[!RebGUI] A lightweight alternative to VID
older newer | first last |
Pekr 22-Jun-2005 [1674x2] | ... so my question is rather simple - can it ever be done, using plain Win32 API? |
IIRC Carl also planned to improve granularity of event system, introduce view plug-ins, but I don't know ... | |
shadwolf 22-Jun-2005 [1676] | hum directX this means bye bye portability .. |
Graham 22-Jun-2005 [1677] | I think that you need to look at where Rebol/View is going to be used, and decide how best to improve those areas where the market opportunity is greatest. Is smooth animation that opportunity? |
Carl 22-Jun-2005 [1678] | These are things to be added... but by a team of people. Should move this discussion out of this group. |
Volker 22-Jun-2005 [1679] | switching group? but graphcs is important to rebgui! :) |
Graham 22-Jun-2005 [1680x2] | Most of us just want a decent cross platform development toolkit. |
that is complete in it's widget set. | |
Volker 22-Jun-2005 [1682] | dx can be wrapped and made cross-plattform. |
Graham 22-Jun-2005 [1683] | Even though the embedded market is important, the desktop market is much more important .. IMHO |
Carl 22-Jun-2005 [1684] | I agree with that statement. |
shadwolf 22-Jun-2005 [1685x4] | I found the proper SVG output format for InkScape it's SVG Plain text (this format is lighter than the normal SVG output fomat |
here is the fraisier.svg version ;) | |
http://shadwolf.free.fr/fraisier-plaintext.svg | |
we save 4ko and the format seems to be more close of the one of Sodipodi (witch have been used to draw the iconset gived by Ashley in svg-demo.zip) | |
shadwolf 23-Jun-2005 [1689x3] | I'm playing with ashley's svg-demo.r script code in order to understand it and know what are missing in it. I took as reference the blender.svg file because it's tiny and half rendered. I constate that <g></g> block that encap transformations and transformed things is not support and LinearGradient is not supported too ... |
How can I handle in DRAW/AGG the transform matrice ability ? | |
better changing to AGG groupe sorry | |
Normand 27-Jun-2005 [1692] | do %rebgui.r display "RebGuiTest" compose/deep/only [ label "Query" t: text 40 "" return a: area 100x50 "In the beginning, " button "Insert" [ insert a/text "Title{}" ; edit-text a enter insert tail a/text "And from a barely documented VID, a need for something bare but easy to document: RebGui. And the user saw it was good." ; edit-text a enter show a ] do [at face/pane/3/text 10 insert tail face/pane/3/text "there was View 1.3. "] ] ; End Display do-events How to move the cursor to inside the brackets of Title{->Here<-}. How to enter a newline, and more generally use the function defined in rebgui-edit.r into the area? ** Script Error: edit-text has no value ** Where: action ** Near: edit-text a enter More generally, how to enter a string and move the cursor after the insertion of it. Thanks for an answer to this 'II am New' question pertaining to RebGui. |
Ashley 27-Jun-2005 [1693] | This should get you going: display "Test" [ a: area 100x50 "Title {}" do [ rebfocus a system/view/caret: back system/view/caret show a ] ] The RebGUI edit-text function (and indeed the majority of the edit context) is designed to be used from within RebGUI widgets ... it's not "user-space" functionality. Manipulating text and / or focus is done via the standard view mechanisms (system/view/caret, focal-face, highlight-start & highlight-end) ... RebGUI just provides an encapsulated front-end to these. Depending on what sort of operations need to be performed (e.g. move the cursor to the Nth character), we can certainly add additional user-space functions (much like rebfocus), we just need to define what these functions are and how common their use would be. |
shadwolf 30-Jun-2005 [1694x3] | I have done the set of svg icons you ask me using inskscape plain text svg (the lighter svg format ...) you can get it here http://shadwolf.free.fr/RebGUI-svg-icons.zip .It's not author marking and it's my own work so no problems with rights issue. |
I hope you will found them reliable ... | |
now we have to focus on the widget SVG that can renderise them ;) | |
Ashley 30-Jun-2005 [1697] | Looks good under Opera. Has the SVG renderer you and Vincent have been working on got to the stage where it can display these? If so, post a link and I'll integrate that in. The entry point will be a function named 'load-svg in a separate file so we don't have to worry about "widget clutter", and I've already added a new 'icon widget and updated toolbar widget which use the 'load-svg function ... so we should be ready to go. |
