Detailed Description

A local copy of StelDialog, the base class for all the GUI windows in Stellarium, included to allow the plug-in to be loaded dynamically on Windows.

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:

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
toolButtonthe QToolButton which shows the color
propertyNamea StelProperty name which must represent a color (coded as Vec3f)
iniNamethe 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
sliderThe slider which should be connected
propNameThe id of the StelProperty which should be connected
minValuethe double value associated with the minimal slider position
maxValuethe 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
sliderThe slider which should be connected
propNameThe id of the StelProperty which should be connected
minValuethe int value associated with the minimal slider position
maxValuethe 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

◆ 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);
