[Dynapi-Widgetdev] Bubble-Help Widget

[Volker R. <Vol...@bi...>]

Hi there,

started to develop my first widget. it is kind of a bubblehelp that
works like the alt-tag in images. with the mouseover a description is
shown. There is still some work to be done to make it a widget (maybe
some day). Are there any people interested in it? i would then keep on
working it to get a usable tool.

you find a demo at
www.web-dizain.de/bubblehelp/

Just move your cursor over the links and see....

P.S.: i was trying to do an implementation of the maybe known overlib.js
into dynapi2...

[Dynapi-Widgetdev] NN6 onmouseout delay More info,more questions

[David C. <dle...@ya...>]

Greetings,
 regarding the delay of the onmouseout in buttonimage
(does not fire till the second mouseover):
I traced the problem back to the code where it changes
the .src of the image.  The image for the button is
set with a setHTML call and is named.  The program
code then uses the name to change the source (.src).
If the code is given a setTimeout and then the images
are swapped in the initial setup, it works normally. 
It seems to be hanging when the following code is
executed the first time:

ButtonImage.prototype.change = function(img) {
	if (img) this.doc.images[this.id+"Image"].src =
img.src;
	
};

Is this a problem with the setHTML method, the
dynimage code or a problem with the images array in
NN6?
Anybody have any ideas?

Cheers,
Dave C. "You Changed What?!?"

I've changed my approach.  Instead of trying to extend CoreButton and
CoreToolBar, i copied the code and changed it.  This seem to be going
better.

Don't waste your time looking at this.

Thanks anyways.

[Dynapi-Widgetdev] Pulldown menu widget (1st attempt failed)

[Ken O. <ko...@an...>]

Hello,

Attached is my first attempt at creating a pulldown menu widget.  Any help
would be greatly appreciated.

My approach was to build the pulldown menus as a series of toolbars and
buttons.  I attempted to extend CoreToolBar and CoreButton.  The code
currently simply creates the buttons and tools bars.  Event handling stuff
is not present.

Anyway, addChild is complaining about something.  I'm doing something wrong
(hopefully not too stupid) and I'm now i'm starting to step through reams of
dynlayer code and I bet it's something an expert can answer quickly.

I also ran into a null reference problem.  On line 155 of dynlayer.js of the
01-25 release, child.css was null. Could be a symptom, but in any event I
changed it (without an understanding of what's going on) to the following to
get to the next problem.

if (child.z!=null && child.css!=null) child.css.zIndex=child.z;

BTW, is anybody else developing a pulldown menu widget?

Regards,

Ken

Re[2]: [Dynapi-Widgetdev] NN6 onmouseout delay?

[Robert R. <rra...@ya...>]

I find the examples a great tool.  Too often than not, there are bugs
that are posted with widgets and it is very difficult to debug dynapi
bugs in complex widgets.  The examples demonstrate the core
functionality.  I tested the events using the example included w/ the
dynapi except I added nested layers.  Tests like these are more
valuable when you are trying to test bugs in the dynlayer events.  If
you can prove whether a bug is a dynlayer bug or not, then you can
save yourself a lot of time that you can waste debugging widgets.

[David C. <dle...@ya...>]

Hey Robert,
 I stripped the page down to just the bare code
creating the buttonimage and got the same results.  I
also checked the mouse events example and it was
normal.

code:

<script language="Javascript"
src="../src/dynapi.js"></script>
<script language="Javascript">

DynAPI.setLibraryPath('../src/lib/')

DynAPI.include('dynapi.api.*');
DynAPI.include('dynapi.gui.dynimage');
DynAPI.include('dynapi.gui.buttonimage');

DynAPI.onLoad=function() {

	p1uimg = DynImage.getImage('butovu.gif',100,35);
	p1oimg = DynImage.getImage('butovh.gif');
	p1dimg = DynImage.getImage('butovs.gif');
	p1rimg = DynImage.getImage('butovh2.gif');

	buti01 = new ButtonImage(); 
	buti01.moveTo(40,100);
	DynAPI.document.addChild(buti01);
       
  DynImage.onLoaderDone=function() {
  	buti01.setImages(p1uimg,p1oimg,p1dimg,p1rimg);	
 }
}; 

</script>

see this here:
http://www.merlinsworld.net/dynapi_ri_dcexamples/image_button2.html

I will look for problems in buttonimage.js tomorrow.
If you see something wrong in how I am creating the
button, let me know please?

