+PGACCESS 0.86 29 March 1998
================================
I dedicate this program to my little 4 year daughter Ana-Maria and my wife
for their understanding. I hope they will forgive me for spending so many
can manage your tables, edit them, define queries, sequences and
functions.

+I use Tcl/Tk because it's a powerful language, and it took me only
four days of hard work to get it as you see it now.
2.How to INSTALL ?
-You will need Tcl/Tk package, I am using now Tcl 7.6 and Tk 4.2. There
-are some problems running under Tcl/Tk 8.0 but I will soon fix them.
+You will need Tcl/Tk package, I am using now Tcl 7.6 and Tk 4.2.
+PgAccess is running also on Tcl/Tk 8.0
Also, you will need the PostgreSQL to Tcl interface library, lined as a
Tcl/Tk 'load'-able module. It is called libpgtcl and the source is
You run it with the command:
- wish -f pgaccess.tcl
+ wish -f pgaccess.tcl [database]
+
+[database] is optional.
Another way of loading the PostgreSQL library is running it with pgwish.
It's a wish compiled with libpgtcl library so it could understand the

Tables
-- opening tables for vieweing, max 200 records
+- opening tables for viewing, max 200 records
- column resizing by dragging the vertical grid lines
- text will wrap in cells now
- dynamic row height when editing
- editing in place, double click the text you want to change
- record deleting , point the record, press Del key
- adding new records ,save new row with right-button-click on table for the moment
-- table generator assistant lizzard :-) (not wizzard)
+- table generator assistant
- table renaming and deleting (dropping)
- table information retrieving : owner, field information, indexes
- save view layout
- can store queries as views
- execution of queries
-- vieweing of select type queries result
+- viewing of select type queries result
- running action queries (insert, update, delete)
- visual query builder with drag & drop support, table aliasing
Forms
- open user defined forms
- form design module available
-- query widget allowing access to a recordset
+- query widget allowing access to a record set
Scripts
- define, modify and call user defined scripts
- table design (add new fields, renaming, etc)
- sequence and function renaming
-- more powerfull report generator and viewer
+- more powerful report generator and viewer
- help on line
6. How you should report the errors?
First of all : operating system, PostgreSQL version,Tcl/Tk version.
-A more detailed story of what have you done when error had occured.
+A more detailed story of what have you done when error had occurred.
Tcl/Tk stops usually with a error message and there is a button there
"Stack Trace" and if you press it, you will see a detailed information

Some information about table structure, no. of fields, records would
be also good.

-<P>Also, you will need the PostgreSQL to Tcl interface library, lined as
-a Tcl/Tk 'load'-able module. It is called libpgtcl and the source is located
-in the PostgreSQL directory /src/interfaces/libpgtcl. Specifically, you
-will need a libpgtcl library that is 'load'-able from Tcl/Tk. This is technically
-different from an ordinary PostgreSQL loadable object file, because libpgtcl
-is a collection of object files. Under Linux, this is called libpgtcl.so.

-You can download <A HREF="libpgtcl.so">from here </A>a version already

-libpgtcl.so </B>and to load pgaccess.tcl not with wish, but with pgwish
-(or wishpg) that wish that was linked with libpgtcl library! </P>

Forms</H3>
Forms are used for creating windows and placing widgets inside

+it. When PgAccess interpret them, a new window appear, with buttons as
defined that could call "user defined scripts", "user defined procedures"
or "internal PgAccess procedures".
<BR> Forms can hold all the widgets allowed in Tcl/Tk , buttons,
example. You can call your procedures from within another script, from
another procedure.
