GParamSpec {RGtk2} | R Documentation

## Parameter metadata in GObject

### Description

`GParamSpec` is an object structure that encapsulates the metadata required to specify parameters, such as e.g. `GObject` properties.

### Usage

    gParamSpec(type, name, nick = NULL, blurb = NULL, flags = NULL, ...)
    as.GParamSpec(x)

### Arguments

`type` | a string naming the R type (ie 'character', 'numeric', ...) corresponding to the desired `GParamSpec` (property) type
`name` | the name of the `GParamSpec` (property)
`nick` | the nickname of the `GParamSpec` (property)
`blurb` | a short string description of the `GParamSpec` (property)
`flags` | a vector of values from the `GParamFlags` enumeration - please see the GObject documentation for more information
`...` | named arguments specific to the type of `GParamSpec` - please see the GObject documentation for more information
`x` | A list corresponding to a `GParamSpec` - the class of the list should be the name of the `GParamSpec` type

### Details

As a transparent type, the various `GParamSpec` structures should be returned to R as corresponding lists, and `as.GParamSpec` coerces a list to one understandable by the C wrappers, assuming that the class of the list is the name of the `GParamSpec` type. `gParamSpec` is a more user-friendly wrapper to `as.GParamSpec` that constructs the correctly-classed list on the fly from its arguments.

### Value

A list representing a `GParamSpec`, ready to be passed to the underlying C libraries
