You can use the configuration to show simple dialogs from the core application. Typically, you
can use the wrapper methods, but for more advanced dialogs you may need to create a message
config explicitly.

@note The values are kept in sync with QMessageBox::StandardButton etc. This means you can
simply cast the values to the other standard buttons without any risk. This goes for other

@property QtMvvm::MessageConfig::type

@default{`MessageConfig::TypeMessageBox`}

The type determines what kind of dialog is show. The type is a general category of dialogs. The
MessageConfig::subType is used to set the final type of dialog shown. It's interpretation
depends on the type used.

It is possible to define your own types, but that means you have to customize the presenters to
add support for those dialogs.

The types supported by default are:

- MessageConfig::TypeMessageBox
- MessageConfig::TypeInputDialog
- MessageConfig::TypeFileDialog

/*!
@property QtMvvm::MessageConfig::subType

@default{<i>Depends on the type used</i>}

The subType is a finer specification of what kind of dialog to show. It depends on the
MessageConfig::type that is used. The possible valid subtypes depend on the MessageConfig::type
used.

It is possible to define your own subtypes, but that means you have to customize the presenters
to add support for those dialogs.

The subtypes supported by default are:

- For MessageConfig::TypeMessageBox:
	- MessageConfig::SubTypeInformation
	- MessageConfig::SubTypeWarning
	- MessageConfig::SubTypeCritical
	- MessageConfig::SubTypeQuestion
	- MessageConfig::SubTypeAbout
- For MessageConfig::TypeInputDialog:
	- The name of the type to get an input value for, e.g. `QString`, `int`, ...
- For MessageConfig::TypeFileDialog:
	- MessageConfig::SubTypeDir
	- MessageConfig::SubTypeOpenFile
	- MessageConfig::SubTypeOpenFiles
	- MessageConfig::SubTypeSaveFile

The title is typically bigger then the rest of the text and serves as a short text to hint the

decorative text.

The text is shown as primary content, a more descriptive label, or tooltip or similar. It can
be of arbitrary length. It's role and contents heavily depend on the type and subtype beeing
used.

The buttons are the buttons in the dialog to "complete" it. Use these flags to select the

the MessageResult::dialogDone signal.

Some dialogs allow the users to enter some kind of result besides of the buttons they can

The view properties are additional properties to be set on the created views. This allows you
to configure the appearance of the dialog from within the core code.

@note The properties are always set on all views. If a view does not have such a property, it
will do nothing. This allows you to set properties for all the different views you support.

message to show:

/*!
@var QtMvvm::MessageConfig::TypeInputDialog

<b>Value:</b> `"input"`

Shows a generic input dialog with a title and a short label, together with some kind of edit
view in order to input a single value. The datatype to get as well as the kind of input view
to create is determined by MessageConfig:subType. Theoretically, and type that can be passed
via QVariant can be used as input value. However, only for the most common types do default
edit views exist. In case you want to use types not present in the list below, you need to
create edit views yourself

 Type				| Widgets edit					| Quick edit
--------------------|-------------------------------|------------
 bool				| QCheckBox						| CheckBox
 switch				| -/-							| Switch
 QString, string	| QLineEdit						| TextField
 int				| QSpinBox						| SpinBox
 double, number		| QDoubleSpinBox				| DoubleSpinBox

 QTime				| QTimeEdit						| -/-
 QDateTime, date	| QDateTimeEdit					| -/-

 QKeySequence		| QKeySequenceEdit				| -/-
 QUrl, url			| QLineEdit with QUrlValidator	| UrlField
 selection, list	| QComboBox						| ListEdit
 radiolist			| -/-							| RadioListEdit

The following types have special properties as well:

- QString, string:
	- `regexp`: A regular expression pattern (QString) to be used as input validator for the
text
	- `patternOptions`: QRegularExpression::PatternOptions as options for the regular
expression
- QUrl, url:
	- `allowedSchemes`: A QStringList with allowed schemes for the URL
- selection, list, radiolist:
	- `listElements`: A list of elemets the user can select from. Can either be:
		- QString elements: They will serve as display value and returned value
		- QVariantMap elements: A map containing the following values:
			- `name`: A QString shown to the user to select
			- `value`: A QVariant value that is returned instead of the selected name
