For the "Baptism Ceremony Builder" part of my Ceremony script generator, how would I make a single-line edit box who's label changes depending on which radio button is selected. For example, if the "Infant" or "Child" radio button is selected, the edit box would be named "Child", and if either "Youth" or "Adult" is selected, the same edit box would be named "Participant". This is of course where the customer would put the name of the child/participant being presented in the baptism/christening/dedication/naming ceremony. Same thing goes for the boxes named "Parent 1" (or "Sponsor 1") and "Parent 2" (or "Sponsor 2"). Also, how would I automatically fill in gender appropriate nouns and pronouns in the finished text based on the gender selected (Male or Female)?

That's where signals and slots comes into play. For each control proposing a choice you will have a slot that will modify your UI based on the state/choice of the control that was just modified.

I would appreciate if you could please be so kind as to give me an example of code as to what this will look like. Also, here's a bit of an example of Qt widget code I've put together. Please tell me if this looks right. If there's anything I need to change in my code, please let me know.

QButtonGroup
QRadioButton *button = new QRadioButton ("Bride", this);
QRadioButton *button = new QRadioButton ("Groom", this);
QLineEdit *lineEdit = new QLineEdit ("Spouse 1 Name", this);
QButtonGroup
QRadioButton *button = new QRadioButton ("Bride", this);
QRadioButton *button = new QRadioButton ("Groom", this);
QLineEdit *lineEdit = new QLineEdit ("Spouse 2 Name", this);
QPushButton *button = new QPushButton ("Back", this);
QPushButton *button = new QPushButton ("Next", this);

Do you want to build something like a QWizard ?

I guess you could say that. Then when customers come to the last step, the "Download" button would be like the "Finish" button of an Installation Program if you like. So when customers click the "Download" button, a finished document appears on their screen. Then there could be a "Print" button, and a "Save" button.

There's something that is not exactly clear. Do you want to write an application that people install on there computer to generate these scripts ? Or should they go to some sort of web site ?

It's the former. I want to build an application that people install on their computer.

Ok, then I'd recommend breaking your current design in logical pieces. For example, there's no need to double the number of widget to handle both spouse names. You can create one widget for that part and then have two instances of it in your "main widget".

Two instances of the same widget? I'm confused! Could you please tell me exactly how I could do that? Here's a bit of code, I don't know if this is what you want me to try.

QFormLayout *form = newQFormLayout:
SetWindowTitle(tr("Step 2");
resize(480, 320);
}
QButtonGroup *buttonGroup = new buttonGroup(tr("Spouse 1 Gender")
QRadioButton *radio1 = new QRadioButton ("Bride", this);
QRadioButton *radio2 = new QRadioButton ("Groom", this);
radio1->setChecked(true)
QLineEdit *Spouse1NameEdit = new QLineEdit (this);
QLabel *NameLabel = new QLabel("Spouse 1 Name", this);
NameLabel->setBuddy(Spouse1NameEdit);
QButtonGroup *buttonGroup = new buttonGroup(tr("Spouse 2 Gender")
QRadioButton *radio3 = new QRadioButton ("Bride", this);
QRadioButton *radio4 = new QRadioButton ("Groom", this);
radio4->setChecked(true)
QLineEdit *Spouse2NameEdit = new QLineEdit (this);
QLabel *NameLabel = new QLabel("Spouse 2 Name", this);
NameLabel->setBuddy(Spouse2NameEdit);
QPushButton *button = new QPushButton ("Back", this);
QPushButton *button = new QPushButton ("Next", this);

I also want to find out, how do I put the following text into the beginning of the window when the customer gets to this specific screen.

"The Basics: To begin, enter the first names of the couple, the last name(s) they'll be using after their marriage, and the city/town, then select the state/province, and country in which the wedding will take place."

Same goes for any of the other screens up to the "Finish" screen. The text of the "Finish" screen will say:

"Congratulations! You just built a one-of-a-kind wedding ceremony. Click the "Download" button to read your wedding script in the wizard. Click the "Save" button to save your script in any text format on your computer. Click the "Print" button to send your script to your printer." The kind of ceremony changes, depending on what is selected in the "Welcome" screen. Either a "Wedding Ceremony", a "Baptism Ceremony", or a "Funeral Ceremony".

[SGaist]

You can use a QLabel when you want to show some text.

What I meant is something like:

class SpouseWidget : public QWidget {
    Q_OBJECT
public:
    enum Gender {
        Bride,
        Groom
    }
public:
    SpouseWidget(QWidget *parent = 0);
    QString name() const;
    Gender gender() const;

private:
     QLineEdit *nameLineEdit;
    QButtonGroup *genderButtonGroup;
};

SpouseWidget::SpouseWidget(QWidget *parent):
    QWidget(parent),
    nameLineEdit(new QLineEdit),
    genderButtonGroup(new QButtonGroup(this)

    QRadioButton *brideButton = new QRadioButton (tr("Bride"));
    brideButton->setProperty("gender", SpouseWidget::Bride);
    bride->setChecked(true);
    QRadioButton *groomButton = new QRadioButton (tr("Groom"));
    groomButton->setProperty("gender", SpouseWidget::Groom);

    genderButtonGroup->add(brideButton);
    genderButtonGroup->add(groomButton);
    QHBoxLayout *genderLayout = new QHBoxLayout;
    genderLayout->addWidget(brideButton);
    genderLayout->addWidget(groomButton);

    QFormLayout *layout = new QFormLayout(this);
    layout->addRow(tr("Name"), nameLineEdit);
    layout->addRow(tr("Gender"), genderLayout);
}

QString SpouseWidget::name() const 
{
    return nameLineEdit->text();
}

SpouseWidget::Gender SpouseWidget::gender() const
{
    QAbstractButton *button = genderButtonGroup->checkedButton();
    QVariant genderVariant = button->property("gender");
    return genderVariant.value<SpouseWidget::Gender>()
}

Then in your page you can use a QGroupBox for each spouse with an instance of SpouseWidget inside.

After I compile all my widgets in Notepad++, how would I turn them into an executable program?

[SGaist]

You can use a QLabel to show the text and add it at the bottom of the QFormLayout without specifying a text.

As for your question with Notepad++, maybe using this plugin ?

Could you please explain what you mean when you say, "You can use a QLabel to show the text and add it at the bottom of the QFormLayout without specifying a text."? I'm a bit confused on that one!

I tried installing that plugin, but when I launched Notepad++, a screen popped up with a message telling me that the plugin isn't compatible with the version of Notepad++ I have. Is that because I have a newer version of Notepad++? I'm confused on that one!

[SGaist]

Like shown in my sample widget, you should use layouts in order to place your widgets around in your application. Therefore my suggestion, put your text into a QLabel with setText and then put that label at the appropriate place within the layout.

As for the plugin, it might be out of date regarding the version of Notepad++. If possible, I'd recommend using Qt Creator in order to build your application. It would likely make things easier.

[Annabelle]

How would I be able to use QT Creator to make my project? Would I put the code I've already made in Notepad++ into a new project in Qt Creator? What would I do?

I can't access Qt Creator with my screenreader, JAWS (Job Access With Speech). That's why I'm making the code in Notepad++. I just wish I knew how to make the finished program.

[Annabelle]

I'm still a bit stuck on this Qt Programming Language. Since I can't access Qt Creator with my JAWS screenreader, as it doesn't recognize image-based icons, how else can I create a finished program after compiling the source code in Notepad++? Anybody have any answers for me?

[mrjj]

@Annabelle
So you can compile it already?
Or is it the compiling part that is hard to do ?

Can the JAWS read a command prompt ?
