- MakeScrn - a text screen painting utility

- REQUIRES: Turbo Pascal 5.x and the TurboPower Professional 5.0x libraries

- Ever wish you could quickly "paint" a text screen the way you can a graphics
- screen? And then save it in the TurboPower Professional "Packed Window"
- format for later use in a program?
-
- I came on board in a new job recently, as was handed a TP project that used
- over 50 different screens. Another programmer that was leaving the company
- had done about 15% of the screens already, and had done them the hard way -
- coding the actual TP and TPro screen manipulation procedures/functions to
- draw the screen in the program and then save the screen to packed format.
- She had taken at least a day per screen; juggling prompt positions, trying
- attributes, starting over when she decided it wasn't what she wanted or when
- one of the other programmers made a change to data formats or other info to
- be displayed on the screen, etc. I know there had to be a better way... here
- it is.
-
- MakeScrn is a simple little program provided in source format that allows you
- to draw frames, enter text, change attributes, move portions of the screen
- around and generally "paint" what you want using similar commands to what you
- will find in many graphics paint programs. Screens you create in the program
- can be saved to disk as a "packed screen" using the routines in the TurboPower
- Professional 5.0x libraries, and can be reloaded for further work.
-
- Certainly there are other features that could be added to the program, and
- "gee-whiz" changes that could be made to the existing routines (I'd like to
- add the ability to rubberband frames, for example.) I leave these for you
- to experiment with, for I hope this can be a learning tool as well as a
- functional program (that's why I provide it in source form only!)
-
- --------
-
- Here's a basic outline of the program:
-
- When you execute the program, you are presented with a blank screen and the
- menu of commands in the upper right-hand corner. Pressing the first char of
- the command name executes that command. The available commands are:
-
- C)hange attributes - Change the display attributes (foreground and background
- colors) for an area. You select the area to change by
- first "dropping anchor" in the upper-left corner of the
- area by moving the cursor to that spot and pressing
- [Enter] or [LeftButton], then use the cursor keys or
- mouse to move to the lower-right corner and press [Enter]
- or [LeftButton] to define the area. The area can be any
- region from a single character cell to the entire screen.
- Once the area is defined, a map of screen attributes is
- displayed; the hex numbers going down the side of the map
- are the background values, the hex numbers across the top
- are the foreground attributes. Enter a 2-digit hex value
- for the new attribute (background value first) at the
- prompt in the lower left corner of the screen and the
- area will change to that value. At any time during the
- process, you can press [Esc] or [RightButton] to abort
- the whole process.
-
- D)raw Frame - Makes it easy to frame a window. Just like the C)hange
- attribute command, you drop anchor at the upper left
- corner and then drop anchor again at the lower right
- corner; the frame will be drawn.
-
- E)rase Area - Erases all text characters from the area defined by
- dropping anchors. The underlying attributes are not
- changed.
-
- F)rame Chars - Allows you to change between the four common frame char
- sets.
-
- I)nput Text - Allows you to input text on the screen. The only editing
- command available is the backspace. Drop anchor where
- you want the text to start, and type. Press [Esc] or
- [RightButton] when complete.
-
- L)oad Screen - Loads an existing screen from a file. You are prompted
- for the name of the file. Note that you can automatically
- load a screen when you execute the program by providing
- its name on the command line.
-
- M)ove Area - Allows movement of a region of the screen from one X-Y
- location to another. Define the area by dropping anchors,
- then place the cursor at the upper left corner of the
- new location for the region and press [Enter] of [Left-
- Button] to move. The area is forced to within the cur-
- rent screen boundries.
-
- Q)uit - As its name implies, this exits the program. The current
- screen contents are NOT saved; be sure to use the S)ave
- Screen command if you need to do so.
-
- V)iew - Just hides the menu so you can see the entire screen.
- Pressing [Enter], [Esc], [LeftButton] or [RightButton]
- restores the menu.
-
- S)ave Screen - Saves the current screen to a file. You are prompted for
- the filename to save. This file will be in the Turbo
- Power "packed window" format for easy use in another
- program. NOTE: I recommend that you give the screen file
- a name that will make it easy to later incluude in a
- "packed screen library" using the other routines in the
- TpCrt unit.