I noticed the same with your example in Mozilla, but it seems to be a
glitch somewhere in your code.  Using the examples included with the
dynapi, the onmouseout event seems to be firing correctly.

  Has anyone noticed a "glitch" in NN6 and DynAPI
where the onmouseout does not fire till the second
time you pass over the object?  I was looking at
compatibility problems with my image menu and started
checking out the individual sections.  I tested the
normal buttonimage and found this happenning.  Maybe
it is in my code, but it seems to be repeatable in
other examples as well.  After passing over the object
a second time (second onmouseover) the onmouseout

[Dynapi-Widgetdev] Collapse Menu

[Lujan I. F. <lu...@sa...>]

I tried the address provided by David Cushman at
http://www.merlinsworld.net/dynapi_ri_dcexamples/button_menu.html and it
worked OK in Netscape 4.7 and IE 5.5, but it worked extremely slow using
Netscape 6.0 and it didn't work at all using IE 6.0 beta.  The images
(buttons) didn't display at using IE 6.0.  Maybe we shouldn't be concerned
with IE 6.0 since it is a beta product, but it wouldn't be acceptable using
Netscape 6.0 since it is soooo very slow.  I don't think it's my processor
since I'm using a 550 processor.  The only other thing I noticed (both IE
5.5 and NN 4.7) is that the menu off the first "Button 2" seemed a little
bit sluggish where it would take several seconds to go to another button
after you left that drop down.

Thanks
Frank

Hey Frank,
  Not sure how the original worked, but I posted a
widget that does wipe and slide of the first main
menu, using an image button as the trigger.  Take a
look and if it does not do what you want, tell me what
things it does not do and I will see if I can do a
mod.
Example:

David,

> I found the API, well, akward, at least for my purposes.

I've been doing some thinking on what the interface could be.  What are your
thoughts on something like:

menuName.addMenuItem( id, type, menuItem, [data], [parent id], [before id],
[group] )

id = a unique identifier
type = "menu", "command", "seperator", "blank"
menuItem = another object with visual info or just a string (in which case a
menuItem is generated)
[data] = some data to store that is passed pack when menu selected (i.e. the
URL)
[parent id] = the ID of the parent if it is not on the root
[before id] = the ID of the item for this choice to be insert before.  If
empty, add to the end
[group]= a way of grouping commands - (can be used to diable commands in
groups)

menuItem Class:
		.caption = text to display (with & notation for key
accelerators (e.g
&File)
		.defaultButtonImage (optional - image for whole cell)
		.rolloverButtonImage (optional - image for whole cell)
		.mouseButtonDownImage (optional - image for whole cell)
		.selectedButtonImage (optional - image for whole cell)
		.disabledButtonImange (optionl - image when cell disable)
		.defaultClass (optional - for CSS link and text cells)
		.selectedClass (optional - CSS class when selected)
		.disabledClass (optional - CSS class when disabled)
		.buttonDownClass (optional - CSS class when pressed)
		.rolloverClass(optional - CSS class when mouse on)
		.iconSmallImage (optional - small icon to be displayed to
left of
caption - just like Windows)
		.iconLarge (optional - a bigger icon for ?)
		.text (optional string for tool tips or status bar text)
		.<positioning info> (optional - to allow for funky menus)

A user would create a menu object (opposed to number of buttons) and then
add menus and choices.  For example (to use some familar menu structures):

	myMenu = New NavigationWidget(size & positioning stuff for menu)
	myMenu.addMenuItem("file", "menu", "&File");  // Create a file menu
	myMenu.addMenuItem("filesave", "command", "Save", "FileSave.htm",
"file");
// Add choice to menu
	myMenu.addMenuItem("edit", "menu", "&Edit"); // Create edit menu
	myMenu.addMenuItem("editcopy", "command", "&Copy", "EditCopy.htm",
"edit");
	myMenu.addMenuItem("view", "menu", "&View"); // Create view menu
	myMenu.addMenuItem("next", "menu", "&Next", "view");  // Create sub
menu
	myMenu.addMenuItem("nextmessage", "command", "&Message", "next",
"ViewNextMessage.htm");  // Add a choice to sub menu

The widget should fire an event and pass the "id" and "data" (URL) when a
choice is selected.

