- xtAppInitialize
-
- DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN
- This is the command that creates the root widget ``.''
-
-
- OOOOPPPPTTTTIIIIOOOONNNNSSSS
- The function xtAppInitialize has these options
- -class _c_l_a_s_s
- -fallbackResources _r_e_s_o_u_r_c_e_s
- These are in a tcl list, as in
- {
- {*list.visibleItemCount: 10}
- {*quit.labelString: Quit}
- }
- -options _o_p_t_i_o_n_s
- These set the application options. The _o_p_t_i_o_n_s is a list of
- option values. Each option value consists of the command line
- option (such as -helpFile), the resource name (such as
- helpFile) and the type of command line argument supported.
- Possible values for this are
- noArg
- sepArg
- stickyArg
- resArg
- skipArg
- skipLine
- For example,
- -options {
- {-helpFile helpFile sepArg}
- {-showHelp showHelp isArg}
- }

- according to the mode specified. This can be `r' for read, `w' for
- write or `x' for exception. Whenever the file is ready for the
- requested operation the tcl function is called to handle it. The
- command returns an XID which is an identifier for the input handler.
-
- rrrreeeemmmmoooovvvveeeeIIIInnnnppppuuuutttt _i_n_p_u_t_I_D
- This method removes the file handler added by addInput. It takes as
- argument the identifier returned from ``addInput''.
-
- aaaaddddddddTTTTiiiimmmmeeeerrrr _i_n_t_e_r_v_a_l _c_o_m_m_a_n_d
- This method adds the tcl command to an Xt timer. The interval is in
- milliseconds. The command returns an XID which is an identifier for
- the input handler.
-
- rrrreeeemmmmoooovvvveeeeTTTTiiiimmmmeeeerrrr _t_i_m_e_r_I_D
- This method removes the timer added by addTimer. It takes as
- argument the identifier returned from ``addTimer''. Note that if an
- attempt is made to remove a timer that has gone off, Xt has
- unspecified behaviour.

- ggggeeeettttAAAAppppppppRRRReeeessssoooouuuurrrrcccceeeessss _r_e_s_o_u_r_c_e_s
- This extracts the application resources as set in the resource
- database. The _r_e_s_o_u_r_c_e_s argument is a list of resource sets. Each
- one consists of the resource name, its class, the default value and
- the name of a tcl variable to store the value in. For example,
- {
- {helpFile HelpFile "" tcl_helpFile }
- {showHelp ShowHelp 0 tcl_show}
- }
-
- mmmmaaaaiiiinnnnLLLLoooooooopppp
- This starts the Xt event processing loop
-
- pppprrrroooocccceeeessssssssEEEEvvvveeeennnntttt
- This processes the next event, along with any timers and input
- handlers. It is supplied here for use in modal dialogs.
