the virtualkeyboard does not add to my project.

sierdzio

Which platform? The virtual keyboard plugin is not available on iOS and Android yet., it is only there for embedded systems.

MhM93

sorry to forget said, I used the embedded device. friendly arm.
It does not show keyboard.
I use Qt5.9.1.
my device is nanopc t3 from friendlyarm.
also in main.qml i write :

import QtQuick 2.7
import QtQuick.Controls 2.0
import QtQuick.Layouts 1.3
import QtQuick.VirtualKeyboard 2.1

ApplicationWindow {
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello World")
    TextInput {
        id: textInput;
        width: 200
        height: 200
        anchors.fill:parent
        color: "#000000";
        text: "salam" // black

        // http://doc.qt.io/qt-5/qinputmethod.html#properties
        focus: Qt.inputMethod.visible;

        verticalAlignment: TextInput.AlignVCenter;
    }


}

I think you may need to implement the InputPanel for it to work. See the docs https://doc.qt.io/qt-5/qtvirtualkeyboard-deployment-guide.html

Also, please check your console output - are there any plugin loading errors or warnings?

You can try checking if QT_DEBUG_PLUGINS will help: https://doc.qt.io/qt-5/deployment-plugins.html#debugging-plugins

my problem is basic example that belongs to qt example is work perfectly on my device, but I copy that code, that I think they are essetional, but my prj not worked.
I want to know is there any thing I missed?

I don't know, I can only keep guessing unfortunately.

Is your build static? Otherwise your .pro won't include the virtual keyboard.

BTW. As paying customer you have access to Qt support, so you can also ping Qt Company about this.

MhM93

I use open source qt version.
I just know I should add static link in .pro file and add
qputenv("QT_IM_MODULE", QByteArray("qtvirtualkeyboard"));
to main.cpp file to use the virtual keyboard. but my virtual keyboard does not fire.

MhM93

just set the input method.

InputPanel{
        id:inputpanel
        visible:active
        y:active?parent.height - inputpanel.height : parent.height
        anchors.left: parent.left
        anchors.right: parent.right

    }
    TextInput{
        id:input
        inputMethodHints: Qt.ImhDigitsOnly
        focus: Qt.inputMethod.visible;
        text: "123211"

    }
    TextInput{
        id:input2
        anchors.top:input.bottom
        inputMethodHints: Qt.ImhLowercaseOnly
        focus: Qt.inputMethod.visible;
        text: "123211"

    }

Then all your code (of your app) should be licensed under GPLv3, I hope you are aware of that.

Are you sure QtVirtualKeyboard plugin has been built? Do you see it in your Qt installation? Do you deploy it as mentioned in https://doc.qt.io/qt-5/qtvirtualkeyboard-deployment-guide.html ? Your .pro file does not contain any deployment code.

yes, but do you build in static mode? Do you set CONFIG+=static anywhere in your .pro or when calling qmake? Because if not, then this code will never be called:

static {
    QT += svg
    QTPLUGIN += qtvirtualkeyboardplugin
}

MhM93

@sierdzio when I remove static flag it works too.
means just this:

QT += svg
    QTPLUGIN += qtvirtualkeyboardplugin

so there is no problem with this licence. Is it true?

So the problem is solved?

I'm not a lawyer, can't answer that with certainty. Since the virtual keyboard is licensed under GPL, and it is being linked into your project, I think you are still required tolicense your code under GPL.
