[SOLVED] Reading MS Word in Qt, please!
-
Hey there, I am both new to Qt and do not have much experience in C++. I need to make program which opens .docx file and gets text and table contents from it to process it later; I managed to show document contents in TextEdit widget though. I looked through quite a lot of posts but still don't get it. I both open document and display it in a widget with this piece of code:
@
QAxWidget* WordDoc=new QAxWidget ("Word.Document", this-> ui-> textEdit);
WordDoc->setGeometry (QRect (10, 10, 761, 511));
WordDoc->setControl (filename.join(""));
WordDoc->show();
@, where "filename" is QStringList variable. I figured out that I need to use querySubObject() and dynamicCall() functions which take COM object's specific methods as parameters, but I can't understand how to find a full list of MS Word's - compatible methods. I've tried to generate documentation by WordDoc->generateDocumentation() function which gave me list of some signals, slots, parameters, functions etc, but I did not seem to find anything I needed. So can anyone explain how do I use querySubObject and preferably some code example to get hang of it? Thanks in advance!

Thanks, and I finally managed to get things work.
Here's some info to help people like me to understand a few basic things:querySubObject() function is used to navigate through MS Word's or other COM object's object model tree. Such tree for MS Word can be found here: http://msdn.microsoft.com/en-us/library/aa220474(v=office.10).aspx
dynamicCall() function is used to call object's specific methods. Documentation for specific object type can be generated via code
@ui->textEdit->setText(object_name->generateDocumentation());@
Details for every method and whatnot can be found in Microsofts VBA documentation: http://www.microsoft.com/en-us/download/details.aspx?id=40326
Note that for every sub object different documentation is generated.And here's part of code which opens up .docx document that contains text only and prints its contents to textEdit:
@QAxObject wordApplication = new QAxObject("Word.Application", this);
QAxObject documents = wordApplication->querySubObject("Documents");
QAxObject document = documents->querySubObject("Open(const QString&, bool)", "C:\Blah\Blah\Blah\Microsoft Word.docx", true);
QAxObject words = document->querySubObject("Words");
QString textResult;
int countWord = words->dynamicCall("Count()").toInt();
for (int a = 1; a <= countWord; a++){
textResult.append(words->querySubObject("Item(int)", a)->dynamicCall("Text()").toString());
}
ui->textEdit->setText(textResult);@Now, I hope, you got the basics of working with COM objects. Good luck!

Nice !
Thanks for sharing your newly acquired knowledge ! :)
Can you also update the thread title prepending [solved] ? So other forum users may know a solution has been found :)
