Detailed Description

Windows in Stellarium are actually basic QWidgets that have to be wrapped in a QGraphicsProxyWidget (CustomProxy) to be displayed by StelMainView (which is derived from QGraphicsView). See the Qt documentation for details.

The base widget needs to be populated with controls in the implementation of the createDialogContent() function. This can be done either manually, or by using a .ui file. See the Qt documentation on using Qt Designer .ui files for details.

The createDialogContent() function itself is called automatically the first time setVisible() is called with "true".

Moving a window is done by dragging its title bar, defined in the BarFrame class. Every derived window class needs a BarFrame object - it has to be either included in a .ui file, or manually instantiated in createDialogContent().

The screen location of the StelDialog can be stored in config.ini. This requires setting dialogName (must be a unique name, should be set in the constructor), and setting a connect() from the BarFrame's movedTo() signal to handleMovedTo() in createDialogContent(). If the dialog is called and the stored location is off-screen, the dialog is shifted to become visible.

StelProperty and StelAction

The StelDialog base class provides multiple helper functions that allow easy two-way binding of widgets to specific StelAction or StelProperty instances. These functions are:

connectCheckBox to connect a StelAction to a QAbstractButton (includes QCheckBox)
connectIntProperty to connect a StelProperty to a QSpinBox or QComboBox
connectDoubleProperty to connect a StelProperty to a QDoubleSpinBox or QSlider
connectBoolProperty to connect a StelProperty to a QAbstractButton (includes QCheckBox) Take care that a valid property name is used and it represents a property that can be converted to the required data type, or the program will crash at runtime when the function is called

Member Function Documentation

◆ askColor

void StelDialog::askColor ( )

protectedslot

This QToolButton needs properties "propName" and "iniName" which should be prepared using connectColorButton().

◆ connectBoolProperty()

static void StelDialog::connectBoolProperty	(	QAbstractButton *	checkBox,
		const QString &	propName
	)

staticprotected

Warning: If the action with propName is invalid/unregistered, or cannot be converted to the required datatype, the application will crash

◆ connectColorButton()

void StelDialog::connectColorButton	(	QToolButton *	button,
		QString	propertyName,
		QString	iniName
	)

protected

Parameters

toolButton	the QToolButton which shows the color
propertyName	a StelProperty name which must represent a color (coded as Vec3f)
iniName	the associated entry for config.ini, in the form group/name. Usually "color/some_feature_name_color".

Warning: If the action with propName is invalid/unregistered, or cannot be converted to the required datatype, the application will crash

◆ connectDoubleProperty() [1/2]

static void StelDialog::connectDoubleProperty	(	QDoubleSpinBox *	spinBox,
		const QString &	propName
	)

staticprotected

Warning: If the action with propName is invalid/unregistered, or cannot be converted to the required datatype, the application will crash

◆ connectDoubleProperty() [2/2]

static void StelDialog::connectDoubleProperty	(	QSlider *	slider,
		const QString &	propName,
		double	minValue,
		double	maxValue
	)

staticprotected

Parameters

slider	The slider which should be connected
propName	The id of the StelProperty which should be connected
minValue	the double value associated with the minimal slider position
maxValue	the double value associated with the maximal slider position

Warning: If the action with propName is invalid/unregistered, or cannot be converted to the required datatype, the application will crash

◆ connectIntProperty() [1/4]

static void StelDialog::connectIntProperty	(	QLineEdit *	lineEdit,
		const QString &	propName
	)

staticprotected

Note: This method also works with flag/enum types (TODO. Does it?) You should call something like setInputMask("009") for a 3-place numerical field.

Warning: If the action with propName is invalid/unregistered, or cannot be converted to the required datatype, the application will crash

◆ connectIntProperty() [2/4]

static void StelDialog::connectIntProperty	(	QSpinBox *	spinBox,
		const QString &	propName
	)

staticprotected

Note: This method also works with flag/enum types

Warning: If the action with propName is invalid/unregistered, or cannot be converted to the required datatype, the application will crash

◆ connectIntProperty() [3/4]

static void StelDialog::connectIntProperty	(	QComboBox *	comboBox,
		const QString &	propName
	)

staticprotected

The property is mapped to the selected index of the combobox.

Note: This method also works with flag/enum types

Warning: If the action with propName is invalid/unregistered, or cannot be converted to the required datatype, the application will crash

◆ connectIntProperty() [4/4]

static void StelDialog::connectIntProperty	(	QSlider *	slider,
		const QString &	propName,
		int	minValue,
		int	maxValue
	)

staticprotected

Parameters

slider	The slider which should be connected
propName	The id of the StelProperty which should be connected
minValue	the int value associated with the minimal slider position
maxValue	the int value associated with the maximal slider position

Warning: If the action with propName is invalid/unregistered, or cannot be converted to the required datatype, the application will crash

◆ connectStringProperty()

static void StelDialog::connectStringProperty	(	QComboBox *	comboBox,
		const QString &	propName
	)

staticprotected

The property is mapped to the selected string of the combobox. Make sure the string is available in the Combobox, else the first element may be chosen.

Warning: If the action with propName is invalid/unregistered, or cannot be converted to the required datatype, the application will crash

◆ handleDialogSizeChanged

virtual void StelDialog::handleDialogSizeChanged ( QSizeF size )

virtualslot

When a subclass needs a size-dependent update, implement such update in the subclass version, but call StelDialog::handleDialogSizeChanged() first.

◆ retranslate

virtual void StelDialog::retranslate ( )

pure virtualslot

Needs to be connected to StelApp::languageChanged(). At the very least, if the window is based on a Qt Designer file (.ui), the implementation needs to call the generated class' retranslateUi() method, like this:

if (dialog)

ui->retranslateUi(dialog);
