FORMS

This version (0.82) of PgAccess introduce the visual form builder. +

This version (0.83) of PgAccess has changed a little the visual form +builder introduced since 0.82 version : variable handling, query-results +interface and control bindings naming convention. Please read it carefully, +download the database demo and practice a while before trying to design +your own forms.

For the moment, it has only some basic widgets : labels, entries, buttons -, listboxes , checkboxes and radiobuttons. +, listboxes , checkboxes and radiobuttons.

+ +

Also there is a pseudo query widget that allows you yo have access to +a query results.

+ +

How do you generate widgets :

+ +
    +
  1. select a widget from the toolbox by clicking the appropriate radiobutton
    2. + +
  2. move to the canvas , point with the mouse at the desired location and +click the mouse button to begin
    3. + +
  3. keeping the mouse-button pressed move the mouse in order to draw a +rectangle that will hold the widget
    4. -

    Also there is a query widget that allows you yo have access to a query -results. +

  4. release the mouse-button
    5. +
-

In a manner very similar with Visual Tcl or Visual Basic, the user must -select a widget from the toolbar and drags on the canvas the rectangle -that would define the widget. It can also specify some attributes in a -separate window. Renaming, resizing items are possible modifying parameters -in attribute window. Do not forget to press Enter in the edit field after -changing a value in order to be accepted. +

In the rectangle that you have designed it will appear the selected +object.
+Move now to the attribute window to change some of its properties.

+ +

Renaming, resizing items are possible (for the moment) only by modifying +appropriate parameters in attribute window. You must press Enter +in the edit field after changing a value in order to be accepted.

You can also move items by dragging them or delete them by pressing -Del key. +Del key after selecting them.

In attribute window, there are some fields named Command -and Variable. +and Variable.

The field Command have meaning only for Button widgets and holds the command that will be invoked when -the button is pressed. - -

The field Variable have meaning -only for EditField , Label widgets and checkboxes and it is the name of -the global variable that will hold the value for that widget. For checkboxes -the values are 1 or 0. - -

In order to make a simple test, put an entry field and set it's variable -to v1 and a button who's command is "set v1 whisky". Press the button -"Test form" and click on the button. In that entry should appear whisky. -
Another test is defining in Script module a script called "My first -script" having the following commands: -
tk_messageBox -title Warning -message "This is my -first message!" -
and then define a button who's command is execute_script -"My first script". -

-Database manipulation

-Let's presume that our form have the internal name mf (my -form). He wil be referred inside the Tcl/Tk source as .mf -
If you want to close the form in run-time you have to issue the command -destroy .mf +the button is pressed.

+ +

    The field Variable have +meaning only for EditField , Label widgets , checkboxes and radiobuttons +and it is the name of the global variable that will hold the value for +that widget. For checkboxes the values are t and f (from +true and false) in order to simplify binding to logical data fields (PgAccess +0.82 used 0 and 1).

+ +

    For radiobuttons, it is usual to assign the +same variable to the same radiobuttons within the same group. That variable +will contain the name of the widget of the radiobutton that has been pressed. +Let's presume that you have entered 3 radiobuttons named red, green and +blue, all of them having the same variable named color. If you will press +them, they will assign their names to global variable.

+ +

    In order to make a simple test, put an entry +field and set it's variable to v1 and a button who's command is +"set v1 whisky". Press the button "Test form" and click +on the button. In that entry should appear whisky.
+Another test is defining in Script module a script called "My first +script" having the following commands:
+tk_messageBox -title Warning -message "This is my +first message!"
+and then define a button who's command is execute_script +"My first script".

+ +

Database manipulation

+ +

Let's presume that our form have the internal name mf (my +form). He will be referred inside the Tcl/Tk source as .mf +
+If you want to close the form in run-time you have to issue the command +destroy .mf

Also, any widget will have the name prefixed by .mf      We will have .mf.button1 or .mf.listbox1 -. +.

