- These two units (Emouse and LObjects) form the Views library to create and manipulate graphic windows
- in Turbo Pascal (TP). This library IS NOT FREEWARE !!!!.
-
- If you find it usefull you can use it in your programs, I only ask two things in return:
-
- 1. Send me any changes that you make to the library (I mean the source code). In this way I can keep
- improving the library and everybody wins.
- This project is for the benefit of everyone who programs in TP and wants or needs to use graphic
- manipulations. You are encouraged to modify or add new code to the library, just keep me posted !!!.
- In fact, If you want to work in colaboration with me just let me know... Four hands work faster than two.

- 2. Any contributions are wellcome... (yes, I mean money). This helps me to update my TP compiler and keep
- this project going. I donot like to put a fixed price to this library, but I think that $30.oo US is a
- reasonable amount. When you send the money, make sure to include your address (physical and Email), in
- this way I can keep you posted about new releases or new objects included in the library. Any comments
- are wellcome too !!!!.

- 1. I do not save the area under the window, there is a limit on TP of 64 K for images and this is not
- enough for VGA and SVGA graphic modes. Instead I use the Viewport to redraw the regions of the screen
- that require so. Each window must send a paint message to the app.run loop indicating the rectangle
- area that needs to be repainted.
-
- 2. The heart of the library is the Event record, this is not an object. This record is used in a loop
- which will check for mouse events and keypresses. If you want to check for more events just add them
- to the record. Check Emouse.pas for details.
-
- 3. I do not use TP Readkey, this function can not catch keys like Cntrl-F1, etc. Instead I get the key
- directly from the keyboard buffer through INTERRUPT $16, SERVICES $2 AND $10, check Emouse.pas for
- details.
-
- 4. I used a pretty fast assembly routine to get mouse events from the mouse driver. This is interrupt driven.
-
- 5. You can create your own controls by deriving your objects from the LControl object. You must override the
- HandleEvent and Paint methods. The default methods do nothing.
-
- 6. The library do not support MDI (multiple document interface) yet... Give me some time and I'll get it going.
-
- 7. There are 12 mouse cursors included in the Emouse.pas unit. I'm working on a mouse editor that will allow
- the interactive (visual) creation of new mouse cursors.
-
- 8. The library do not support ICONS yet... My plans are to implement a visual editor that can create mouse cursors
- and icons and write the pascal constants to a file that you can later include in your program. This part might
- take a little while... so ... do not hold your breath. For this reason I did not implement the minimize (iconize)
- feature in the windows. Windows can be maximize and restore only.
-
- 9. This library is fully compatible with TP fonts and BGI drivers. You can use any of them.
-
- 10. There is A BIG BUG in clipping bit mapped fonts, they do not clip correctly. Use Stroked fonts when possible.
- Another BIG BUG is in clipping with the bar procedure. Sometimes the bar is not clipped correctly. Use the FillR
- method provided in the library to draw filled rectangles inside windows.
- I wonder when these people of Borland will give us a decent graphics library ?
