# Detail

`MessageDialog` presents a dialog with an image representing the type of message (Error, Question, etc.) alongside some message text. It's simply a convenience widget; you could construct the equivalent of `MessageDialog` from `Dialog` without too much effort, but `MessageDialog` saves typing.

The easiest way to do a modal message dialog is to use `dialogRun`, though you can also pass in the `DialogModal` flag, `dialogRun` automatically makes the dialog modal and waits for the user to respond to it. `dialogRun` returns when any dialog button is clicked.

data ButtonsType

Specify what buttons this dialog should show.

- Prebuilt sets of buttons for the dialog. If none of these choices are appropriate, simply use `ButtonsNone` then call `dialogAddButtons`.

data DialogFlags

Flags used to influence dialog construction.

- Marking a dialog as model will call `widgetSetModal` on the dialog window, the `DialogDestroyWithParent` will call `windowSetDestroyWithParent` on the dialog window. Note that in case the dialog is simply destroyed, no response signal is ever emitted. Finally, `DialogNoSeparator` omits the separator between the action area and the dialog content which is preferable for very simple messages, i.e. those that only contain one button.

# Constructors

messageDialogNew

Arguments

:: Maybe Window | Transient parent of the dialog (or none)
-> [DialogFlags] |
-> MessageType |
-> ButtonsType |
-> String | The text of the message
-> IO MessageDialog |

Create a new message dialog, which is a simple dialog with an icon indicating the dialog type (error, warning, etc.) and some text the user may want to see. When the user clicks a button a "response" signal is emitted with response IDs from `ResponseType`. See `Dialog` for more details.

messageDialogNewWithMarkup

Arguments

:: Maybe Window | Transient parent of the dialog (or none)
-> [DialogFlags] |
-> MessageType |
-> ButtonsType |
-> Markup | The text of the message
-> IO MessageDialog |

Creates a new message dialog, which is a simple dialog with an icon indicating the dialog type (error, warning, etc.) and some text which is marked up with the Pango text markup language. When the user clicks a button a "response" signal is emitted with response IDs from `ResponseType`. See `Dialog` and `PangoMarkup` for more details.

- Available since Gtk+ version 2.4

# Methods

messageDialogSetMarkup

Arguments

:: MessageDialogClass self |
=> self |
-> Markup | `str` - markup string (see Pango markup format)
-> IO () |

Sets the text of the message dialog to be `str`, which is marked up with the Pango text markup language.

- Available since Gtk+ version 2.4

messageDialogSetImage

Arguments

:: (MessageDialogClass self, WidgetClass image) |
=> self |
-> image | `image` - the image
-> IO () |

Sets the dialog's image to `image`.

- Available since Gtk+ version 2.10

messageDialogSetSecondaryMarkup

Arguments

:: MessageDialogClass self |
=> self |
-> String | `str` - markup string (see Pango markup format)
-> IO () |

messageDialogSetSecondaryText

Arguments

:: MessageDialogClass self |
=> self |
-> String | `str` - text to be shown as second line
-> IO () |
