[svg-developers] dispatchEvent problem
Hi all,
we've been developing an application that displays complex SVG content
tot he user. We use ASV3.02 embedded in the IE6.
Such an SVG consists of many layers. Each layer may have plenty of
visible objects.
We had a requirement to implement so called Object look up.
The user clicks on SVG and we have to show all objects located at the
clicked point.
In the first approach we implemented it in the very nasty way.
We set pointer-events attribute for all objects to all.
We have a MouseClickListener added to the root of the SVG. Once the
user clicks we get the target and set the pointer-events to none.
Then we fire a Windows mouseclick again - the MouseClickListener
reacts on that. This time the target is different, since the last one
doesn't get a mouseclick anymore. In that way we go deeper and deeper.
At the very bottom of the SVG we have one big rectangle called
BACKGROUND. If our ObjectLookUp reaches this BACKGROUND we stop the
function and we display all found objects.
It works pretty fine until the user wants to switch to another
application during this click-loop. Because we send mouseclick, but it
won't be handled by our MouseClickListener, since svgViewer is not
visible anymore.
So would like to fix this problem.
We came to the idea to use dispatchEvent method.
So what we have is (pseudo code):
MouseClickListener{
handleEvent(evt){
if(evt.target == BACKGROUND){
showObjects(targetCollection);
exit();
}
targetCollection.add(evt.target);
evt.target.setAttribute(pointer-events, none)
// what to do here??
document.root.dispatchEvent(evt);
}
}
Since evt is already set and its target is set to the first object,
dispatchEvent will cause that handleEvent is called, but evt is not
updated - it is again the evt with target equal to the first object,
although the first opbject has pointer-events set to none.
We have no API for CreateEvent() in ASV3.0. What can we do?
It is hopeless.
Could someone help us?
I searched the whole archive for the answer but I couldn't find a
solution.
thank you in advance
cheers
Maciek

[svg-developers] how to know when ASV3 finishes rendering?
Hi all, I have to show quite a complicated SVG. Rendering may take even a few seconds. After the SVG is rendered I would like to perform additional action. But it MUST be after the rendering. Is there a way or trick how to retrieve this info from ASV3? Any suggestions are welcome cheers Maciek Yahoo! Groups Sponsor ~-- Fair play? Video games influencing politics.

[svg-developers] how to detect end of manual panning in ASV?
Is there any reasonable way to detect the end of panning (left mouse
button goes up while the cursor is a 'hand')?
I ve got some text I have to put into the SVG every time the position
of svg changes. But for performance reasons I don't want to call this
function while panning, but only once every time the user stops
panning (i.e. mouse button goes up and ASV was in panning mode, i.e.
you can see a 'hand' cursor) - then I would call my text-placing function.
I tested with mouse-up and it doesn't work at all. So finally I use
mouseHookEx API function but it makes some troubles in my app, so I
would like to avoid it.
From the other hand I wouldn't like to use my own panning
('mousedown', 'mousemove', 'mouseup' handling and changing translate
of the svg), since we have a strong requirement on how the cursor
should look like.
Using standard ASV panning I've got a warranty I have a 'hand'-cursor.
Is there any way to handle cursors in ASV3.02 (even on the system
level), then it could be an alternative to me to use this cursor
handling with my own panning.
cheers

[svg-developers] ready status
Folks, any idea how to be 100% sure ASV has finished processing of SVG? E.g. I set a transform attribute to the value rotate(45). It is a very big g element, so the processing takes a few seconds. Once I get back the control I understand ASV has finished, but I can see, that the processor is still busy for another amount of time and pressing Alt or Ctrl doesn't change the cursor to the standard one (e.g. a hand symbol when alt is pressed). Due to some reasons I really would like to know when the ASV hs finished its job. I use WebBrowser activeX to display SVG. I used readyStatus (it doesn't work properly while loading, so I event didn't try while manipulating of svg). I also tried some WebBrowser events but the event was raised before ASV has really finished. I assume from this bahaviour, ASV has its own thread for rendering. Is there any chance to get the point in time when it's really finished? regards Maciek - To unsubscribe send a message to: [EMAIL PROTECTED] -or- visit http://groups.yahoo.com/group/svg-developers and click edit my membership Yahoo!