To do something fancier:

	myCell = New menuItem("some text", myImage1, myimage2, positions,
etc);
	myMenu.AddMenuItem("id", "menu", myCell)


I haven't begun to consider implementation (although I've done similar
things in other languages).  At the moment, I'm only looking at it from an
interface point of view.  If we nail a good interface, other developers
might adopt it.  It would be great if one had a choice of many different
menu systems and it was trivial to switch between them.

What are your thoughts?


Regards,

Ken

Reply-To: dyn...@li...

Hey Ken,
  Some good stuff there.  Let me start out by
explaining the goal of the original widget.  I wanted
to be able to use the wipe.js to make the popup.js
appear when triggered by an image button (based on
buttonimage.js).  I wanted to use the popup.js as is
for compatibility purposes (have made changes now as
noted below).  Second, I wanted to have several
instances on the page that would not interfere with
each other.
Changes to popup.js:
  Altered the create listener to make it precreate
  added line to precreate listener to remove itself
NN6 has a real problem with execution speed when too
many listeners are active
  added lines to mouse item events to ignore submenu
items and blank items.

To address your comments (just why they are what they
are, not that they cannot be changed)
"Also, it seems unreasonable to to provide information
like menu depth and number of submenus when it has all
the info necessary to to figure that stuff out."
number of submenus:
  The structure is that it names the main menu (the
one with the effect) "menu" nad each submenu
"MenuSub[]" as part of an array.  This uniform naming
allows the resizing and assigning of submenus to be
done with just a number.  I could have assigned the
submenus as they were initialized also.  That may be a
good change.
  The menu depth is left over code, not removed yet. 
The widget now calculates the total display width of
the menu system for the "trapping" layer.
Other items in the initial setup
  "items below main" I am working on having the widget
calculate this

I am having problems understanding what the goals of
your code are.  However I have just started looking at
it and will probably understand better after going
over it a few times.  If you have time, could you
write out what it is supposed to do?  Maybe the
fasttreenode.js or treenode.js is closer to what you
are trying to do?  They are available at Richard's
site under Richard's examples.
http://www.resass.f2s.com/dynapi/php/index2.php

For everyone else, we are discussing my image button
menu widget.  Viewable here:

Subject: [Dynapi-Widgetdev] NN6 and too many event listeners
Reply-To: dyn...@li...

Greetings,
  First I know that we are not compatible with NN6
yet, but I still test my pages and widgets under NN6.
NN6 has a tendancy to slow down to a crawl with
complicated DynAPI examples.  One thing I have noticed
and tested is that the more active event listeners on
the page, the slower (or not at all) it goes.  On my
menu widget, I started adding code in that removes the
event listeners when they are not needed.  The
precreate listeners include a line at the end to
remove themeselves and the menu item listeners are
also removed and added when active.
Question 1 Has anyone else noticed this or has a
better understanding of what is happenning?
Question 2 Does removing and adding event listeners
increase the browsers footprint in memory each time
the add is executed?
Question 3 Can anyone suggest a good utility to
monitor the browsers footprint in memory?

Cheers,
Dave C.  "You Changed What?!?"

It would be strange if eventlisteners slow things down.. you would need alot
of eventlisteners.
Note that even though we call them listeners, there not listening all the
time.. they are more handlers (and no, we're not renaming them)

Everytime an  invokeEvent('eventname')  is done, the invokeevent function
will walk thru the array of eventlisteners (just a simple array of objects)
and see if the corresponding event is attached to it.. if it is, it will
call that method of that eventlistener object.

It doesn't make sense that it slows down so noticeable, do you have a url we
can check to see it?

q2.  It might, not sure if normal javascript objects also increase the
footprint (or just dynamically generated html objects).
q3.  Taskinfo seems to be a complete tool for memory/cpu timing:

my cell is just a layer that adds the border effect to make it look more
windozish.  it only effects the base menu canvas.  it does not effect the
indiividual menu items.

[Ken O. <ko...@an...>]

Hi Dave,

Thanks for the pointer to the tree widgets.  I hadn't had a look at those
yet. (I only discovered DYN API last Wednesday - and I've been hooked ever
since.)

