Custom does not control loses focus on OS 4.6

I have a wide scope to create a custom button. It works fine on OS 5.0 but on 4.6 button is not to draw the sound style not targeted in order to always stay focused or draws the focus/unfocus events randomly.

Here's the code I used:

protected void paint(Graphics graphics) {
    if (isFocus()) {
        graphics.setColor(Color.LIGHTGREY);
        graphics.fillRect(0, 0, Display.getWidth(), mHeight);
    }
    else {
        graphics.setColor(Color.WHITE);
        graphics.fillRect(0, 0, Display.getWidth(), mHeight);
    }
}

I solved it by calling invalidate events onFocus and onUnfocus.

    Hello

    Firstly the Toshiba Power Saver requires the installation of the common Module.
    The common Module for Win XP v1.00.05 can be downloaded from the European pilot page Toshiba.

    So before installing the energy saver, install common Module, restart the computer, and then try the energy saver.

    In addition the Intel PROSet/Wireless Software can be used only with the Intel Wlan card.
    Is the laptop supports the Intel wireless network adapter?

    AFAIK the L300 series can be equipped with a Realtek, Atheros and Intel Wlan card

  • Can we use Office default memory offline if the customer does not have enough free memory?

    Can we use Office default memory offline if the customer does not have enough free memory?

    Yes. We can use the parameter offlineDesktopDefaultMemoryScaleupValue jointly with the offlineDesktopReportedHostMemoryValue parameter in the registry.

    For example, if your client system has 2 GB of memory and the desktop view is configured to require 2 GB of memory, you won't be able to check the desktop view because low memory is also necessary for visualization of hosted customer.

    Use the parameter DesktopReportedHostMemoryValue = 2048 registry offline, so that you can go to the desktop and use the registry parameter offlineDesktopDefaultMemoryScaleupValue = 1024.

    so that the desktop view uses only 1 GB of memory when run locally.

    Reg patch: HKCU\Software\VMware, Inc. \VMware VDM\Client\disableOfflineDesktopMemoryScaleup

    Note: If it's a small environment you can do manual. Or we can simplify this activity by creating a group policy.

  • Customer does not understand the purpose of the Service Packs

    I have a client and I have trouble explaining a question related to the objective of the SPs. Any comment is appreciated.

    The customer has a computer that runs an application with SP2 and creates a file on this computer. Then send the file
    a user to overseas using a computer with SP1. The user overseas to have problems with the file,
    try with another computer SP2 and everything is OK.
    I told the customer that the problem may be something in the file and it is not related to the compatibility of the SP1 - SP2. He
    insists that SP2 must be compatible with SP1. I tried to explain, Ms is not a new version, it corrects bugs etc...
    and we never talk about compatibility between SPs. SPs are not meant to create problems, it's to solve problems.
    I won't give the name of the application because it can see the post. He has now decided to roll all the computers
    back to SP1 I don't aggree with him.

    What do you think?

    Thank you.

    I think that the customer is a fool, and you need to stop doing business with him if he does not understand or accept what you say. Make sure he knows its computers run a serious security risk, and operational risk, and some programs may not work without the latest service packs, and it will be very expensive to repair.

  • setSelectedIndex (index) on a ListField call does not set the focus to the index.

    Hi all

    I have a ListField I show in a popup. When the listField is displayed, the focus is not set to the game past index.

    Can someone please tell me what is missing here:

    ListField choiceList = new ListField() {
        protected boolean navigationClick(int status, int time) {
        int index = this.getSelectedIndex();
        fieldChangeNotify(0);

        return super.navigationClick(status, time);
    }
    choiceList.setChangeListener((FieldChangeListener) uiFilter);
    choiceList.setCallback(new PopUpListCallback());
    add(choiceList);
    choiceList.setSelectedIndex(6);
    choiceList.setSize(choice.length, _selectedIndex);
    choiceList.setVisualState(VISUAL_STATE_ACTIVE | VISUAL_STATE_FOCUS);
    

    set the size and choices first, then the selected index.
    If this does not work, try invokelater for the index.

    Hi Elizabeth,.

    have you tried to rename all of them.

    Usually, it will not help change them. This does not display them in another way.

    I have their name at the beginning of XXX_v01, XXX_v01, and after finishing their I name them XXX.

    I try to use my XBOX on my PC wireless controller, it seems to be installed correctly (that is, it is correctly identified in the list of devices [as 'XBOX 360 wireless controller via Play and Charge Kit,' which is how it is connected], identifies correctly connected to the USB port [I moved it a few times to check]).  But it does not work for the 2 games I tried (BioShock 2 and Tomb Raider, both downloaded via Steam).  One of the games (Bio2) even has an option to enable or disable the XBOX controller, but when I try to click on the button 'ON' it will not activate, and 'OFF' option remains on.

  • Where to put my custom formatting does not control tips?

    Who, who know or have experience with it:

    Indicators of control provides solutions for possible all formatting needs. For example, I need to display only the last four digits of social security numbers (that is, for "123-45-6789", display ' *-*-6789 "" "). Another column of data table stores the school that YYYYMM, for example, 200902, 2009 is the year and semesters 02 is the month that represents spring (MM can also be 06 and 09 representing summer and autumn). I need to display the half in a more user-friendly way (i.e., for "200902" displays "spring 2009" "). Of course, I can't change the format of data in the table; I seek only to format the display of the data.

    I think it takes only a few lines of java code to do these by splitting the string in formatting strings, replace some of them with appropriate new values, and then put back together them. But where to put this code? All documentation covers this topic?


    Newman

    You can place this code in the getAttribute method in the EO or VO implementation class.
    (Create them via the Java node in the dialog VO or EO).

  • OperateSplitter does not control recall

    The online help for SP1 CVI2009 OperateSplitter () said:

    • Use this function to mimic the movement of a splitter of the interactive user control.

    Unfortunately, this is not quite true:

    If the separator is a point of order, this reminder is executed when the separator is moved with a drag of the mouse, but is not executed when the separator is moved by (OperateSplitter)

    It is easy to see that by running the provided example \CVI2009\samples\userint\events.cws, adding

    OperateSplitter(panel, PANEL_SPLITTER, width - gPanelWidth);
    

    line 159 of the events.c

    When you resize the Panel, you can see that the PANEL_SPLITTER callback is not called.

    When you move the separator, even with the mouse, the callback is called.

    Is this expected behavior?

    As has been pointed out, the events are not usually sent following a programmatic action. The recall and the events are there to let the programmer to react to the * user * actions. When the programmer initiates the action, an event letting you know that the action took place, since you launched it is necessary.

    In this case, you could do all that the recall made after the call to OperateSplitter (or call the callback yourself).

    OperateSplitter exists so that all controls set to the separator will be size or moved as if the user ran the separator, as opposed to simply by changing the position of the separator (which is how SetCtrlAttribute with ATTR_LEFT or ATTR_TOP).

    Hope this helps,
