How do I find out values for QML enumerations in docs?

Asperamanca

Example case:
I use the TextEdit QML type, and want to set horizontalAlignment and verticalAlignment from C++ via property binding.

Docs state:

Valid values for horizontalAlignment are:

TextEdit.AlignLeft (default)
TextEdit.AlignRight
TextEdit.AlignHCenter
TextEdit.AlignJustify

Valid values for verticalAlignment are:

TextEdit.AlignTop (default)
TextEdit.AlignBottom
TextEdit.AlignVCenter

The values are not linked, nor is a C++-side Enumeration mentioned. How do I find out which values to use? What type should the Q_PROPERTY have?

They should refer to the Qt AlignmentFlag enum.
Therefore, you should be able to do something like this:

Q_PROPERTY(int hAlign READ getHorizontalAlignment NOTIFY objectChanged)
Q_PROPERTY(int vAlign READ getVerticalAlignment NOTIFY objectChanged)

int MyClass::getHorizontalAlignment()
{
    return Qt::AlignHCenter;
}
int MyClass::getVerticalAlignment()
{
    return Qt::AlignBottom;
}

TextEdit {
    anchors.fill: parent
    text: "Hello World"
    horizontalAlignment: MyContextPropertyOrModel.hAlign
    verticalAlignment: MyContextPropertyOrModel.vAlign
}