We can name the query widget qry for example. The complete -name will be .mf.qry then. -
The Command property of the query widget must contain -the SQL command that will be executed. -
When the form will be in run-time, automatically you will have acces -to the following methods : - -

.mf.qry:execute - opens the connection and execute the query -(returns nothing) -
.mf.qry:nrecords - returns the number of records in the selected -query -
.mf.qry:fields - returns a list of the fields in the result -set -
.mf.qry:movefirst - move the cursor to the first record in -the recordset -
.mf.qry:movelast , .mf.qry:movenext , .mf.qry:moveprevious - -moves the cursor -
.mf.qry:updatecontrols - update the variables inside the designed -form that have a particular name (I'll explain later) -
.mf.qry:close - close the connection (if -you don't close the query result, you will loose memory) +name will be .mf.qry then.
+The Command property of the query widget must contain the +SQL command that will be executed.
+When the form will be in run-time, automatically you will have acces to +the following procedures and functions :

+ +

.mf.qry:open - opens the connection and execute the +query (returns nothing)
+.mf.qry:setsql newsql - set the command query that will +be executed at the next .mf.qry:open
+.mf.qry:nrecords - returns the number of records in the selected +query
+.mf.qry:crtrecord - returns the current record number inside +the query result
+.mf.qry:fields - returns a list of the fields in the result +set
+.mf.qry:movefirst - move the cursor to the first record +in the recordset
+.mf.qry:movelast , .mf.qry:movenext , .mf.qry:moveprevious +- moves the cursor there
+.mf.qry:moveto newrecno - move the cursor to that new record +number (first is 0)
+.mf.qry:updatecontrols - update the variables inside the +designed form that have a particular name (I'll explain later)
+.mf.qry:clearcontrols - clear the variables inside the +designed form binded to a query result
+.mf.qry:fill listbox field - fill the named listbox (whole +widget name as .mf.listbox1) with the all the values of +that field in the current queryresult
+.mf.qry:close - close the connection (if +you don't close the query result, you will loose some memory) +

+ +

It's no need to close a query-result if you want to assign it a new +SQL command and open it again. That will be done automatically.

If you want to bound some controls to the fields of the recordset, you -will have to name their associate variable like that : - -

.mf.qry.salary to get the "salary" field , or .mf.qry.name -to get the "name" field. - -

It's simple, isn't it ? It's just like a new widget that have some properties -and methods that can be accesed. -
Also, the name convention is just like in Tcl/Tk. +will have to name their associate variable like that :

+ +

mfqry(salary) to get the "salary" field , +or mfqry(name) to get the "name" field. So, you +take the internale name of the form (without the leading point) and merge +it with the query-widget name and you will get a associative arrayname. +The values are given using the field name as a key in this associative +array.
+* WARNING * The naming style has been +changed from 0.82 version of PgAccess and I cannot guarantee that it not +be changed again in the future. I'm just trying to make it as simple it +could be. The old style naming convention had some incompatibilities with +Tcl/Tk syntax.

+ +

QUESTION : Do +you think that it would be more clear if the above functions and procedures +regarding a query-widget would be named in a similar manner as binded variable +controls ? That mean, mfqry:open and mfqry:updatecontrols +instead of .mf.qry:open and .mf.qry:updatecontrols +?

+ +

The only advantage of .mf.qry:open is that is much closer +to the Tk method of referring objects within a window and it may give to +the programmer the feeling that he is using a object-oriented widget. Since +I cannot use further for naming binded variables a similar manner (.mf.qry.salary) +it might be possible to abandon that naming convention .

+ +

Here it is a dumped sample database +that contains a demo database. What should you do ?
+Shift-click the above URL in order to download that tiny file (4 Kb). Create +a empty database and psql yourdatabase <formdemo.sql

+ +

You should find a single table called "phonebook" a form called +"Phone book" and another "A simple demo form".

+ +

First of all enter and view the phonebook table in table view. Note +the fields and their values.
+Open the "Phone book" form and enter a letter (a, e or i) in +the field to the left of "Find" button then press Find. It's +fine to enter one letter in order to get more records in query result. +You will get information about the number of records selected, in the listbox +you will see all the values of field "name" from the current +data set. Use buttons to move to first, next, previous or last record within +the record set.

