* 65.asm TLtabs version 0.01 8.6.97 include 'Front.i' ; ***** Important notes about this Program ***** ; TLtabs is used to draw a set of thumbtab cards on a window, and monitor ; them. tandem.library has several sets of routines like this: ; - TLtabs,TLtabmon - for a set of thumbtab cards ; - TLslider,TLslimon - for a slider ; - TLscroll - for a window scroller ; - TLbutprt,TLbutmon - for a set of buttons ; Unlike tandem.library requesters, which take over everything and use their ; own window, the above are rendered on a window with other things, and ; share the window. You can of course use gadtools.library gadgets, which ; are sophisticated, as each gadget sends its own special IDCMP messages to ; you. But tandem.library requires you to monitor each TLkeyboard you get, ; to see if the input is from any of the above. ; Follow the logic of the program below to see how you do this. You first ; set up a set of tab cards, & decide what you will do in each. You can of ; course have all sorts of other things on the window. Basically, the user ; is expected to click things to activate them, so what your program must ; do, is see what gets clicked, and activate it for the user, until ; something else gets clicked. ; The program below sets up a set of 4 tab cards, which do various things. ; You will see how to go from card to card under user control (by clicking ; thumb tabs), or under program control. You will see how to edit strings on ; a tab card, how to use buttons, &c. ; You will see that this program uses a set of 12 tiny grafix which you can ; show with TLpict - these are useful for all sorts of things, but they ; are inflexible in that TLpict doesn't allow you to specify the pens used ; to draw them. The grafix allow rounded corners on a bevelled box, arrows ; pointing in 4 directions, a checkmark and a tiny tandem.library logo. ; I didn't make this program font-sensitive, or it would have been too long ; and messy to take in easily. wdth: EQU 160 ;tabcard minimum body width (20 chrs) hght: EQU 120 ;tabcard body height xpos: EQU 20 ;tabcard xpos ypos: EQU 10 ;tabcard ypos ;data for tabs tab: ds.w 1 ;currently operative tab ;tab1 data rec: ds.w 1 ;-1recessed,0normal t1ps: ds.w 2 ;bev box posn ;tab2 data name: ds.b 20 ;name as entered strings: dc.b 0 st_1: dc.b 'TLTabs demonstration',0 ;1 dc.b 'Abc\Defg\Hij\Klmn',0 ;2 dc.b 'I am Tab card Abc!',0 ;3 dc.b 'I am Tab card Defg!',0 ;4 dc.b 'I am Tab card Hij!',0 ;5 dc.b 'I am Tab card Klmn!',0 ;6 dc.b 'TLpict icons 0-B...',0 ;7 dc.b '0 1 2 3 4 5 6 7',0 ;8 dc.b '8 9 A B C D E F',0 ;9 dc.b 'Click the box',0 ;10 dc.b 'for a shriek',0 ;11 dc.b 'for a query',0 ;12 dc.b '!',0 ;13 dc.b '?',0 ;14 dc.b 'Enter your name...',0 ;15 dc.b 'Name',0 ;16 dc.b 'Quit',0 ;17 dc.b 'Art!',0 ;18 dc.b 'Go to Tabcard Abc',0 ;19 ds.w 0 * demonstrate TLtabs Program: TLwindow #0,#0,#0,#380,#120,#640,#256,#-1,#st_1 ;open window 0 beq Pr_quit clr.w rec ;initialise data clr.b name TLtabs #2,#wdth,#hght ;set up tabs: heders in string 2, body 160X120 Pr_draw: TLtabs #0,#1,#xpos,#ypos ;draw with tab1 active move.l xxp_AcWind(a4),a5 ;a5 is currently popped window } used by moveq #xpos+4,d6 ;d6 is lhs of printable area of body } T1render moveq #ypos+1,d7 } add.l xxp_tblh(a4),d7 ;d7 is top of printable area of body } bsr T1render ;draw tab1 Pr_wait: TLkeyboard ;get keyboard Pr_pick: TLwupdate cmp.b #$1B,d0 ;quit if Esc beq Pr_quit cmp.b #$93,d0 ;quit if Close window beq Pr_quit ******* ;note: we would monitor for other things on the ******* ;window here, if there were other things on it. ******* ;If yes, process them, & go to Pr_wait. move.l xxp_AcWind(a4),a5 ;a5 is currently popped window moveq #xpos+4,d6 ;d6 is lhs of printable area of body moveq #ypos+1,d7 add.l xxp_tblh(a4),d7 ;d7 is top of printable area of body move.l d0,d4 ;save d0 cmp.b #$80,d0 ;only call TLtabmon if left mouse button bne.s Pr_cont ;else go monitor whichever tabcard at front TLtabmon d1,d2,#xpos,#ypos ;see if thumbtabs clicked beq.s Pr_cont ;no, go monitor whichever tabcard at front move.w d0,tab ;yes, note which tab is now operative cmpi.w #2,d0 ;go draw whichever thumbtab clicked bcs Pr_t1dr beq Pr_t2dr cmpi.w #4,d0 bcs Pr_t3dr bra Pr_t4dr Pr_cont: move.l d4,d0 ;restore d0 from TLkeboard sub.w xxp_LeftEdge(a5),d1 ;make lmb relative to window printable area sub.w xxp_TopEdge(a5),d2 cmpi.w #2,tab ;branch to whichever tab bcs Pr_tab1 ;(each test if the TLKeyboard is relevent to it) beq Pr_tab2 ;(if so, they act upon it, else discard it) cmpi.w #4,tab bcs Pr_tab3 bra Pr_tab4 Pr_t1dr: ;draw tab1 bsr T1render bra Pr_wait Pr_t2dr: ;draw tab2 bsr T2render bra Pr_wait Pr_t3dr: ;draw tab3 bsr T3render bra Pr_wait Pr_t4dr: ;draw tab4 bsr T4render bra Pr_wait Pr_tab1: ;monitor tab1 bsr T1monitor bra Pr_wait Pr_tab2: ;monitor tab2 clr.l xxp_kybd(a4) ;clear in case Reqedit ends with click bsr T2monitor ;do the monitoring tst.l xxp_kybd(a4) ;was there a click? beq Pr_wait ;no, wait for one bra.s Pr_ccyc ;yes, get it as an input Pr_tab3: ;monitor tab3 (sets EQ if quit requested) bsr T3monitor beq Pr_quit ;go if quit requested bra Pr_wait Pr_tab4: ;monitor tab4 bsr T4monitor bra Pr_wait Pr_ccyc: ;process a keyboard input inherited from move.l xxp_kybd(a4),d0 ; monitoring a page move.l xxp_kybd+4(a4),d1 move.l xxp_kybd+8(a4),d2 cmp.b #$1B,d0 ;(don't quit from here if Esc) bne Pr_pick clr.b d0 bra Pr_pick Pr_done: ;clear tabs area & quit (Esc or close window) TLtabs #0,#0,#xpos,#ypos Pr_quit: rts * render tab1 T1render: TLreqarea d6,d7,#wdth,#hght,#3 ;clear display area in case re-calling move.l xxp_AcWind(a4),a5 ;print title move.w #$0203,xxp_FrontPen(a5) TLstring #3,d6,d7 subq.b #1,xxp_FrontPen(a5) move.l d7,d2 ;print string 10 add.w #20,d2 move.l d6,d1 TLstring #10,d1,d2 tst.w rec ;go if recessed bmi .t1rc addq.w #8,d2 ;'for a shriek...'
