+<H1>PgAccess - Scripts and Forms
+<HR WIDTH="100%"></H1>
+
+<P>Beginning with 0.70 version, I have introduced in PgAccess two new modules
+for operating with scripts and forms.</P>
+
+<P> This would give to PgAccess the power of creating
+application directly into PgAccess, defining new modules, procedures, forms
+and possibly making it a rapid development tool for PostgreSQL. The "scripts"
+and "forms" modules are using two new tables called pga_forms
+and pga_scripts. PgAccess take care of creating them if user is opening
+a new database and grant ALL permissions on them to PUBLIC. <BR>
+ Both scripts and forms are containing in fact sources
+of code written in Tcl/Tk and when the user has choose to "open"
+one of them, either by double-clicking in the main window or pressing the
+"Open" button PgAccess is searching for them in pga_forms or
+pga_scripts table, get the code and simply "<B>eval</B>" it !<BR>
+ Of course, when Designing a script, a simple text editor
+is opened and text is saved as is in pga_scripts table. When "designing"
+a form, a "form editor" that would be very similar with "Visual
+Tcl" would be invoked.</P>
+
+<P> This mechanism and the extremely versatile scripting
+mode of Tcl/Tk would give PgAccess a great power for creating end user
+application using PosgreSQL. The most important thing is that the user
+could call procedures and functions that I have used for building up PgAccess
+!</P>
+
+<H3>Forms</H3>
+
+<P> Forms are special Tcl/Tk source code that is used
+for creating windows and placing widgets inside it. When Tcl/Tk is "eval"
+them, a new window appears, with buttons as defined that could call "user
+defined scripts", "user defined procedures" or "internal
+PgAccess procedures".<BR>
+ For the moment, 0.70 version of PgAccess does not have
+a module for designing forms. It is intended to make an interface to the
+most powerful program of designing applications under Tcl/Tk , Visual Tcl
+, so it could handle forms designed to be used inside PgAccess.<BR>
+ Forms can hold all the widgets allowed in Tcl/Tk , buttons,
+check-boxes, radio-buttons, list-boxes, frames, canvases, etc. With these
+forms, you can control your application so PgAccess would become just a
+"shell", a startup point for you applications.</P>
+
+<H3>Scripts</H3>
+
+<P> Scripts are normal Tcl/Tk code that is interpreted
+by Tcl/Tk. You can define your own procedures inside a script called "Library"
+for example. You can call your procedures from within another script, from
+another procedure.<BR>
+ The most important thing is that you have total access
+to the PgAccess's core of functions and procedures used by me in building
+PgAccess as an application. Just write <B><TT><FONT COLOR="#000080">open_table
+"Your sample table"</FONT></TT></B> and you'll see the result.<BR>
+ If you are writing a script called "Autoexec"
+then it will be executed every time the database is opened. You can put
+inside different commands that you want to be executed such as : running
+scripts that would define your own procedures such as <B><TT><FONT COLOR="#000080">execute_script
+"My own procedure library"</FONT></TT></B> or open a form with
+<B><TT><FONT COLOR="#000080">open_form "Main window with menu buttons"</FONT></TT></B>
+, and so on.</P>
+
+<P>
+<HR WIDTH="100%"></P>
+
+<H2>Examples :</H2>
+
+<P>We would like to give you some examples for using forms and scripts.
