DiagramPrefsDialog Class Reference

Detailed Description

A dialog that allows for setting preferences for a requested diagram.

A dialog that allows for setting preferences for a requested diagram. Note: In the current version this dialog only works when requesting data from a database. Visualisation of data from an ASCII-file is still possible using the "Load File"-button but setting the preferences will not work (i.e. it is only possible to visualise all the data in the file with default preferences.

Constructor & Destructor Documentation

DiagramPrefsDialog() [1/3]

DiagramPrefsDialog::DiagramPrefsDialog	(	const GeoLib::Station *	stn,
		const QString &	listName,
		QDialog *	parent = nullptr )

Opens a new dialog based on station and the list this station belongs to. If a database connection is available, the program will try to find data associated with the station, otherwise data can be loaded from a file.

Parameters

stn	The station object associated the diagram.
listName	The station list the station belongs to.
parent	The parent QDialog.

Definition at line 16 of file DiagramPrefsDialog.cpp.

    : QDialog(parent), _window(nullptr)
{
    setAttribute(Qt::WA_DeleteOnClose);
 
    setupUi(this);
    stationNameLabel->setText(QString::fromStdString(stn->getName()));
    stationTypeLabel->setText(listName);
}

References _window, and GeoLib::Station::getName().

DiagramPrefsDialog() [2/3]

DiagramPrefsDialog::DiagramPrefsDialog ( GeoLib::Station * stn, QDialog * parent = nullptr )

explicit

Opens a new dialog and automatically reads data from the associated station object.

Parameters

stn	The station object associated the diagram.
parent	The parent QDialog.

Definition at line 29 of file DiagramPrefsDialog.cpp.

    : QDialog(parent), _window(nullptr)
{
    setupUi(this);
    stationNameLabel->setText(QString::fromStdString(stn->getName()));
    stationTypeLabel->setText("");
    DiagramList::readList(stn->getSensorData(), _list);
 
    fromDateLine->setText(
        QString::number(stn->getSensorData()->getStartTime()));
    toDateLine->setText(QString::number(stn->getSensorData()->getEndTime()));
    this->createVisibilityCheckboxes();
}

DiagramPrefsDialog() [3/3]

DiagramPrefsDialog::DiagramPrefsDialog ( const QString & filename, DetailWindow * window = nullptr, QDialog * parent = nullptr )

explicit

Opens a new dialog and automatically reads data from the specified file. The diagram is not associated with any geometric object.

Parameters

	filename	File containing data for the diagram(s) to be visualised.
[out]	window	Returns the created DetailWindow.
	parent	The parent QDialog.

Definition at line 43 of file DiagramPrefsDialog.cpp.

createVisibilityCheckboxes()

void DiagramPrefsDialog::createVisibilityCheckboxes ( )

private

Creates checkboxes for every list of data values found. Per default all of these are checked, i.e. all diagrams will be visualised. Any checkbox the user unchecks will result in the associated data not being visualised.

Definition at line 175 of file DiagramPrefsDialog.cpp.

    {
        QCheckBox* box = new QCheckBox(item->getName());
        box->setChecked(true);
        this->CheckBoxLayout->addWidget(box);
        _visability.push_back(box);
    }
}
