Why can't I access object inside the ListItemComponent.onCreationCompleted C++... ?
Hello world
My application has a HTTP connection to retrieve the XML stream and insert data to the ListView using DataSource and DataModel, and I want to hear at each of its ListView ListItem is created and completely to use a ListItemData for my c++ object. So I write my code like this
In main.cpp
int main (int argc, char * argv)
{
App app (argc, argv);
new MyApp (&app);)
returnApplication::exec();
}
In MyApp.cpp
MyApp::MyApp (bb::cascades:Application * app): //constructor
{QObject (app)}
QmlDocument * qml = QmlDocument::create("asset:///main.qml").parent(this);
QML-> setContextProperty ("app", this);
AbstractPane * stream = qml-> createRootObject
App-> setScene (NCA); } void MyApp::doMyFunction (const QString & someData) {} qDebug()< "yes!!=""> } In main.qml {Of container {To ListView dataModel: myDataModel listItemComponents:] {ListItemComponent} type: 'point '. {Of container onCreationCompleted: {} Console.log ("-LISTITEM ONCREATION COMPLETED"); app.doMyFunction (ListItemData.someData); //< but="" console="" print="" about="" "can't="" find="" variable="" "app"=""> } } } ] } //end listview } //end container onCreationCompleted: {} myDataSource.load (); } attachedObjects:] {GroupDataModel} ID: myDataModel }, DataSource {} ID: myDataSource Source: "some URLs to get RSS... blah blah." type: DataSource.Xml onDataLoaded: {} myDataModel.clear (); myDataModel.insertList (data); } ] } I try to run mycode. But a console is printed on "can't find variable: app". " How can I solve this problem? Thanks for any suggestions. Its because the listitem is not in the same document as the Page tree really, he lives with ListView and does not have direct access to the elements of the Page. What you can do is create a javascript function in the ListView, and then the listitemcomponent facing, which in turn can relay to your environment variable "app." int listitemcomponent add id: itemContainer your container can in the listview: function somefunctiondefinedinlistview (data) {} Tags: BlackBerry Developers Why can I not move objects to the bottom of the timeline in the video? Hello Why can't I move the new object I inserted (this is a PNG image) all down the timeline just above the video/audio? That's where I need? I edit the video with stripes, zooms and slices. I really hope that I can move it to the bottom of the timeline. Thank you This a cpvc of the project, right? Several chronologies are open when necessary, and it is indeed not possible (as in cptx projects) to change the stacking order. However, this could be a workaround: move the timeline you want to down horizontally until you have an empty space: you can then move it to the bottom. You'll go up the other deadlines in the location where you want to have this object at the bottom... Then, you will have to move again. Very heavy, I think it's much easier to think before you add objects and add them in the right order. CPVC-feature did not get much attention, after it was introduced, it is probably not that popular? I use a Macbook with the font book. I am not able to access all the fonts in the font by Illustrator book, which has never been a problem before the creative cloud. I buy fonts - they are some fonts free janky. They are .otf and there is no problem with the installation. Hi Eileen,. Fonts are not displayed to the top? Do you see fonts show in other applications? Try resetting the Illustrator preferences first. You have another like suitcase font management software? Are able to install other fonts and ask them to show you? Can you give us to download it for free. I can test on my end http://helpx.Adobe.com/Illustrator/KB/preference-file-location-Illustrator.html Thank you Scott I can't resize any object inside a tab control and control of the tab itself Hi all Since this morning I noticed that I can't always resize the object placed inside a tab control or the control tab itself. I have a few objects (controls, indicators, etc.) outside of the tab control, and they are resizable (I can see the dark blue squares and I am able to adjust the object); Instead, any object inside the tab control is still not resizable (when I select the dark blue boxes are not visible and I can't access the properties of the object by clicking with the right button of the mouse over it). If I have access to the properties of the object to the block diagram, the appearance of her-> frame size is gray and I can't change the size fields. It seems that something was changed when I try to adjust the minimum window size and appearance of windows in the proposals of VI, but I restore the previous values... How can I solve this problem? Sure, tab control is not locked. If the tab control is locked that resize is not possible Lucast85 wrote: Hi all Since this morning I noticed that I can't always resize the object placed inside a tab control or the control tab itself.

[Q] can Vision track multiple objects in the same area - objects that might cross? Hello Sorry for this long title, but this is my question. Can Vision track multiple objects in the same area - objects that could cross? Because I'm able to do, extraction of XY, but it seems that "IMAQ County objects ' don't follow framework after but framework opposed, but extract the coordinates XY always in the same way, as for example from top and whenever he sees an object, it retrieves the XY, but if the objects pass through (then it will extract XY without worrying that the objects was the earlier but just based on"scan from top to bottom"). That's why I open this topic in the forum of Vision no part: http://forums.ni.com/t5/LabVIEW/Sort-XY-by-closest/td-p/2440428 Thank you Sébastien Thank you for your response.
