Drawing a rectangle around a data field

[Proman Rodi]

 Posted by:  Proman Rodi 

Hi, I'm trying to add a solid border to the standard data field border
(here the sample: http://i9.tinypic.com/68cveqa.jpg) and build a new
data field class with "double" border.

Tried to draw the solid border in WM_NCPAINT section but I lost the
original border, any idea or sample?

Thank you in advance

Hi,

I would try following:

Code: Select all

On WM_NCPAINT
    Call DefWindowProc( hWndItem, WM_NCPAINT, wParam, lParam )
    Call DrawExtraBorder()    ! in your class or somewhere else or inline
    Return 0

It works (I've used DefWindowProcA instead of DefWindowProc) perfectly!

Thank you Jarmo for the quick reply

Attached the sample in TD 3.0

PS 1: I've found a strange behavior of the class when the data field is
hidden by other window and then visible: the repaint function doesn't
paint correctly the original border. Any ideas?

PS 2: how to paint a red solid border around the data field with more
pixel of distance from the original border (a bigger red rectangle)?

Thank you!

It works but I've found a strange behaviour, take a look at the reply
and attached sample given to Mr. Alberto Aviles.

Hi
Call DefWindowProc( hWndItem, WM_NCPAINT, wParam, lParam ) ????
Why did you use this? (I do not understand this function correctly and all
subclassing but I think there is no reason to use it in this case)
There is a nice post about borders from 5/18/2007 by Christian Astor so
you can follow it.
Comment this line and test it :)

Hi, if I comment the line, the default border is not painted :)

Hello Proman,

I did a small modification to your program you it gets set on SAM_SetFocus
and gets removed on SAM_KillFocus... this could be used to identify where
you are in a form. I hope you don't mind.

Regards,

Conrado

nice idea, but the strange re-painting problem didn't disappeared :(

you can see the behaviour:
the datafield is created with the correct borders:

the form is resized:

the form is enlarged but the datafield border is corrupt:

Thanks Pronan Rodi

Like Krzysztof Dorko say Christian Astor, posts a sample code for make a
color border and too have the same problem, if the border is take back from
another object then don't paint the border again ...

i test an just lost the internal border ( see the attach ), then i thin that
the ploblen maybe are in the order that the object repaint ...
in my case when anoter whindow is over the test window just lost the
internal border..

Try something like that

Code: Select all

frmTest
     On WM_SIZE
              Call SalInvalidateWindow( dfSpecial )
