Re: Google Webmasters: A proposal for making AJAX crawlable

[ThomasWrobel]

I'm not sure what to make of this, seeing as I was half way into
making my site work without javascript for
web crawlers.

Re: Image/Absolute panel...how to make the clickhandlers fire on the abs, ignoreing the image?

[ThomasWrobel]

Ok, for anyone still looking at this thread, I found the solution.
Its quite simple;

 Image.addMouseDownHandler(new MouseDownHandler(){
public void onMouseDown(MouseDownEvent event) {
event.preventDefault();
}
 });

This will stop Firefox trying to drag the image itself, thus letting
the application act like googlemaps, and scroll correctly on its own.

Thanks everyone :)

Re: Image/Absolute panel...how to make the clickhandlers fire on the abs, ignoreing the image?

[ThomasWrobel]

oh, and I made a more simple sample file here;

http://www.lostagain.nl/Panelstreamer%20Demo/panelstreamer.html#File=psftest/Layers.psc&X=432&Y=375

This just has 1 layer, and 2 objects on it...making it a bit easier to
test in firebug.
Note if you delete the element "helper", you will then get stuck on
the other image object. So it seems any image object is draggable by
firefox.

Re: Image/Absolute panel...how to make the clickhandlers fire on the abs, ignoreing the image?

[ThomasWrobel]

Yes, the sample might be a bit too complex to pin down.

Currently the one online consists of;

1xAbsolute panel tied to the ID ("InfiniteCanvas") on the html page.
This absolute panel I have made extend FocusPanel and implemented to
have MouseListener and MouseWheelListener and gave it the code to
handel the dragging.
This absolute panel also can contain multiple other absolute panels (1
for each layer of the file)
Each of those panels contain various contents, but normal image files
with pngs loaded. (other possibilities include frames of text,html or
canvas objects).

So thats DraggableAbsolutePanel <<  Absolute Panel (s) << Image
widgets.

The background of space is just set as a texture on the first layers
element (background-image:url(images/BACKGROUND.jpg);).

The square in the middle is just the center of the html's table, which
contains the draggable abs panel. The rest of the widgets in the
tables over cell's are just text, buttons, and a custom dropdown box.
None overlay the center, so I suspect the surrounding elements arnt
effecting it.

The event handlers as specified above are just on the center draggable
absolute panel, I havnt specified anything else myself.
I'm using onMouse Up/Leave/Enter/Down and MouseWheel.

My overall goal is just to have a google-mappish interface to a
collection of abstractly arranged (and sized) widgets. Those widgets
and layers being arranged by a standard format XML-like file. In this
example I'm showing it of as a type of comic. The specific idea is
described in Scott McClouds Reinventing Comics, although I think it
will be useful beyond just comics.
The interface currently seems to work nicely in Opera and even
(tolerably) well in IE.  Chrome doesn't seem to load anything at the
moment, but I think thats a separate issue.

I suspect what Thomas Broyer suggested might still be the problem, as
looking in FF when the image is dragged (rather then the background),
you can actually see the image being dragged completely outside the
frame. Like you'd see from dragging any image in FF. This clearly isnt
from my code. I have set draggable to false (see above) but FF seems
to be ignoring this. (or it wasnt the right setting to use).

Thanks.

Re: Image/Absolute panel...how to make the clickhandlers fire on the abs, ignoreing the image?

[ThomasWrobel]

Scratch that, I tried using
"-moz-user-select:none;" and it stops being selected in Firefox (looks
neater), but it still gets stuck to the mouse

I just think that "mouse up" isnt being fired on the underlaying abs
panel when the user releases the mouse after a drag.

Re: Image/Absolute panel...how to make the clickhandlers fire on the abs, ignoreing the image?

[ThomasWrobel]

Good idea but no effect.
At least, I think its got no effect, still getting the stuck mouse
problem.

The code I added was;

contents.getElement().setAttribute("draggable", "false");
contents.getElement().getStyle().setProperty("webkitUserDrag",
"none");
contents.getElement().setPropertyBoolean("draggable", false);

(I tried "none" rather then false, but I think its supposed to be
false, I also tried just the last and just the first line)

Heres the result;
http://www.lostagain.nl//Panelstreamer%20Demo/panelstreamer.html#File=./psf/Layers.psc&X=4240&Y=2168
(try moving it about like you would googlemaps)

I think the problem is its being selected all the time. In Opera it
works fine, and I note nothing is selected.

Re: Image/Absolute panel...how to make the clickhandlers fire on the abs, ignoreing the image?

[ThomasWrobel]

reg "Basically is it possible for an image widget to be "transparent"
as
regards to click events, passing them to the panel under it?"

Sorry to bump this, but I haven't been able to find a solution myself
apart from very crude work-arounds.
It seems like something fundamental I should know how to do too...if
it exists.
So a confirmation/denial from someone would be nice :)

Re: Announcing GWT 2.0 Milestone 1

[ThomasWrobel]

Fantastic.
Lots of great stuff there.
Particularly look forward to being able to use Firebug in
hos...development mode.

