problem setFocus() in ui object

Dante Leoncini

Hi , I'm trying to focus on an object in a " ui" from another " ui" but I'm not making. Use qt 4.8.

pressed a button to focus on another button in the same ui with this code and works

Touchpad::Touchpad(QWidget *parent)
    : QWidget(parent)
{
	ui.setupUi(this);

       connect(ui.Enfocar, SIGNAL(clicked()), ui.Cerrar,  SLOT(setFocus()));
}

try to focus to a widget from another ui with this code but not work

Touchpad::Touchpad(QWidget *parent)
    : QWidget(parent)
{
	ui.setupUi(this);
connect(ui.Enfocar, SIGNAL(clicked()), MainWindow::ui.nameCombo,  SLOT(setFocus()));
}

the object you want to focus is a QComboBox , objetname " NameCombo ". this in a "ui " file.
that belongs to "MainWindow"

Hi,

You can't access a private members of another class that way. If you really want to call setFocus in MainWindow's GUI, add a signal to Touchpad that will tell that you clicked ui.Enfocar and in MainWindow, add a slot that will call setFocus on NameCombo.

Press the button and nothing happens. if not misunderstood

in touchpad.h add:

signals:
    void hacer_foco();

//and

private slots:
    void Enfocando();

in touchpad.cpp add:

//within Touchpad::Touchpad(QWidget *parent)

connect(ui.Enfocar, SIGNAL(clicked()), this, SLOT(Enfocando()));

//out of Touchpad::Touchpad(QWidget *parent)

void Touchpad::Enfocando()
{
emit hacer_foco();
}

in mainwindows.h add

public slots:
    void hacer_foco();

and finally in mainwindow.cpp add

void Pantalla::hacer_foco()
{
ui.nameCombo->setFocus();
}

I try to do:

Are you trying to implement a virtual keyboard ?

Dante Leoncini

Yes, but that's for later. I have a bluetooth keyboard. so I leave it to the end.

SGaist

Meaning that you are putting that feature on hold ?

Dante Leoncini

@SGaist Yup. I will add in the future
