Issue#2256: Blackberry - How to acces Textfield text property on another qml page

  • Hi,

    I started BB 10 development recently and need some help. I searched this forum but couldn't find some information that exactly is related to my problem (the opposite way only), or I missing something basically. From my main.qml I want to access the textfield's text property from the InputControl.qml to use as a parameter in my SQLQuery (attached object). I tried to use the property alias fieldname method, but it doesn't work. I can't feature it out. Here is my code:

     

    main.qml

    import bb.cascades 1.4
    import bb.cascades.datamanager 1.2
    import bb.system 1.0
    import bb.data 1.0
    
    Page {
     
     id: root

     content: Container {
     
     leftPadding: ui.du(2)
     rightPadding: ui.du(2)
     topPadding: ui.du(2)
     bottomPadding: ui.du(2)
     
     InputControl { 
     }
     
     // The ListView that's used to display the artist data
     //! [1]
     ListView {
     id: myListView

    } // end of Page

    And here is my InputControl.qml

     

    import bb.cascades 1.4
    
     Container {
     property alias stext: txtSearchText.text
     
     Label {
     id: lblSearchText
     text: "Searchtext\r\n"
     
     }
     
     TextField {
     id: txtSearchText
     layoutProperties: FlowListLayoutProperties {
     
     }
     hintText: "Enter Searchtext" 
     }
    }

    Any help is greatly appreciated. Thanks.

  • Issue#707722: Blackberry - Group Text Message issue (duplicate to myself) with Passport Silver

    I upgraded from a blackberry torch 1.5 months ago.  Torch worked great.  When I am in a group conversation with people, everytime I respond back, I get my message back as a new text message within the group. I am with AT&T and they had me on the phone for over 1 hour and couldn't figure out.  My IMEI is correct with them but the picture of the phone itself does not show up on my profile.  Everytime I change it to a Passport, it goes back to a generic phone.  However, when I called them, they do have my correct IMEI so this could not be the issue. I did several google searches but didn't find anything. My routing preference is:  Circuit SwitchSend Text only messages as:  AUTOMATICRETRIES = 3 The problem is that when I am in an active group chat, I get a duplicate of my own message. For example, I reply to someone's message and it shows up as sent. Just a few seconds later, I receive my own message with my phone number in place o

  • Issue#7464: Blackberry - Unable to uninstall Android Apps and screen flickers while opening Messages (Text Messa

    Hi ,I am Blackberry Leap user and I have typical two problems. Please read below. 1. Recently after an OS update to 10.3.2.2836, I have started facing an issue that I am unable to uninstall android apps. They are not been shown on the home screen but they still show as installed through amazon app store and can access them from there. Also cannot find them in App Manager--Device Monitor--- Storage. 2. When I open Messages (text message) through Blackberry hub or Messages option on the home screen. The screen starts flickering. It flickers for some seconds and then stabilizes. I am facing this issue since I have bought Leap (6 months from now). This seems to be a regular problem with the device and happens always. May please suggest solution to these problems. Cheers!!!Praisy

  • Issue#8147: Getting a new blackberry id - register page doesnt work

    Hi, I am trying to set my wife up wth a balckberry I'd. I have tried about a dozen times to register. I either get;- No error message, just the repeat password field blanked out- A message about insufficient number of characters supplied (no clue as to which field is being referenced here) I have checked the passwords I am entering for length AND rules. When the screen comes back to me the first password field is 13 dots long as opposed to 11 dots when I entered the password. There is no help link for anyone having trouble registering. There is a contact us link but that simply leads to the enterprise software page. Thus although its not BB classic specific I am posting here. Can anyone provide me with any guidance or clue as to what I am doing wrong? Thanks

  • Issue#18652: Blackberry - Swiping up to close an app moves position on list and page

    Was wondering if there is a solution or a fix to remedy this? Every time I close an app by swiping up my position on a webpage or on a chat or contact list or chat list etc scrolls up (i.e. down the page) with the swipe. So everytime I come back to it I have to scroll back to where I was kind of defeating the purpose for having apps on stand by for quick access. If it was couple of lines it could be okay but usually it's pages. A software update to fix this would be great!

  • Issue#19740: Blackberry - Not recieving notification from text on one contact only

    I have read some of the other posts here, and none of the solutions have worked for me.I have deleted Facebook, I have went in and manually deleted every text in the conversation, restarted many times, pulled battery. I can see the texts if I compose a new message, but as soon as it is sent, poof! gone again. No light, no vibration, no nothing. Nothing in the hub. I'm on 10 OS 10.3.2.2474 Normally I really wouldn't care, but the contact i'm not getting texts from is my wife, and she's gotten rather cross with me because of it. She is using a Galaxy Note 4, never had any problems. I think what may have started all this is I accidentally deleted our conversation, and it hasn't worked right since. Can anyone help?

  • Issue#23769: Paypal - Adding text field to donate button/page without separate website

    I am trying to find a way for a donor to specify using a text box or drop down menu what they want their donation to go toward.  I found this page: https://www.paypal.com/webapps/mpp/get-started/donate-button-text-field and was able to duplicate the steps to create a pulldown menu and/or text box, but the problem is that we don't have a separate website, only a paypal account and a mailing list that is managed through mailchimp.  We currently include a donate button in our emails that takes a donor to the standard paypal donation page where they can sign into their account and choose the donation amount.  Is there a way to add the text box and/or pulldown menu to this page?  The text box and pulldown menu don't seem to work in Mailchimp; after the code is added and the email template saved, Mailchimp automatically reformats the code to remove the text box and pulldown menu I created.

  • Issue#49959: Blackberry - Priv battery and heating issue solved for T-Mobile users

    After scouring the internet and opening tickets with Blackberry I can confirm 100% that the battery drainage and heat issue with the Blackberry Priv for T-Mobile users is due to: The My T-Mobile app.  When you go online you read lots of replies and gets lot of people offering advice (turn your display down, turn off your location, turn off sync, etc, etc). I tried them all.Once I disabled and uninstalled the my tmobile app (I actually deleted all t-mobile apps) the problem was solved. It was like I had a new phone. I highly recommend this for T-Mobile users. Good luck!

    I'm fiddling with some public domain books (e.g. collections of writings by John Adams and Thomas Jefferson), and I'm trying to figure out a way to include the original page numbers in the Kindle text so that they can be properly cited for research.My idea is to include the page breaks of the original book and insert the page number in the text at the "top" of each page section. Does this seem reasonable, or would that seem intrusive to readers? On the other hand, is there a better approach? Reply to this post.
