[!RebGUI] A lightweight alternative to VID

That's just broad strokes, but it should give you an idea. You could 
even generate this kind of thing with the prebol preprocessor.

Ashley, the very first web site I visited .. cnn.com, has these menus 
down the left hand side coloured in blue, with the active one in 
red.

If you click on the red one ie. the active one, it still refreshes 
the page for you.

Given it's a one-line change, I'll include it in the next build bar 
any strong objections.

Ashley i prefer to wait until next release because if I strat to 
use divergent version this will not be cool

Active tab refreshing: with regards to user experience, I'm with 
Ashley, but with regards to simpler implementation that gives the 
user (the developer using the widget or the end-user) a choice how 
to deal with the event, I'm with Graham. Either way, I don't think 
people are going to lose too much sleep over this one. If I was using 
tab-panels, I would probably try to catch redundant refreshes, if 
my refreshes were slow, whether the current implementation catches 
them for me or not, in order to be safe with possibly future implementations. 
:)
Ashley, colors/widget used by tab-panel:  I still think it is an 
inherent problem of tab-panel, but it is better I pursue one of the 
other ways you suggested, which probably needs doing anyway. It's 
easier for me to change the slider than for you to change the tab-panel 
colour, which affects more widgets.  (I admit I must be a flat colour 
man..)

ashley, can you add in slider style a function wich changes the size 
of the dragger ?
or can you say me how can change it easily
thank you

BTW, I just logged on to paypal.com website, and they have 5 tabs 
at the top.  Clicking on an active tab still refreshes the page. 
 I am sure that there are however just as many websites that do not 
refresh.
Here's an inconsistency.  If I have a button, and bring up an alert, 
the button remains highlited even after I move the mouse away.  But 
if the button does something else, it dehilites when I move the mouse 
away.
How does one create a widget in a hidden state?  I've got two tab-panels 
one over the other.  I want to hide the one underneath, and expose 
it when I hide the top one?

Use SHOW and HIDE
Graham
18-Jun-2005
[1564x2]
in Vid you could set the show? facet to false.
perhaps I need to display/layout, and then use hide ?
Ammon
18-Jun-2005
[1566]
That should do it...
Graham
18-Jun-2005
[1567]
nope.
Ammon
18-Jun-2005
[1568]
Hm...  Show and Hide are Natives I wonder what RebGUI is doing to 
stop them from working...
Graham
18-Jun-2005
[1569x2]
Got it.
Use a 

do [ widget/show?: false ] 

in the layout.
Is there a word similar to 'focus ?
Ashley
18-Jun-2005
[1571]
The following *should* work:

	display "Test" [text false]  or  [text #[false]]


But don't for some reason (the layout parser checks for it). I'll 
fix this for the next build.

display "" [ sum: field "10" button "clear" [ sum/text: copy "" show 
sum ]] do-events
after a couple of clears, the text in the field is no longer visible
Ashley

Luc: dragger size is controlled by ratio, so just do a "sld/ratio: 
a / b show sld" or similar in your code.
Graham: replace the "show sum" with "rebfocus sum"
Graham
18-Jun-2005
[1576]
Ok.  But if I leave the mouse over the button, it takes 2 clicks 
to clear the field
Ashley
18-Jun-2005
[1577]
Fixed in latest build.
Graham

Is the current build able to be encapped?
Ashley

Not with a pre-1.3 SDK. %rebgui-widgets.r uses some 1.3 specific 
words such as case, unless, etc. Once it starts making greater use 
of AGG-specific draw commands there will be no going back.
Graham

Pity, as a 1.3 SDK timeline has not been announced yet
Can't have more than one password field ?

>> display "" [ password 10 return password 10 ]  do-events
** Script Error: Face object reused (in more than one pane): none
** Where: view
** Near: show scr-face
if new [do-events]

I think the default behaviour for a tab within an edit-list should 
be to leave the list, and not insert a tab.
How does one force rebol to recover memory?

If the memory is allocated (in local variables) then you can't. Cos 
it is still in use.
Otherwise, try recycle/torture


But first, try to work out what stats is saying (cos I don't understand 
it) --- look at this:
  stats

  longstring: form now/precise loop 20 [append longstring random longstring]
  stats

Longstring is some 25meg long and not very compressible , but the 
2nd stats returns (for me) a slighly larger number than the 1st time.


Stats has some refinements now -- try help stats -- they might be 
more useful for tracking memory.

And maybe switch to core group for a general discussion.

i guess you had a lot of garbage already? this is from a fresh console.
Ashley

Graham: If you want to reduce RebGUI's memory footprint just rename 
%dictionary/American.dat ... that alone accounts for more than half 
the memory footprint. ;)

Interestingly enough, adding:

	button "Clear" [clear system/locale/dict]

or

	button "Clear" [system/locale/dict: none]


to %tour.r have lesser and differing effects (from a stats / recycle 
perspective).

Gabriele -- no I was working from a fresh console.

Suggests the new GC is a bit odd, or platform dependant in some ways.

Ashley, please note the bug with two or more password fields.
shadwolf
19-Jun-2005
[1591]
graham the bug with many password fields is undertable that's because 
it's designed in a field + password field window (like login requestor 
....)
Graham
19-Jun-2005
[1592]
As long as it can be fixed.  I have a screen I want the user to enter 
the password twice :)

hehe sure you are rght cONFIRMA TION password  for config panel  
!!! I think Ashley doesn't think on this case ;)

I have actually got three password fields .. one for registered users 
to login, and two for new users to register :)
Ashley, you might want to change this page http://www.dobeash.com/it/rebgui/
and remove the reference to it working with the sdk ( until RT releases 
a 1.3 compatible SDK ).
Ashley
20-Jun-2005
[1597]
Page updated with, "...  You can even use it from the REBOL/SDK (when 
the View 1.3 SDK is released) ...".
Graham
20-Jun-2005

:)
Once it's done, perhaps RT can bundle it in with the sdk.

I'm currently developing a load-svg-icon function that will take 
an SVG file name and size, and return a scaled draw block. Some questions 
need addressing first though (feel free to post the GPL answers to 
the licensing group):


1) Can I distribute a set of GPL SVG icons with the RebGUI zip bundle? 
If so, under what terms / conditions?

2) If someone creates a RebGUI binary application (with the to be 
released SDK) can they include GPLed SVG files, and if so, under 
what terms / conditions?

3) Can GPLed SVG files be distributed under a different file name(s)? 
(e.g. rename gnome-gtk-folder-icon3.svg to open.svg)

4) What if I want to take a set of GPLed SVG files and distribute 
them as pre-converted draw-blocks (so RebGUI apps don't need to convert 
icons from SVG to Draw)?

Now some design questions:


1) Should the result of the proposed load-svg-icon be a draw block 
or an image?

2) Should RebGUI have a stock image cache or a stock draw-cmds cache? 
(i.e. is it better to cache draw cmds or images)
