How Manager dehighlight

Hi, I'm sorry if this question has been asked before, but I searched this forum and read the tutorials but still cannot find how to solve it.

I'm doing a screen filled with lines, and when each line is to the point, I want the entire line to be highlighted (a bit like how the entire line is highlighted in the mail we scroll down to the bottom). Note that each line is a manager of the horizontal line. Now, the thing is, even if I put it in the constructor for the handler of the horizontal row to be HIGHLIGHT_FOCUS, the Manager still doesn't highlight itself during the onFocus() event. That's why I've manually changed the background color of the Manager to imitate the effect light tone (if there is a way to highlight the fields or Manager, please tell me). However, now I don't know how to put it back as it was before.

Here's how I code line:

Line HorizontalFieldManager = new HorizontalFieldManager(Field.FIELD_LEFT |) Field.FOCUSABLE | Field.HIGHLIGHT_FOCUS | Field.HIGHLIGHT_SELECT) {}
           
protected void sublayout (int maxWidth, maxHeight int) {}
Super.sublayout (475, 50);
setExtent (475, 50);
}
           
protected void onFocus (int direction) {}
setBackground (BackgroundFactory.createSolidBackground (Color.MIDNIGHTBLUE));
}
           
protected void onUnfocus (int direction) {}
not knowing what to do. Tried invalidate() but does not work

}
};

Thank you in advance to those who can guide me

You can implement this by using ListField and implement your own drawListRow.

If you really want to do it from scratch, I did it by creating a custom implementation of the field, where I manage and paint lines the list individually. Not that big of a deal, I don't think. I had to do this to create lines of really custom list with multiple items of text/graphics within each line.

I've never tried what you try here, but I guess it should be possible.

    Autoruns is a great program for geeks, but for the average home user it generates so much information it can be a nightmare.

    Stick to the MsConfig - Startup tab in a 1st time, but start in programs and features when cleaning. You don't need to worry about something in the boot if you can remove the program anyway.

  • How managing RecoverPoint SRM VM test and actual failovers?

    Try to understand how EMC RecoverPoint manages failovers of SRM VM.   It deals with and the real test failovers differently?    For example, for failovers of test should I use SAN snapshots and real failovers promotes a LUN because failure could be a long time?   In addition, where these snapshots and LUN does work for?   The VNX target or some hybrids of VNX + RecoverPoint.

    I was not able to find an article on this architecture.

    Fix Matt, any block storage is provided by your VNX and all I/O will be finally served by newspaper or copy/data source LUN.  My apologies for any confusion!  On the performance, take a look at this blog post.  The author does a great job of outline quite unique I/O behavior of journal RecoverPoint and his unit number logic, something absolutely consider when the design of the VNX pools.  I personally always stick with standard FLARE LUN to reviews and never magazines supply workloads from one pool other accommodation, I don't have to.

  • How manage the Tuxedo to reconnect to base what database restart or failover to standby dataguard?

    Hi expert,

    My Tuxedo apps using simple to connect to the oracle database, do not use XA.

    All connect and disconnect statements written in code.

    In the situation, when the base data to restart or failover of dataguard standby database. I have to restart all the servers in Tuxedo to reconnect to the Oracle server.

    If I want to reconnect to the database in the application code. I need to know all the exception of disconnection and catch.

    ORA-00028, ORA-03135, ORA-01012 are all oracle error. perhaps than others, no list.

    Do you know how to enumerate all the exception?

    or is there a way to reconnect db connection all servers in tuxedos at the request?

    Thank you in advance,

    Chao

    Hi Chao,

    The answer depends on the platform and version of Tuxedo.  On Oracle Engineered Systems with Tuxedo 12.1.3, you can make use of our new RAC are supported features to handle this in a transparent way, in addition to getting better performance if you use RAC.  New support includes support for FAN so connections can be switched forwards an instance goes down for maintenance.

    For all other environments, I would say looking at TAF (application transparent failover).  TAF should be able to reconnect transparent to another instance or database dataguard.

    Kind regards

  • How manage/copy/track db in Oracle

    Hello
    I'm working on ORacle db dev, so we have a few changes on a daily basis, and then we're going to change the location of the most recent source of the journal for each object control: sp, package, DOF, etc...

    Is there any good auto tool to make the snapshot for the whole db and have all the definition for dbo in one place practical, we fundamentally new to ORacle and our mangmt approach is very careful, but probably not to count. I feel that Oracle should have some tools for this fancy.

  • The proSafe (JGS524E + GS116E) Switches: Configuration Management Web GUI in VLAN specific

    Hello

    I use a JGS524E and a GS116E. The two are connected via a 802. 1 q uplink with all defined VLANS in him.

    A 802. 1 q other interfaces goes to a pfsense firewall, which serves as a router and dhcp server for each VLAN that I use.

    How can I configure the switches plug are in one VLAN specific and get his IP address of the dhcp server in this VLAN?

    At present, it seems to be random access: it is not predictable that range from intellectual property, it takes its IP configuration via dhcp...

    How management function works internally?

    Thank you

    Markus

    Hello

    Thank you. I tried it out, but the behavior seems to be a little different:

    I configured a static IP address for the switch (10.1.0.13 / 24). I have access to the switch web gui via the ip address of the host of a host directly connected (connected via a trunk port, where I put 1 VLAN on the trunk), but it is all the same, what VLAN that I use:

    When it is connected to the VLAN 1 I have access, but also through 10 VLANS, VLAN 20 and so forth (assumed, I configure my computer appropriate staticly in the IP network, for example 10.1.0.20 / 24). So it seems not be limited only to the VLAN 1. You have access to each vlan, only the IP configuration must be in the same network.

    I'm not sure, how it behaves when cascading the two switches, I have not tried.

    If this information can be useful for other users with the same question about this switching product line.

    For me, this behavior is not very well implemented from my point of view. For security reasons, you must limit access to the administration, for example by allowing access from a specific hardware port or a vlan. With the effective implementation, centralized management for a cascade topology is not easy to set up, perhaps because the behavior is not very clear and not documented in the manuals.

    Mentioned on the edge: there is no available TLS/SSL encryption when accessing the web gui (not https). So the password is transmitted in clear text... not a very good idea, I think.

    Thanks a lot for your help.

    Best regards
