Problem scrolling in PopupScreen

Hello

I added a PopupScreen to my application that will display a given text. When the text is displayed, scroll arrow appears indicating that there is more text to be displayed, however it doesn't let me scroll when I click on the down (tests on a BlackBerry with a trackball).

The text is displayed in a LabelField (which I believe is not Focusable by default), but even when I say new LabelField ("text", Field.FOCUSABLE), it still doesn't let me scroll down. I tried to add other areas (for example, EditFields) and it seems to work. So I think the problem is with the update?

Can someone tell me why this is? Here is my code:

package com.kflicks.ui.Screens;

import java.util.Vector;

import net.rim.device.api.system.*;
import net.rim.device.api.ui.container.*;
import net.rim.device.api.ui.*;
import net.rim.device.api.ui.component.*;

public class SynopsisScreen extends PopupScreen implements KeyListener {

    Vector results;

    LabelField label;

    public SynopsisScreen(String synopsis) {
        super(new VerticalFieldManager(VERTICAL_SCROLL | VERTICAL_SCROLLBAR),
                Field.FOCUSABLE);

        label = new LabelField(synopsis);
        add(label);
    }

    public void close() {
        UiApplication.getUiApplication().popScreen(this);
    }

    // ///////////////////////////////////
    // / implementation of Keylistener
    // ///////////////////////////////////
    public boolean keyChar(char key, int status, int time) {
        // intercept the ESC key - exit the app on its receipt
        boolean retval = false;
        switch (key) {
        case Characters.ENTER:
            break;
        case Characters.ESCAPE:
            close();
            break;
        default:
            retval = super.keyChar(key, status, time);
        }
        return retval;
    }

    /** Implementation of KeyListener.keyDown */
    public boolean keyDown(int keycode, int time) {
        return false;
    }

    /** Implementation of KeyListener.keyRepeat */
    public boolean keyRepeat(int keycode, int time) {
        return false;
    }

    /** Implementation of KeyListener.keyStatus */
    public boolean keyStatus(int keycode, int time) {
        return false;
    }

    /** Implementation of KeyListener.keyUp */
    public boolean keyUp(int keycode, int time) {
        return false;
    }
}

Try to exchange your LabelField to a RichTextField and see if that solves your problem.

  • ListView problem: scrolling non-stop

    Hello friends,

    I get some problem with ListView in ScrollView ListView doesn't stop scrolling.

    I want to put some of the views (for example, Label, textArea Image) in the vertical stack layout container & add a list at the end of the container, so that all opinions can scrolls.

    But I get unexpected results that everything is ok, but my view of the list doesn't stop event of scrolls of the item in the scrolling list.

    If I add some other view as tab after ListView then it never reached.

    Can someone give me a solution for this.

    Thanks in advance

    I use the following code for QML

    import bb.cascades 1.0

    {Of container

    background: Color.Yellow
    maxHeight: 1000
    preferredHeight: 1000
    ScrollView {}
    maxHeight: 1000
    preferredHeight: 1000
    {Of container
    {Of container
    topPadding: 10
    leftPadding: 10
    rightPadding: 10

    {Of container
    layout: {StackLayout}
    direction: LayoutOrientation.LeftToRight
    }
    TextField {}
    hintText: qsTr ("toEmail/Mobile number Email/Mobile Number") "") "
    }
    ImageButton {}
    defaultImageSource: ' images/add.png.
    pressedImageSource: ' images/add_focus.png.
    verticalAlignment: VerticalAlignment.Center
    horizontalAlignment: P
    }
    }
    {Of container
    topMargin: 10
    layout: {StackLayout}
    direction: LayoutOrientation.LeftToRight
    }
    ImageView {}
    preferredWidth: 120
    preferredHeight: 90
    }
    TextArea {}
    maximumLength: 50
    hintText: "title."
    preferredHeight: 180
    }
    }
    background: Color.LightGray
    preferredHeight: 720
    }

    {To ListView
    dataModel: {ArrayDataModel}
    ID: contacts
    }
    }

    onCreationCompleted: {}
    contacts. Append ("ABAC");
    contacts. Append ("ABAC");
    contacts. Append ("ABAC");
    contacts. Append ("ABAC");
    contacts. Append ("ABAC");
    contacts. Append ("ABAC");
    contacts. Append ("ABAC");
    contacts. Append ("ABAC");
    contacts. Append ("ABAC");
    contacts. Append ("ABAC");
    }
    }
    }
    }

    As far as I know, using listview in scrollview will cause infinite scrolling. To resolve this issue, try to set the height of the listview. You can also try to set the height of the listview based on the number of records by using contacts.size ();

    It will be useful.

