Launch app with params as front process and wait?
Hi, I was working with NSTask and came across some issues. I searched on the internet and found that there has been a similar query but that didn't have any solution. The link for that is http://lists.apple.com/archives/cocoa-dev//2003/May/msg01468.html. Could you suggest any possible solution for this. Also, if my parent application has a non-modal dialog up, on launching another app, it goes behind the non-modal dialog. Please suggest some solution as I am stuck with it for last few days.

Re: Launch app with params as front process and wait?
Hi Ken, Thanks for the prompt reply. I got a better insight into the APIs. But somehow I am not able to fix my problem. I am using following: NSTask* task = [NSTask launchedTaskWithLaunchPath:@path arguments:args]; int pid = [task processIdentifier]; ProcessSerialNumber psn; GetProcessForPID(pid, psn); SetFrontProcess(psn); [task waitUntilExit]; SetFrontProcess(psn); Even on switching to NSWorkSpace doesn't seem to solve the purpose. The launched application does not get highlighted. Also, one more issue I am facing is how to send custom events from launched application to parent application. Thanks in advance.

Please suggest some solution as I am stuck with it for last few days. To launch a secondary application, you should use NSWorkspace or Launch Services. That will bring it to the front, even if it's already running. To wait until it's finished, you can use the techniques outlined in this tech note http://developer.apple.com/mac/library/technotes/tn/tn2050.html . If you need to pass information into the other application, and you control the implementation of that application, I recommend using one of: * -[NSWorkspace launchApplicationAtURL:options:configuration:error:] with the relevant information in the configuration parameter * -[NSWorkspace launchAppWithBundleIdentifier:options:additionalEventParamDescriptor:launchIdentifier:] with an AppleEvent descriptor * LSOpenFromURLSpec() with an AppleEvent descriptor in the passThruParams fields of the inLaunchSpec parameter You can also pass information into the application through a scripting interface. If you don't control the implementation of the other application and the above techniques don't suffice, you can use NSTask to launch it, but it wouldn't be my first choice. If you need to bring it to the foreground, you'd want to use NSWorkspace to monitor for when it's launched and ready, and then activate it. You know when it is launched when you receive the NSWorkspaceDidLaunchApplicationNotification notification which matches the application that you ran. On 10.6 and later, you get an NSRunningApplication object with that notification, and you can activate it by invoking -activateWithOptions: on it. For 10.5 and earlier, you get a dictionary that includes a ProcessSerialNumber, and you can use SetFrontProcess with that.

Setting front window when launched from another application
Hi, I am facing some issues with setting an application as front process when it is launched from another application. Basically, I have a parent application A. When user performs certain action, the parent application launches another application B. It does so by doing fork(). In child process, it launches the application B by calling execv(). In parent process, it runs an event loop in which it waits for events received from B. It is basically done to avoid user interaction with application A. Only when the user is done with application B, it can interact with A. Now, what happens is that on launching B from A, B does not come to focus. Even on explicitly setting B as front process, the issue does not get solved. One more issue I am facing is that when some modal dialog is up in A and then I launch B, it goes behind the modal dialog. Could you suggest some possible solution for this.

Re: Setting front window when launched from another application
So, is there any way to prevent the user interaction with the parent application and still keep receiving events from child application.

It does so by doing fork(). Whoa — don’t do this. GUI apps should be launched by calling LaunchServices (or NSWorkspace, which is a wrapper around it.) One of the effects of failure to do this is that the frontmost app doesn’t relinquish its frontmost status, so the new app can’t claim it and become frontmost. There are other issues too. —Jens -- Gaurav Srivastava Btech CSE MNNIT,Allahabad ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Setting parent window
Is there any corresponding function call for ::SetParent(in Windows) in Cocoa? Basically I have a parent application from which I have to launch another application. I want the child application to open as modal within the parent application and not as a separate application. I have the window handles of both applications. I tried using [NSWindow setParentWindow] but this was not working for me. Is there any possible solution? -- Gaurav Srivastava ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
