Wheel, click on its use for listfield

Hi all

Uses 2 screens in my application.

both screens consist of listfield.to navigate screen

in an another am using the KEYCHAR property.

 _screen.addKeyListener(new KeyListener() {   

         public boolean keyChar(char key, int status, int time) {
             if (key == Characters.ESCAPE)
                 return false;
             if (key == Characters.ENTER) {
                System.out.println(_list.getSelectedIndex());
                 if (_list.getSelectedIndex() == 0)
                     pushScreen(new ascreen());
                else if (_list.getSelectedIndex() == 1)
                    pushScreen(new ascreen());
}
}

Instead, I need to implement the click wheel.

I've seen some of his related subjects, but I just couldn't do it.

can someone guide me to solve this problem?

You do _screen a subclass of the screen, and the substitution of navigationClick in the subclass. Something like this might work:

MainScreen _screen = new MainScreen() {
    protected boolean navigationClick(int status, int time) {
        // ....
    }
}

UiApplication does not implement navigationClick (int, int), which explains why you receive this warning.

  • Its use for excess application

    Hello

    I have some difficulty to understand how things are calculated as VROPS. It's my cluster, and this is the graph of the CPU load. Q - How demand may exceed its use if all my processor Cluster resources are not used? Also, if this is the case, why is the partition of the workload to 68 (which is good)

    grab.png

    Thanks for your help.

    Is that your virtual machine workload, overall, asks more it is given.  If you see the line stacked under the aggregate, you will see a virtual machine that is RED. I suspect that the VM which is in the Red contributes to your application being so high. Without this VM RED into the mix trying to swallow up all of your CPU, you demand would be much closer to its use. The chart does not appear that your cluster is out of ability, in fact, you see that the request is clearly ~ 50-60% of the capacity of cluster.  value of 68 for the workload would be the metric of the workload more limited of those chosen in the policy of cluster for the workload under the section "analysis."

  • CPU only runs at 25% of its use for office

    I am currently running XP Professional with Office 2003 on a Dell I5 (four core CPU) machine with 4 GB ram. I recently discovered that the system would not delegate more than 25% of the CPU for my excel or access. Sometimes, I have to wait for minutes for the automatic calculation. My company, IT supports is not aware any configuration that would cause this issue. Anyone know the reason?

    You misread my reference to Disk Defragmenter. My request was not fragmentation but the report sometimes reveals information about the system.

    With Excel you can benefit in some cases use macros to update the information. Several linked files can create heavy demands on a system.

    To explain what I mean an example would be to have a daily report with multi links to the report of the previous days. Thus the report day 2 would not insist the system but the report updated 365 can do. If the report continues to grade 2, the situation becomes more and more demanding on the system. Link to previous versions of files update the links to each linked file.

    Another thing that could apply, is that you can get situations where the virus of security system checks the files with macros. This would happen when the links are automatically updated.

  • When I open a web page any using firefox, its ok for a few minutes, then he opens another page saying it is redirected for no reason at all

    When I open a web page any using firefox, its ok for a few minutes, then he opens another page saying it is redirected for no reason at all, the homepage remains open, but the other page start for no reason at all in another tab

    It's very consistent, he arrives a few minutes? In this case, I suggest this test:

    To find out if one of your extensions is the culprit, could you test mode without failure of Firefox? It is a standard diagnostic tool to disable some advanced features of Firefox and extensions. More info: questions to troubleshoot Firefox in Safe Mode.

    You can restart Firefox in Mode safe mode using either:

    • button "3-bar" menu > "?" button > restart with disabled modules
    • Help menu > restart with disabled modules

    Not all add-ons are disabled: Flash and other plugins still works

    After stops in Firefox, a small dialog box should appear. Click on 'Start mode safe' (not reset).

    Any difference?

  • Its use and the demand for capacity

    Hello ps vRO community,

    I love ps vRO and there are many things that I would like to know. My question is why the workload (always) shows memory usage greater than demand and capacity, however there is no pretense.

    Thanks for the help,

    memory.JPG

    If the workload was 100% and its use has been 100% you would really use all the capacity of this virtual machine. If the workload was 120% and its use was 100%, you will have to add 20% more memory to meet the demand for this virtual machine.

    If the workload was 25% and its use was 100% you would really use 25% of this memory. You still have plenty of ability on the virtual machine, and depending on how stable that is 25%, you could probably reduced the memory of half and still be okay.

  • Its nothing to do with Photoshop, but is photodeluxe 4.0 free to use for commercial use?

    Hello

    I install photodeluxe home edition 4.0 on my work laptop, however, I'm not sure whether it can be used for free for commercial use. Given that it is a software abandoned and was told that its kind freeware so just want to confirm if it should be installed on laptop?

    If you could please provide any sort of link that proves.

    Much appreciated in advance.

    If you have a license (CD, serial number, etc.), then you can always use it as per the license.  But it is quite old and unlikely to work well on modern versions of operating system.

  • Photo Album using for screen saver

    I would like to use a photo album for my screensaver. I did it in the past with iPhotos and Photos.

    Using OS 10.11.16 on MacBook Air

    Photos 1.5

    I moved my old library of Photos on a hard drive that I needed storage space.

    Succeeded in creating a new photo library.

    Went in system preferences to set up the screen saver as I did in the past.

    Can 'see' the new photo library, but it is shaded on so I can't choose it as my screensaver.

    I opened and closed applications and restart the computer.

    I could choose a picture of pictures for my desktop image

    Have you turned on the photo library as your system library system in Photos preferences > general tab, after you have created the new photo library?

    "Use as a Photo library system" option should be grayed out in the Photos > Preferences > general, when you view the library you want to use for your saving screen and with other applications.  If 'Use as a Photo library system' is not grayed out, click it.  Then log market once again before trying to activate your album as a source of the screen saver.
