Slider movement

Sushma_MP

Hi,

I have a slider functionality in Qt, i need to update the movement of slider in QML by reading the value from Qt functionality.

p3c0

@Sushma_MP Set the value ?

Sushma_MP

yes i want to set the value to the slider developed in QML.
how to do that...?

mrjj

@Sushma_MP
Hi you should show your code with the c++ signal
and the QML where you want to get the slider signal.

assign a value to value using id

Hi,

Below code is to set and update the position in cpp in which am emitting signal with slider position.

//SelectedSong.cpp

//setPosition method

void SelectedSong::setPosition(int position)
{
    if (qAbs(mediaplayer->position() - position) > 99)
    {
        mediaplayer->setPosition(position);

      emit signaltogetsliderposition(position);
    }
}

//update position method
void SelectedSong::updatePosition(qint64 position)
{
    positionSlider->setValue(position);
    QTime duration(0, position / 60000, qRound((position % 60000) / 1000.0));
}

I catched that signal in QML as below:

 Selectedsong{
        id:mysong
        onSignaltogetsliderposition:
        {
            console.log("signal catched...")
        }
    }

Am creating slider in QML as fallows:

// Creation of Slider in QML

 Slider {
                id: control
                value: 0.0

                background: Rectangle {
                    x: control.leftPadding
                    y: control.topPadding + control.availableHeight / 2 - height / 2
                    implicitWidth: music_main_rect.width/2
                    implicitHeight: music_main_rect.height/50
                    width: control.availableWidth
                    height: implicitHeight
                    radius: 4
                    //color: "#474647"
                    color: "#bdbebf"


                    Rectangle {
                        width: control.visualPosition * parent.width
                        height: parent.height
                        //color: "#bdbebf"
                        color: "#5da9e9"
                        radius: 4
                    }
                }

                handle: Rectangle {
                    x: control.leftPadding + control.visualPosition * (control.availableWidth - width)
                    y: control.topPadding + control.availableHeight / 2 - height / 2
                    implicitWidth: 26
                    implicitHeight: 26
                    radius: 13
                    color: control.pressed ? "#f0f0f0" : "#f6f6f6"
                    border.color: "#bdbebf"
                }
            }

Problem is i am not understanding how can i set that sliderposition from cpp file to this value present in slider.

@Sushma_MP Can't you access Slider using its id in onSignaltogetsliderposition ?