+First of all, get your PgAccess 0.70 version NOW !</P>
+
+<P><IMG SRC="a_right.gif" HEIGHT=20 WIDTH=20> Define your first
+form. Remember, the form design module hasn't arrived yet :-( , so you
+will have to define your first form using an action query :<BR>
+1. Click on Query tab and press "New" button<BR>
+2. Enter "<TT>Generate my first form</TT>" in Query name field<BR>
+3. Copy and paste from your browser window into query definition area the
+next text :<BR>
+<BR>
+<TT>insert into pga_forms values('My first form',' set base .pga_win_1;
+if {[winfo exists $base]} { wm deiconify $base; return }; toplevel $base
+-class Toplevel; wm focusmodel $base passive; wm geometry $base 395x389+325+188;
+wm maxsize $base 1009 738; wm minsize $base 1 1; wm overrideredirect $base
+0; wm resizable $base 1 1; wm deiconify $base; wm title $base "User
+defined Form No.1"; button $base.b1 -command {execute_script "My
+first script"} -text "My first button" ; button $base.bexit
+-command {destroy [focus]} -padx 9 -pady 3 -text Exit ; place $base.bexit
+-x 340 -y 355 -anchor nw -bordermode ignore ; place $base.b1 -x 10 -y 10
+-anchor nw;'); </TT></P>
+
+<P>4. Press "Save query definition button" and then "Close"<BR>
+5. In the mai window, select by clicking the query "Generate my first
+form" and press "Open" button.</P>
+
+<P>Your query must have been executed without errors! If you will check
+now the "Forms" tab, you will find there your first form. Press
+"Open" button and enjoy it! For the moment, if you will press
+"My first button" you will get an error message. Of course :
+we haven't yet defined our first script ! </P>
+
+<P><IMG SRC="a_right.gif" HEIGHT=20 WIDTH=20> Defining our first
+script :<BR>
+1. Click on Scripts tab and pres "New" button<BR>
+2. Enter "My first script" in script's name field<BR>
+3. Enter the body as the script the following statements :<BR>
+<BR>
+<TT>MsgBox "Warning" "PgAccess unleashed!"<BR>
+open_table pga_scripts<BR>
+<BR>
+</TT>4. Press "Save" button then "Cancel"</P>
+
+<P>It's now the time to define our first library script. I am defining
+not because I need it. I could write directly in "My first script"
+the instructions for creating that warning window but I only wanted to
+show you how you can mix PgAccess script execution with Tcl/Tk code and
+so on.</P>
+
+<P><IMG SRC="a_right.gif" HEIGHT=20 WIDTH=20> Define our first
+library that will contain your "user defined" Tcl/Tk procedures
+and functions :<BR>
+1. Click on Scripts tab and pres "New" button<BR>
+2. Enter "My first library" in script's name field<BR>
+3. Enter the body of the script the following statements :<BR>
+<BR>
+<TT>proc MsgBox {title msg} {<BR>
+ tk_messageBox -title $title -message
+$msg<BR>
+}<BR>
+<BR>
+</TT>4. Press "Save" button then "Cancel"</P>
+
+<P><IMG SRC="file:/home/teo/a_right.gif" HEIGHT=20 WIDTH=20> Define
+our first autoexec script that will contain commands that will be executed
+when opening database :<BR>
+1. Click on Scripts tab and pres "New" button<BR>
+2. Enter "Autoexec" in script's name field<BR>
+3. Enter the body of the script the following statements :<BR>
+<BR>
+<TT>execute_script "My first library"<BR>
+open_form "My first form"<BR>
+<BR>
+</TT>4. Press "Save" button then "Cancel"</P>
+
+<P>Everything is OK now! You will have to exit PgAccess and enter it again
+opening the same database ! Voila , your first form will pop-up on the
+screen, a message box is displayed and after clicking Ok button the table
+pga_scripts will be opened in table viewer revealing what's inside ! With
+this occasion I have shown how you could open in table view mode a "pga_..."
+system table that is hidden by PgAccess in main view mode!</P>
+
+<P>I am stopping here, asking you to try this new features and sending
+me as more feed-backs as you can! What do you think about this new features
+? How would you like to be developed PgAccess in future ? In this
+moment, I am working in recoding the main part of PgAccess in order to
+give to the user more "system" functions that would help him
+creating new applications very easy.<BR>
+<BR>
+Remember : I'm waiting your messages at <A HREF="mailto:teo@flex.ro">teo@flex.ro</A>
+</P>
+
+<P>
+<HR WIDTH="50%"></P>
+
+<P>You will also have the ability of hiding the main window of PgAccess
+at the beginning of "Autoexec" script execution and showing it
+before destroying "My first form". For this example, delete the
+previously defined "My first form" and create it with another
+action query with this code :<BR>
+<BR>
+<TT>insert into pga_forms values('My first form',' set base .pga_win_1;
+if {[winfo exists $base]} { wm deiconify $base; return }; toplevel $base
+-class Toplevel; wm focusmodel $base passive; wm geometry $base 395x389+325+188;
+wm maxsize $base 1009 738; wm minsize $base 1 1; wm overrideredirect $base
+0; wm resizable $base 1 1; wm deiconify $base; wm title $base "User
+defined Form No.1"; button $base.b1 -command {execute_script "My
+first script"} -text "My first button" ; button $base.bexit
+-command {Window show .dw ; destroy [focus]} -padx 9 -pady 3 -text Exit
+; place $base.bexit -x 340 -y 355 -anchor nw -bordermode ignore ; place
+$base.b1 -x 10 -y 10 -anchor nw;'); <BR>
+<BR>
+</TT>This new one is just showing main window (.dw) before destroying the
+"user defined window" . <BR>
+Also make "Autoexec" script to show like this :<BR>
+<BR>
+<TT>execute_script "My first library"<BR>
+Window hide .dw<BR>
+open_form "My first form"</TT><BR>
+</P>
