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> +<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" is +invoked. + +<P> This mechanism and the extremely versatile scripting mode +of Tcl/Tk would give PgAccess a great power for creating end user application +using PostgreSQL. The most important thing is that the user could call +procedures and functions that I have used for building up PgAccess ! +<H3> +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, +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. See the <A HREF="forms.html">special +section concerning forms.</A> +<H3> +Scripts</H3> + 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 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> +<HR WIDTH="100%"> +<BR>Remember : I'm waiting your messages at <A HREF="mailto:teo@flex.ro">teo@flex.ro</A> + +<P> +<HR WIDTH="50%"> +</BODY> +</HTML> |
