setting the anchor type - must be done first, otherwise the graphic will
be put after the //
oGraphic.AnchorType = AS_CHARACTER
xText.insertString(cursor, "//", False)
# Setting the graphic url
oGraphic.GraphicURL = sUrl
# Setting the width and height
oGraphic.Width = 2000
oGraphic.Height = 2000
The image is inserted in the middle of a paragraph and surrounded by ++ and //
to indicate where it should be. This also works without problems.
Then I decided to change the order. First I insert all text; then I go back to
the insertion point and insert the image. To my surprise the image ended up a
couple of words later in the text
The insertion code is then:
# Inserting some text
xText.insertString(xTextCursor, "This is the first paragraph.", False)
xText.insertControlCharacter(xTextCursor, PARAGRAPH_BREAK, False)
xText.insertString(xTextCursor, "Some text before the graphic. ", False)
# Inserting some more text
xText.insertString(xTextCursor, "Some text after the graphic.", False)
xText.insertControlCharacter(xTextCursor, PARAGRAPH_BREAK, False)
xText.insertString(xTextCursor, "This is the second paragraph.", False)
# Move the cursor
xTextCursor.gotoPreviousParagraph(False)
xTextCursor.gotoNextSentence(False)
did you sure you are here where you think you are ? and not at the end
off the wro,g paragraph
trye
# Move the cursor xTextCursor.gotoPreviousParagraph(False)
xTextCursor.gotoPreviousParagraph(False)
xTextCursor.gotoNextSentence(False)
hope it helps
Fernand
# Insert the graphic
insertGraphic(doc, xText, xTextCursor, sUrl)
Now I would expect ++Image// to be found just before "Some text after the graphic."
However the ++// is indeed inserted there, but the image appears after "Some text after
the", 4 words later. The image is indeed anchored to this position, as I can see when I
manually insert some more text before it. So it is not a matter of an offset.
I have also tried to create another cursor with the endpoint of xTextCursor
between the two sentences, and then use this to insert the graphic but that
doesn't help.
Does anybody know what is happening here?
