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 scrolled text. The default is <strong>10</strong>.</p> </dd></dl> <a name=option.bordery></a> <dl><dt> <strong>bordery </strong></dt><dd> Initialisation option. The padding above and below the scrolled text. The default is <strong>10</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.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.scrolledtext></a> <dl><dt> <strong>scrolledtext </strong></dt><dd> The scrolled text to contain the text for the dialog. By default, this component is a <a href="ScrolledText.html">Pmw.ScrolledText</a>.</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> <dt> <h3>Component aliases</h3></dt><dd> Sub-components of components of this megawidget may be accessed via the following aliases.<p></p> <dl><dt> <strong>label </strong></dt><dd> Alias for <strong>scrolledtext_label</strong>. </dd></dl> <dl><dt> <strong>text </strong></dt><dd> Alias for <strong>scrolledtext_text</strong>. </dd></dl> </dd> <a name=methods></a> <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="ScrolledText.html#methods">Pmw.ScrolledText</a></strong> class are forwarded by this megawidget to the <strong>scrolledtext</strong> component. <p></p> <a name=method.bbox></a> <dl><dt> <strong>bbox</strong>(<em>index</em>)</dt><dd> This method is explicitly forwarded to the <strong>text</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> </dd></dl> </dd> <dt> <h3>Example</h3></dt><dd> The image at the top of this manual is a snapshot of the window (or part of the window) produced by the following code.<p></p> <pre> class Demo: def __init__(self, parent): # Create the dialog. dialog = Pmw.TextDialog(parent, scrolledtext_labelpos = 'n', title = 'My TextDialog', defaultbutton = 0, label_text = 'Lawyer jokes') dialog.withdraw() dialog.insert('end', jokes) dialog.configure(text_state = 'disabled') # Create button to launch the dialog. w = Tkinter.Button(parent, text = 'Show text dialog', command = dialog.activate) w.pack(padx = 8, pady = 8) jokes = """ Q: What do you call 5000 dead lawyers at the bottom of the ocean?
