Re: [Re: [Dynapi-Dev] Label Cover Bug]

[Bill W. <bil...@us...>]

One of the reasons I saw was that there was no oncreate being captured by the
Label, only onresize.  In the Button object, (assuming text was passed to it),
the first thing is does is to call its own 'setText' method which eventually
makes it down to the dynlayer's setSize method, which invokes the resize
event, which is being captured by the label.  The onresize handler gets the
ContentWidth and ContentHeight which, since it has not been created yet, is
still at null.  This makes the coverlyr's width and height, 0 and 0.

What I did was to give the label an oncreate method:
	listener.oncreate = function(e) {
		o = e.getTarget()
		o.setText(text)
		o.pack()
		if(o.hasCover){
			o.coverlyr.setSize(o.w,o.h)
		}

	}

Likewise, I changed the Button object's setText method to (if it wasn't that
way to begin with, I'd have to look back):
Button.prototype.setText = function(text) {
	if (this.label==null) {
		this.label = this.addChild(new Label(arguments[0]))
		this.label.setSelectable(false)
	}
	else {
		this.label.setText(text)
		this.label.packWidth()
	}
}
Lastly, I added these lines to the first part of Button's recenter method:
		if (this.label.hasCover){
			this.label.coverlyr.setSize(this.w,this.h)
		}else{
			this.label.addCover(this.w, this.h)
		}

That way, the text is set and the label is added when the button is
instanciated, the label is added when the button is created, now its size is
known, and therefore, the label size can be set.
This is kludgy to me, and it was only to get the Button object to work right. 
But I think the answer may just lie in making a proper oncreate handler for
the label.

If you want, I can attach my modified label.js and button.js files.

I saw what you did with the Button, that is, it will take either text or an
image, and thought I would apply the idea to a slide out menu widget I'm
making.  Now, my widget will take a string, a Button, or a CoreGridButton
(which I also had to make work with the new core).

I love that CoreGridButton.  Domino has something similar.

Speaking of Domino, If there are any other domino developers out there, I have
managed to port DynAPI into a Domino database. pretty easy, but then it was
only DynAPI 1 which was a lot flatter than this version.
Now I can do things like having having dynamic forms, views, agents, etc. that
I can submit back to the server for processing, and get responses back.

however this can/should be accomplished with event handling.  As far as I can
tell setSelectable() works perfectly fine in Netscape.  It cancels the mouse
down event and stops selecting of the test.  There must be an equivalent IE
method to do the same.
