Pro's and Contra's fom Resources or Coded screens

[Marc Venken]

What is the general opinion for using Resources or coding screens ?

I see both many times passing in this Forum. Is there a Rule, or just as often, it is the like/dislike of the programmer.

[Carlos Mora]

IMHO, Resources have the advantage of being visually designed. Coding, that is made by hand, requires lots of trial and error. May be with practice you get fluent coding screens, but reading code you are not aware of how the form looks like.
In the other hand, the absolute coordinates systems in which the Windows dialog system is based on doesn't helps to deal with the different screen resolutions out there, it would be better sth like the one used by gtk. I think someone in this forum made some layout controls that mimics the behavior.
My personal option is resources, because it helps somehow to keep certain separation between the presentation layer and the business rules.

Hi

Resources of course. Why ? Time and effort. And at the end the results is the same

[hmpaquito]

Hi,

Coding... of course, but ! a long time I designed relative screen position commands for to help to coding screens:

(R) = RELATIVE

Code: Select all

@ RSAY "Customer"
@ RGET oRec:Code

@ RSAY "Name" ;
    SEPARATOR
    
@ RGET oRec:Name

FEED RSAY

@ RSAY "Address"
@ RGET oRec:Address

For normal app development resources is far more comfortable. For special tool development (like data driven forms) coding is required. As usual, having both technique available is the best thing for a developer (thank you FWH!).

@hmpaquito
Hello,
can you please explain your (R) = RELATIVE.
This looks very interesting to me.

@ others in favour of resources.
How can you resolve the different formfactors and how to program "METRO" style.

Thanks in advance
Otto

on win7 many lose of resource and I made only @x,y
I put on res only the bmps

I used the @ commands with dBase / Clipper for DOS. However, I never found a way to get consistent results with the @ commands under windows. I would love to use them, but my forms are very filled, and spacing is critical. I use Resources and have everything spaced uniformly. I can specify the exact size, and I use 20 pixel spacing between fields horizontally, and 5 pixel spacing between rows vertically.

I would love to use @ commands, but I have yet to see anything that shows us how to get the spacing correctly. It seems to vary based on the type of control. I need to handle labels, gets, dropdowns, checkboxes, browses, bitmap bars, etc.

Sometimes if I say @ 5,5, then I cannot now use @ 6,5. They overlap. Maybe someone could write a tutorial on how to get these uniform. I'd love it.

With that said, I do have some popups where I can use these, but it is all trial and error. Also, I find that differing controls can vary in height which looks rather poor to the client.

Marc:

I think, the best way is that you feel more comfortable.

hmpaquito,


are you willing to share your relative screen position commands / technique with us? Like Otto I'm very interested too!

[hmpaquito]

gkuhnert,

My technique about design form with code use extensivity preprocessor for hide design machine.

Cuore is ?

New Commands based in fwh commands.... is a new GUI


Problems ?

At begin was very hard design all commands.


How do it do ?

All is relative positions and sizes. So insert new says or get is very easy.

Code: Select all

hmpaquito,
thank you very much. I will try, see and learn

[Antonio Linares]

You can easily use relative coordinates this way:

Code: Select all

#include "FiveWin.ch"

function Main()

   local nRow := ScreenHeight() / 80
   local nCol := ScreenWidth() / 120
   local oDlg, cName := Space( 10 ), cAddress := Space( 15 )

   DEFINE DIALOG oDlg SIZE nCol * 30, nRow * 20
   
   @ nRow * 1.2, nCol * 2 SAY "Name:" OF oDlg PIXEL

   @ nRow * 1, nCol * 5 GET cName OF oDlg PIXEL

   @ nRow * 3.2, nCol * 2 SAY "Address:" OF oDlg PIXEL

   @ nRow * 3, nCol * 5 GET cAddress OF oDlg PIXEL

   ACTIVATE DIALOG oDlg CENTERED

return nil

[Marc Venken]

Use both systems will be best. In my 16 bit version I use these from recources : (preparing conversion to FWH)





But as Otto asked, These cannot by resized on the fly?

If I want to pimp design (More color and so) that is not done in (Pelles), but with code changing the object as far as I see code ?

Larger screens will be Recources
Little = coding.

Thanks for all replies.

Marc,

Larger screens = Resources
Little = Resources
