Programming list scrolling does not

For some very odd reason, I am unable to programmaticaly scroll my list. With the exception of the simple scroll() method which takes an offset of pixels, no other methods of scrolling the no matter what.

In addition, ScrollPosition and ScrollAnimation who hold constants, are apparently not available for my use. When I ctrl + space to see tips, suggestions are only ScrollMode and ScrollIndicatorMode.

ActionItem {
                        title: "To Top"
                        ActionBar.placement: ActionBarPlacement.InOverflow
                        imageSource: "asset:///images/ic_to_top.png"
                        onTriggered: {
                            messagesList.scrollToItem(1);
                        }
                    },
                    ActionItem {
                        title: "To Bottom"
                        ActionBar.placement: ActionBarPlacement.InOverflow
                        imageSource: "asset:///images/ic_to_bottom.png"
                        onTriggered: {
                            messagesList.scrollToItem(messagesList.dataModel.childCount());
                        }
                    },

Given that I could not access to the constants for the scrollToPosition() method, I tried to use the scrollToItem() that scrolls to a supplied index number. It does absolutely nothing.

Please, any help suggestions is welcome and appreciated.

Thank you!

Hello
scrollToItem expects a row which is a table consisting of section number JavaScript and article. The indexes are zero-based. Try:

messagesList.scrollToItem([1]) / / second item
or
messagesList.scrollToItem ([0, 1]); first section, second item
I'm not sure that it will work.

childCount returns a number of child elements in the section and uses an argument. For ArrayDataModel or GroupDataModel use the size() function. Valid range of items is 0.size () - 1.

  • Tecra A7-202: Touchpad driver virtual scrolling does not work

  • Scrolling does not work on some applications

    I use the program Notepadd ++ and I can't use the touch pad to scroll. I plugged in a USB mouse and scrolling works very well with this device. I tried reinstalling the drivers, etc., and it still has the same problem. Also scrolling does not work when you play videos flash on Firefox. Again, scrolling works very well when you use a USB mouse.

    Name of product: notebook PC HP Pavilion g6

    Product number: B5R80UA #ABA

    ih23,

    After doing a little research, it seems that programs are in conflict with the driver and you are not alone in this experience.

    Here's what I found to solve the problem in Notepad ++. Note to change the registry, depending on how comfortable you are with it or not, it's you if you want to try this fix or not. I always recommend to back up the registry before you change anything.

    "It seems that everything that makes the Synaptics driver to display the slider is confusing Notepad ++."

    "If you go to HKLM\Software\Synaptics\SynTPEnh and add a new DWORD value named UseScrollCursor with a value of 0, the slider will not appear and vertical scrolling will work in Notepad ++.

    Good luck!

  • On my trackpad scrolling does not work after the upgrade to 12.0

    On my trackpad scrolling does not work after update Firefox from version 3.6.28 to version 12. It normally works in Thunderbird, and other applications. It is a Lenovo T61 with XP Service Pack 3 and all drivers up to date. Version 3 seems to have bad memory leaks so I would like to upgrade, but I can't do it without scrolling. I would appreciate any advice.

    Try to change the pref ui.trackpoint_hack.enabled on the topic: page default config-1 to 0 or 1 to see if that makes the work button.

    Close and restart Firefox after changing the ui.trackpoint_hack.enabled preferably.

  • Scrolling does not work on Satellite Z30-A-1DJ

    Hello

    Summer on the internet trying to find an answer for my problem; How to make scrolling, pinching etc on my touchpad?

    Scrolling never works with this laptop (2 months) and up to now, even moving cursor was not reliable, since sometimes when starting the laptop touchpad was completely dead and has not reacted to what.

    Now there seems to be problems with it since I uninstalled the driver for the touchpad and restarted my computer, but still scroll does not work.

    Troubleshooting for this problem was no good.
    They all lead you to the first research of mouse in the start-> mouse-> advanced properties screen and from here you can adjust the parameters of mouse pad.

    I don't even have this tab on my laptop, while all the others are there (buttons, pointers, pointer, material options).

    How can I adjust the settings of touchpad on Satellite A-z30-1DJ?

    The characteristics mentioned touchpad should be accompanied by software as hardware.
    There are standards of touchpad different as Synaptics, Alps, but also momentum that support different features and different software.

    In the case where this software isn't installed or is not working, the touchpad to scroll as well as other features are not available.
    It could also be that tactile built-in module support no additional features.

    To my knowledge the Satellite A-Z30-1DJ should be equipped with an Alps Electric touchpad and this touch pad is different and does not support the same parameters as MOMENTUM or Synaptic touchpad.

    However, as you said, the additional parameters for touchpad Alps Electric are in
    Control Panel? mouse? last tab (Advanced)

    If you wish, you can try to install the driver for the Synaptics touchpad that has been released for other series of laptops as Portege Z10T-A

    I'm not very well if this Synaptics software would work correctly under the Alps touchpad m power but its definitely worth a try.

  • Synaptics touchpad two fingers scrolling does not work in the player to develop modern UI application Windows 8.1

    I have a HP Envy TouchSmart UltraBook 4-1161er. Two fingers to scroll worked well in all modern user interface applications that come with the pre-installed operating system Windows 8.1, but the situation changed after the upgrade to Windows 8.1. Now this excellent and very useful two fingers scrolling does not work in the updated reader application. How to make it work?

    If the problem is in the drivers, maybe, install the drivers the latest may correct this?

    I tried to find the latest drivers for the touchpad Synptics in my ultrabook on the HP website, but it's the same old v16.5.3.3, I already have (published in may 2013). Synatics official site contains a link to the latest touchpad driver pack v17.0.19. Can I install it?

    I would try to install the Windows 8.1 (64-bit) driver Synaptics touchpad available in the download section of your sleekbook web support before using compatibility mode.  If the current driver does not work for you, try the earlier versions available .

    If you have no positive results, then use the compatibility mode (select Windows 8) on all three Windows 8.1 synaptics touchpad drivers, starting with the most recent.

    To use compatibility mode to install the driver just softpaq to the right, click on the file and choose troubleshoot compatibility. Select Windows 8 and run the installer.

    I need help, vertical and horizontal scrolling does not work after the computer wakes up to the top of falling asleep or hibernating.  When I initially start the computer since the closure it works and it works again when I restart the computer.  I know how to change the settings for it, like one or two fingers to scroll and it turn on or turn off, but the settings are correct and scrolling still doesn't.
