Hi,
I've posted various questions before to the forums/mailing list but
never had much of a response, there's only one guy who kindly answered
many of the posts, although I am still in some confusion.
Is there an irc to ask stuff? Sometimes you need a simple one on one to
get your head around how something works.
Well, here goes anyway... The question:
I'm manipulating the Laszlo dashboard demo and editing the contactslib
class. It seems the class is passed a dataset, and it loops through it
to render some tabs.
I don't really see how the class knows to loop over the dataset, other
languages have simple loops, I can't see any in the class at all.
The problem I've having is trying to get an image to display on the tab.
The text elements use a datapath to reference a value of the current
data in the dataset like so:
[code]<text name="tabName" fontsize="10" fgcolor="0x222222" x="150"
y="2" datapath="name/text()" font="vera" width="180" />[/code]
How can I change this to show an image instead? I'm doing something like
this but it doesn't work:
[code]<view name="tabImage1" x="9" y="2" datapath="image1/text()"
width="30" height="30">
<method event="oninit">
var imgSrc = this.datapath.xpathQuery();
tabImage1.setSource(imgSrc);
</method>
</view>[/code]
Is there an easy way to simple set the resource of a view to use a url
defined in the dataset, much as the text works. It seems logical to me
you should be able to do resource=image1/text()", or maybe
datapath="image1/text()", but niether of these works. I had to do a
kinda bodge on some other code to get at the url by using xpathQuery,
but doesn't seem to work so well here.
Is there a guide to how this all works? I've read much of the
documentation but it doesn't go into much detail regarding looping
datasets. I haven't found any definitive this-is-how-it-works with
step-by-step examples which would really help explain things much better.
