Opening one applet window from another

Hi everyone,
Can anyone provide any pointers about how I can open one JApplet from another (say, on a button click). I am new to applet development and I searched for examples on this forum and google, but could not find anything relevant.
Thanks,
Alan

Hi Dear
Just use this simple commmand.
String url;
url1 = "http://<Name of the HTML page>"
try {
getAppletContext().showDocument(new URL(url1), "_blank");
} catch(Exception e) {e.printStackTrace();}
This will prompt another browser. In this browser write u r applet code & load the class file.
One thing more this will not work in the case if you are using appletviewer , it will only work when you running u r applet over the network.
In case you wana test with appletviewer then initiate the browser from the system .... In that case you have to search the net.

Opening a Modal window from another Modal window

Hi All,
I am opening a Modal window from a Modal window which has applets in it. But when the child modal window opens up from parent modal window, the applets on the child modal window are not loading properly. But when I change the child modal window to normal window, then applets loads fine.
I just want to know how different is a modal window when compared to normal window when it comes to applets.
This is the problem which showed up only on specific machine but not on all the machines.
Is this because of some specific settings or could be any other reason?
Any help Pls!!!
Regards,
Rajesh.

Christian,
This problem is occuring on 2 machines which has Java 1.5. But rest of the machines which has 1.5,1.6,1.4 are supporting modal windows. So not really sure whether its a browser issue or JRE issue or it is how the modal windows behave in an inconsistent way. Really need a solution for this problem as early as problem.

Rajesh.

Opening an applet window from a button in a frame.

hi,
i designed a frame,in that i took coordinates from the user in the Jtextfields and a button.i need that when user clicks that button,a new applet window should get opened and the line should be drawn(g.drawLine in the paint method) according to the coordinates passed.
please help me.

Yes, It works on firefox. It is only an issue with Internet Explorer.
However our web based application has to use IE and therefore when it calls apex it is in an IE browser.
I am really just producing a csv file, and opening it in excel. If this was fixed (or customisable in some way in IE that would help)

Opening a popup window from another popup

Hi,
I want to know if a popup window can be opened from another popup window??
Iam trying to do this from a JSP page
<td><a href="../common/help/Help_FAQ.html" onClick="return popup(this, 'FAQ','width=900,height=500,scrollbars=1')">FAQ.Now I have another link in FAQ page, which when clicked , rather than opening a separate full size window, overlays on the FAQ window with the FAQ window width and height.
Any help is appreciated.

Thanks.
It was a mistake on my end.
Instead of having <script type ="text/javascript"> I had only "javascript"
and the page was not picking up the function .
Now,, It is solved.

Hi, i would like to send particular APDU from one applet javacard to another and if its possible how could i make it.

Yes, it is possible.

- Applet2 implements a shareable interface object (SIO)
- Applet1 contacts applet2 through SIO
- Applet2 process the apdu and optionally passes a response message
Check out JCRE spec 2.2.1/2, Shareable Interfaces

Safari won't open to 'all windows from last session'

Safari is set to open to 'all windows from last session' - but it opens to a blank page. Not every time, but 75%+. I usually have multiple tabs open, not always the same ones, and this is slow, annoying and tedious to frequently reconstruct where I left it.
Any ideas?
I just moved to a MacBook from Windows and I am surprised to have an issue like this crop up so quickly (or well ever - based on Apple's reputation, that is - and all the glowing things my firends and associates have told me)

Open a Finder window. From the menu bar click Go > Go to Folder
Type or copy / paste the following:
~/Library/Caches/com.apple.Safari/Cache.db
Click Go then move the Cache.db file to the Trash.
Quit and relaunch Safari to test.
BTW, if you enable the Develop menu you can empty the Safari cache easily instead of having to go through your user library.
From the Safari menu bar click Safari > Preferences then select the Advanced tab.
Select: Show Develop menu in menu bar
Then from the Safari menu bar top of your screen, click Develop > Empty Caches

"open in new window"- from favorites panel - bridge

Hi Bridge, I love your way of working
However 2 things make my hair rise
- I can't "open in new window" from a favorited location. only in the "content" panel... which is rather "weird"
- I have to "reveal in finder" to be able to zip/rar files.
Please fix this, I know i am not the only one who would love this.

- I can't "open in new window" from a favorited location. only in the "content" panel... which is rather "weird"
To be honest, I never thought about that option, I always use the shortcut cmd + N for a new window and point to a folder in either folder panel or favorites panel. There is always something to learn
Having the same option in Favorites as in Folder panel would be very logical indeed!
- I have to "reveal in finder" to be able to zip/rar files.
I think you are bound to do so always because Bridge is in fact a browser and in itself not capable of editing files. The export panel did some tasks with resizing but has been discontinued in CC.
Only if Adobe made an application to unzip or open other packages the possibility for using the tools menu and reach the start up script for such app would be the shortest road possible to my knowledge. But also AFAIK Adobe does not offer such application.
And using MacOsX 10.8.4 my downloaded zip files are unzipping themselves automatically...
Please fix this, I know i am not the only one who would love this.
This won't work because this is a user to user forum, use the feature request option here:

When I open a new windows from my current tab background turns black. Can this be disabled?

I use Remedy and when I open a new windows from my current one my background turns black. This started when I moved to the new update. Is there anyway to disable this?

Is there a way to open a new window from the "Go" menu in Mavericks?

Before Mavericks, I was able to go from the Finder to the top menu "Go" -> "Utilities", or Applications or Home… and a new window would open.
Now I have to manually open a new window to avoid loosing my existing window.

Is there a way to open a new window from the "Go" menu?
First, as others have already stated.....make sure the checkbox is deselected for "open folders in tabs instead of windows" in Finder Preferences.
If you're like me and don't like tabs very much, there is a way to make folders always open in windows with a simple click (I'm using Mavericks 10.9.5). Go to a root folder (for example, the Documents Folder), open it, and select View > Hide Toolbar, then all folders within that root folder will open in a new window.
As an alternative method, any folder can be opened in a new window by holding down either Command Key while clicking the folder. But sooner or later you will forget to hold down that key, and then clicking on a folder will open in a tab (which will automatically resize the window and cause much aggravation).
The Hide Toolbar trick will also work with any folder present on the Desktop. It will make all folders inside that folder open in new windows.
To make the Applications Folder open in a new window when opening it from the menu bar at the top of the screen, you will have to open the main hard drive folder and use the Hide Toolbar trick. This will cause all folders inside it to open in new windows.
Hope this helps.

I attempt to open a second window from the icon but it does not open then when firefox is closed it will not reopen because it is still running in processes but no window displayed until you kill the process and then restart firefox.

I attempted to open a new window from the Firefox icon but nothing happens. I then went on browsing and closed Firefox but was later unable to open it. I checked processes and it was already running but there was no window displayed. I am running Windows 7 Professional.
This is repeated any time I already have the browser open and wish to open a second instance.