  • Problems scrolling with TitleBarScrollBehavior default, NonSticky - Q10, Dev Apha C

    I'm having a problem with the default behavior of the title bar when run my apps on Dev Alpha C Simulator and the device, with the latest operating system.

    If the title bar is set by default or NonSticky, he will hide quite well.  However it will then parade not beyond the limit of the screen height + hidden title bar height.  A simple example, I have a screen with ScrollView containing a number of LabelFields, of which 3 are hidden.  If I scroll up, the title bar will disappear, which is good and I can see the label located slot, but when I let go, the screen hangs on back order as the top of the screen eo the immeidately field under the title bar, which of course hides the last LabelField.

    While I can go through my QML and together

    TitleBarScrollBehavior.Sticky

    This means that I wil have create a version 10.1 specifically for the Q10.

    I searched and found no referecnes in this as a problem, but I don't know that other people have noticed it.

    It is fixed with 10.1.0.1485.

        }
    
        protected boolean navigationMovement(int dx, int dy, int status, int time) {
            if (!_editField.isFocus()) return true;
            isNavMovement = true;
            if (dx > 0 && (_editField != null) && (_editField.getText().trim().length() < _editField.getCursorPosition())) {
                if (dy != 0) { return super.navigationMovement(dx, dy, status, time); }
                return true;
            }
            return super.navigationMovement(dx, dy, status, time);
        }
    
        protected boolean touchEvent(TouchEvent message) {
            isNavMovement = false;
            return super.touchEvent(message);
        }
    
        public int getPreferredWidth() {
            return managerWidth;
        }
    
        public int getCursorPosition() {
            return _editField.getCursorPosition();
        }
    
        public void setTextFilter(TextFilter textFilter) {
            _editField.setFilter(textFilter);
        }
    
        public void setMaxLength(int length) {
            _editField.setMaxSize(length);
        }
    
    }
    

    Something immediately suspicious is this line in your navigationMovement:

    if (!_editField.isFocus()) return true;
    

    This means that if you're not focused, you consume the event! It's the opposite of how you must treat. It returns false.

    Check your two channels of (dx > 0 & _editField! = null & _editField.getText (.trim ()...)) (check at lower to equal, another checks the action is the same) can be combined into one with<= (less="" than="" or="">

    Your equals._editField.getManager () is redundant - you do not _editField add to something else.

    Super.sublayout followed by setExtent is very risky - you confuse just the super class. Remove setExtent - defined properly by super.sublayout anyway.

    So a lot of this code is problematic, and it is difficult to pinpoint the exact problem. In addition, there is an article in the knowledge base that provides a good starting point for exactly this kind of gadget:

    A scrolling line text entry field

    Be sure to read the comments - they discuss borders and some other stuff. In addition, this article is referenced in many threads here, where people discuss problems and potential fix. See if it suits you.

  • Problem scrolling on iPad

    Hello!

    We have a course of eLaerning published by Captivate and we display via an iframe on our Web site, but when we see this on an iPad we cannot scroll on it. You have to scroll by sliding on an area of a Web page that is not in the iframe.

    I tried to use the usual fix -webkit-too-full-scrolling: touch! important; but this and nothing I try works.

    Anyone know how to operate?

    Thank you!

    Yes, that's what I tried, the code was fine. It is the release of Captivate that was causing the problem.

    When I published the course for "mobile gestures" option has been activated. I have this off and I managed to scroll properly. Thanks for the help!

  • problem scroll down in an article

    Hello

    I have this problem of wird.  I will create a pdf portfolio and when I scroll down in an article gets stuck between pages or appears only part of another page and then returns and doesn't let me go down.

    a few considerations:

    • get off only at the second attempt

    • only happens in pages with MSO or scrolling images

    • If I create the same folio to jpg, it works very well

    Any ideas?

    Thanks in advance

    Pedro (Portugal)

    Hi Pedro,

    I have confirmed that it is a matter activated when scrolling in PDF articles MSS. Unfortunately the fix for this was too risky to enter the version 24, and we will in version 25.

  • V20 problem scrolling images

    Hello world!

    I have InDesign CS5.5 and I'm having a problem with the new functions of scrollable frames.

    I tried to recreate a framework like the one shown here floating tv.adobe.com/watch/learn-digital-publishing-suite/scrollable-frames-and-pan-zoom-v19/ at 03:43.

    My problem is:

    Hide indicators Scroll does not work

    Use the Document Position does not work too.

    I installed the latest tools producer (FolioProducerTools-CS55 - 1.10.1 and FolioPanel-CS55 - 12.2.2.1).

    I am running Windows (that's the problem here?:-P))

    I have de - and reinstalled the tools of the producer.

    I also tried on my computer windows laptop. Same result.

    Do I need to install anything else to make it work?

