Pmw.LabeledWidget

Name

Pmw.LabeledWidget() - frame with label

Inherits

Pmw.MegaWidget

Description

This megawidget consists of an interior frame with an associated label which can be positioned on any side of the frame. The programmer can create other widgets within the interior frame.

Options

Options for this megawidget and its base classes are described below.

labelmargin

Initialisation option. If the labelpos option is not None, this specifies the distance between the label component and the rest of the megawidget. The default is 0.

labelpos

Initialisation option. Specifies where to place the label component. If not None, it should be a concatenation of one or two of the letters 'n', 's', 'e' and 'w'. The first letter specifies on which side of the megawidget to place the label. If a second letter is specified, it indicates where on that side to place the label. For example, if labelpos is 'w', the label is placed in the center of the left hand side; if it is 'wn', the label is placed at the top of the left hand side; if it is 'ws', the label is placed at the bottom of the left hand side.

If None, a label component is not created. The default is None.

Components

Components created by this megawidget and its base classes are described below.

hull

This acts as the body for the entire megawidget. Other components are created as children of the hull to further specialise the widget. By default, this component is a Tkinter.Frame.

label

If the labelpos option is not None, this component is created as a text label for the megawidget. See the labelpos option for details. Note that to set, for example, the text option of the label, you need to use the label_text component option. By default, this component is a Tkinter.Label.

labelchildsite

The frame which can contain other widgets to be labelled. By default, this component is a Tkinter.Frame.

Methods

Only methods specific to this megawidget are described below. For a description of its inherited methods, see the manuals for its base classes.

interior()

Return the frame within which the programmer may create widgets. This is the same as component('labelchildsite').

Example

The image at the top of this manual is a snapshot of the window (or part of the window) produced by the following code.

class Demo:
    def __init__(self, parent):

        # Create a frame to put the LabeledWidgets into
        frame = Tkinter.Frame(parent, background = 'grey90')
        frame.pack(fill = 'both', expand = 1)

        # Create and pack the LabeledWidgets.
        column = 0
        row = 0
        for pos in ('n', 'nw', 'wn', 'w'):
            lw = Pmw.LabeledWidget(frame,
                    labelpos = pos,
                    label_text = pos + ' label')
            lw.component('hull').configure(relief='sunken', borderwidth=2)
            lw.grid(column=column, row=row, padx=10, pady=10)
            cw = Tkinter.Button(lw.interior(), text='child\nsite')
            cw.pack(padx=10, pady=10, expand='yes', fill='both')

            # Get ready for next grid position.
            column = column + 1
            if column == 2:
              column = 0
              row = row + 1