Anyway, that interface is more or less what I was trying to achieve.  It's
doing things in a slightly different way.  (I think in a better way - but
I'm not sure yet.)  So essentially my code example was simply defining a
hierarchical menu structure in a similar way to the various tree examples.

Some of my goals are:

* To be able to build multi-level pull down menus (like Windows applications
or the microsoft web site)
* Have a standardized (and extendable) interface for a variety of
hierarchical selection objects such as pulldown menus, tree selectors,
outlook sytle menus, bottom based menus, anything imaginable
* Higher level tools (akin to Razor) could use this common interface afford
a lot of flexability for skins.  For example, one skin chould have pulldown
menus.  Another skin could have a slide in tree.  Another skin could have
lamp posts.
* As way of quickly wacking out these applications and easily maintaining
them something like the XML and XSLT example I posted could be used.

Another thought that occurred to me, is that things may be nicely rounded
out if popup.js used buttonimage.js as its individual choices.  Michael
Pemberton had a post very similar to this recently that changed popup.js to
use a cell.js.  A pulldown menu can be a toolbar that aggregates buttons
that spawn popups that aggregates buttons that spawn popups and so on.

As a general question, is there any good reason that more widgets aren't
part of the 01-25 release?  One of the more difficult tasks I'm having
ramping up is knowning what widgets are there, what works with what etc.
Also, pulling in multiple widgets from multiple people is starting to be
confusing.  I very much appreciate Richard's ongoing directory standard
structure efforts.  Are the widgets going to be part of the release in the
future (and in CVS)?

RE: [Dynapi-Widgetdev] NN6 and too many event listeners

[Pascal B. <pa...@dy...>]

It would be strange if eventlisteners slow things down.. you would need alot
of eventlisteners.
Note that even though we call them listeners, there not listening all the
time.. they are more handlers (and no, we're not renaming them)

Everytime an  invokeEvent('eventname')  is done, the invokeevent function
will walk thru the array of eventlisteners (just a simple array of objects)
and see if the corresponding event is attached to it.. if it is, it will
call that method of that eventlistener object.

It doesn't make sense that it slows down so noticeable, do you have a url we
can check to see it?

q2.  It might, not sure if normal javascript objects also increase the
footprint (or just dynamically generated html objects).
q3.  Taskinfo seems to be a complete tool for memory/cpu timing:

[Dynapi-Widgetdev] NN6 and too many event listeners

[David C. <dle...@ya...>]

Greetings,
  First I know that we are not compatible with NN6
yet, but I still test my pages and widgets under NN6.
NN6 has a tendancy to slow down to a crawl with
complicated DynAPI examples.  One thing I have noticed
and tested is that the more active event listeners on
the page, the slower (or not at all) it goes.  On my
menu widget, I started adding code in that removes the
event listeners when they are not needed.  The
precreate listeners include a line at the end to
remove themeselves and the menu item listeners are
also removed and added when active.
Question 1 Has anyone else noticed this or has a
better understanding of what is happenning?
Question 2 Does removing and adding event listeners
increase the browsers footprint in memory each time
the add is executed?
Question 3 Can anyone suggest a good utility to
monitor the browsers footprint in memory?

Cheers,
Dave C.  "You Changed What?!?"

Re: [Dynapi-Widgetdev] RE: RE: [Dynapi-Help] Widget test Image button menu

[David C. <dle...@ya...>]

Hey Ken,
  Some good stuff there.  Let me start out by
explaining the goal of the original widget.  I wanted
to be able to use the wipe.js to make the popup.js
appear when triggered by an image button (based on
buttonimage.js).  I wanted to use the popup.js as is
for compatibility purposes (have made changes now as
noted below).  Second, I wanted to have several
instances on the page that would not interfere with
each other.
Changes to popup.js:
  Altered the create listener to make it precreate
  added line to precreate listener to remove itself
NN6 has a real problem with execution speed when too
many listeners are active
  added lines to mouse item events to ignore submenu
items and blank items.

