- Introduction.
-
- GTMOUSE is a Borland Pascal 6.0 & 7.0 Unit for mouse handling.
- GTMouse is not a mouse driver, it works over any standard mouse
- driver. If included it converts standard block mouse cursor in
- smoothly moving across the screen arrow-like mouse cursor in
- TEXT MODE of video adapter. This is similar to Norton Utilities
- 6.0, PCTools 7.0 and some others programs. GTMouse will make
- your application program much more attractive and professionally
- looking. This is possible only for EGA or VGA adapters, it don't
- do anything on others adapters.
-
- Initially developed for Borland's Turbo Vision package, it may
- be used with various TP mouse drivers, such as TurboPower
- Software's Object Professional, IdSoft D&M's MouseLib and
- others.
-
- News in version 1.4.
-
- - External Sleeper unit is included.
-
- File List.
-
- This package contains the following files.
-
- GTMOUSE6.TPU - TP 6.0 unit (rename to GTMOUSE.TPU)
- GTMOUSE.TPU - TP 7.0 unit
- GTMOUSE.TPP - BP 7.0 protected mode unit
- GTMOUSE.DOC - this file
- GTMOUSE.TXT - interface section of GTMouse.TPU
- GTMOUSE.REG - registration File.
- DARK.PAS - sleepre unit source
-
- TVBDEMO.PAS - simple Turbo Vision sample program with
- TVBDEMO.EXE GTMouse included. Slow modification of Borland's
- TVGUID14.PAS.
-
- OPDEMO.PAS - Object Professional Mouse sample with GTMouse included
- OPDEMO.EXE
-
- 1. Usage of GTMouse.
-
- Simply copy GTMOUSE.TPU file in your TPU direction and include
- GTMouse in use clause of your program
-
- uses GTMouse,...{any others TPUs};
-
- ATTENTION. The GTMouse must be the FIRST used TPU of program.
- More accuratly it must precede any TP mouse driver (such as
- Drivers of Turbo Vision package).
-
- Now recompile and run your program. You will see the arrow-like
- mouse cursor which is smoothly moving over the screen and
- changing with pushing of any mouse button. Besides this the
- behavior of your program doesn't have to change.
-
- You can use GTMouse without any additional calls, but they can
- improve your program.
-
- 1.1 Mouse Cursor Form Changing.
-
- GTMouse contains some predefined mouse cursor images.There are
- two procedures to select mouse cursor image
-
- SelectNotPressedImage(nmImage:ImageNames);
- SelectPressedImage(nmImage:ImageNames);
-
- for notpressed and pressed mouse button respectevly. Moreover
- you can make your own image and connect it with any ImageName by
- procedure
-
- LinkUserImageWith(nmImage:ImageNames,MyArrow:ImageArray);
-
- where ImageArray = array[0..15] of byte. Example of Cursor
- Image:
-
- Byte BitMap MyArrow
- 0 00000000 $00
- 1 01000000 $40
- 2 01100000 $60
- 3 01110000 $70
- 4 01111000 $78
- 5 01111100 $7c
- 6 01111110 $7e
- 7 01111000 $78
- 8 01101100 $6c
- 9 01001100 $4c
- 10 00001100 $0c
- 11 00001100 $0c
- 12 00000000 $00
- 13 00000000 $00
- 14 00000000 $00
- 15 00000000 $00
-
-
- 1.2 Activate and deactivate GTMouse.
-
- There are two procedures
-
- DoneGTMouse;
- InitGTMouse;
-
- to deactivate and reactivate GTMouse respectively.
-
- If your program use COMMAND.COM to start other programs or run
- DOS shell you must deactivate GTMouse before this and reactivate
- it after
-
- . . . .
- DoneGTMouse; {Deactivate GTMouse}
- SwapVectors;
- Exec(GetEnv('COMSPEC'),...);
- SwapVectors;
- InitGTMouse; {Reactivate GTMouse}
- . . . .
- At the program begining GTMouse activates automatically.
-
- 1.3 Reserved symbols.
-
- If you are using GTMouse there are eight symbols (from 256
- possible) which cann't be used to screen output. These symbols
- reserved by GTMouse to dynamically redefine their views to form
- graphics mouse cursor. By default they are (#01, #02, #03, #04,
- #208, #209, #215, #216). To replace them with any others use
-
- ChangeCursorArray(var mArray);
-
- where parameter is array[1..8] of chars. Last four characters
- must be in pseudo graphics range ($c0..$df), first four must not
- be in this range. Last demand connected with VGA peculiarities
- in text mode.
-
- 1.4 External Sleeper.
-
- Include Dark.TPU in use clause of your program
-
- uses GTMouse, Dark, ...{any others TPUs};
-
- Sleeper activates automatically with default params. You can
- reactivate it at any moment with
-
- InitSleeper(SlepType,nWaitTime,xUpLeft,yUpLeft,xDnRight,yDnRigth);
-
- where
- SleepType - 0..4 type of sleeping screen.
- nWaitTime is a no-event waiting time to sleep (in seconds),
- other params - screen region in which the occurance of mouse
- cursor cause the "sleeping" of program.
- The default is
-
- InitSleeper(4,30,80,1,80,1);
-
- You must include procedure call
-
- Sleeper;
-
- in any event waiting cycle of your program.
-
- To deactivate sleeper simply set variable SleepOn to FALSE.
-
-
- 2. About samples.
-
- TVBDEMO.EXE is not a special GTMouse sample, it is slightly
- modified Turbo Vision Guide example TVGUID14.PAS. Besides
- GTMouse we include only the possibility to change mouse cursor
- form (with Alt-H key or from status line). You can look also
- the modified windows and buttons views, to compare compile and
- run TVBDEMO.PAS with your compiler and Turbo Vision TPU's. This
- TVBDEMO.EXE has been compiled with our own version of
- TurboVision TPU's, all registered users of GTMouse can obtain
- them on special request.
-
- Others samples illustrate the technique of GTMouse usage with
- Object Professional and MouseLib packages. The main advise is to
- avoid any screen SCROLLs and screen SAVING/RESTORING with active
- mouse cursor, so your code must be something about
-
- . . . . .
- HideMouse; {call to hide mouse in your mouse driver}
- {Any screen changing code}
- ShowMouse;
- . . . .
-
- 3. Some recomendations.
-
- - deactivate GTMouse when use internal debugger of Turbo Pascal IDE;
-
- - deactivate GTMouse before any videomode change. GTMouse works
- with various screen text modes, simply reactivate it after mode
- changing.
-
- Important. Deactivate GTMouse in graphics modes.
-
- 4. Registration.