ClientBundle's sound cool, and should help speed up some stuff.
Although what I most want is the ability to dynamicaly load a bundle.
(so, for example, a client can change the whole theme of the a at
runtime by loading a single file)

Also, are Listeners still being used then? Or is it all Handlers now?
Because some widget libs haven't caught up yet. (Sliderbar on the
Incubator, for instance).

Cheers,
Thomas Wrobel

Re: Fetching a page ver a 302 redirect?

Actualy, forget that.
It seems the redirection wasnt causing the error, but rather it was
coming from the wrong domain.
Annoying that it merely comes out with a null, making it hard to
diagnose, rather then a error.

Re: Google Wave Invite

[ThomasWrobel]

Its not about exclusivity, its simply the fact it isnt ready for the
public yet.
If they launched now, most of the public would be put off by bugs,
lack of functionality, lack of widgets, sever-load issues etc.

They need a limited number of people for both google, and developers
working on wave-related projects, to get feedback on what needs
to be fixed.

Re: Is it possible to have history with the normal GET url format

[ThomasWrobel]

I ran into this issue recently, its particularly annoying if you want
to have your site work javascript free (for search engine bots), as
well as allowing the user to just save links as they would normaly.
(or cutting and pasteing the url etc).

Frankly, there is no good solution.
Best I found you can do is have a button on your site that generates a
url which users can use to exchange with eachother. (like google maps
does).
Just taking the url with the # would work fine for users with
javascript, but not without.

What helps a little bit though, is you can use a little big of
javascript to automaticaly turn a  "?" into a "#". So you can
effectively have two versions of the site with nearly the same urls/
parameters, and those with javascript will see the  history token
method, and those without see the normal query.

The two mighty Ians helped me out on this thread here;

Re: Remote controlling an iframe

Id like to know this too.
I'm not sure if its even possible for the parent frame to know the url
of the child frame if it changes.
My experiments always resulted in getting the initial url it was set
too, and not the new one since the user clicked.

Re: How to react on every new typed in character of a textbox

[ThomasWrobel]

I'm a bit confused why you dont just search for the whole text from
the filterText every time a key is pressed.
Surely thats what your effectively doing anyway by getting the current
text and adding the new characters?

Because the problem at the moment, if I'm understanding correctly, is
simply the filterText isnt being erased/reset when you want it to be.

Remember you can also use onKeyUp to get the state after the key is
pressed and released.

Re: How to show history for text fields?

[ThomasWrobel]

I think it varies per-browser.
Using opera here, I get no such list on the search field on this
group.

However I -have- had it before with my own text fields made using GWT.
In fact, as I was using a suggestion box, this caused problems as I
was
getting both the browsers suggestions and my own. So its certainly not
that gwt fields cant do it, and I didnt do anything special to enable
it either.
Since the last version of GWT and Opera that problems gone...not sure
who's change fixed it. Maybe browsers no longer see gwt fields as
ordinary text fields somehow?

It would be usefull to know a global way of enabling/disableing such
browser-based lists, but I'm not sure a standard for that exists :-/

[/hopes other people give feedback]

Are you using the war structure? or the old one?
Have you tried deleteing the files before it compiles?

Your right...this does seem a problem with gwt on Firefox 3.5

A huge amount of duplicate loading going on, not just with that bundle
but also

Re: _________________How to fix the side-bar bug in this group.

[ThomasWrobel]

no problem, Id get annoyed too if I see someone posted
 just to get attention.
The problems been coming and going over the last few weeks.
Dosnt seem browser related, as that screen was from Chrome a few days
back.
The group is working ok for me now, again, although it had the glitch
this morning, hence the post.
Hopefully its gone for good, if not people can use my work-around.

I'm adding that to the benefit of those experiencing this problem;

It allows people to actually read the title, rather then having it cut

Re: DeckPanel with visible layers?

[ThomasWrobel]

Couldn't you do the progress bar, however you like, then just query
its (absolute) location after its on the page, putting a label at that
position?
(so effectively the widgets arnt tied together at all)

If you want the progress bar to resized verticaly to match the text
size you could then size it after the label is positioned.

A bit of a fudgy solution, but it would give you a progress bar with
text ontop surely?

Re: How to get URL in GWT?

[ThomasWrobel]

I dont think theres a simple way, youd need to get the whole URL, look
between the second / and the 3rd /, then split the string around the
" : "

IP = UrlString.split(":")[0];
Port = UrlString.split(":")[1];

Re: what are prerequisites for learning google window toolkit

[ThomasWrobel]

I got started with no javascript or java skills. Merely an
understanding of basic codeing (I previously knew Delphi, Basic,
Actionscript).
Moderate html/css skills.
Really gwt was easy enough for me to learn everything as I went,
especially when using Eclipse (which is a lovely IDE), and Firebug
(which helps no-end in tracking down problems).

