* SECTION:gcr-system-prompt
* @title: GcrSystemPrompt
* @short_description: a system modal prompt
*
* A #GcrPrompt implementation which calls to the system prompter to
* display prompts in a system modal fashion.
*
* Since the system prompter usually only displays one prompt at a time, you
* may have to wait for the prompt to be displayed. Use gcr_system_prompt_open()
* or a related function to open a prompt. Since this can take a long time, you
* should always check that the prompt is still needed after it is opened. A
* previous prompt may have already provided the information needed and you
* may no longer need to prompt.
*
* Use gcr_system_prompt_close() to close the prompt when you're done with it.
*/

* already a prompt being displayed, and the timeout waiting to open the