+ +

In order to add a new record, press the "New" button in order +to get new, clean entries. Fill them with your data and press "Add +new" button. A new phonebook record will be added. Also, if you want +to update a record, change it's values in the displayed fields after finding +it and press "Update" button. The values will be updated in the +database BUT NOT IN THE CURRENT QUERY RESULT . If you want to see them +modified, make a new query trying to find it again.

+ +

Before using the results from a query you should +know that the information that has been retrieved could be found only in +your computer client memory. It has no live connection to the data +from the database. That's why it isn't possible to develop a simple update +function as interface to that query-result widget. More than that : a query +result could be obtained from a SQL command that return a non-updatable +data set !!! For example fields gathered from multiple tables or summary +fields. It isn't just simple to make an automatic update procedure. The +programmer must know how to make the update or the append procedure, sometimes +using key fields to point to the desired record or an OID. There are examples +in the demo database in "Phone book" form. It may be possible +that in the future, I will develop another pseudo-widget describing a table. +It would be more simple than to implement an update or append or even a +delete procedure.

+ +

There is in the demo database also another simple form called "A +simple demo form". It will show you how to handle variables from checkboxes, +radiobuttons, how to use listboxes, open another forms and so on. I think +they will help you.

In order to avoid naming user defined forms with  a particular name of another PgAccess form, I would recommend naming them as udf0, udf1 -(user defined form 0 , 1 ) +(user defined form 0 , 1 )

KEEP IN MIND !       THE +FORM API WILL CHANGE IN ORDER TO BE MORE SIMPLE AND BETTER!    SEND +ME YOUR WISHES, YOUR IDEAS, YOUR OPINIONS !
+ALSO ... DON'T BLAME ME IF YOU WILL HAVE TO RE-DESIGN YOUR OLD FORMS DUE +TO SOME INCOMPATIBILITIES WITH NEWER PGACCESS VERSIONS.

    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 from here a version already -compiled for Linux i386 systems. Just copy libpgtcl.so into your system -library director (/usr/lib) and go for it.

    Special locale characters and PgAccess +

    + +

    The problem is related with some special characters used in different +countries because PgAccess did not use fonts with `-ISO8859-1' encoding +--

    + +

    The sollution was proposed by H.P.Heidinger ( hph@hphbbs.ruhr.de) and +it's very simple.

    + +

    If you look into PgAccess, you will find fonts declared as follows :

    + +

    $ grep -e '-font' -i pgaccess.tcl
    +-font -Adobe-Helvetica-Medium-R-Normal--*-120-*-*-*-*-*-* \
    +-font -Adobe-Helvetica-Medium-R-Normal--*-120-*-*-*-*-*-* \
    +-font -Adobe-Helvetica-Medium-R-Normal--*-120-*-*-*-*-*-* \
    +-font -Adobe-Helvetica-Medium-R-Normal--*-120-*-*-*-*-*-* \

    + +

    It should be something like: -adobe-helvetica-medium-r-normal-*-*-120-*-*-*-*-iso8859-1

    + +

    You can achieve this by running the following script :

    + +

    #!/bin/sh
    +cp pgaccess.tcl pgaccess.tcl-org
    +cat pgaccess.tcl |\
    +sed -e's/\-\*\-\*\ /\-iso8859\-1\ /g' |\
    +sed -e's/\-\*\-\*\}/\-iso8859\-1}/g' |\
    +sed -e's/\-\*\-\*\]/\-iso8859\-1]/g' |\
    +sed -e's/\-\*\-\*$/\-iso8859\-1/g' |\
    +sed -e's/\-Clean\-/\-Fixed\-/g' |\
    +sed -e's/clean/fixed/g' >pgaccess.iso
    +mv pgaccess.iso pgaccess.tcl
    +chmod +x pgaccess.tcl

    + +

    The final version of PgAccess (1.0) will let the user decide what fonts +will be used through a "preferences" dialog window.
