I have posted a small bit of code in the demos newsgroup for a small
addition to EWB that allows you to set a date using scrolling wheels
like a smartphone. Feel free to use or add to and enhance.

Is there something else we need to do you run this Date Scroller?

Compiler doesn't like YearScroller.Canvas.Canvas  Referenced variable, parameter or function Canvas does not exist.


initDateScroller(YearScroller.Canvas.Canvas, MonthScroller.Canvas.Canvas, DayScroller.Canvas.Canvas, HourScroller.Canvas.Canvas,MinuteScroller.Canvas.Canvas,Year,Month,Day,Hour,Minute);


Is there a change to TPaint that needs to be done?

Maybe html5 support needs to be activated for the project?

Sorry , forgot to mention that I had to edit the WebCtrls file in the
framework source to make the "Canvas" field under the TCanvas class a
public field.

Any chance of doing this to the original source Tim, as I have to do
this to use the date scroller and the signature capture that I wrote.

No, the controls/components in EWB do not expose the underlying DOM
elements, as a general rule.  This leads to some really bad coding issues
when direct modifications aren't reflected in the wrappers, or vice-versa.

I think I have to modify the Display option each update too.

It would be good to enable some option where you have
InternalCanvas and InternalDisplay properties that perhaps always return nil,
unless you have called a function that accepts we take responsibility. If we send
you code that has that enabled, turn us away. But by having a nil return we can
actually code for it, and test where the problem is.

Just a thought.

I'm sorry, but this won't be changing.  If you want direct access to the
element, you can get it (DOM tree), but I'm not going to make it easy to do
directly because it is way too easy to just drop down and start modifying
the element attributes without realizing how it affects the behavior of the
framework.  The end result is more of my time figuring out and then
explaining why something is broken in the framework.  I break enough of the
framework on my own, and I wrote the damn thing. Smile

Okay, I have taken Tim's advice and modified the code so I pass in the
date scroller as a TPaint object and extract the canvas in the external
javascript file using

PassedInPaintObject.tpaint_fcanvas.tcanvas_fcanvas;

This means that I do not need to modify the existing framework.

Thanks Tim.

Just found a problem with this code, it doesn't work when the
compression is turned on.
