World: r3wp

... which is still the latest official release ( http://www.dobeash.com/download.html
)


118 was the commencement of a makeover but as Graham says broke a 
lot of things. The 118 efforts morphed into an almost total rewrite 
of 'the engine' (everything bar the widgets) and were about 90% complete 
(build 218) when R3 gobs hit the scene (a game changer IMHO).

I found out that the space on the right results from a margin command 
later in the script. I used tight on the top before the menu widget. 
If i didn't reset the margin, menu  fills up to the right. If i want 
to reset the right margin to 4 px later to indent the following widgets 
to the left, it resets the margin for the complete window to 4 px. 
That means for  the menu as well. Now i have a workaound  an use 
a 4 px box to keep the distance from the right border. As Rebgui 
will not be developed any further, it seems that i have to live with 
it. I have chosen build 218 because of the better design, compared 
to the previous ones (My opinion) But thanks for the hints.

What is this build 218? Typo? I thought 118 is the latest.

No typo or not mine. It is a development build from Ashley and Graham, 
not GA.  Ashley mentioned it (90% finished rewrite) in his previous 
post.

scratch that question - I don't know how I had pulled down a version 
118 before

The current edit-list shows the matches where you are typing which 
is a little distracting.  How about the drop list appearing with 
the matches  instead?

What I'd like to emulate is this http://rxterms.nlm.nih.gov:8080/

since the drop list uses a modal popup window I guess it would require 
a lot of modification :(

In 117, you can't seem to tab into a table eg.
 

 display "" [ field field table options ["column" left 1.] data [ 
 "ab" "cd" ]] do-events


but you can in the svn version .. what change has to be made to allow 
this?

set-focus is different ...

ok, include table into the tabbed block and use the set-focus from 
the svn works so far

Hi, 


Am just moving over here from TCL-land and would like to try RebGUI. 
However, there seems to be two versions: one downloadable from the 
Dobeash site (rel #117) and on resident in SVN (#218).


Which is the one with which to go; and if the version on SVN, what 
is the method to down load an use?

Any assistance would be appreciated.

Rick

Don't use 118 .. the only one working is 117

The SVN version is incomplete and was a rewrite which was not finished

thanks, again.

And of course, VID is still valid as well.

VID is the native REBOL GUI dialect. If you're just getting started, 
and doing basic UIs, it's worth a look.

I've posted my lookup-field as per my video here 

http://rebol.wik.is/RebGUI/Lookup-field


It uses a lot of code from the edit-list which I don't quite grok! 
 So, there's a bug which requires you to initialize the field with 
a backspace first.

So, I can feed this widget 18,000 entries which I don't think you 
can with the edit-list.

Hello everybody, I have a problem with Linux:  DRAW   choose a font 
that give problem displaying:

example: ['text "Hello word!"]
view layout [ box 100x100 effect [draw example ]]

on linux it gives a blank window.
I added:

example: ['text "Hello word!"]
if (pick system/version 4) = 4 [
	fnt1: make face/font [ 
		name: "/usr/share/fonts/truetype/freefont/FreeSans.ttf"
		size: 12
		]
	os: "linux"
	]
if os = "linux" [ insert example reduce ['font fnt1]	]
view layout [ box 100x100 effect [draw example ]]

This solution is good, but using REBGUI  it doesn't work anymore.
What can I do?

Actually, this group is inappropriate, you should use View, or Linux

(I suppose that you are mistaking VID and RebGUI)

aha, sorry, I did not find out you actually used RebGUI, sorry

Max, fonts should work the same between View, VID and RebGUI. Please 
provide a small snippet of RebGUI code that demonstrates the problem.

Ok

do %rebgui.r
example: ['text "Hello word!"]
display "Example" [
	aaa_stats: box 50x50 effect [  draw example ]
	]
do-events

It doesn't display anything.

Do you know a solution?

On windows you get a nearly invisible "hello world"

but your problem is linux isn't it?

example: [pen black text "Hello word!"]
display "Example" [
	aaa_stats: box 50x50 effect [  draw example ]
	]
do-events

No, he solved the problem with Linux by providing an absolute filepath 
to the font.

The problem is trying to use VID's LAYOUT (and maybe also VID's VIEW) 
after initialising RebGUI.

