TabbedPane - sending of property value when the new tab is selected

Hi just designed tutorial, I have two tabs: vegetables and fruits.

The two tabs will use the same qml file (inside is a unique list) but of course will use different DataModel.

So, I set up a property for the DataModel source and place it when the current tab changes,

Here's my simplified code:

//main.qml
TabbedPane{
    Tab{
        title: "Veggie"
        MyNextPage{}
    }
    Tab{
        title: "Fruit"
        MyNextPage{}
    }
    //Looks like here's the problem
    onActiveTabChanged:{
        var page = myComponentDefinition.createObject();
        if(activeTab.title == "Veggie")
            page.dataModelSource = "models/veggie.xml";
        else{
            page.dataModelSource = "models/fruit.xml";
        }
    }

    attachedObjects: [
        ComponentDefinition {
            id: myComponentDefinition
            source: "MyNextPage.qml"
        }
    ]
}

//MyNextPage.qml
Page{
    property alias dataModelSource: myListView.dataModel.source
    Content{
        ListView{
            id: myListView
            layout: ...
            dataModel: XmlDataModel{
                source: "models/veggie.xml"
            }
        }
    }
}

But he blocks my request. I don't know about works like that of property. Anyway the solution or alternative to send a value to another page?

Thanks before

It's easier if you do not attach the page, as follows:

//MyNextPage.qml
Page{
    property alias dataSource: dataModel.source
    Content{
        ListView{
            id: myListView
            layout: ...
            dataModel: XmlDataModel{
                id : dataModel
                //source: "models/veggie.xml"
            }
        }
    }
}

and then in your tabbedpane

TabbedPane{
    Tab{
        title: "Veggie"
        MyNextPage{
dataSource : "models/veggie.xml";
}
    }
    Tab{
        title: "Fruit"
        MyNextPage{
    dataSource : "models/fruit.xml";
}
    }
}

  • Firefox reduced when the new tab is open

    When I open some links that open in a new tab (for example my bank statement has an option 'printable version' and when I click on this link and it will open in a new tab) firefox suddenly minimizes and becomes much smaller.

  • Firefox keeps looking for updates when the new tab open.

    I'm under the latest version of Firefox (40.0.3) with adblocker more like my single addon. However whenever I try to open a new tab it take ages to open because Firefox is constantly looking for an update. It takes 2-3 minutes each time. Did you try refreshing Firefox, uninstall and reinstall without success. My system is 8.1 Win on a Lenovo PC i7. Everything worked well until the last FF update. I have no problem with the same version installed on my laptop.

  • Is it possible to have the new tab page is displayed by default when you start Firefox?

    Firefox may be set to view the new tab page when the browser is started? In Options > general, the only choices under "Startup of Firefox" is the home page, a blank tab or restore previous session.

    Alternatively, the new tab page is adjustable as home page?

    The value 'When Firefox starts' to 'Show my home page' and 'Home Page' "subject: newtab".

  • How can I get the default for the new tab page when there is no improved/classic/empty choises when I click on the gear icon.

    When I open a new tab, I used to get a page which had tiles for some of the sites I visit often. Now I get the Bing search page. The help of instructions say I can change the default new tab page by clicking on the gear on a new improved, classic, or blank page icon in a drop-down list. When I click on the train, I don't get this list of options. Instead, a settings page appears, allowing me to make various changes, but improved, classic or white new tab page choices aren't there. What should I do?

    To modify the new page tab, please follow these steps:

    1. Go to about:config in Firefox
    2. Locate the browser.newtab.url string
    3. Set the value of this string on the URL of your page to the desired tab

    This should change the new tab page.

    Notes:

    • Set the about:newtab to get the page of the new classic tab
    • Set the about:home to get the default home page
    • Set the about:blank to get the blank page

    Start Firefox in Safe Mode to check if one of the extensions (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem (switch to the DEFAULT theme: Firefox/tools > Modules > appearance).

    • Do NOT click on the reset button on the startup window Mode without failure.

    You can use the SearchReset extension to reset preferences to default values.

    Note that the SearchReset extension runs only once and then uninstalls automatically, so it will not appear on the page "> Firefox Add-ons" (topic: addons).

  • Is it possible that when the new record is inserted in a table then this empty inserted record is automatically displayed without scrolling?

    Mr President.

    Is it possible that when the new record is inserted in a table then this empty inserted record is automatically displayed without scrolling?

    Because I change the size property of the table 5 range and my new record is inserted at no 10.

    When I click the addRecord button the new parallel line does not appear, do scroll down to see it.

    I want that we don't have to scroll down.

    The line is displayed automatically.

    Concerning

    If you just need the newly created line to be visible,

    You can simply set contentDelivery = 'immediate' and displayRow = "selected".

  • How to make the homepage to appear when opening new tab

    Under Firefox 40.x whenever I opened a new tab, my home page appeared. When I upgraded to 41.0, opening a new tab displays the suggested sites. How do I have my home page appear whenever I open a new tab?

    41 of Firefox is no longer uses the browser.newtab.url setting in about: config because he was constantly attacked by malware. From 41 of Firefox, you need an add-on to change the new tab page.

    Here are a few options (I'm learning more all the time):

    • If you are already using Classic theme restaurant: There is an option somewhere (!) in his dialogues of the parameters to select another page in the new tab.

    Setting up substitute again tab

    After installing this extension, you must use the Options page to set the new desired tab page (instead of use subject: config).

    Open the page modules using either:

    • CTRL + SHIFT + a (Mac: Cmd + shift + a)
    • "3-bar" menu button (or tools) > Add-ons

    In the left column, click Extensions. Then on the side right, find the new tab override and click the Options button. (See first screenshot attached).

    Depending on the size of your screen, you may need to scroll down to enter the address in the form. (See second screenshot attached). For example:

    • (Default) page thumbnails = > subject: newtab
    • Blank tab = > subject: empty
    • Built-in Firefox homepage = > topic: welcome
    • Any other page = > full URL of the page

    Then tab or click this form field and you can test using Ctrl + t.

    Success?

    Once you have set it as you wish, you can close the Add-ons page (or use the back button to return to the list of Extensions of this Options page).

  • Yahoo appears when I press the new tab now and continues to do so even if I change it back

    I tried the subject: config and the removal of Yahoo / change in about: newtab - it works, but in about 30 minutes, it is for Yahoo. I checked add-ins and extensions, and the only thing I'm running is Norton. I even tried to go back to the original version of Firefox, in case Yahoo has uploaded a new modified version, and that seems to work, yesterday. But today, when I clicked on the new tab - Yahoo back again. Nothing to do, it seems made a difference - it's worse than a virus, as it seems to keep regenerating itself. Can anyone help please?

    I have "think THAT"I could find a resolution. I included here for info to others.
    Went to the control panel in Windows
    Choose to uninstall a program
    Clicking the column installed on everything in date order.
    Noticed that at the same time I installed another piece of software a 2nd piece has been installed without my permission. It was called Hub a lot of results.
    Selected many results Hub and uninstalled.
    To do this, I noticed that it closed Firefox.
    After uninstalling, I restarted the PC, just in case he left something in memory
    Then once it restarts again, I uninstalled Firefox (tbh, I probably didn't need to do that, but wasn't any risk)
    Rebooted again (probably no need to do)
    Once the PC itself started, I installed a version of Firefox.

    Now, fingers crossed, it worked. If it has, I'll come back here tomorrow and this will mark as resolved.
