</p>
</dd>
<dt> <h3>Inherits</h3></dt><dd>
<a href="Dialog.html">Pmw.Dialog</a><br>
</dd>
<dt> <h3>Description</h3></dt><dd>
<p>
A message dialog is a dialog window which displays a simple
message to the user along with one or more buttons to press.</p>
<p></p>
</dd>
<dt> <h3>Options</h3></dt><dd>
Options for this megawidget and its base
classes are described below.<p></p>
<a name=option.activatecommand></a>
<dl><dt> <strong>activatecommand
</strong></dt><dd>
If this is callable, it will be called whenever the megawidget is
activated by a call to <code>activate()</code>. The default is <strong>None</strong>.</p>
</dd></dl>
<a name=option.borderx></a>
<dl><dt> <strong>borderx
</strong></dt><dd>
Initialisation option. The padding to the left and right of the text message and icon. The default is <strong>20</strong>.</p>
</dd></dl>
<a name=option.bordery></a>
<dl><dt> <strong>bordery
</strong></dt><dd>
Initialisation option. The padding above and below the text message and icon. The default is <strong>20</strong>.</p>
</dd></dl>
<a name=option.buttonboxpos></a>
<dl><dt> <strong>buttonboxpos
</strong></dt><dd>
Initialisation option. Specifies on which side of the dialog window to place the button
box. Must be one of <strong>'n'</strong>, <strong>'s'</strong>, <strong>'e'</strong> or <strong>'w'</strong>. The default is <strong>'s'</strong>.</p>
</dd></dl>
<a name=option.buttons></a>
<dl><dt> <strong>buttons
</strong></dt><dd>
This must be a tuple or a list and specifies the names on the
buttons in the button box. The default is <strong>('OK',)</strong>.</p>
</dd></dl>
<a name=option.command></a>
<dl><dt> <strong>command
</strong></dt><dd>
Specifies a function to call whenever a button in the button box
is invoked or the window is deleted by the window manager. The
function is called with a single argument, which is the name of
the button which was invoked, or <strong>None</strong> if the window was deleted
by the window manager.</p>
<p> If the value of <strong>command</strong> is not callable, the default behaviour
is to deactivate the window if it is active, or withdraw the
window if it is not active. If it is deactivated, <code>deactivate()</code>
is called with the button name or <strong>None</strong> as described above. The default is <strong>None</strong>.</p>
</dd></dl>
<a name=option.deactivatecommand></a>
<dl><dt> <strong>deactivatecommand
</strong></dt><dd>
If this is callable, it will be called whenever the megawidget is
deactivated by a call to <code>deactivate()</code>. The default is <strong>None</strong>.</p>
</dd></dl>
<a name=option.defaultbutton></a>
<dl><dt> <strong>defaultbutton
</strong></dt><dd>
Specifies the default button in the button box. If the <strong><Return></strong>
key is hit when the dialog has focus, the default button will be
invoked. If <strong>defaultbutton</strong> is <strong>None</strong>, there will be no default
button and hitting the <strong><Return></strong> key will have no effect. The default is <strong>None</strong>.</p>
</dd></dl>
<a name=option.iconmargin></a>
<dl><dt> <strong>iconmargin
</strong></dt><dd>
Initialisation option. The padding between the text message and icon. The default is <strong>20</strong>.</p>
</dd></dl>
<a name=option.iconpos></a>
<dl><dt> <strong>iconpos
</strong></dt><dd>
Initialisation option. Specifies on which side of the text message to place the icon.
Must be one of <strong>'n'</strong>, <strong>'s'</strong>, <strong>'e'</strong> or <strong>'w'</strong>. The default is <strong>None</strong>.</p>
</dd></dl>
<a name=option.master></a>
<dl><dt> <strong>master
</strong></dt><dd>
This is used by the <code>activate()</code> method to control whether the
window is made <em>transient</em> during modal dialogs. See the
<code>activate()</code> method. The default is <strong>'parent'</strong>.</p>
</dd></dl>
<a name=option.separatorwidth></a>
<dl><dt> <strong>separatorwidth
</strong></dt><dd>
Initialisation option. If this is greater than <strong>0</strong>, a separator line with the specified
width will be created between the button box and the child site,
as a component named <strong>separator</strong>. Since the default border of the
button box and child site is <strong>raised</strong>, this option does not
usually need to be set for there to be a visual separation between
the button box and child site. The default is <strong>0</strong>.</p>
</dd></dl>
<a name=option.title></a>
<dl><dt> <strong>title
</strong></dt><dd>
This is the title that the window manager displays in the title
bar of the window. The default is <strong>None</strong>.</p>
</dd></dl>
</dd>
<dt> <h3>Components</h3></dt><dd>
Components created by this megawidget and its base
classes are described below.<p></p>
<a name=component.buttonbox></a>
<dl><dt> <strong>buttonbox
</strong></dt><dd>
This is the button box containing the buttons for the dialog. By
default it is created with the options
<code>(hull_borderwidth = 1, hull_relief = 'raised')</code>. By default, this component is a <a href="ButtonBox.html">Pmw.ButtonBox</a>.</p>
</dd></dl>
<a name=component.dialogchildsite></a>
<dl><dt> <strong>dialogchildsite
</strong></dt><dd>
This is the child site for the dialog, which may be used to
specialise the megawidget by creating other widgets within it. By
default it is created with the options
<code>(borderwidth = 1, relief = 'raised')</code>. By default, this component is a Tkinter.Frame.</p>
</dd></dl>
<a name=component.hull></a>
<dl><dt> <strong>hull
</strong></dt><dd>
This acts as the body for the entire megawidget. Other components
are created as children of the hull to further specialise this
class. By default, this component is a Tkinter.Toplevel.</p>
</dd></dl>
<a name=component.icon></a>
<dl><dt> <strong>icon
</strong></dt><dd>
If the <strong>iconpos</strong> option is not <strong>None</strong>, this component is created
to contain the icon label for the dialog. To display a bitmap as
an icon, set the <strong>icon_bitmap</strong> component option to any of the
forms acceptable to Tk, such as <strong>'warning'</strong> or <strong>'error'</strong>. By default, this component is a Tkinter.Label.</p>
</dd></dl>
<a name=component.message></a>
<dl><dt> <strong>message
</strong></dt><dd>
The label to contain the text message for the dialog. To set
the text, use the <strong>message_text</strong> component option. By default, this component is a Tkinter.Label.</p>
</dd></dl>
<a name=component.separator></a>
<dl><dt> <strong>separator
</strong></dt><dd>
If the <strong>separatorwidth</strong> initialisation option is non-zero, the
<strong>separator</strong> component is the line dividing the area between the
button box and the child site. By default, this component is a Tkinter.Frame.</p>
</dd></dl>
</dd>
<a name=methods></a>
