The writer already exist on qt version 4.5 having small bug..
1- writing draw:frame tag (image tag) inside text:span and not on text

(block tag)
2- it not write pagezise info on style head or page margin default

I start to write a reader today code on:
Only QT4.5
http://ppk.ciz.ch/MiniScribus/TextOdfDebug.1.zip

Only table is not ready why?
i suppose a bug on QT4.5
qtable->mergeCells(gorow,gocool,qAbs(cr - 1),qAbs(cs - 1));
mergeCell can not merge all column from one line if i leave -1
qtable->mergeCells(gorow,gocool,cr,cs);
it not merge cell can anybody try it to find bug on qt 4.5

or can any body confirm a bug on mergeCells?

QTextTable *qtable = cur.insertTable(rowCounter,constraints.size(),tf);

I solved :-)

/* value must having min 1 or row or int 3-4 not automatic accept 0 */

Qt Code:

QDomElement oocell = oorow.firstChildElement("table:table-cell");
     while (!oocell.isNull())  {
       gocool++;
        const QTextTableCell ctd = qtable->cellAt(gorow,gocool);
         const int cr = qMax(oocell.attribute("table:number-rows-spanned").toInt(),0);
         const int cs = qMax(oocell.attribute("table:number-columns-spanned").toInt(),0);
        if (qMax(cs,cr) !=0) {
        /* value must having min 1  or row or cell */
         qtable->mergeCells(gorow,gocool,qMax(cr,1),qMax(cs,1));

         cell = qtable->cellAt(gorow,gocool);

Which qt snapshot are you using? I tried to compile 3 snapshots but all of them was buggy and didn't able to compile.

If you use mingw ... replace the mingw/ path and take the mingw from trolltech mirror.
ftp://ftp.trolltech.com/qt/source/qt....4.1-mingw.exe
Take only the compiler... i suppose it have a patch.... i am not sure.

Only append utlis and minimal sys from self.

From my 10 mounth old mingw install i found compiler error. after i replace the new mingw + window service pack 3 all running easy....

snapshots i install :

my mysql is on mingw lib path... and mysql running without plug-in

One from 6 day a go , other from 20080913 i build static.

Can you help me to write last piece (table) from odt reader?
svn http://fop-miniscribus.googlecode.co.../TextOdfDebug/

OOReader.h
OOReader.cpp

I not find difference from a table writteln by openOffice and from QT4.5

My reader can draw table from openOffice odt but not from QT4.5..

If you dont have qt4.5 to test:
i build static /qt4.5_st/demos/textedit/ it save *odt Open Document format
it can only save odt file http://ppk.ciz.ch/MiniScribus/odt/

and i like to test xslt speed.. from 4.5

I have the latest mingw too, but my mingw can't compile snapshots.

Sure, if i can (and have enough time), i will help you. But I didn't understand you, you can't create a table by using Qt Tools?

Have you Service Pack3 on window XP or you use vista?
try to build only:
./configure bla bla..
make sub-src
[only core lib]
not make all demo designer and tool designer, build at end designer & tool

Read table from OpenOffice odt file is ok and working..

Read table from QT4.5 odt file (file created by qt) not working..

I have now my OpenDocument reader its possibel to build on qt4.4.1 or > on 4.5 reader already exist...

Only the listformat tree it show the first level table col-span and row-span are perfect...
And and one QTextEdit, if You load 30 or more page prepare you mind to wait long time.

I save source on SVN:
