- 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

- 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.