If I remember correctly, RebGUI unsets 'LAYOUT, or redefines it for 
its own use. So it won't work anymore as you expect with VID.

Exactly, any suggestion?

Well, it's not going to be easy to mix them. Ashley made the decision 
early in RebGUI development to specifically unset (the majority of?) 
the built-in VID functions. I think primarily to reclaim memory use, 
but maybe also to avoid mixing code. (I didn't really like this decision, 
myself.)

You could probably modify the RebGUI sources so it doesn't do that, 
or ~maybe~ redefine the VID functions yourself (I think more challenging). 
Every time there is a RebGUI update, you'd have to remodify the RebGUI 
sources, so I wouldn't be inclined to do that myself. It depends 
how badly you want them to coexist.

You can use VID styles with the 'style word:

rebol []
do %rg
example: "Hello world!"
display "Example" [
    style 20x20 data [
        box blue example
    ] 
]
do-events

rebol []
do %rebgui.r
example: [pen black text "Hello word!"]
display "Example" [
    style 20x20 data [
        box blue effect [draw example]
    ] 
]
do-events

RebGUI (b117 and later) does *not* redefine layout. It does however 
redefine alert, confirm and many of the request-* functions.

The fact that starting a fresh console session and entering:


 view layout [box black 100x100 effect [draw [pen white text "Hello"]]]


no longer works on the linux and Mac ports of REBOL is I believe 
a REBOL/VIew bug (despite a workaround that may work for VID but 
not RebGUI).

It's a bug in that the font directories are unknown in linux

so it should work in rebgui as well as the draw dialect is unchanged 
in rebgui

Oops, sorry Ashley, I was wrong about RebGUI unsetting LAYOUT. (It's 
been a long time since I tried RebGUI.)

MaxV, tell us the rebol version you are using (system/version) and 
the RebGUI version.
Show us the full code which does not work with RebGUI.

I noticed your second example (using RebGUI) did not include the 
code which sets the font path.
Just to be sure, can you confirm you tried it together?

nickA didn't provided a font information in his draw block plus he 
didn't gived a different color... plus R2 VID sux with fonts and 
specially under linux.

I tried Nick code, but I obtain 
** Script Error: style has no value

All my code is:
Rebol []
do %rebgui.r
fnt1: make face/font [ 
		name: "/usr/share/fonts/truetype/freefont/FreeSans.ttf"
		size: 12
		]
example: ['text "Hello word!"]
insert example ( reduce ['font fnt1 ])
display "Example" [
	aaa_stats: box 50x50 effect [  draw example ]
	]
do-events

REBOL/View 2.7.7.4.3 5-Jan-2010


Linux ubuntu 2.6.32-21-generic #32-Ubuntu SMP Fri Apr 16 08:10:02 
UTC 2010 i686 GNU/Linux

I haven't tried loading fonts in draw on Linux, but the rest of this 
works (the color is changed by the draw command "pen red"):

Rebol []
do %rebgui.r
font1: make face/font [
    ; name: "/usr/share/fonts/truetype/freefont/FreeSans.ttf"
    size: 11
    style: [italic bold]
]
example: compose [
    font (font1)
    pen red
    text "Hello World!"
]
display "Example" [
    style 20x20 data [
        box snow 100x100 effect [
            draw example
        ] 
    ]
]
do-events

** Script Error: style has no value
** Where: layout
** Near: style 20x20 data [
    box snow 100x100 effect [
        draw example
    ]
]

MaxV,  this works perfectly for me on Ubuntu 10.04.1, using your 
rebol.deb installer - I ran Ubuntu directly from the CD created using 
the most recent Ubuntu download, installed REBOL using your Ubuntu 
package, and ran this script.  Perhaps your version of RebGUI is 
different than mine?  This version loads rebgui.r from an http:// 
link:

rebol []
do http://re-bol.com/rebgui.r
font1: make face/font [
    name: "/usr/share/fonts/truetype/freefont/FreeSans.ttf"
    size: 11
    style: [italic bold]
]
example: compose [
    font (font1)
    pen red
    text "Hello World!"
]
display "Example" [
    style 20x20 data [
        box snow 100x100 effect [
            draw example
        ] 
    ]
]
do-events
quit

YES! It's the Rebgui version that is different.