    Maybe someone can help me here.

    Best,

    Wolfgang

    Post edited by: Onefootvisual19 I uninstalled the Folio Tools 1.10.1 v producer and installed s 1.8 v (where the scrolling function framework was not available yet) installed v 1.9 (the service sought as described above did not work) and finally reinstalled v.1.10.1. It still does not...  I'm the only one who experienced these problems?

    Here are three screenshots to illustrate my problem.

    (1.) I have the red box is the container for the grouped elements that enable scrolling (on the left side is the entire element so you can see). Hide indicators scroll option is checked and also use the document position.

    screen1.jpg

    2. when I start the scrolling frame content viewer puts content on the upper left corner...

    screen2.jpg

    3 and scroll indicators are visible

    screen3.jpg

    What is the problem here?

    Can someone help me?

    Best,

    Here's another weird thing:

    I looked upward http://www.caniupdateadobedps.com/ and they say that you will find the version number of dps in the Info window of the folio builder Panel. it should be 20

    but mine says 15? However, I have installed v20 now for the fifth time.

    version_screen.jpg

    the extensions manager says I v20 however.

    version_screen_extension.jpg

    Is - what the cause of my duties of dps does not as they should?

    I would really appreciate some help here.

    Dear Neil,

    Thanks for pointing the right direction.

    Here's the deal:

    After I deleted all the pieces you described and reinstalled the tools that this still does not work, but I noticed in the extensions manager that the plug-in was still active and in the location where I installed InDesign CS5.5. I still once uninstalled the tools and also to delete the "(ressources DigitalPublishing) folder" and the plugin 'DigitalPublishing.apln' (which is the year 2011). "

    I reinstalled the tools and then start InDesign CS5.5 Panel window told me, I'm missing a plug-in and I should download the latest tools producer.

    Here's the trick: I copied the newly created (after reinstall new tools) "(DigitalPublishing ressources)" and the "DigitalPublishing.apln" C:\Program Files (x 86) \Adobe\Adobe InDesign CS5.5\Plug-Ins\Graphics to the location where I installed InDesign CS5.5 and it works! "

    Neil, thank you very much for your time!

    You saved my day!

    Best,

  • Problems scrolling HP dv6

    I just purchased a dv6-3022nr yesterday and I can't find a way to scroll. A note in the box says to use two fingers, but I tried everything I can't scroll up and down with this tablet. Any suggestions?

    For the scroll function works, Synaptics touchpad driver should load on startup... Check whether what is happening...

    In addition, check if the option of scrolling in activate in the Synaptics touchpad properties. To do this, click Start and type mouse in the search field, then select mouse when it becomes available in the list of programs. The properties of the mouse settings window will open. Click the device settings tab. On the device settings tab, select the Touchpad device name, and then select settings. Click the plus sign [+] to expand the scroll and check if two finger roll is checked...

    If the driver settings tab is not is not, install the driver from here ftp://ftp.hp.com/pub/softpaq/sp49001-49500/sp49242.exe

  • masking problem: scrolling menu

    Hi, I have a drop down menu, but the image appears not when you preview. As suggested by others, I've changed the source of the image to png psd, jpeg, and none of those who worked. I also tried selecting TIME bitmap caching in the properties of the clip without success. someone at - it other advice? It works with flash 8 but not flash 9.
    Thank you!

    Nevermind, I answered my own question: the size of the imported image is larger than 8192 pixels wide which is apparently loading/memory problems.

  • XCode 8 - How to fix an Auto resize problem on XCode version 8.0?

    I used XCode version 7.2.1 for my project. But I updated version 8.0 of XCode now. The scrolling display is inconsistent in my project view controllers. Here I used resizing only not an automatic layout. I have mentioned the many forums. But can not able to find a solution for this. Here, I have attached similar links that I had tried.

  • Loss of function of mouse Scroll Wheel

    I took a leap and a leap of faith, the upgrade to Firefox 3. something to 11.0. I work through awkward differences in the user interface, but I'm having a problem with the scrolling.

    I can't put my finger on any particular website or the size of the page, but I find that sometimes my mouse wheel will stop working with Firefox and I have to use the scroll bar to scroll through a document. Once he goes, he went. I can move to another tab that previously scrolls with the wheel and it is no longer made.

    If I close Firefox and restart, the works of wheel scroll again (even with the page on which he left earlier. If I leave Firefox running, switching to another application, the scroll wheel works out there, so it is unlikely that the driver is corrupted.

