Show keyboard when QTextEdit is activated

[ivanicy]

Hello!

I am developing a tablet application with Windows 10. I have some data inputs and I want to show the keyboard when I push on them. I don't know why, but in some cases, the keyboard appears automatically and in other cases it doesn't appear.

Do you know how to fix it?

Thank you very much!!

Are you using QtWidgets or QtQuick (QML)?

@VRonin I am using QtWidgets

Hi @ivanicy

Which Qt version are you using?

Are you using the Qt Virtual Keyboard?
How are you displaying your keyboard , can you share a sample code?

@mostefa No, I want to show the system keyboard ( I am running the program in a tablet). I have observed that if the echoMode property of the QLineEdit is "password" when I push on it, the windows keyboard appears automatically, but, if the echoMode property is any other, the keyboard doesn't appear.

Ok ,

I don't know if what i will describe will help you , cause in my case i was not using android , i was a virtual keyboard on imx6 embedded card,

The Qt Doc speak about RequestSoftwareInputPanel

This enum describes under what circumstances a software input panel will be requested by input capable widgets.

to know how to use this enum , you can get inspired from this post:

I hope this can help you!

I have just another question :

Have you the problem with all input widgets , (such as : QLineEdit, QTextEdit..) or just with QTextEdit?

@mostefa Thank you for your answer. I am running the app in a Windows tablet. The problem is with all input widgets. Only when this widgets are password echoMode, it works correctly. I will try your solution, and I hope it to work!

@ivanicy ,

Whenever if you click inside the textedit, application will show the on screen keyboard.
Try this code.

MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
connect(ui->textEdit,SIGNAL(selectionChanged()),this,SLOT(SLT_TextEditActivated()));
connect(this,SIGNAL(SGN_ShowKeyboard()),this,SLOT(SLT_ShowKeyboard()));

}
void MainWindow::SLT_ShowKeyboard(){
qDebug()<<"Showing Keyboard"<<endl;
QProcess *myProcess = new QProcess(this);
myProcess->startDetached("C:\Windows\System32\osk.exe");
}

void MainWindow::SLT_TextEditActivated(){
qDebug()<<"TextEdit Activated"<<endl;
emit SGN_ShowKeyboard();
}

@Vinod-Kuntoji It could be a temporal solution. This solution shows this keyboard:

but, it shows the administrator window before open it. I want to show the pop-up keyboard:

that is shown automatically. This keyboard only appears when the QLineEdit has "password" echoMode.
