Re: [flexcoders] Re: sizing dinamically the screen
Hey See the easiest thing is to replace the x and y with 100% values
say for eg now ur app width is 1024 enter
100%

Set your Application width and height to 100%. Then, when javaScript
resizes the Object and/or Embed tag (NOT the document), then the
Application will resize itself appropriately.
You may want to do some basic experimentation and/or research on
DHTML. That's beyond the scope of this forum.

You need to be resizing the object/embed tag, not telling Flex to
resize the Application object, so Flex doesn't need to be involved in
the process, unless you want to be able to click a button to initiate
the resize. But all that needs to do is just call a js function, which
should be able to handle it without any info from Flex.
RE: [flexcoders] Re: sizing dinamically the screen
Reduce the variables, establish functionality one step at a time,
testing to make sure it continues to work.
Step 1: Write javascript to resize what you want. Don't do anything
else until you can do this part.

You may want to do some basic experimentation and/or research on
DHTML. That's beyond the scope of this forum.
[flexcoders] Re: sizing dinamically the screen
Gustavo:
Sorry, but I don't think the approach you are taking is necessarily
advisable, or even technically correct (in one regard). Specifically:
1) screen.width (and screen.height, and screen.availableWidth, etc.)
allow JavaScript (DOM) code to discover the size of the user's monitor
(screen hardware), not of the browser window in which your Flex
application is running. (The available* properties then subtract from
that size any operating system 'reserved' screen real estate, such as
the Windows task bar.)
2) I would be very surprised if JavaScript code could alter the value
of any of these properties--by definition they could not be under the
control of a browser window, so they should be read-only. Therefore,
code like
screen.width = 1024;
should not be expected to work.
Even if that code _does_ happen to work with one Browser or Operating
System, I wouldn't rely on it!
3) A reasonably reliable way to ensure that your application is
running in a browser window of the size that you want, is to use the
JavaScript/browser DOM Window.open() method to open a new window,
which gives you the opportunity to specify the size of browser window
that you want your application to have. Be sure to note that you are
specifying the overall (e.g., outer) size of the window; you are NOT
specifying how much (client) area that your application will get. ***
Different brands (and versions) of browsers will use different amounts
of space for their own 'chrome' (UI elements such as the URL/address
bar, etc.). I don't know of any way other than cross-browser testing
to discover the exact values, and they may change when a new version
of a browser is released!
4) If you don't want to open a new browser window, then you can use
the Window.resizeTo() DOM call in order to modify the size of the
current window.
For both 3) and 4), security policy in modern browsers may affect: the
success of opening a new window (i.e., pop-up blockers), and to place
limits on net window size.
5) You can call the JavaScript/DOM code from your Flex application
using the Flash ExternalInterface API. For more information, see (for
example):
http://livedocs.adobe.com/flex/3/html/help.html?content=passingarguments_4.html
6) For more information about the Window.resizeTo() browser DOM API,
see (for example):
http://msdn.microsoft.com/en-us/library/ms536723(VS.85).aspx
7) My _recommendation_ is that you consider abandoning the notion of a
fixed-size application window. Flex containers support liquid layout
very nicely and it is not much (extra) work to let your application
work that way. In other words, if/when the user resizes their browser
window, have your application adjust its layout accordingly. If you do
that, I think that it is also reasonable to specify a (window) size
below which your application won't be able to re-size itself to (and,
thus, scroll bars may appear).
Good luck!

Gustavo:
Sorry, but I don't think you're coding this correctly. Specifically:
1) I don't see your browser size detection code in the HTML wrapper
file at all. E.g., it is missing:
script type=javascript
var browserHeight= screen.availHeight;
var browserWidth = screen.availWidth;
/script
2) In any case, I'm not 100% clear as to what you are trying to
accomplish via the external interface. However, to get the available
screen width the following code will *probably* work (I haven't tried
it or tested it):
In ActionScript (note the quotation marks):
var width:Number = ExternalInterface.call(getAvailWidth);
assuming you have a JS function (in the HTML wrapper file) like this:
function getAvailWidth()
{
return screen.availWidth;
}
Then write similar code for the height, etc.
3) BTW, as a general rule, I've found it most productive to debug JS
code first (in isolation), _before_ attempting to call it from Flex.
4) Please look at the Adobe documentation for the ExternalInterface
API and the HTMLWrapper file again. I think--for now--you've reached
the limit as to what can reasonably be addressed via postings on
FlexCoders.
Good luck,
Jim

P.d: the aplication for mac computer has a window.open() but
problem is the windows browsers, so instead of that
I've been trying to apporach the windows, not much of success right
now.

Sorry, but I don't think the approach you are taking is necessarily
advisable, or even technically correct (in one regard). Specifically:
1) screen.width (and screen.height, and screen.availableWidth, etc.)
allow JavaScript (DOM) code to discover the size of the user's
monitor
(screen hardware), not of the browser window in which your Flex
application is running. (The available* properties then subtract from
that size any operating system 'reserved' screen real estate, such as
the Windows task bar.)
2) I would be very surprised if JavaScript code could alter the value
of any of these properties--by definition they could not be under the
control of a browser window, so they should be read-only. Therefore,
code like
screen.width = 1024;
should not be expected to work.
Even if that code _does_ happen to work with one Browser or Operating
System, I wouldn't rely on it!
3) A reasonably reliable way to ensure that your application is
running in a browser window of the size that you want, is to use the
JavaScript/browser DOM Window.open() method to open a new window,
which gives you the opportunity to specify the size of browser window
that you want your application to have. Be sure to note that you are
specifying the overall (e.g., outer) size of the window; you are NOT
specifying how much (client) area that your application will get. ***
Different brands (and versions) of browsers will use different
amounts
of space for their own 'chrome' (UI elements such as the URL/address
bar, etc.). I don't know of any way other than cross-browser testing
to discover the exact values, and they may change when a new version
of a browser is released!
4) If you don't want to open a new browser window, then you can use
the Window.resizeTo() DOM call in order to modify the size of the
current window.
For both 3) and 4), security policy in modern browsers may affect:
the
success of opening a new window (i.e., pop-up blockers), and to place
limits on net window size.
5) You can call the JavaScript/DOM code from your Flex application
using the Flash ExternalInterface API. For more information, see (for
example):

You need to be resizing the object/embed tag, not telling Flex to
resize the Application object, so Flex doesn't need to be involved in
the process, unless you want to be able to click a button to initiate
the resize. But all that needs to do is just call a js function, which
should be able to handle it without any info from Flex.