To address your comments (just why they are what they
are, not that they cannot be changed)
"Also, it seems unreasonable to to provide information
like menu depth and number of submenus when it has all
the info necessary to to figure that stuff out."
number of submenus:
  The structure is that it names the main menu (the
one with the effect) "menu" nad each submenu
"MenuSub[]" as part of an array.  This uniform naming
allows the resizing and assigning of submenus to be
done with just a number.  I could have assigned the
submenus as they were initialized also.  That may be a
good change.
  The menu depth is left over code, not removed yet. 
The widget now calculates the total display width of
the menu system for the "trapping" layer.
Other items in the initial setup
  "items below main" I am working on having the widget
calculate this

I am having problems understanding what the goals of
your code are.  However I have just started looking at
it and will probably understand better after going
over it a few times.  If you have time, could you
write out what it is supposed to do?  Maybe the
fasttreenode.js or treenode.js is closer to what you
are trying to do?  They are available at Richard's
site under Richard's examples.
http://www.resass.f2s.com/dynapi/php/index2.php

For everyone else, we are discussing my image button
menu widget.  Viewable here:

[Dynapi-Widgetdev] RE: RE: [Dynapi-Help] Widget test Image button menu

[Ken O. <ko...@an...>]

David,

> I found the API, well, akward, at least for my purposes.

I've been doing some thinking on what the interface could be.  What are your
thoughts on something like:

menuName.addMenuItem( id, type, menuItem, [data], [parent id], [before id],
[group] )

id = a unique identifier
type = "menu", "command", "seperator", "blank"
menuItem = another object with visual info or just a string (in which case a
menuItem is generated)
[data] = some data to store that is passed pack when menu selected (i.e. the
URL)
[parent id] = the ID of the parent if it is not on the root
[before id] = the ID of the item for this choice to be insert before.  If
empty, add to the end
[group]= a way of grouping commands - (can be used to diable commands in
groups)

menuItem Class:
		.caption = text to display (with & notation for key accelerators (e.g
&File)
		.defaultButtonImage (optional - image for whole cell)
		.rolloverButtonImage (optional - image for whole cell)
		.mouseButtonDownImage (optional - image for whole cell)
		.selectedButtonImage (optional - image for whole cell)
		.disabledButtonImange (optionl - image when cell disable)
		.defaultClass (optional - for CSS link and text cells)
		.selectedClass (optional - CSS class when selected)
		.disabledClass (optional - CSS class when disabled)
		.buttonDownClass (optional - CSS class when pressed)
		.rolloverClass(optional - CSS class when mouse on)
		.iconSmallImage (optional - small icon to be displayed to left of
caption - just like Windows)
		.iconLarge (optional - a bigger icon for ?)
		.text (optional string for tool tips or status bar text)
		.<positioning info> (optional - to allow for funky menus)

A user would create a menu object (opposed to number of buttons) and then
add menus and choices.  For example (to use some familar menu structures):

	myMenu = New NavigationWidget(size & positioning stuff for menu)
	myMenu.addMenuItem("file", "menu", "&File");  // Create a file menu
	myMenu.addMenuItem("filesave", "command", "Save", "FileSave.htm", "file");
// Add choice to menu
	myMenu.addMenuItem("edit", "menu", "&Edit"); // Create edit menu
	myMenu.addMenuItem("editcopy", "command", "&Copy", "EditCopy.htm", "edit");
	myMenu.addMenuItem("view", "menu", "&View"); // Create view menu
	myMenu.addMenuItem("next", "menu", "&Next", "view");  // Create sub menu
	myMenu.addMenuItem("nextmessage", "command", "&Message", "next",
"ViewNextMessage.htm");  // Add a choice to sub menu

The widget should fire an event and pass the "id" and "data" (URL) when a
choice is selected.

To do something fancier:

	myCell = New menuItem("some text", myImage1, myimage2, positions, etc);
	myMenu.AddMenuItem("id", "menu", myCell)


I haven't begun to consider implementation (although I've done similar
things in other languages).  At the moment, I'm only looking at it from an
interface point of view.  If we nail a good interface, other developers
might adopt it.  It would be great if one had a choice of many different
menu systems and it was trivial to switch between them.

What are your thoughts?


Regards,

Ken

Re: [Dynapi-Widgetdev] Collapse Menu

[David C. <dle...@ya...>]

Hey Frank,
  Not sure how the original worked, but I posted a
widget that does wipe and slide of the first main
menu, using an image button as the trigger.  Take a
look and if it does not do what you want, tell me what
things it does not do and I will see if I can do a
mod.
Example:
