Graphics.UI.Gtk.Windows.MessageDialog

A convenient message window

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 dialogAddButton.

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.

messageDialogNew

Arguments

:: GlibString string

=> 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

:: GlibString string

=> Maybe Window

Transient parent of the dialog (or none)

-> [DialogFlags]

-> MessageType

-> ButtonsType

-> string

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.
