Wrong open dialog default directory

[midenok]

When no files opened in project, open dialog points to some previous directory from another session.

Reproduce 1

1. Close all files in session, restart.
2. In started session select project.
3. Press Ctrl+O

Reproduce 2

1. Start new file.
2. Press Ctrl+O

Result

Open file dialog points to some arbitrary location.

Expected

Dialog points to location of selected project or its item.

• save dialog also must be fixed
• if focus is on projectTreeView then it must take precedence over opened file

KDevelop::DocumentControllerPrivate::showOpenFile() dir logic

    OpenFileResult showOpenFile() const
    {
        QUrl dir;
        if ( controller->activeDocument() ) {
            dir = controller->activeDocument()->url().adjusted(QUrl::RemoveFilename);
        } else  {
            const auto cfg = KSharedConfig::openConfig()->group("Open File");
            dir = cfg.readEntry( "Last Open File Directory", Core::self()->projectController()->projectsBaseDirectory() );
        }

QUrl ProjectController::projectsBaseDirectory() const
{
    KConfigGroup group = ICore::self()->activeSession()->config()->group( "Project Manager" );
    return group.readEntry( "Projects Base Directory", QUrl::fromLocalFile( QDir::homePath() + "/projects" ) );
}

projectsBaseDirectory() doesn't look good... Have to get backtrace of Projects Toolview and try to figure out how to get dir of selected item from there.

Get path of project item

void ProjectTreeView::slotActivated( const QModelIndex &index )
{
    if ( QApplication::keyboardModifiers() & Qt::CTRL || QApplication::keyboardModifiers() & Qt::SHIFT ) {
        // Do not open file when Ctrl or Shift is pressed; that's for selection
        return;
    }
    KDevelop::ProjectBaseItem *item = index.data(ProjectModel::ProjectItemRole).value<ProjectBaseItem*>();
    if ( item && item->file() )
    {
        emit activate( item->file()->path() );
    }
}

[midenok]

Now we need to access ProjectTreeView from DocumentController(Private?).

It accessed like this: m_ui->projectTreeView:

    Ui::ProjectManagerView* m_ui;

ProjectManagerView::ProjectManagerView( ProjectManagerViewPlugin* plugin, QWidget *parent )
        : QWidget( parent ), m_ui(new Ui::ProjectManagerView), m_plugin(plugin)

./projectmanagerviewplugin.cpp:156:    core()->uiController()->addToolView( i18n("Projects"), d->factory );

Save file dialog also need to be adjusted.

From ToolView impossible to access ProjectManagerView or ProjectTreeView as it is simple QWidget.

[midenok]

As it seems impossible to access ProjectManagerView from anywhere else, should we react on signal?

void ProjectManagerView::selectionChanged()
{
    m_ui->buildSetView->selectionChanged();
    QList<ProjectBaseItem*> selected;
    foreach( const QModelIndex& idx, m_ui->projectTreeView->selectionModel()->selectedRows() )
    {
        selected << ICore::self()->projectController()->projectModel()->itemFromIndex(indexFromView( idx ));
    }
    selected.removeAll(nullptr);
    KDevelop::ICore::self()->selectionController()->updateSelection( new ProjectManagerViewItemContext( selected, this ) );
}
