Code Completion in UI classes

[ChrisW67]

G'day All,

Is there some trick to having Creator (1.1 on Linux, Qt 4.5.1) do code completion for Designer UI? Currently I get no useful completion after entering "m_ui->" with code straight from the Creator/Designer wizard (example below). I'm fairly sure this has worked in the past.

Cheers,
Chris

    explicit AlarmView(QWidget *parent = 0);
    virtual ~AlarmView();

Try to compile it, and then you should have the completion features.

[ChrisW67]

Thanks.

It was compiled on Gentoo and, for the most part, the completion works. Just the circumstances described above seem to break it. I've just done a quick rebuild to make sure that there were no broken deps. No change.

Is there a cache of information that might be corrupt or need rebuilding?

This file is auto generated from your .ui file. QtCreator doesn't have the current state of the file until it's compiled. So if you need autocompletion and make a change in the ui, you need to build again before you can use it.

[ChrisW67]

Thanks.

I've built the example code (and lots of other examples) many times, no change
It is not that it is not completing recent changes in the UI: it's not completing anything in the UI. The only thing in the completion drop-down is class "AlarmView" (from the Ui namespace) despite there being a QPushButton and QTableWidget in the UI.

I have a separate build directory that ends up containing the ui_*.h files and other intermediates. Perhaps that is causing an issue. I'll do a quick experiment with everything in one directory.

WOOHOO! It works if all is in one directory, but not if split.

My pro file looks like:

Is there something I should tweak here? I've tried adding the build directory to INCLUDEPATH and VPATH: no dice.
