[!REBOL3 GUI]

with prior gui, I could see 'draw-results, or something like that 
in the structure. Was it removed? What was it good for? :-)

I am not sure, but I think it's result from translating draw dialect 
to draw commands, this will be simplified later.

Pekr: 'btw - I am not sure "hint" is a good name?' - actually, yes, 
since the INIT-HINT is a hint (look up the word in the dictionary), 
how the algorithm should determine the INIT-SIZE value
(for a panel)
The 'AUTO hint just tells the algorithm to calculate the panel INIT-SIZE 
"automatically" (= using an algorithm) taking into account the panel 
contents. This means, that you, as a user, do not have to specify 
the panel INIT-SIZE, which might seem less comfortable to you.
Of course, if you know, what is the INIT-SIZE you want to have, you 
can specify it as well using a different hint.
'Yes, they are two identical gobs' - funny, that is a nice contradiction
In fact, you cannot have 'two identical gobs', you can have only 
one

R3 still hard crashes with the GUI :-( unreproducible ....
I have a question towards the aproach to design a form. Following 
code does not work for me (result-wise):

view [hpanel 2 [label "Name:" field button "ok"]]


Simply put - button is on a new row, but it probably causes field 
to align to the right? Or more precisely - button extends the column 
cell, and so the field is pushed to the right in an undesirable (albeit 
expected) manner. Should I put buttons supporing the form out from 
the panel containing fields?
Rebolek

you use panel style, so you've got 2x2 grid. "ok" button is simply 
on 1x2 position and 2x2 position is empty. If you don't want grid, 
use group style.
Pekr

[6558]
I don't like the group style :-)
Rebolek
7-Mar-2011
[6559]
why is that?
Henrik
7-Mar-2011
[6560]
the group style is not for forms
Pekr
7-Mar-2011
[6561]
I am just not sure. What I am still confused about is the different 
semantics of particular styles. I wonder, if there could be just 
panel-like semantics, so I could use:

hframe 2 []
hpanel 2 []
hgroup 2 [] ; with no need for return keyword


But that would be limiting to the group style, as it has no cells 
- each row is separate IIRC ....
Rebolek

[6562]
That's why there's different semantics.
Pekr

But my above example is some food for thoughts. When I think of forms, 
I know that form might be enclosed in some pane (being it group or 
panel or frame I don't care - just visually separated from the background). 
Then it usually contains pairs of labels and fields. Btw - in R2 
it was easy to right-align label - is that possible with R3 GUI? 
And I think that some buttons belong to the form - e.g. Edit, Submit, 
Cancel, and some might belong to the Window.
So the question is, how do I get button visually together with labels 
and fields, not influencing my design? Put buttons into subgroup 
or subpanel?
Henrik
7-Mar-2011
[6565]
yes, buttons should be in a subpanel
Pekr

[6566x2]
Does not work for me:


 view [hpanel 2 [label "name: " field hpanel 3 [button button button]]]
The nice thing is, that I do know, what it does not work, and I do 
know that the behaviour is correct, it is just - undesirable ... 
:-)
Rebolek

[6568]
Yes, there's support for alignment. I'm not how much of it is currently 
accessible, but you should be able to align cells in panel.
Pekr
7-Mar-2011
[6569]
hgroup for buttons does not work either, because that group is part 
of the first cell of the second row ...
Henrik
7-Mar-2011
[6570]
you want the button panel outside the other panel.
Rebolek
7-Mar-2011
[6571]
Pekr, it works exactly like it should.
Henrik
7-Mar-2011
[6572]
(don't be distracted by the visual frame. this will change, so you 
will have better control of what is visually framed)
Pekr
7-Mar-2011
[6573]
That is what I asked - if I should put buttons outside the first 
panel? But philosophically - that does not work
Rebolek
7-Mar-2011
[6574]
Maybe not philosophically, but technically it's perfectly working.
Pekr

[6575x3]
Rebolek - don't drag me in that discussion - I said, that I know, 
that it works like it should. But I also said, that the result is 
undesirable for me ....
Henrik - what is planned then in that regard? New frame style, and 
new panel style?
I have to look into some forms in some other apps, how they do solve 
visually buttons belonging to form ...
Henrik
7-Mar-2011
[6578x3]
GROUP and PANEL would by default not create a frame. Derivative FRAME 
styles would create a frame.
how they do solve visually buttons belonging to form

 - when this works correctly, you will be able to do any visual combination.
Rebolek, something that bugs me though is spanning multiple cells. 
Is this possible?
Rebolek
7-Mar-2011
[6581]
in PANEL style?
Henrik
7-Mar-2011
[6582x2]
yes
or will there be a different solution of inheriting cell-sizes across 
multiple panels? this is for forms where label width is necessary 
to be identical for multiple form parts, such as 4 column forms or 
forms separated vertically by full-width spanning parts.
Pekr

[6584]
Henrik - so you want to be able to merge cells? Hmm, not sure it 
would not be difficult for Ladislav to count into the engine? :-)
Henrik
7-Mar-2011
[6585]
I don't know how difficult it is to do, but it seems like a necessity 
to me in such cases.
Pekr
7-Mar-2011
[6586]
But generally yes, for forms, I expect easily setting up pairs of 
right alighned labels, and fields. That has to be ultra easy, along 
with the ability to set some margin, but that should be workable 
via the stylize.


Henrik - I think that if you add frameless alternatives, then it 
is not a big deal ... I just have problem with current aproach, where 
subpanels create too many lines in the GUI :-)
Henrik
7-Mar-2011
[6587]
Pekr, ok. Just ignore the lines and spacing between panels for now. 
The arrangement is not going to change.
Pekr
7-Mar-2011
[6588]
Is the change planned for the next release?
Rebolek
7-Mar-2011
[6589]
Yes.

Could you please write it down in a form understandable to mere humans?
I would especially like to know what do you want.
Something like "does not work for me" may be understandable to some 
supernatural beings with mind-reading capabilities, but, being a 
mere human, I am lost.
How about this, would you prefer such a result?

view [hgroup [label "name: " field return button button button]]
Pekr

[6594]
yes, this is what I would expect, if I would don't know about panel 
implementation internals (cells)
Henrik
7-Mar-2011
[6595]
you wouldn't be able to align labels and fields correctly below eachother, 
as far as I can see
Pekr
7-Mar-2011
[6596]
you mean without cells?
