Qt autocomplete in deep nested structs

[Deepfreeze]

Hello,

I really like how in Qt Creator the autocomplete window opens to show which
attributes are available. In this way I can easily select the correction function,
variable, enumerate or class.

I've seen that this stops at a certain depth of the data structure. In example when
using PCL. I can ask the x-coordinate of a point using:
@cloud->point[10].x@

Now the autocompletion helps with all steps.

But when I place this cloud in another struct or container, the '.x' part won't show
anymore.

Does anybody know how to solve this?

It may happen if header file for an intermediate member is not included.
Or you may found a bug in QtCreator.

Could you post simple example that reproduce the problem.

For example this code works for me. Each dot triggered an autocomplete.
@
struct ExternalCloud
{
struct Cloud
{
QVector<QWidget> widgets;
};
Cloud m_cloud;
};

MainWindow::MainWindow(QWidget *parent)
: QMainWindow(parent)
{
ExternalCloud extCloud;
extCloud.m_cloud.widgets[1].childAt(10, 10)->cursor().pos().isNull();
}

Thanks for checking it with that example.

In your example it stops at widgets[1 ]. If I type a dot it doesn't give any autocomplete. I have the same when using a std::vector< >.

I have Qt Creator 3.1.2, Qt 5.3.1 on Windows 8.1 with msvc2013 x64.

It stops on std::vector for me too if I use QtCreator built-in C++ model.
It works if I use Clang C++ model.

You can select a C++ Code model in "Options/C++/Code Model"
But I don't know if Clang model is available on Windows.

I suggest to open a bug report "Qt Bug Tracker":https://bugreports.qt-project.org/

Hi, the Clang model is available. I have tried it before this question on the forum and just tested it again. But it doesn't work.

Thanks for you help. I will open a bug report.