shadwolf 30-Jun-2005 [1698x2] | actually not because we have several problems on recursion group interpretation on gradient effect (fill and for border line fill) so now we are trying to make a better engine that can be use more efficient ly rebol object! properties we are basing our work on xml-to-object function ... |
SVG format is so blury that you can't match it to a predeterminate struture you have to do a structure analyst for each leaf of the the object tree then get the needed information from leaf and nodes then convert them to rebol then apply the draw | |
Pekr 30-Jun-2005 [1700] | uh, is that because of flexibility of the SVG format, or because of XML deriver beurocracy? |
shadwolf 30-Jun-2005 [1701x2] | I think that's because technologie issue (graphics libs that would be used to normally render SVG files to screen are different from AGG ) then you have plenty of possibilities SVG can be seen as a VID widget tree where youonly get relevent informations but the structure have some recusing consept |
for example the path tag that describes a shape (AGG/draw word) have obligatory a d field but then to handle the rendering options you have lot of ways to handle it | |
Pekr 30-Jun-2005 [1703] | so maybe AGG is not originally designed to work with SVG? OK, we can integrated Cairo library then too :-) |
shadwolf 30-Jun-2005 [1704x3] | you can see the use of a style field in the path tag that encap all the graphical need (internal color / gradient effect, border size color /gradient etc...) or this information can be exploded in as many field that you have description |
Pekr I don't think so if you see the AGG library web site you will see lot of example of you to use AGG with SVG ... But there we are working in C++ and not in REBOL ... | |
so you have an XML struture we transforme it to a REBOL Object! tree then this tree must be glanced and translated to have the AGG draw block ;) | |
Pekr 30-Jun-2005 [1707] | so what you are trying to say is, that AGG itself allows easier SVG rendering, but our Rebol wrapper is not so flexible? |
shadwolf 30-Jun-2005 [1708x3] | hum I don't know if we can be so drammatical and have a so drastic point of vue .... |
It's a hard job to handle SVG structure and make our decoder able to decode all needed information that's all ;) | |
and in AGG we have differencies in the liearGradient definition that what we have in SVG | |
Pekr 30-Jun-2005 [1711] | ah, so the main problem here is imo still the same - XML parser. Building kind of "DOM". Rebol's XML parser is rather simplified after all. I do remember using Gavain Mckenzie's xml parser, which was much more usefull - it allowed for hooks during parsing and created rebol object too ... |
shadwolf 30-Jun-2005 [1712x2] | for lineargradient SVG gives us a transform information (can be matrix, rotation,scale , skew, etc...) then we have an offset x1 X2 y1 y2 then we have color informations spread method |
fill-pen informations is different | |
Henrik 30-Jun-2005 [1714] | a bit off topic: iTunes has a widget for rating of songs with stars one to five. Basically it's a widget that has 5 different states, depending on where you click on it. Would that be on the todo list for RebGUI? I'm planning to have such a thing in my next rewrite of my listview, I showed you some time ago. |
shadwolf 30-Jun-2005 [1715x3] | I don't think it's planned ... |
but nothing prohibes you to make a sutch widget for rebgui ;) | |
actually my main problem i how to build path to reach information into the SVG rebolien converted object tree | |
Graham 7-Jul-2005 [1718] | This topic has been quiet for a while now .. anything happening?? |
shadwolf 7-Jul-2005 [1719x3] | yess I'm hardly developping SVG renderer widget as flexible and complete support of the SVG file format |
for the momment I have some problem to sum local and global matrix and to translate gradient effect | |
as cyphre connect once per week it's not easy for me to advance | |
Normand 9-Jul-2005 [1722] | Is there a tool to enumerate all the path to the text fields in a RebGui application. Rebol is great to draw interfaces, but boy is it owerwhelming to find the path of those fields. I did not find the way (if there is one) with Anamonitor003. To have an idea of what I talk see my never finished pet at www.biblex.org. |
