How pushScreen() works

Hello

I want to know how pushScreen() works.

I have 5 screens that extend screen. I'm not allowing onClose() method to close the form. I put onClose() to false.

When I first login screen appears. from there, I use pushScreen (SecondScreen()) new and like that of the second to the third, third in the fourth and

so now. I can call her first screen again to fifth or fourth screen using pushScreen (FirstScreen()) again.

Not where I close the screen, or use anti-pop.

The jvm maintains all instances of screens using new, I created.

What is the best practice to follow to push screens.

Thank you

Thanks for the reply.

Now I understand clearly.

I'll follow the way you explained.

  • How iCloud works for documents?

    So, I was working on a Word document between two different iMacs.  To keep the documents in sync, I have it stored the iCloud drive.  May 17, died the main iMac that I used to work.  Now I'm trying to restore the iMac that died, but I expected the document in phase.  When I went to my other iMac to continue working the iCloud drive shows the word document to have an update date of May 11.  Basically, I lost six days of work.

    I had assumed that iCloud drive could be used a shared drive between computers - like Dropbox or 1prediction.  But this isn't the case or something unusual broke my sync files to the cloud.

    So how does iCloud?  It is not synchronize whenever a file is updated, but uses another system?  I just want to understand how it works if it does not happen.

    Otherwise I could use Pages that seems to work as I expect to work the synchronization whenever there is a change, but in this case the word is the right tool, not Pages.

    Thank you.

  • How cache works on an iPhone?

    Thus, if only a topic has an application that he has legally downloaded on the apple App Store in memory cache, video/audio from youtube videos. And it "covers" any song you want.

    1.) does take space on the memory embedded phones (iPhone 16 gb)

    2.) after about 500 songs cached will there be performance implications? Because that I do not know if the cache is an accessible memory write is in and of its own which would get clogged after a lot of files are cached.

    3.) why can't I just check the size of the apps file to see if it uses the said files system memory "cached".

    BASICALLY, I FOUND an ALTERNATIVE to ITUBE, where songs are "cached" actually stored? Do not want to waste space that I have only a 16 gb iPhone

    1 - Yes

    2 - Yes

    3. I think because that's not how iOS works.

    Is your phone jailbroken?

    How do you think your phone to store the songs without taking up space?

  • Satellite U840W - how it works with SSD and HDD drives?

    American,

    I have a U840W which is a beautiful piece of work. He currently heads the Win7.
    It has a hybrid drive system, SSD 32 G and 500G HARD drive. Apparently the 32G acts as a cache.

    I tried to install Linux Mint as a dual boot with Win7.

    Cannot make it work. The installation process (Ubiquity) does not see disks or partitions.
    In a file manager or the GPart-partition manager, I see the HARD drive and all partitions.

    Help me to help the developers of the ubiquity of the problem of access to disks I can get a
    explanation of the way in which the disk system is organized and how it works?

    Any help greatly appreciated, Ian.

    The LINUX community already knows your answer and has led the path to resolve, such as the forum of mint as this thread:

    http://forums.linuxmint.com/viewtopic.php?f=46&t=124299

    Even Microsoft Windows has trouble with setup.exe on disc SSD/HDD hybrid and the Microsoft forums are polluted with their own unverified solutions, some of which are frighteningly superstitious that authoritative to be listed here.

    Ubi, Gnome and KDE are all based on the ability of Grub reliable start the player and so many different distributions don't guarantee reliability.

    I don't have the problem you describe with hybrid hard drives since the installation of 11 Unbuntu.

    Mint is not my first choice with the exception of a bureau of temporary replacement, since the authors are strongly focused on the Office UI, less than the largest army of coders behind Unbuntu and Fedora.

    I'm not criticizing the currency of your choice, but comparing the current Unbuntu boot process could shorten your objective dissection of a startup process of OEM from a manufacturer known for securing lower level specifications.

  • where to read how things work?

    I have a new HP G71 Notebook with Windows 7 Home Premium.  I can't find a source to give me simple answers about how things work. Example: I read the User Guide on how to remove a USB connection and he asks to go to the Notification area and click "surely remove material and Eject" but there is no such an indicator.  I have other similar things that are minor, but I've not found any route or information source that says really simple answers to simple questions. Everything seems adapted to a major outage or disaster.  Any suggestions on a resource that tells a person how some of these things work?

    Thank you, love

    Hi Robell, consider the bookstore and guides 'Fool' (the big yellow books with the Geek on the cover) in computer science/informatics. They are aimed at beginners as well as experts.

    Some online resources are here (and there are more choices without end).
