<P>This version (0.82) of PgAccess introduce the visual form builder. |
||||
<P>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.</P> |
||||
|
||||
<P>For the moment, it has only some basic widgets : labels, entries, buttons |
||||
, listboxes , checkboxes and radiobuttons. |

, listboxes , checkboxes and radiobuttons.</P> |
||||
|
||||
<P>Also there is a pseudo query widget that allows you yo have access to |
||||
a query results. </P> |
||||
|
||||
<P><B>How do you generate widgets :</B></P> |
||||
|
||||
<OL> |
||||
<LI>select a widget from the toolbox by clicking the appropriate radiobutton</LI> |
||||
|
||||
<LI>move to the canvas , point with the mouse at the desired location and |
||||
click the mouse button to begin</LI> |
||||
|
||||
<LI>keeping the mouse-button pressed move the mouse in order to draw a |

rectangle that will hold the widget</LI> |
||||
|

<P>Also there is a query widget that allows you yo have access to a query |
||||
results. |
||||
<LI>release the mouse-button </LI> |
||||
</OL> |
||||
|
||||
<P>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. |
||||
<P>In the rectangle that you have designed it will appear the selected |
||||
object.<BR> |
||||
Move now to the attribute window to change some of its properties.</P> |
||||
|
||||
<P>Renaming, resizing items are possible (for the moment) only by modifying |
||||
appropriate parameters in attribute window. You <B>must </B>press Enter |
||||
in the edit field after changing a value in order to be accepted. </P> |
||||
|
||||
<P>You can also move items by dragging them or delete them by pressing |
||||
Del key. |
||||
Del key after selecting them.</P> |
||||
|
||||
<P>In attribute window, there are some fields named <B><TT><FONT SIZE=+1>Command |
||||
</FONT></TT></B>and <B><TT><FONT SIZE=+1>Variable</FONT></TT></B>. |
||||
</FONT></TT></B>and <B><TT><FONT SIZE=+1>Variable</FONT></TT></B>. </P> |
||||
|
||||
<P>The field <B><TT><FONT SIZE=+1>Command </FONT></TT></B>have meaning |
||||
only for Button widgets and holds the command that will be invoked when |
||||
the button is pressed. |
||||
|
||||
<P>The field <B><TT><FONT SIZE=+1>Variable </FONT></TT></B>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. |
||||
|
||||
<P>In order to make a simple test, put an entry field and set it's variable |
||||
to <B>v1</B> 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. |
||||
<BR>Another test is defining in Script module a script called "My first |
||||
script" having the following commands: |
||||
<BR><TT><FONT SIZE=+1>tk_messageBox -title Warning -message "This is my |
||||
first message!"</FONT></TT> |
||||
<BR>and then define a button who's command is <B><TT><FONT SIZE=+1>execute_script |
||||
"My first script"</FONT></TT></B>. |

<H2> |
||||
Database manipulation</H2> |
||||
Let's presume that our form have the internal name <B><TT>mf </TT></B>(my |
||||
form). He wil be referred inside the Tcl/Tk source as <B><TT>.mf</TT></B> |
||||
<BR>If you want to close the form in run-time you have to issue the command |
||||
<B><TT>destroy .mf</TT></B> |

the button is pressed. </P> |
||||
|
||||
<P> The field <B><TT><FONT SIZE=+1>Variable </FONT></TT></B>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 <B>t</B> and <B>f</B> (from |
||||
true and false) in order to simplify binding to logical data fields (PgAccess |
||||
0.82 used 0 and 1).</P> |
||||
|
||||
<P> 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.</P> |
||||
|
||||
<P> In order to make a simple test, put an entry |
||||
field and set it's variable to <B>v1</B> 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. <BR> |

Another test is defining in Script module a script called "My first |

<TT><FONT SIZE=+1>tk_messageBox -title Warning -message "This is my |

<BR> |
||||
If you want to close the form in run-time you have to issue the command |
||||
<B><TT>destroy .mf</TT></B> </P> |
||||
|
||||
<P>Also, any widget will have the name prefixed by <B><TT>.mf </TT></B> |

. |

. </P> |

|

<P>We can name the query widget <B><TT>qry</TT></B> for example. The complete |

name will be <B><TT>.mf.qry</TT></B> then. |

<BR>The <B><TT>Command </TT></B>property of the query widget must contain |

the SQL command that will be executed. |

<BR>When the form will be in run-time, automatically you will have acces |

the recordset |

<BR><TT>.mf.qry:movelast , .mf.qry:movenext , .mf.qry:moveprevious </TT>- |
||||
moves the cursor |
||||
<BR><TT>.mf.qry:updatecontrols</TT> - update the variables inside the designed |

