swipeView setcurrentindex(1) not work

[gfxx]

heme my simple code:

import QtQuick 2.3
import QtQuick.Controls 2.3
import QtQuick.Controls.Material 2.3
import QtDataVisualization 1.3
import QtQuick.LocalStorage 2.0
import QtQuick.Window 2.10

import QtQuick.Extras 1.4
import QtQuick.XmlListModel 2.0
import QtQml.Models 2.1
import QtQuick.Layouts 1.1
import "custom"
import QtCharts 2.2


ApplicationWindow {
    id: mainWindow
    visible: true
    width: 1440
    height: 900
    maximumWidth: 1440
    minimumWidth: 1440
    maximumHeight: 900
    minimumHeight: 900

/* some page style setting code*/

    SwipeView {
        id: swipeView
        anchors.fill: parent
        currentIndex: tabBarMain.currentIndex
        visible: true
        width: 1440
        height: 900
        Layout.fillWidth: true
        Layout.fillHeight: true
        Layout.preferredWidth: 1440
        Layout.preferredHeight: 900
        Layout.minimumWidth: 1440
        Layout.minimumHeight: 900


        //Loader { id: pageLoader }

        Connections {
            target: bcPg1.menuSetSignal
            onPressed: {
                tabBarMain.setCurrentIndex(1)
                swipeView.setCurrentIndex(1)
                tabBarMain.update()
                swipeView.update()
                console.log(tabBarMain.currentIndex)
            }
        }

console and tab is setting in the correct way at every menuSetSignal button onPressed .... but swipe non show the new content.

Way these?
peraphs swipeView and tabbar work ok.

any suggest

Yes for shure a copy and paste error .... but actually i try in these manner:

• convert mybutton into a component (because I have a components that make a similar things and it works) ...
• mycomponent.mybutton.onClicked: tabMytab.currentIndex = 1 NOT WORK AT ALL
• mycomponent.mybutton.onClicked: tabMytab.currentIndex = 1; WORK PERFECTLY
• Connections { ... } way not try if work now ... but I think Shrinidhi Upadhyaya is in right ... but I suspect that ";" would have served in any case

note the ";" ..... :( ...... I'm on ubuntu 18.04, QT5.12 .....

Thanks at All

@gfxx you need to provide some more information.

In the example you posted your swipe view has no content components -> you can't set the index to anything but 0

[Shrinidhi Upadhyaya]

Hi @gfxx , can you be bit more clear on what do you want to achieve onPressed?

This is what i get from the question you have posted.I guess you are changing the index of the SwipeView,but thats not reflecting back!!(Is this your problem),you have already assigned currentIndex: tabBarMain.currentIndex in SwipeView, but still onPressed you are changing the currentIndex value of both TabBar and SwipeView,no need to do that.

        Connections {
            target: bcPg1.menuSetSignal
            onPressed: {
                tabBarMain.setCurrentIndex(1)
                swipeView.setCurrentIndex(1)
                tabBarMain.update()

BcPG1 {
     id: bcPg1 /*  these is the ui.qml page  that contanis the button with id: menuSetSignal */
}
BcPG2 {
     id: bcPg2

BcPG3 {
     id: bcPg3
}
BcPG4 {
     id: bcPg4
}
BcPG5 {
     id: bcPg5
}BcPG6 {
     id: bcPg6
}

}

TabBar { /* tab bar code here */ }

} /* applicationwindows end */

i hope is more clear now ...

        Connections {
            target: bcPg1.menuSetSignal
            onPressed: {
                tabBarMain.setCurrentIndex(1)
                swipeView.setCurrentIndex(1)
                tabBarMain.update()
                swipeView.update()
                console.log(tabBarMain.currentIndex)
            }

these pieces of code in my mind needs to change swipe content view on button.onPressed .... but not work at all .... only change index of tab and swipe, whitout change content page view .....

[Shrinidhi Upadhyaya]

Hi @gfxx ,i dont see much of a problem except few mistakes , which dont impact on your functionality,but have you aliased the menuSetSignal(button) in bcPg1?

For example like this:-

property alias menuSetSignal: button

[gfxx]

@Shrinidhi-Upadhyaya

these my aliased row in bcPg1.ui.qml

property alias menuSetSignal: menuSetSignal  //(the id of button)

but as I see, insert a console.log row as debug ... the index of tab and swipe change .... but the page not swipe ..... swipe only if I use touch swipe on screen or tabBar press ..... if I use button.onPress .... only index change but not the page ....

[Shrinidhi Upadhyaya]

Hi @gfxx , just one thing which i noticed, i think you might have made a mistake while copy pasting it,you need to close Connections { } before BcPG1.

I have not completely copy pasted your code, but have replaced BcPG with an Item, and its working fine for me.

Here is the sample code:-

 SwipeView {
    id: view

    currentIndex: 0
    anchors.fill: parent
    topPadding: 100

    Connections {
        target: firstPage.firstButton

        onClicked: {
            console.log(view.currentIndex)
            view.setCurrentIndex(2)
        }
    }

    Item {
        id: firstPage

        property alias firstButton: firstButton


        Rectangle {
            anchors.fill: parent
            color: "red"
        }

        Button {
            id: firstButton
            height: 100
            width: 100
        }

    }
    Item {
        id: secondPage
        Rectangle {
            anchors.fill: parent
            color: "green"
        }
    }
    Item {
        id: thirdPage
        Rectangle {
            anchors.fill: parent
            color: "yellow"
        }
    }
}

For your code, is the control atleast going inside onPressed signal?
Is your application output showing some warnings or errors?

@gfxx
great that it works for you now, but a ; at the end of line shouldn't/mustn't make a difference in qml

can you check, if that also makes a difference for you in the example @Shrinidhi-Upadhyaya posted?

[gfxx]

@J.Hilk for sure ... (not sure is a correct way to test, because my problem is originally become from bcPg1.menuAdminOutput, when menuAdminOutput is part of bcPg1 .... now menuAdminOutput is part of component bAdmMenu1 .... so ... any how seems parser of qt creator problem).

for fist try these

Connections {
                target: bcPg1.bAdmMenu1.menuAdminOutput
                onClicked: {
                     tabBarMain.currentIndex = 5
                }
            }

NOT WORK

for second these

Connections {
                target: bcPg1.bAdmMenu1.menuAdminOutput
                onClicked: {
                     tabBarMain.currentIndex = 5;
                }
            }

THESE WORK

for third these one again

Connections {
                target: bcPg1.bAdmMenu1.menuAdminOutput
                onClicked: {
                     tabBarMain.currentIndex = 5
                }
            }

And now IT WORKS .....

What is changed from first and third exaple??
