Hi friends.
After some commits, TEXBOX object doesn't work properly.
I'm using this code:

Code: Select all

            WITH OBJECT TEXTBOX():New( "fshfemacm" )
               :Row           := 90
               :Col           := 560
               :Width         := 100
               :Height        := 20
               :DataType      := TXT_NUMERIC
               :Value         := 0
               :ToolTip       := "Enter valid cm"
            END WITH

I can't insert ".34", "-.2": in other words "." can't be accepted.

TEXTBOX is a foundamental object and it is very hard to manage: I know.

Some times ago, I sent to Francesco my POW about TEXTBOX (without usage of VALID and WHEN clause). It's an experiment, running experiment, but (I think) it can be considered a good way (to improve).

I used this logic:

• A) data type must be a parameter when TEXTBOX object was created. There isn't problem with HMG3 command because value is known (TEXT by default, NUMERIC or DATE if present).
  With HMG4, New method will be TEXTBOX():New( cName, oParent, nDataType ). All parameters can be optional; when numeric or date value must be managed, TXT_NUMERIC or TXT_DATE must be inserted.

• B) when mask present, there is a translations from Clipper style to Qt style and setinputmask (Qt property about QlineEdit) it will be used.
  In other words, like Clipper "@999,999.99 999,999.99": "@999,999.99" as I want see and "999,999.99" as I can insert.

• C)If mask not present, input follows another way

Anyway, this is not important.

I think all of us must investigate to find a solution for this object (and, if needed, losing some HMG3 backward compatibility).

Cheers

* source/animatebox.prg
+ added method Center for HMG3 compatibility.

Code: Select all

2011-11-30 17:05 UTC+0100 Ricci Zepmeusel ( ricci at conzoft.de )
   * source/animatebox.prg
     - deleted method Center 
   * include/hmg.ch
     ! [:Alignment   := if ( <.lCenter.> , LBL_CENTER, LBL_LEFT ) ];;
       in #command ANIMATEBOX for HMG3 compatibility.

Instead of creating a useless method (it has no function), it´s be better to use the existing center command from the parent of animatebox.
Now @ x,y ANIMATEBOX .... CENTER is working!

For the oneliner please use ALIGNMENT CENTER

     + Implemented HARD VALID (clones of harbour GET VALID)
       Please read the message on the developers forum

I will open a new thread to comment on this.

   * source/textbox.prg
     + Added QValidator support. It can work as a PICTURE alternative using
       reg-exp definitions. A lot of web sites collect these definitions.
       It works differently to PICTURE so it is not a replacement but an
       alternative.
   * samples/validation/demo_1.prg
     * little sample

some readings about reg-exp:
- http://doc.qt.nokia.com/qq/qq01-serious ... egexp.html actually the paragraph title "VALIDATION"... unfortuantely we can't create IsbnValidator class at prg level, only in c++
- http://www.regexlib.com/?AspxAutoDetectCookieSupport=1 a massive collection of reg-exp for different data types... of which the following is a section:
- http://regexlib.com/DisplayPatterns.asp ... eSupport=1 list of patterns for numbers/currencies and numerics in general... a PICTURE "99999.99" may be translated into regexp \d{1,5}(\.\d{1,2})? and then Qt takes care of it..
(syntax may differ in Qt)
- http://www.aspnetajaxtutorials.com/2010 ... meric.html for dates


IT IS NOT A "PICTURE" ALTERNATIVE: it works differently on screen !!!

   * source/textbox.prg
     * Removed the WITH OBJECT Self stuff... it has some side-effects and
       must be implemented a bit differently...

   * samples/validator/validator.prg
     * it's a basic program to test and compare different Validator
       expression. In the combobox select the RegExp you want to test
       and modify them to experiment. Press button to open a non-modal
       window that will permit to actively compare multiple RegExp.
       To do: RegExp name, value and longer description (not present now)
       should be kept in a separate file and read at program startup so
       that everybody can populate it with his own test RegExps.

Anybody wishing to complete it ?