form that have a particular name (I'll explain later) |

<BR><TT>.mf.qry:close</TT> - close the connection (<B><FONT COLOR="#FF0000">if |

you don't close the query result, you will loose memory</FONT></B>) |

name will be <B><TT>.mf.qry</TT></B> then. <BR> |

The <B><TT>Command </TT></B>property of the query widget must contain the |

SQL command that will be executed. <BR> |

When the form will be in run-time, automatically you will have acces to |

the following procedures and functions : </P> |
||||
|

query (returns nothing) <BR> |

<B><TT>.mf.qry:setsql newsql</TT></B> - set the command query that will |

be executed at the next <B><TT>.mf.qry:open<BR> |

.mf.qry:nrecords</TT></B> - returns the number of records in the selected |

<B><TT>.mf.qry:crtrecord </TT></B>- returns the current record number inside |

the query result<BR> |

<B><TT>.mf.qry:fields</TT></B> - returns a list of the fields in the result |

set <BR> |

<B><TT>.mf.qry:movefirst</TT></B> - move the cursor to the first record |

<TT><B>.mf.qry:movelast</B> , <B>.mf.qry:movenext</B> , <B>.mf.qry:moveprevious</B> |
||||
</TT>- moves the cursor there<BR> |
||||
<B><TT>.mf.qry:moveto newrecno</TT></B> - move the cursor to that new record |
||||
number (first is 0)<BR> |
||||
<B><TT>.mf.qry:updatecontrols</TT></B> - update the variables inside the |
||||
designed form that have a particular name (I'll explain later) <BR> |
||||
<B><TT>.mf.qry:clearcontrols</TT></B> - clear the variables inside the |
||||
designed form binded to a query result<BR> |
||||
<TT><B>.mf.qry:fill listbox field</B> </TT>- fill the named listbox (whole |
||||
widget name as <B><TT>.mf.listbox1</TT></B>) with the all the values of |

that field in the current queryresult<BR> |
||||
<B><TT>.mf.qry:close</TT></B> - close the connection (<B><FONT COLOR="#FF0000">if |
||||
you don't close the query result, you will loose some memory</FONT></B>) |
||||
</P> |
||||
|
||||
<P>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.</P> |
||||
|
||||
<P>If you want to bound some controls to the fields of the recordset, you |
||||
will have to name their associate variable like that : |
||||
|
||||
<P><TT>.mf.qry.salary</TT> to get the "salary" field , or <TT>.mf.qry.name</TT> |
||||
to get the "name" field. |
||||
|
||||
<P>It's simple, isn't it ? It's just like a new widget that have some properties |
||||
and methods that can be accesed. |
||||
<BR>Also, the name convention is just like in Tcl/Tk. |
||||
will have to name their associate variable like that : </P> |
||||
|
||||
<P><B><TT>mfqry(salary)</TT></B> to get the "salary" field , |
||||
or <B><TT>mfqry(name)</TT></B> 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.<BR> |
||||
<B><FONT COLOR="#FF0000">* WARNING *</FONT></B> 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.</P> |
||||
|
||||
<P><B><FONT SIZE=+1><FONT COLOR="#9400D3">QUESTION</FONT> : </FONT></B>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, <B><TT>mfqry:open</TT></B> and <B><TT>mfqry:updatecontrols</TT></B> |
||||
instead of <B><TT>.mf.qry:open</TT></B> and <B><TT>.mf.qry:updatecontrols</TT></B> |
||||
?</P> |
||||
|
||||
<P>The only advantage of <B><TT>.mf.qry:open</TT></B> 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 (<B><TT>.mf.qry.salary)</TT></B> |
||||
it might be possible to abandon that naming convention .</P> |
||||
|
||||
<P>Here it is a dumped <B><A HREF="formdemo.sql">sample database</A></B> |
||||
that contains a demo database. What should you do ?<BR> |
||||
Shift-click the above URL in order to download that tiny file (4 Kb). Create |
||||
a empty database and <B><TT>psql yourdatabase <formdemo.sql</TT></B></P> |
||||
|
||||
<P>You should find a single table called "phonebook" a form called |
||||
"Phone book" and another "A simple demo form".</P> |
||||
|
||||
<P>First of all enter and view the phonebook table in table view. Note |
||||
the fields and their values.<BR> |
||||
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.</P> |
||||
|
||||
<P>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.</P> |
||||
|
||||
<P><FONT COLOR="#000080">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 <B>no live connection</B> 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.</FONT></P> |
||||
|
||||
<P>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.</P> |
||||
|
||||
<P>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 ) </P> |

<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. |
||||
<BR>You can download <A HREF="libpgtcl.so">from here </A>a version already |
||||
compiled for Linux i386 systems. Just copy libpgtcl.so into your system |
||||
library director (/usr/lib) and go for it. One of the solutions is to remove |
||||
from the source the line containing <B>load 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>The sollution was proposed by H.P.Heidinger ( hph@hphbbs.ruhr.de) and |

it's very simple.</P> |

|

<P>If you look into PgAccess, you will find fonts declared as follows :</P> |

<P><TT>$ grep -e '-font' -i pgaccess.tcl<BR> |

-font -Adobe-Helvetica-Medium-R-Normal--*-120-*-*-*-*-*-* \<BR> |

-font -Adobe-Helvetica-Medium-R-Normal--*-120-*-*-*-*-*-* \</TT></P> |

|
||||
<P>It should be something like: -adobe-helvetica-medium-r-normal-*-*-120-*-*-*-*-iso8859-1</P> |

|

<P>You can achieve this by running the following script :</P> |
