<p>Pmw.ComboBoxDialog() -
selection dialog displaying a list and an entry field
<dt> <h3>Inherits
</h3></dt><dd>
<a href=
"Dialog.html">Pmw.Dialog
</a><br>
<dt> <h3>Description
</h3></dt><dd>
A combobox dialog is a dialog window which displays a list and
an entry field which can be used to prompt the user for a value.
</p>
<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
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>
<a name=option.borderx
></a>
Initialisation option. The padding to the left and right of the combobox. The default is
<strong>10</strong>.
</p>
<a name=option.bordery
></a>
Initialisation option. The padding above and below the combobox. The default is
<strong>10</strong>.
</p>
<a name=option.buttonboxpos
></a>
<dl><dt> <strong>buttonboxpos
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>
<a name=option.buttons
></a>
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>
<a name=option.command
></a>
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>
<a name=option.deactivatecommand
></a>
<dl><dt> <strong>deactivatecommand
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>
<a name=option.defaultbutton
></a>
<dl><dt> <strong>defaultbutton
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>
<a name=option.master
></a>
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>
<a name=option.separatorwidth
></a>
<dl><dt> <strong>separatorwidth
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>
<a name=option.title
></a>
This is the title that the window manager displays in the title
bar of the window. The default is
<strong>None
</strong>.
</p>
<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
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>
<a name=component.combobox
></a>
<dl><dt> <strong>combobox
The combobox for the user to enter a value. By default it is
created using the option
<code>dropdown =
0</code>. By default, this component is a
<a href=
"ComboBox.html">Pmw.ComboBox
</a>.
</p>
<a name=component.dialogchildsite
></a>
<dl><dt> <strong>dialogchildsite
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>
<a name=component.hull
></a>
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>
<a name=component.separator
></a>
<dl><dt> <strong>separator
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>
<dt> <h3>Component aliases
</h3></dt><dd>
Sub-components of components of this megawidget
may be accessed via the following aliases.
<p></p>
Alias for
<strong>combobox_entry
</strong>.
Alias for
<strong>combobox_label

Alias for
<strong>combobox_listbox

<dt> <h3>Methods
</h3></dt><dd>
Only methods specific to this megawidget are described below.
For a description of its inherited methods, see the
manual for its base class
<strong><a href=
"Dialog.html#methods">Pmw.Dialog
</a></strong>.
In addition, methods from the
<strong><a href=
"ComboBox.html#methods">Pmw.ComboBox
</a></strong> class
are forwarded by this megawidget to the
<strong>combobox
</strong> component.
<dl><dt> <strong>bbox
</strong>(
<em>index
</em>)
</dt><dd>
This method is explicitly forwarded to the
<strong>combobox
</strong> component's
<code>bbox()
</code> method. Without this explicit forwarding, the
<code>bbox()
</code>
method (aliased to
<code>grid_bbox()
</code>) of the
<strong>hull
</strong> would be invoked,
which is probably not what the programmer intended.
</p>
<dl><dt> <strong>size
</strong>()
</dt><dd>
This method is explicitly forwarded to the
<strong>combobox
</strong> component's
<code>size()
</code> method. Without this explicit forwarding, the
<code>size()
</code>
method (aliased to
<code>grid_size()
</code>) of the
<strong>hull
</strong> would be invoked,
which is probably not what the programmer intended.
