how to auto break or warp text line in table cell? about hwplib

[neolord0]

Hangul supports Text Wrapping by LineChange property in ListHeaderForTextBox Object.
The value of this attribute can be obtained as follows.

Section s = hwpFile.getBodyText().getSectionList().get(0);
Paragraph firstParagraph = s.getParagraph(0);
ControlRectangle rect = (ControlRectangle) firstParagraph.getControlList().get(2);
System.out.println(rect.getTextBox().getListHeader().getProperty().getLineChange());

If This property value is Normal, Texts have warpped.

And, I think LineSeqItem seems to store a pre-calculated value to draw a Hangul file quickly.
The text is drawn well without the LineSeqItem, except for the text line's space function.

LineSeqItem.textStartPosition is the text start position of the line represented by LineSeqItem in the full text of the paragraph. The figure above shows that the second line starts at index 2( zero-based).

ok, i find the cell's listHeader also have the ListHeaderPropertyForCell same setLineChange method .
i check the property is Normal

the file open look like:

i'am not use the text box just use the cell for contain text.

maybe i should be send the .hwp file and code for you ?

[neolord0]

yes. I want you to send them.

[zuoliang0]

i test the text sure warped,but some word not show full

[zuoliang0]

i find the problem, when i set the ParaShape for Paragraph the cell content will be not warp.

                ParaShape paraShape = hwpFile.getDocInfo().addNewParaShape();
		paraShape.getProperty1().setAlignment(Alignment.Left);
		int id = hwpFile.getDocInfo().getParaShapeList().size() - 1;
		ph.setParaShapeId(id);

but i don't know how fix it,
the new code has send for you mail.

hello ，do you receive my email? if you have any question you can give me feedback.
thank you

According to my testing, we need a LineSegItem object for each line segmented for text-wrapping. However, the value of the TextStartPositon property in the LineSegItem object is hard to compute. So, I did not create any LineSegItem objects. And I set the value of the LineSpace property on the ParaShape object that is not in your code.

If you save this file again from Hangul, LineSegItem is automatically created.
Look at my attachment.

thank you.
i try you code ,it's work for auto text-wrapping.

you say

the TextStartPositon property in the LineSegItem object is hard to compute

it mean if i need set text wrapping by hand then must be compute the LineSegItem's TextStartPositon property ?

[zuoliang0]

in my program i'm use the \n to mark break line,
so i just easy compute the postion.

this is my code:

private  void setLineBreak(String text,Paragraph firstParagraph, int width){
        ParaLineSeg lineSeg = firstParagraph.getLineSeg();
        if (text.contains("\n")) {
            int i =-1;
                while ((i=text.indexOf("\n", i+1 ))!=-1){
                LineSegItem lineSegItem = lineSeg.addNewLineSegItem();
                lineSegItem.setTextPartHeight(1000);
                lineSegItem.setStartPositionFromColumn(0);
                lineSegItem.setDistanceBaseLineToLineVerticalPosition(850);
                lineSegItem.setLineSpace(100);
                lineSegItem.setSegmentWidth(width);
                lineSegItem.setTextStartPositon(i);
                lineSegItem.getTag().setFirstSegmentAtLine(true);
                lineSegItem.getTag().setLastSegmentAtLine(true);
            }
        }

    }

thank you for you answer.

if you receive any donate, i wish do it.
such as digital cash: eth or bitcoin ete.

In principle, the value of LineSegItem's TextStartPositon is the start of the string in a line break. If the string "ABCD EDFG" is divided as follows
ABCD
EDFG
Two LineSegItems are required, and TextStartPositon values must be set to 0 and 5, respectively.
Typical word processing programs do not need this value, but Hangul seems to be needed for quick drawing. To get the TextStartPositon value, you should actually draw the all paragraph attribute and the all character attribute on the string. It's awkward until you know well about word processor programming.

And your contribution will be appreciated.
I get my first donation. Thank you for giving me this experience.
