 Posted: Sun Mar 30, 2008 2:17 am Post subject: 0 terminated string of (*HJson.value).toString |
 |
|
here is a example:
| Code: | if( auto ele = rootElement.getId("textarea_id".dup) )
{ auto str = (*ele.value).toString;
Trace.formatln("string {}", str);
} |
I use this trick to remove the null everywhere:
| Code: | if(str.length && str[$-1] is '\0')
{
str.length = str.length -1;
} |

| Thanks. I will fix this in the next release. Also, you will no longer need to write (*ele.value).toString but ele.value.toString will be fine. By the way, why do you need .dup in here rootElement.getId("textarea_id".dup)? |

thx a lot!
I used a HWND to load two sourc.htm, I have not lucky to figured out some issues, e.g., click button a, but button b has been executed, so I tried add .dup to string, tried add sleep(seconds) before OnDomready .... to see the result.
subclass your HLayoutControl class for every HWND now, seems ok.

For buttons you can do something like this: | Code: | myButton.handleEvent(delegate(HBehaviorEvent e)
{
if(e.cmd==BUTTON_CLICK) {return true;//dome something}
else return false;
}); |

is it possible one delegate to handle all button events?
| Code: | buttons.handleEvent(delegate(HBehaviorEvent e)
{
if(e.cmd==BUTTON_CLICK)
{
if(p.element["link"])
//navigateTo(p.element["link"]);
return true;//dome something
}
else return false;
});
|
to handle hundreds of elements event (e.g. tree view, every li is a link) manually, it's nightmare.

Sure.
| Code: | bool myDelegate(HBehaviorEvent p)
{
//dosomething
}
HElement[100] myelements;
foreach(m;myelements) m.handleEvent(&myDelegate); |
Keep in mind that if you are using handleEvent you must keep a reference to the HElement somewhere, otherwise the GC could wipe out your event. If you are not keeping a reference you can use handleStatic instead of handleEvent. This way the handler will persist as long as underlaying HELEMENT is not destroyed by HTMLayout. |