Re: Hosted mode Caching problem

[ThomasWrobel]

Have you tried using a .htaccess file on the sever to force no-
cacheing?


Header set Cache-Control: "private, pre-check=0, post-check=0, max-
age=0"
Header set Expires: 0
Header set Pragma: no-cache


(If you save this to a  *.htaccess file this will set everything in
the directory not to be cached)
Assumeing your sever is apache.

Thanks, thats 1/3rd of the problem solved then ;)

Probably need to use a regex. grr. I always get muddled with them.

Absolutely.
GWT has been absolute bliss to work with.
Getting rapid results, acting predictably, and even managing to (95%)
make IE behave itself.
Ive used it to make so many different things each one giving more
resources to build from.

Re: Polygons using GWT

[ThomasWrobel]

You need to use the Canvas object for this;

Re: Image layering using GWT

[ThomasWrobel]

I use the same method. Absolute Panel allows overlapping images (or,
any widgets you like).

Is it possible, however, to do the opersite, have an image on another
where the top image dosnt capture the clicks?
(that is, its "transparent" to clicks, and the lower image or the
absolute panel itself will capture them) ?

Re: Catching Hyperlinks before they are executed

[ThomasWrobel]

I'm not sure thats possible at all. You might have to make gwt link
objects that look like normal hrefs and replace all of the ones in the
page with these.
I had to do this myself for my project. (but for a different reason, I
needed bookmark links to work in frames...IE had some bugs that meant
I needed to use gwt links instead).

Re: Image/Absolute panel...how to make the clickhandlers fire on the abs, ignoreing the image?

[ThomasWrobel]

Actualy, Ive just noticed this only effects Firefox...opera works
fine.

Is this a bug in Focus panel when using firefox? (the example online
is a focus panel containing a Absolute Panel, which, in turn, contains
other Absolute panels).

Re: Making a fancy GWT Chart

[ThomasWrobel]

I dont know much about sever-side rendering, but cant the sever render
the image to a url, possibly triggered by gwt calling a php function?

Also, have you looked into the possibility of GWTCanvas being used to
draw with gwt?
http://code.google.com/p/google-web-toolkit-incubator/wiki/GWTCanvas

It can handle gradients..but not in IE.
(if its just liner gradients on rectangles though, you could also just
do it yourself by drawing lots of lines changing the color each time).

Re: "semaphores" in gwt

[ThomasWrobel]

I think your options are;
a) Just nest one request inside the other.
or
b) Do both requests separately, but within both the OnResponse check a
flag to see if the other one has finished as well. If either flags
that both are done, then trigger the message/code you want to run
based on this.

I think b is better, but I'm sure someone else might have better more
detailed advice.

Re: File Manipulation / Processing in GWT

[ThomasWrobel]

Not sure how you mean.
You can use GWT to read a file, then mess about with it as a string,
then post the result to a PHP file that can write the file to your
sever.

Re: History Token

Guess a frame could be used to hide the token (so the whole site is in

Re: Create own widget

[ThomasWrobel]

Why not just use a horizontalpanel with two buttons next to eachother?

HorizontalPanel buttongroup = new HorizontalPanel();
buttongroup.add(buttonOne);
buttongroup.add(buttonTwo);

If you want to make this into its own class, youd do;

public class myButtonGroup extends HorizontalPanel {

Button buttonOne  = new Button("test 1");
Button buttonTwo  = new Button("test 2");

public myButtonGroup() {

this.add(buttonOne)
this.add(buttonTwo)

 }

}


Preferably in its own file.
Then you can use myButtonGroup whenever you want these two buttons.
eg.
myButtonGroup testgroup = new myButtonGroup()

Re: Spinner Widget in 3d

[ThomasWrobel]

Theres no inbuilt 3d rendering engine in javascript or gwt, so you'd
either have to find one and try to make it work with gwt, or you'd
have to code your own ver the canvas element. (which lets you draw
anything 2d, and thus with smart code you can make anything 3d).
Both probably very hard tasks.
Its certainly possible, however, as some of the chrome demos show;

Re: Load external html files inside a popup

surely thats just a method of styleing the html pages to look like

If you use an iFrame, gwt will treat the contained page exactly like a

Re: SuggestBox problem...any work-around to get the selection text when one is chosen?

[ThomasWrobel]

'SelectionHandler didnt seem to work at all.
I dont think we are supposed to be able to use that with suggestbox;

"Note that there is no method to retrieve the "currently selected
suggestion" in a SuggestBox, because there are points in time where
the currently selected suggestion is not defined. For example, if the
user types in some text that does not match any of the SuggestBox's
suggestions, then the SuggestBox will not have a currently selected
suggestion. It is more useful to know when a suggestion has been
chosen from the SuggestBox's list of suggestions. A SuggestBox fires
SuggestionEvents whenever a suggestion is chosen, and handlers for
these events can be added using the addValueChangeHandler
(ValueChangeHandler) method."
