Qt Programming Language

@SGaist said in Qt Programming Language:

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?

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 ?

[Annabelle]

I'm still a bit confused on how to make the finished program. I can't access the Qt Creator, since my screenreader, or any screenreaders, for that matter, won't recognize image-based icons. Is there a way for someone blind like me to create a finished program such as the app I'm putting together, after compiling the source code in Notepad++?

[sierdzio]

Do you have the code ready, with a .pro file (it is a project definition file that Qt uses to compile applications)? If yes, then you can compile your project from the command line. Open cmd.exe (I guess you are on Windows operating system) and type:

qmake yourprojectname.pro
make

That should be enough, assuming your environment is prepared (qmake and compiler are both set up in PATH system variable).

As a side note, as far as I know there is an accessibility team working at Qt Company, I'm sure they will be happy to hear how both Qt and Qt Creator can be improved to help blind people. You can try reaching them at qt-creator@qt-project.org. You can also subscribe to Qt Creator mailing list here: http://lists.qt-project.org/mailman/listinfo/qt-creator.

I can make the source code, it's the compiling the finished program part that's hard. Yes, JAWS can read a Command Prompt. What do I do in there?

[Allanis]

Hi, you will need to create a .pro file which gives instructions on how to build your application. http://doc.qt.io/qt-4.8/qmake-project-files.html

Once you have have this. you can do as instructed by @sierdzio in CMD.

[Allanis]

@Annabelle Sorry, I was at work when I made my initial response to this thread. A more elaborate answer for you follows as I take it you are beginning in Qt and it may be difficult for you to look up resources.

Given the scope of your project I think it will suffice to use a simple Qmake project file such as:

myapp.pro

TEMPLATE = app

QT += widgets

SOURCES += main.cpp \
    MainWindow.cpp \
    SpouseWidget.cpp

HEADERS += \
    MainWindow.h \
    SpouswWidget.h

OTHER_FILES += \
    anyotherfile.png

You may need to make changes to this in order to fit the needs of your project, but this should be a good enough example for you.

Once you have this in place, you can open up your favorite Command Line Interface (eg. cmd.exe for Windows).

Type:

qmake myapp.pro
make

Your compiler will generate a binary file for your application at this point.

I hope this helps,
Have fun.

Another thing I'd like to do is make icons for the push buttons, radio buttons, combo boxes, and checkboxes. I'd like to find out, is it OK for me to use unicode symbols as icons? For example:
In the welcome screen, there are the following Radio Buttons
⚭ (Wedding Ceremony Radio Button)
~⛲ (Baptism Ceremony Radio Button)
⛼ (Funeral Ceremony Radio Button)
For the Spouse Genders, there should be the following Icons:
👰 (Bride Radio Button)
🤵 (Groom Radio Button)
For the Baptism Person Types, there should be the following Icons:
👦👶👧 (Infant Radio Button)
👦👧 (Child Radio Button)
👦👨👧👩 (Youth Radio Button)
👨👴👩👵 (Adult Radio Button)
For the Funeral Ceremony Types, there should be the following icons:
⚰ (Funeral Radio Button)
⚱ (Memorial Service Radio Button)
Note that some of the icons are composed of two or more unicode characters put together, as I couldn't find separate unicode symbols to represent them.

[Allanis]

You should be able to use QString::fromUtf8() for this: http://doc.qt.io/qt-5/qstring.html#fromUtf8

@Allanis said in Qt Programming Language:

Could you please be so kind as to give me an example of what one of my icons would look like with the QString::fromUtf8() code? For example: 👦👶👧

[Allanis]

Sure. I'm not sure exactly what you mean. Do you want an image or a code example? either way I whipped up a quick example to demonstrate what it would look like. Here's an image.

Given that your first post mentioned you where visually impaired, I think I may have misunderstood your meaning, so here's an example in code:

  QRadioButton* rb = new QRadioButton();
  QString str = QString::fromUtf8("<Utf-8 code> Button Name");
  rb->setText(str);

Where <Utf-8 code> = the character you wish to display.
Pretty sure there is a nicer way to do it. But I'm off to bed. That should get you started though.

So are you thinking I should write something like:
QRadioButton* rb = new QRadioButton();
QString str = QString::fromUtf8("<👰> Button Name");
rb->setText(str);
And for "Button Name", would it be something like:
QRadioButton* rb = new QRadioButton();
QString str = QString::fromUtf8("<👰> Bride");
rb->setText(str);
Something along those lines?

[Allanis]

Yeah that will work. But remove the <> from around your unicode character. I only placed them their as placeholder. It will work by placing the unicode character in your source file as you have done, but I would recommend finding the value for it instead. I'm replying from my phone so I can't look ot up for you.
