______________________________________________________________________________
Tk_Init, Tk_SafeInit − add Tk to an interpreter and make a new Tk application.
#include <tk.h>

Tk_Init(interp)
int
Tk_SafeInit(interp)
|
Tcl_Interp *interp (in) |
Interpreter in which to load Tk. Tk should not already be loaded in this interpreter. |
_________________________________________________________________
Tk_Init is the package initialization procedure for Tk. It is normally invoked by the Tcl_AppInit procedure for an application or by the load command. Tk_Init adds all of Tk’s commands to interp and creates a new Tk application, including its main window. If the initialization is successful Tk_Init returns TCL_OK; if there is an error it returns TCL_ERROR. Tk_Init also leaves a result or error message in interp->result.
If there is a variable argv in interp, Tk_Init treats the contents of this variable as a list of options for the new Tk application. The options may have any of the forms documented for the wish application (in fact, wish uses Tk_Init to process its command-line arguments).
Tk_SafeInit is identical to Tk_Init except that it removes all Tk commands that are considered unsafe. Those commands and the reasons for their exclusion are:
|
bell |
Continuous ringing of the bell is a nuisance. |
clipboard
A malicious script could replace the contents of the clipboard with the string "rm -r *" and lead to surprises when the contents of the clipboard are pasted.
|
grab |
Grab can be used to block the user from using any other applications. | ||
|
menu |
Menus can be used to cover the entire screen and to steal input from the user. |
selection
See clipboard.
|
send |
Send can be used to cause unsafe interpreters to execute commands. | ||
|
tk |
The tk command recreates the send command, which is unsafe. | ||
|
tkwait |
Tkwait can block the containing process forever |
toplevel
Toplevels can be used to cover the entire screen and to steal input from the user.
|
wm |
If toplevels are ever allowed, wm can be used to remove decorations, move windows around, etc. |
