Tk_SetAppName — Set the name of an application for 'send' commands
#include <tk.h>
const char *
Tk_SetAppName(tkwin, name)
- Tk_Window tkwin
(in)
- Token for window in application. Used only to select a
particular application.
- const char *name (in)
- Name under which to register the application.
Tk_SetAppName associates a name with a given application and
records that association on the display containing with the
application's main window. After this procedure has been invoked,
other applications on the display will be able to use the
send command to invoke
operations in the application. If name is already in use by
some other application on the display, then a new name will be
generated by appending “ #2” to name; if this name is
also in use, the number will be incremented until an unused name is
found. The return value from the procedure is a pointer to the name
actually used.
If the application already has a name when Tk_SetAppName
is called, then the new name replaces the old name.
Tk_SetAppName also adds a send command to the application's
interpreter, which can be used to send commands from this
application to others on any of the displays where the application
has windows.
The application's name registration persists until the
interpreter is deleted or the send command is deleted from
interp, at which point the name is automatically
unregistered and the application becomes inaccessible via
send. The application can
be made accessible again by calling Tk_SetAppName.
Tk_SetAppName is called automatically by Tk_Init, so applications do not
normally need to call it explicitly.
The command tk appname
provides Tcl-level access to the functionality of
Tk_SetAppName.
