Porting old code to Qt4

ckluss

Hi,

I want to use old Qt code with Qt4 (because of Qt3Support). But the following code does not compile

@QMetaData *slot_tbl = QMetaObject::new_metadata(1);
QMetaData::Access *slot_tbl_access = QMetaObject::new_metaaccess(1);
slot_tbl[0].name = "slotRepositionText()";
slot_tbl[0].ptr = (QMember)ov1_0;
slot_tbl_access[0] = QMetaData::Public;@

Can you give me a hint how to fix this?

thx
Christof

Hi and welcome to devnet,

Where does that code come from ?

andre

Looks like auto-generated code to me?

SGaist

Looks also like it to me, that's why I wanted to know it's origin. It would be strange getting wrong code from moc even while porting.

Hi,

thx for the fast reply. I want port the following code (from 2004) (Modelling Software) to Qt 4 (because of Qt3Support... otherwise Qt 5 :( )

That is indeed a generated file. No need to port it manually, it (or something like it with the same functionality) will be created for you automatically.

In addition to what Andre said, you should also remove all moc files from your source tree.

many thanks again. It is not my source tree, but I'm trying to convince the maintainer

In general: don't put generated files in a source repository. That includes the moc_.cpp files, but also ui_.h and qrc_*.cpp files, besides all that is created by the non-qt parts of your toolchain of course.
