Detailed Description

Base class of all Fields in MLAB.

The MLABField is used standalone by macro modules and to wrap Inventor or ML Fields A field normally has a MLABFieldOwner which is a MLABModule in the current implementation. To get a field of a module, use the field() method of MLABModule. There are common stringValue() and setStringValue() methods in this base class and specialized set/get methods in the derived class:

The name of the field is given in the "name" property:

ctx.field("somefield").name

or alternatively

ctx.field("somefield").getName()

The fields data type can be read by using the "type" property.

ctx.field("somefield").type

or alternatively

ctx.field("somefield").getType()

The data type is generated from the fields C++ class name by stripping of the prefix 'MLAB' and the trailing 'Field', e.g. getType() of an MLABBoolField returns Bool.

Note
To ensure that this mechanism works for all classes derived from MLABField it is important that the Q_OBJECT macro is added to the class definition.

All fields that have a value implement a "value" property, which can be accessed via Scripting for read/write access:

Read access:

ctx.field("somefield").value

Write access:

ctx.field("someIntField").value = 42
ctx.field("someStringField").value = "Test"

The "value" property is always of the typical type of the field, thus a string field returns a string, while an int field returns an integer. Type conversion is done automatically by QT.

Field data types include:

Member Function Documentation

◆ comment

QString MLABField::comment ( )
slot

Returns the comment string.

◆ connectedField

MLABField* MLABField::connectedField ( )
slot

Returns the input connection of this field (connected field, NULL if none), alias for inputField().

In this case, this field is the destination of a connection.

◆ connectFrom

bool MLABField::connectFrom ( MLABField *  field)
slot

Connects to given field (if already connected, automatically disconnects old connection) and returns whether this operation was successful.

◆ connectFromUndoable

bool MLABField::connectFromUndoable ( MLABField *  field)
slot

Connects/disconnects undoable.

◆ disconnect

void MLABField::disconnect ( )
slot

Disconnects input.

◆ disconnectAll

void MLABField::disconnectAll ( )
slot

Disconnects the input and all output fields.

◆ disconnectOutputs

void MLABField::disconnectOutputs ( )
slot

Disconnects all outputs.

◆ fullName

QString MLABField::fullName ( ) const
slot

Returns the full name for debugging. This is the name of the owner (if existing) with the name of the field.

◆ getName

QString MLABField::getName ( ) const
inlineslot

Returns the name of the field. You can also use the name property.

◆ getType

QString MLABField::getType ( ) const
inlineslot

Returns the data type of the field by stripping of the prefix 'MLAB' and the trailing 'Field' of the fields C++ class name, e.g. getType() of an MLABBoolField returns Bool. See Detailed Description above for the available field types.

◆ infoString

QString MLABField::infoString ( )
slot

Returns an info string (for printing).

◆ inputField

MLABField* MLABField::inputField ( )
slot

Returns the input connection of this field (connected field, NULL if none), alias for connectedField().

In this case, this field is the destination of a connection.

◆ isConnected

bool MLABField::isConnected ( )
slot

Returns whether the field has an input connection.

◆ isConnectedToFieldInSameNetwork

bool MLABField::isConnectedToFieldInSameNetwork ( )
slot

Returns whether the field is connected to another field in the same network.

Returns true if connected to at least one field in the same network.

◆ isConnectionInSameNetworkPossible

bool MLABField::isConnectionInSameNetworkPossible ( MLABField *  field)
slot

Returns whether a connection between the fields is possible using isConnectionPossible() and if the fields are in the same network.

◆ isConnectionPossible

virtual bool MLABField::isConnectionPossible ( MLABField *  field)
virtualslot

Returns whether a connection between the fields is possible (taking into account the input/output type and not regarding the networks the fields are in).

NOTE: even if this method tries to be accurate, it may return true and connectFrom is still not possible. This is due to the fact that not all Inventor fields can be connected with each other and this can only be detected when trying to connect the fields.

◆ isEditable

bool MLABField::isEditable ( ) const
inlineslot

Returns whether the field is editable in the GUI (can be overridden in self-defined panels).

◆ isFilePath

bool MLABField::isFilePath ( )

Returns whether this field is a file path (only applicable for string fields)

◆ isHidden

bool MLABField::isHidden ( )
slot

Returns whether the field is hidden.

◆ isIgnored

bool MLABField::isIgnored ( )
slot

Returns whether this field is ignored. This is only used with Inventor fields.

◆ isInOut

bool MLABField::isInOut ( )
inlineslot

Returns whether this field is marked as an input/output (parameter) field.

◆ isInput

bool MLABField::isInput ( )
inlineslot

Returns whether this field is marked as an input field.

Mark field as input only, as output only or as InOut: a newly created field is InOut. mainly these flags are used to avoid wrong drag/drop connections!

◆ isInSameNetwork

bool MLABField::isInSameNetwork ( MLABField *  field)
slot

Returns whether the field is in the same network as the given field.

bool MLABField::isInterfaceField ( )

Returns whether this field is marked as an output field.

◆ isParameterField

bool MLABField::isParameterField ( )
inlineslot

Returns whether this is a parameter field.

◆ isPersistent

bool MLABField::isPersistent ( ) const
inlineslot

Returns whether the field is persistent, i.e. if its values is saved together with the module.