[svg-developers] ASV3 bug??? ASV doesn't refresh very big svgs!!!
Guys, You are our hope. Have You ever tried to show a very big SVG using Adobe SVG Viewer? We have a chart which is 35m wide and heigh. And ASV has big problems with it. It shows the SVG correctly up to the 440th centimeter (a. 173rd inch). After that width and height the result are unpredictable. You can try if you want with easiest possible SVG: svg width=500cm height=500cm viewBox=0 0 500 500 rect x=0 y=0 width=500 height=500 style=stroke:red;stroke-width:0.5;fill:yellow/ /svg My question: Is it a bug in ASV (I guess so) or I'm doing sth wrong. I checked the datatype defined in the SVG standard, used to store width and height - it is SVGAnimatedLength, which consist of two SVGLength fields, and SVGLength stores values as floats (max 1.0*2^37 or 3.4*2^38). If you conver 5m even to twips you get 283464,5twips. It is still much much less then 2^37. We use ASV3.02 build 91, but I've tried also with ASV6 but it works same. regards Maciek - To unsubscribe send a message to: [EMAIL PROTECTED] -or- visit http://groups.yahoo.com/group/svg-developers and click edit my membership Yahoo!

[svg-developers] Re: ASV3 bug??? ASV doesn't refresh very big svgs!!!
You can beleive me or not, but we really need to show so big charts. My question was whether it is a bug (I don't see nay reason why it shouldn't work - our requirement is compliant to the SVG1.1 definition) or I'm doing sth wrong. Your solution works fine but the picture is relatively small. We have different chart scales and at the largest scale we show very big chart, and we cannot just squeeze it like You propose. Nonetheless thank You for Your answer. maciek --- In svg-developers@yahoogroups.com, Domenico Strazzullo [EMAIL PROTECTED] wrote: Hi Maciek, With what intent you made a 35x35 m chart? If it's for onscreen viewing and you don't set a viewbox then you need to scroll ~972 times across and ~1292 times down to see the end of the document, with a browser setting of 1024x768, and ASV does seem to have a problem there.

[svg-developers] real world unit vs screen resolution or display device
Hi all, PLS HELP!!! we've got a major problem with SVGs. It may have an absolutely distroying impact on our application. We use Adobe SVG Viewer 3.0 in the IE6.0. Our charts have fixed width and height given in real world units (like mm or px, - whatever) and they must be displayed exactly so on the screen - independent of the screen resolution or the display device parameters. Look at this. svg width=200mm height=200mm viewBox=0 0 200 200 rect x=50 y=50 width=100 height=100 style=fill:red/ /svg I expected the ASV to show me always!!! a rectangle which is 10cm wide and 10 cm high and which starts exactly 5cm (on x-axis and y-axis) from the (0,0) point of the SVG coordinate system. If I display it on my monitor in the 1280x1024 resolution it looks pretty well. But if I change the resolution to 800x600 I see my rect has nothing to do with the dimensions I expected :( It's been a BIG surprise to us for last few days. I went through the SVG1.1. spec but I can't really get how to make my rect look always same (independent of the resolution and display device). I hope it is just a matter of proper setting of width, height and viewBox attributes on the outer-most svg element. Any help is welcome. And we need it ASAP. cheers Maciek - To unsubscribe send a message to: [EMAIL PROTECTED] -or- visit http://groups.yahoo.com/group/svg-developers and click edit my membership Yahoo!

[svg-developers] different look in ie6 and vb6. Why?
Hi folks, I've got very simple SVG: svg width=400mm height=400mm viewBox=-100 -100 800 800 rect x=-100 y=-100 width=100 height=100 style=fill:red/ rect x=0 y=0 width=100 height=100 style=fill:blue/ rect x=100 y=100 width=100 height=100 style=fill:green/ rect x=200 y=200 width=100 height=100 style=fill:yellow/ rect x=-100 y=-100 width=800 height=800 style=fill:black;fill-opacity:0.5/ /svg If i let the ie6 display this SVG, I get a correct look of it. This SVG is really 400mm long and wide independent of the display device. But if I load this SVG in VB6 (using SVG ActiveX) my svg is centered in the activeX and its height is aligned to the height of the viewport. Any idea why? thanx in advance Maciek Yahoo!

[svg-developers] Re: different look in ie6 and vb6. Why?
Thanks Mario for Your suggestion. But then how such a small web server should like. How do you comunicate embedded SVG object from VB? Maybe You can give me a few hints, since I've got no clue how it should look like. Thank You Maciek --- In [EMAIL PROTECTED], Mario Vernari [EMAIL PROTECTED] wrote: Hi, I unsuggest to use SVG via ActiveX hosting in VB6. I have a long experience in this field and finally I switched to embed a small web server in the VB app, then show all the SVG content by a Internet Explorer ActiveX. Believe me: this way is the most sure and stable. Comparing the convenience between code complexity and debugging/stability/result, the web server choice is better. Cheers Mario Yahoo!
