Detailed Description

A Dialog is an interactive set of windows allowing the user to perform some task.

The All Dialogs window is a container window and not visible. All active dialogs will be children of this window, though only one will be active at a time.

Windows

Name	Type	Constructor
All Dialogs	WT_ALL_DIALOGS	alldialogs_new()

Parent

• Root Window

Children

The All Dialogs window has many possible children, e.g.

• Address Book Dialog
• Compose Email Dialog
• GPGME Key Selection Dialog
• ...

Data

The All Dialogs window has no data.

Events

Once constructed, it is controlled by the following events:

Event Type	Handler
NT_WINDOW	alldialogs_window_observer()

The All Dialogs window does not implement MuttWindow::recalc() or MuttWindow::repaint().

Function Documentation

dlg_alias()

static bool dlg_alias ( struct Buffer *  buf, struct AliasMenuData *  mdata  )

static

Here is the caller graph for this function:

dlg_certificate()

int dlg_certificate	(	const char *	title,
		struct CertArray *	carr,
		bool	allow_always,
		bool	allow_skip
	)

Ask the user to validate the certificate -.

Parameters

title	Menu title
carr	Certificate text to display
allow_always	If true, allow the user to always accept the certificate
allow_skip	If true, allow the user to skip the verification

Return values

1	Reject certificate (or menu aborted)
2	Accept certificate once
3	Accept certificate always/skip (see notes)
4	Accept certificate skip

The Verify Certificate Dialog shows a list of signatures for a domain certificate. They can choose whether to accept or reject it.

The possible retvals will depend on the parameters. The options are given in the order: Reject, Once, Always, Skip. The retval represents the chosen option.

int dlg_pager

Display an email, attachment, or help, in a window -.

Parameters

pview

Pager view settings

Return values

0	Success

The Pager Dialog displays an Email to the user.

They can navigate through the Email, search through it and user color commands to highlight it.

From the Pager, the user can also use some Index functions, such as <next-entry> or <delete>.

This pager is actually not so simple as it once was. But it will be again. Currently it operates in 3 modes:

• viewing messages. (PAGER_MODE_EMAIL)
• viewing attachments. (PAGER_MODE_ATTACH)
• viewing other stuff (e.g. help). (PAGER_MODE_OTHER) These can be distinguished by PagerMode in PagerView. Data is not yet polymorphic and is fused into a single struct (PagerData). Different elements of PagerData are expected to be present depending on the mode:
• PAGER_MODE_EMAIL expects data->email and not expects data->body
• PAGER_MODE_ATTACH expects data->email and data->body special sub-case of this mode is viewing attached email message it is recognized by presence of data->fp and data->body->email
• PAGER_MODE_OTHER does not expect data->email or data->body
