Chromeless Xul Window Draggable???

[ivanicus]

Hello people!!!

I have a xulrunner application that goes to a predefined width+height
on startup and has no chrome:

[code]
<window
        id = "mainwindow"
        title = "My Window Title"
        hidechrome = "true"
        width = "800"
        height = "600"
        xmlns  = "http://www.mozilla.org/keymaster/gatekeeper/
there.is.only.xul"
        xmlns:html = "http://www.w3.org/1999/xhtml">
        <script src="xulbrowser.js"/>
        <browser flex="1" id="browser" src="" type="content-primary" />
</window>
[/code]

My questions:

1) Is it possible to make that whole window draggable without adding
the system chrome??? I could another element inside that window above
the <browser> element and tell it to be draggable... But I have no
idea if that's even possible at all, needless to say, how to
accomplish it...

2) In such scenario, could I send some kind of event to the XUL
window, in order to minimize it/maximize it??? The event would be sent
from the application running inside the <browser> element...

Thanks in advance!!!!

If you cover <browser> by anything, then it will not get mouse events.

I think solution will be:
1) if you want to drag window, then JS should call some me method in
<window>.
2) This method first create <canvas>, render current browser state into
canvas, and place canvas over <browser>. Of course canvas should handle
mouse events, and move window according to mouse move.
3) when you detect drag is done, just hide/destroy canvas.

But it is a bit ugly. While dragging, app will look like frozen. To
avoid this, you may frequently (30 fps?) render browser into canvas.

But i think best solution it will be add some XUL, and just hide it when
it is not needed. Code will show drag grips only when drag is requested.

I've never used it, but the <titlebar> element looks relevant.

@Arivald:

Actually, when I meant above, I meant on top, but not covering it...
as a titlebar or smth like that

@neil:

<titlebar> DOES the trick!!! THANKS!!!!!!