    I am running Windows XP SP3 and Firefox 11.0 (downloaded and installed 05/04/2012)

    It is perhaps too early to know for sure, but I think that my problem, loss of the scroll wheel of the mouse in the web pages after visiting one or two particular websites and some time, navigation is not a memory leak problem as some have suggested, nor a funky extension, but rather a problem of mouse driver. I am using an IBM mouse brand with the driver bundled with it rather than the standard driver from Microsoft. removed the IBM mouse driver (and mouse) and installed a mouse of brand store using the standard mouse driver Windows XP. This has not hung up again within a few days of use.

    If I have a memory leak problem, I don't think I've met the result of it still. The program (which currently use 10.0.4 ESR) appears to be stable, no crashes, no crash and, Hooray! no problem scroll wheel mouse.

    I miss the function 'button magnifies' with the IBM mouse driver (it also works with the generic mouse when the IBM driver is loaded), but I would lose this function than to lose the scroll wheel and must exit and restart Firefox to retrieve.

  • Problem with window painted and scrollbars when editing (LabVIEW 8.0.1)

    I'm under LabVIEW 8.0.1 in Windows XP SP3.  For my main VI, I came across a strange problem about 5 months ago.  The front window - both in edit mode and run mode - arrested repaint itself on the right side which is no longer visible when you scroll from top to bottom, but also visible overlapping Windows.  Coinciding with the repaint problem, both bars scroll search disabled grey arrows and no boxes in the bars that you can click and drag to scroll the window.  The scroll bars work still partially if you pass the mouse over it and roll the mouse wheel but does not work by clicking and dragging.

    The façade has a lot of controls and indicators, including containers of tab control and is greater in the horizontal directions and vertical so the two scroll bars must be active.  But I deleted everything in the Panel before and everything in the schema and the problem persists.  If the problem is not directly related to a control/led display.

    I saved the simple VI to this problem (using a line of large text and a high box rounded to test), and then created a new VI and copied the two elements at the new VI.  This new VI didn't paint it and the problem of the scroll bar.  The two screws are slightly different in the memory usage and the revision number (bad is review 1785 and the good is revision 3), but otherwise the two screws are identical.  I have attached two screws at this announcement.  When you first open the bad VI, you will see the scroll bars disabled while the good VI has active scroll bars.  To replicate the repaint problem, scroll the window up and down with your mouse wheel.  If it's good when you first open the VI, click on another window, then click on the window of VI and try again the mouse wheel.  This by clicking sur-loin-and-return always causes the problem of repaint for me.  I tried the screw on two different computers, both running Windows XP SP3 and LabVIEW 8.0.1 with identical results.

    Here's what I discovered simple troubleshooting with the screws:

    always off scroll bars

    * repaint the problem in the main window for larger then 680 pixels of window widths

    * repaint the problem in the menu bar of the main window for widths of more than 646 pixels

    * entire window becomes disabled than 1348 pixels window width

    * can paint window minimize and restore, but only repaints only once

    * scrollbar boxes sometimes flicker in the display, but then disappear

    * Scroll left and right hovering mouse over the bar and horizontal scroll by using the mouse wheel

    I found something similar on this forum (thread: problem with refresh of façade)-it could be linked to the CAR on the Panel being offset internally.  I don't have access to LabVIEW 8.5 or later and do not plan to upgrade - I have not tried the trial version, as this user has done.  I could try to copy and paste my set of the block for a new VI diagram but the VI is so important I'm afraid something would break, plus I don't want to do it again in a few months.  The problem seemed to occur after a certain number of stops (or revision number).  I save copies of backup often and when the problem first happened, I was able to go to a previous version, make the missing changes and save it without any problem, but this only delayed the problem and he came later.  It is therefore perhaps the revision number.  It seems not related to a change or a particular addition in the front panel and the graph.

    The attached picture shows the repaint problems and scroll bar in bad VI.

    This raises a question I have - if this problem is a bug has been fixed in 8.5 and later, is it possible to apply bug fixes for older versions?  Or what I need to pay for an update fix these bugs?

    Seems that something got corrupted with this VI. Things to copy on a cool VI and things should be OK.

  • Scroll the issue in the model of "Influence".

    Has anyone else encountered a problem with scrolling on the phone model "Influence"? I had a website finished and thought when he went to live scrolling would not so nervous. When you arrive at the end of the page he pops up again, but this is not always the case and it is not always at the same point on the page? I restarted the site and finished, it's still once, not deviate the parameters models, scrolls etc. and it always behaves very nervous. Can someone please advise as to the address / solve this problems? I've asked this question before and was advised to adjust the effects of scroll, but as I had not touched these that initially I was wondering was there problems with the model? I would really appreciate some advice.

    Kind regards

    I created a test with the same model site but see no problem scrolling: http://influence-test.businesscatalyst.com/index.html

    Please let me know if you make reference to a specific part of the page, also if you have than a html embed trying to remove this and then check, also reset settings scroll to check.
