Probably and easy +1 for someone out there, but what can I trigger the first time my app start on the first tab ?

Let me explain, when my app start I need to call a function in C++ to execute something, for the other that I can use the onTriggered: {}. The first tab isn't triggered I think it's just selected by default.

Thank you

Hi,

  Into tab there are one method onCreationCompleted() so write code into this function.

Could do something like having some variable equal to 0 and run that function if that variable is 0.  Then as a part of that function change that variable to 1 and use qsettings to save the value of that variable.  Now the next time you open the app that funciton wont run because the variable has been saved to be equal 1.

Yeah that could be an option.

The onCreationComplete never gets fired for me, I have no clue why, maybe because the app starts on that tab... I might be wrong.

onCreationCompleted always works for me as I have similar functions as yours. If you can show your qml source code snippet, it will be quickly checked. thanks

Ok does it have to be on the TabbedPane or the Tab ?

This is my code

// Default empty project template
import bb.cascades 1.0
import bb.data 1.0

TabbedPane {
    Menu.definition: MenuDefinition {
        actions: [
            ActionItem {
                title: "Refresh"
            }
        ]
    }
    showTabsOnActionBar: true
    Tab {
        title: qsTr("Employee")
        imageSource: "asset:///images/Body.png"
        NavigationPane {
            id: employeePane
            Page {
                id: employeeFeed
                ListView {
                    objectName: "employeeView"
                    id: employeeView
                    listItemComponents: [
                        ListItemComponent {
                            type: "item"
                            DetailFeed {
                            }
                        }
                    ]
                    attachedObjects: [
                        ListScrollStateHandler {
                            id: scrollstatehandler
                            
                            onScrollingChanged: {
                                if (atEnd) {
                                    
                                }
                            }
                        }
                    ]
                }
            }
            attachedObjects: [
                ActivityIndicator {
                    objectName: "indicator"
                    verticalAlignment: VerticalAlignment.Center
                    horizontalAlignment: HorizontalAlignment.Center
                    preferredHeight: 200
                    preferredWidth: 200
                }
            ]
        }
        onCreationCompleted: {
            employee.GetDetail("91258")
        }
    }
    Tab {
        title: qsTr("PhoneDirectory")
        imageSource: "asset:///images/Star.png"
        Page {
        }
    }
}

Ok. I see. The onCreationCompleted should be put outside of tab but within TabbedPane.

If you want to load the data for any tab, you can code a javascript function in that tab and call that function in the onCreationCompleted. Say,

TabbedPane { 
    Tab {
        TabABC{
            id: tabxxx
        }
    }
    onCreationCompleted: {
        tabxxx.reloadData();
    }
}
