Where's the Window()

[Martin Rinehart]

I've got most of the components of a robust color chooser but I'm
having trouble pulling them together.

What I want is to have a ready-to-use but not visible pop-up object
created when the application is loaded. On a click on a color button,
this thing should pop up as a modal dialog. It should hide when the
user chooses OK, Cancel or clicks the window closing button.

"window.open(.. .)" opens a window, which is not what I want when the
application loads. My development platform, Opera on Konqueror,
doesn't support "new Window(...)". This was dead simple in Java (and I
may still be thinking in Java).

There's a Java example of where I'm going at

http://www.MartinRinehart.com/examples/color-chooser.html

(This is a slug in Firefox on XP Pro - use any other browser or FF
with XP Home or any earlier Windows. I've no clue why.)

The JavaScript version will be better.

What is your question?
How to open a new window when somebody pushes the button?

To do that you'll need window.open() not new Window().

You'll probably want the content in a div rather than a separate
window. You can hide the div and position/show it when needed. Browsers
generally don't have the idea of "modal" windows in any case, so you'll
need to go this route.

The color chooser in its own window is quite nice as you can drag it
around (inevitable: it pops up over something you want to look at). Do
I need to write a draggable div widget?

That insists on opening the window. I'd like to construct the window
before it's visible, then show/hide it based on the users' clicks.

Re: Where's the Window()

It just gets odder and odder.

function popup() { // called on button click
var cc = window.open( ... ) // window pops up
alert( cc ); // alert appears after window is closed. reports
"object Window"
alert( cc ); // reports "object Object"
}

Any reason for that?
Anyway, if you must: follow Daniels advise and make it a div.
And yes, you must take care of the dragging of that div-'window' then.

I doubt that...
I never saw that happening before.

What does the ... in your window.open(... ) actually hold?
If it holds a normal URL, windowname, etc this shouldn't happen.

alert( cc ); // reports "object Object"

Why would 2 subsequent alerts showing the same object give diffent
results if you didn't touch anything in between?

}

My guess is you are making a mistake somewhere, or not showing us the
whole story.

No, you just didn't see it until you closed the window. It was there
all along.

    alert( cc ); // reports "object Object"

So what? It is a host object. If it wants to report a different type
for closed windows, that is its prerogative.

And yes, you will need some basic mouse position reporting code.
Don't use a canned "drag and drop library" as they are mostly refuse.

yes. unhide a massive 'glass screen' at z-index 1, and overlay with our
popup div at z-index 2.

Nothing works till you remove the screen :-)

And just look at the difference!

In your dreams. :(

You're right. Opera launches new window in new tab, tricking me.

� � alert( cc ); // reports "object Object"

for closed windows, that is its prerogative.

I don't care what it reports. Problem is, it morphs from Window to
Object between two consecutive alerts. I don't like sneeky vars that
change type when they think I'm not looking.

The following crap is not finished code, it's try stuff and see what
happens code.

Now I've got it. New window is opened on tab two, on which Opera also
shows content of tab one pre-window opening. Alert pops on tab one,
but I'm looking at tab two. Closing the window on tab two also closes
tab two and returns to tab one, which is paused because the alert is
modal. OK the alert and execution resumes, which is the second alert.
Since there is no more window, the var is now just an Object.

Now, you guys cheerfully inform me, all that remains to do to get my
Color Chooser working is to write a little windowing OS in JS. No
wonder I couldn't find a decent color chooser already written.

Personally I think decent color choosers are written inline, in a div
that can be hidden/shown. Popups are often blocked.
