/* Generate tk script based upon config.in * * Version 1.0 * Eric Youngdale * 10/95 * * 1996 01 04 * Avery Pennarun - Aesthetic improvements. * * 1996 01 24 * Avery Pennarun - Bugfixes and more aesthetics. * * 1996 03 08 * Avery Pennarun - The int and hex config.in commands work right. * - Choice buttons are more user-friendly. * - Disabling a text entry line greys it out properly. * - dep_tristate now works like in Configure. (not pretty) * - No warnings in gcc -Wall. (Fixed some "interesting" bugs.) * - Faster/prettier "Help" lookups. * * 1996 03 15 * Avery Pennarun - Added new sed script from Axel Boldt to make help even * faster. (Actually awk is downright slow on some machines.) * - Fixed a bug I introduced into Choice dependencies. Thanks * to Robert Krawitz for pointing this out. * * 1996 03 16 * Avery Pennarun - basic "do_make" support added to let sound config work. * * 1996 03 25 * Axel Boldt - Help now works on "choice" buttons. * * 1996 04 06 * Avery Pennarun - Improved sound config stuff. (I think it actually works * now!) * - Window-resize-limits don't use ugly /usr/lib/tk4.0 hack. * - int/hex work with tk3 again. (The "cget" error.) * - Next/Prev buttons switch between menus. I can't take * much credit for this; the code was already there, but * ifdef'd out for some reason. It flickers a lot, but * I suspect there's no "easy" fix for that. * - Labels no longer highlight as you move the mouse over * them (although you can still press them... oh well.) * - Got rid of the last of the literal color settings, to * help out people with mono X-Windows systems. * (Apparently there still are some out there!) * - Tabstops seem sensible now. * * 1996 04 14 * Avery Pennarun - Reduced flicker when creating windows, even with "update * idletasks" hack. * * TO DO: * - clean up - there are useless ifdef's everywhere. * - better comments throughout - C code generating tcl is really cryptic. * - eliminate silly "update idletasks" hack to improve display speed and * reduce flicker. But how? * - make canvas contents resize with the window (good luck). * - some way to make submenus inside of submenus (ie. Main->Networking->IP) * (perhaps a button where the description would be) * - make the main menu use the same tcl code as the submenus. * - make choice and int/hex input types line up vertically with * bool/tristate. * - general speedups - how? The canvas seems to slow it down a lot. * - choice buttons should default to the first menu option, rather than a * blank. Also look up the right variable when the help button * is pressed. * - clean up +/- 16 confusion for enabling/disabling variables; causes * (theoretical, at the moment) problems with dependencies. * */ #include <stdio.h> #include <unistd.h> #include "tkparse.h" #ifndef TRUE #define TRUE (1) #endif #ifndef FALSE #define FALSE (0) #endif /* * This is the total number of submenus that we have. */ static int tot_menu_num =0; /* * Generate portion of wish script for the beginning of a submenu. * The guts get filled in with the various options. */ static void start_proc(char * label, int menu_num, int flag) { if( flag ) printf("menu_option menu%d %d \"%s\"\n", menu_num, menu_num, label); printf("proc menu%d {w title} {\n", menu_num); printf("\tcatch {destroy $w}\n"); printf("\ttoplevel $w -class Dialog\n"); printf("\twm withdraw $w\n"); printf("\tmessage $w.m -width 400 -aspect 300 -text \\\n"); printf("\t\t\"%s\" -relief raised\n",label); printf("\tpack $w.m -pady 10 -side top -padx 10\n"); printf("\twm title $w \"%s\" \n\n", label); /* * Attach the "Prev", "Next" and "OK" buttons at the end of the window. */ printf("\tset oldFocus [focus]\n"); printf("\tframe $w.f\n"); printf("\tbutton $w.f.back -text \"Main Menu\" \\\n" "\t\t-width 15 -command \"destroy $w; focus $oldFocus; update_mainmenu $w\"\n"); printf("\tbutton $w.f.next -text \"Next\" \\\n" "\t\t-width 15 -command \" destroy $w; focus $oldFocus; menu%d .menu%d \\\"$title\\\"\"\n", menu_num+1, menu_num+1); if (menu_num == tot_menu_num) printf("\t$w.f.next configure -state disabled\n"); printf("\tbutton $w.f.prev -text \"Prev\" \\\n" "\t\t-width 15 -command \" destroy $w; focus $oldFocus; menu%d .menu%d \\\"$title\\\"\"\n", menu_num-1, menu_num-1); if (1 == menu_num) printf("\t$w.f.prev configure -state disabled\n"); printf("\tpack $w.f.back $w.f.next $w.f.prev -side left -expand on\n"); printf("\tpack $w.f -pady 10 -side bottom -anchor w -fill x\n"); /* * Lines between canvas and other areas of the window. */ printf("\tframe $w.topline -relief ridge -borderwidth 2 -height 2\n"); printf("\tpack $w.topline -side top -fill x\n\n"); printf("\tframe $w.botline -relief ridge -borderwidth 2 -height 2\n"); printf("\tpack $w.botline -side bottom -fill x\n\n"); /* * The "config" frame contains the canvas and a scrollbar. */ printf("\tframe $w.config\n"); printf("\tpack $w.config -fill y -expand on\n\n"); printf("\tscrollbar $w.config.vscroll -command \"$w.config.canvas yview\"\n"); printf("\tpack $w.config.vscroll -side right -fill y\n\n"); /* * The scrollable canvas itself, where the real work (and mess) gets done. */ printf("\tcanvas $w.config.canvas -height 1\\\n" "\t\t-relief flat -borderwidth 0 -yscrollcommand \"$w.config.vscroll set\" \\\n" "\t\t-width [expr [winfo screenwidth .] * 1 / 2] \n"); printf("\tframe $w.config.f\n"); printf("\tpack $w.config.canvas -side right -fill y\n"); printf("\n\n"); } /* * Each proc we create needs a global declaration for any global variables we * use.
