This widget is similar to the Label widget
(see Section 12, “The Label widget”), but it is intended for
displaying messages over multiple lines. All the text will
be displayed in the same font; if you need to display text
with more than one font, see Section 24, “The Text widget”.
To create a new Message widget as the child
of a root window or frame named parent
w= tk.Message(parent,option, ...)
This constructor returns the new Message
widget. Options may be any of these:
Table 26. Message widget options
aspect
|
Use this option to specify the ratio of width to
height as a percentage. For example, aspect=100 would give you a text message
fit into a square; with aspect=200,
the text area would be twice as wide as high. The
default value is 150, that is, the text will be fit
into a box 50% wider than it is high.
|
bg or background
| The background color behind the text; see Section 5.3, “Colors”. |
bd or borderwidth
|
Width of the border around the widget; see Section 5.1, “Dimensions”. The default is two
pixels. This option is visible only when the relief option is not tk.FLAT.
|
cursor
| Specifies the cursor that appears when the mouse is over the widget; see Section 5.8, “Cursors”. |
font
| Specifies the font used to display the text in the widget; see Section 5.4, “Type fonts”. |
fg or foreground
| Specifies the text color; see Section 5.3, “Colors”. |
highlightbackground
| Color of the focus highlight when the widget does not have focus. See Section 53, “Focus: routing keyboard input”. |
highlightcolor | Color shown in the focus highlight when the widget has the focus. |
highlightthickness | Thickness of the focus highlight. |
justify
|
Use this option to specify how multiple lines of
text are aligned. Use justify=tk.LEFT
to get a straight left margin; justify=tk.CENTER to center each line; and
justify=tk.RIGHT to get a straight
right margin.
|
padx
| Use this option to add extra space inside the widget to the left and right of the text. The value is in pixels. |
pady
| Use this option to add extra space inside the widget above and below the text. The value is in pixels. |
relief
|
This option specifies the appearance of the border
around the outside of the widget; see Section 5.6, “Relief styles”. The default style is tk.FLAT.
|
takefocus
|
Normally, a Message widget will not
acquire focus (see Section 53, “Focus: routing keyboard input”). Use
takefocus=True to add the widget to
the focus traversal list.
|
text
| The value of this option is the text to be displayed inside the widget. |
textvariable
|
If you would like to be able to change the message
under program control, associate this option with a
StringVar instance (see Section 52, “Control variables: the values behind the widgets”). The value of this
variable is the text to be displayed. If you
specify both text and textvariable options, the text option is ignored.
|
width
|
Use this option to specify the width of the text
area in the widget, in pixels. The default width
depends on the displayed text and the value of the
aspect option.
