WIDGET-SPECIFIC OPTIONS
Name: height |
Class: Height |
Command-Line Switch: -height |
||
Specifies a desired height for the label. If a bitmap |
is being displayed in the label then the value is in |
screen units (i.e. any of the forms acceptable to |
Tk_GetPixels); for text it is in lines of text. If |
this option isn't specified, the label's desired height |
is computed from the size of the bitmap or text being |
displayed in it. |
Name: width |
Class: Width |
Command-Line Switch: -width |
||
Specifies a desired width for the label. If a bitmap |
is being displayed in the label then the value is in |
screen units (i.e. any of the forms acceptable to |
Tk_GetPixels); for text it is in characters. If this |
option isn't specified, the label's desired width is |
computed from the size of the bitmap or text being |
displayed in it.

DESCRIPTION
The label command creates a new window (given by the _p_a_t_h_-
_N_a_m_e argument) and makes it into a label widget. Additional
options, described above, may be specified on the command
line or in the option database to configure aspects of the
label such as its colors, font, text, and initial relief.
The label command returns its _p_a_t_h_N_a_m_e argument. At the
Tk 1
label(n) Tk Commands
time this command is invoked, there must not exist a window
named _p_a_t_h_N_a_m_e, but _p_a_t_h_N_a_m_e's parent must exist.
A label is a widget that displays a textual string or bit- |
map. The label can be manipulated in a few simple ways,
such as changing its relief or text, using the commands
described below.
WIDGET COMMAND
The label command creates a new Tcl command whose name is
_p_a_t_h_N_a_m_e. This command may be used to invoke various opera-
tions on the widget. It has the following general form:
_p_a_t_h_N_a_m_e _o_p_t_i_o_n ?_a_r_g _a_r_g ...?
_O_p_t_i_o_n and the _a_r_gs determine the exact behavior of the com-
mand. The following commands are possible for label widg-
ets:
_p_a_t_h_N_a_m_e configure ?_o_p_t_i_o_n? ?_v_a_l_u_e _o_p_t_i_o_n _v_a_l_u_e ...?
Query or modify the configuration options of the
widget. If no _o_p_t_i_o_n is specified, returns a list
describing all of the available options for _p_a_t_h_N_a_m_e
(see Tk_ConfigureInfo for information on the format of
this list). If _o_p_t_i_o_n is specified with no _v_a_l_u_e, then
the command returns a list describing the one named
option (this list will be identical to the correspond-
ing sublist of the value returned if no _o_p_t_i_o_n is
specified). If one or more _o_p_t_i_o_n-_v_a_l_u_e pairs are
specified, then the command modifies the given widget
option(s) to have the given value(s); in this case the
command returns an empty string. _O_p_t_i_o_n may have any
of the values accepted by the label command.
BINDINGS
When a new label is created, it has no default event bind-
ings: labels are not intended to be interactive.
