## Object Hierarchy

        GInterface
        ╰── GcrPrompt

## Prerequisites

GcrPrompt requires GObject.

## Known Implementations

GcrPrompt is implemented by GcrPromptDialog and GcrSystemPrompt.

## Description

A GcrPrompt represents a prompt displayed to the user. It is an interface with various implementations.

Various properties are set on the prompt, and then the prompt is displayed the various prompt methods like `gcr_prompt_password_run()`.

A GcrPrompt may be used to display multiple related prompts. Most implemantions do not hide the window between display of multiple related prompts, and the GcrPrompt must be closed or destroyed in order to make it go away. This allows the user to see that the prompts are related.

Use GcrPromptDialog to create an in-process GTK+ dialog prompt. Use GcrSystemPrompt to create a system prompt in a prompter process.

The prompt implementation will always display the GcrPrompt:message property, but may choose not to display the GcrPrompt:description or GcrPrompt:title properties.

## Functions

### gcr_prompt_password ()

Prompts for password. Set the various properties on the prompt before calling this method to explain which password should be entered.

This method will block until the a response is returned from the prompter.

A password will be returned if the user enters a password successfully. The returned password is valid until the next time a method is called to display another prompt.

`NULL` will be returned if the user cancels or if an error occurs. Check the `error` argument to tell the difference.
