ValueCommandInput Object

Derived from: CommandInput Object


Provides a command input to get a unit based value from the user.

Defined in namespace "adsk::core" and the header file is <Core/UserInterface/ValueCommandInput.h>.


Name Description
classType Static function that all classes support that returns the type of the class as a string. The returned string matches the string returned by the objectType property. For example if you have a reference to an object and you want to check if it's a SketchLine you can use myObject.objectType == fusion.SketchLine.classType().
deleteMe Deletes this Command input.


Name Description
commandInputs Gets the CommandInputs class of the parent, which can be a Command, GroupCommandInput or TabCommandInput.
expression Gets or sets the expression displayed in the input field. This can contain equations and references to parameters. It is evaluated using the specified unit type.
id Gets the unique identifier for this input in the command's CommandInputs.
isEnabled Gets or sets if this input is currently enabled or disabled for user interaction.
isFullWidth Gets or sets if this input fills the entire width of the dialog. If true, the name is ignored and the input control will fill the entire width of the command dialog. The default value for this property in a new command input if false, or not to fill the width. This property does not apply to GroupCommandInputs or TabCommandInputs.
isValid Indicates if this object is still valid, i.e. hasn't been deleted or some other action done to invalidate the reference.
isValidExpression Returns true if the current expression is valid and can be evaluated. If this is false, the value returned should be ignored because there currently is not a valid value.
isVisible Gets or sets if this input will be visible to the user.
name Gets the user visible name of this input.
objectType This property is supported by all objects in the API and returns a string that contains the full name (namespace::objecttype) describing the type of the object.

It's often useful to use this in combination with the classType method to see if an object is a certain type. For example: if obj.objectType == adsk.core.Point3D.classType():
parentCommand Gets the parent Command.
parentCommandInput Gets the parent CommandInput if this commandInput is the child of a TabCommandInput or GroupCommandInput. Returns null if there is no parent.
toolClipFilename Gets or sets the full filename of the image file (PNG) used for the tool clip. The tooltip is always shown but as the user hovers over the control it will progressively display the tool clip and description text.
tooltip Gets or sets the base tooltip string. This is always shown for commands. If the tooltip description and/or tool clip are also specified then the tooltip will progressively display more information as the user hovers the mouse over the control.
tooltipDescription Gets or sets additional text to display progressively along with the tooltip. The text for the description can contain some basic HTML formatting tags to format the tags. For example the br tag can be used to create multiple paragraphs. The tooltip is always shown but as the user hovers over the control it will progressively display the tool clip and description text.
unitType Gets and sets the unit type that is used when evaluating the user's input.
value Gets or sets the value associated with this input. The value is always in the database units of the unit type specified. For example, if the unit type is "inch" this value is in centimeters since centimeters are the database length unit. When setting the value it is converted into a string using the unit type and displayed in the input box. When getting the value, the current expression string is evaluated and the database value for the unit type is returned.

The isValidExpression property should be checked before using this value within the command because if the expression can't be evaluated there isn't a valid value. Fusion 360 won't allow the execution of a command that contains ValueCommandInput object with invalid expressions so you can dependably use the value in the execute event of the command.

Name Description
Command Inputs API Sample

Creates a command dialog that demonstrates all of the available command inputs.

To use the sample, create a new Python or C++ script and copy and paste this code, replacing the default code. You also need to unpack this zip file which contains a resource folder into the same folder where the source code file (.py or .cpp) is.
