[Dynapi-Dev] Button/DynImage

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

I'm having major problems trying to get the Button widget to work with
DynImage.  I tried adding a setSize call when the images are loaded to
fix the problem.  But now in Netscape the images in the buttons
disappear onload.  Also, it causes NS to crash after you reload
sometimes.  Any help would be appreciated.

There was one problem that I think I fixed, is when you say new
Image(w||0,h||0). If you initialize the image to width or height to 0
in IE, then the when its finished loading it will stay 0, so I used an
if statement to fix that so that you don't have to specify the size.

I am working on a simple auto resize for DynImage.  It was overly complex the way it was.  It's almost done as I type this email.

[Dynapi-Dev] Adding/Removing Event Layers

[Raymond S. <dst...@or...>]

Bit stumped by this one.  Trying to emulate dragevent
(attachable/unattachable behavior) within a Widget without having to write
the eventhandler as a separate ext.  I've tried alot of different reference
scenarios to remove a created dynevent events handler nested in a DynLayer
attached to a parent layer.  How can I unattach and reattach this
dynamically?

Thanks

I have looked at how the images work. I have made somthing similair but I
find more simple. I created a TImage which in its constructor creates a
"real" image (as in an IMG tag) then I can play with it using function I
have created. Resizing would simply mean call ImgName.width and changing it.

The main issue with DynImage is getting the images width and height
when it is done loading.  Then the dynimage has to update itself and
invoke some kind of event saying its ready.  So ideally, you don't
need to specify the w/h if you want to use the actual width/height.
Because in the Button widget, it has to be able to resize itself, but
it can't do so until it knows the image's width and height, unless you
specify it.

I beleive in IE if you say x = new Image(w||0,h||0), it will
initialize the w/h to 0 even after the load (if w or h is 0), so thats
one of the problems with the DynImage as it is now.

Already done and working.  I've actually got quite a large amount of fixes/changes coming due to a lot of problems with widgets using the new inline creation system.  Currently there's only 1 very perplexing problem when using Button in another widget (pushpanel/scrollpane in particular) that is holding it back.  I will be sure it's all working in IE4 before releasing anything to CVS.

Did anyone figure out exactly what to do to get IE4/5 to stop selecting text for Label?

Re: [Dynapi-Dev] Adding/Removing Event Layers

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

You need a reference to the eventlistener object and then you call
removeEventListener(listenerobj);

One way is something like:

MyWidget.listener = new EventListener()
MyWidget.oncreate = function(e) {
   var o = e.getSource(); ....
}
MyWidget.prototype.dosomething = function() {
   if (...) this.addEventListener(MyWidget.listener);
   else this.removeEventListener(MyWiget.Listener();
}
