Tool keyboard wont appear when I click on line edit again

[020394]

Hello All, I am new to Qt and I am trying to make a program where when i click the lineedit , a pop up box would show up below . I am able to do that by using

void MainWindow::on_NRIC_cursorPositionChanged(int arg1, int arg2){
popupKeyboard();//Showing the popup keyboard
}

void MainWindow::on_NRIC_cursorPositionChanged(int arg1, int arg2){
popupKeyboard();//Showing the popup keyboard
}

To copy to clipboard, switch view to plain text mode 

But after i close the popup and click on the QLineEdit , The popup does not show at all .

There is another problem , When the text fill is filled with letters,Whenever I press Enter on the popup menu, it would take many clicks to close

QFrame* popupNumpadBed = new QFrame(this, Qt::Tools| Qt::FramelessWindowHint);
     popupNumpadBed->resize(600,500);
     popupNumpadBed->setAttribute( Qt::WA_TranslucentBackground ); 
 QPushButton *BedEnter= new QPushButton(  popupNumpadBed );
BedEnter->setText("Enter");
    BedEnter->setGeometry(450,256.66666, 150, 53.33333);
  BedEnter->setFocus();
  connect(BedEnter, SIGNAL(clicked()), popupNumpadBed, SLOT(hide()));

QFrame* popupNumpadBed = new QFrame(this, Qt::Tools| Qt::FramelessWindowHint);
     popupNumpadBed->resize(600,500);
     popupNumpadBed->setAttribute( Qt::WA_TranslucentBackground ); 
 QPushButton *BedEnter= new QPushButton(  popupNumpadBed );
BedEnter->setText("Enter");
    BedEnter->setGeometry(450,256.66666, 150, 53.33333);
  BedEnter->setFocus();
  connect(BedEnter, SIGNAL(clicked()), popupNumpadBed, SLOT(hide()));

To copy to clipboard, switch view to plain text mode 

Please Help Thank you

cursorPositionChanged() is not triggered when you click anything but when... cursor position changes. If you want to have a virtual keyboard then the proper approach is to implement an input context plugin.

Thanks for the immediate response , Mind if i ask , How do we use the input context plugin method ? I mean how do we use it ?

Qt will take care of using it. You just need to provide it.

I researched about inputcontextplugins but found minimal relevant searches . I tried including QInputContextplugins but to no avail , i cant get it to build . And for the codings of inputcontext pluggin, I am not really sure of how to implement it . Are you able to show me an example so i can read into it ?Thanks

As far as I remember there is an example in the docs on how to implement a simple input context plugin.

Here you go: http://qt-project.org/doc/qt-4.8/tools-inputpanel.html
