@ambershark Is it possible we could write Morse code aka keyboard and just tab through the boxes on the installer and select what she needs by pressing keys?

ambershark

@Sunfluxgames You wouldn't really have to write anything.. someone could just run the installer and figure out the exact keypresses she needs to get to the box she wants to uncheck and then list them here. If she's careful she can do it without a screen reader.

Also having a friend help install it would work too.

But again, it's not necessary at all to uncheck qt creator. I usually let it install Qt Creator and I pretty much never use it. I can spare the 200mb or whatever it is on my hard drive though. :)

I've got Qt Creator on my machine, and unfortunately I'm not able to create widgets without a mouse. I wonder, are there any keyboard equivalents to mouse clicks for creating widgets and wizard pages?

ambershark

@Annabelle Absolutely.. I do all my widgets in code. I almost never use the designer to create my forms/widgets.

I.e. if you want a label and text entry field you could do:

QWidget *w = new QWidget();
w->resize(600,400);
QHBoxLayout *box = new QHBoxLayout();
box->addWidget(new QLabel("Name"));
box->addWidget(new QTextEdit());
w->setLayout(box);
w->show();

Do you have any remote access software where you could log on to my computer and show me what you mean? For example, ITeleport? By keyboard shortcuts, I mean something like:
"Create New Widget" (Alt+W)
"Set Layout" (Control+Shift+L)
"Add Widget" (Alt+A)
"Show/Hide" (Control+Shift+H)
"Resize" (Control+R)

@Annabelle You wouldn't need shortcuts to create anything.

In notepad++ you would create a class that can create dynamic widgets with you passing arguments for size and name in the function. All the designer lets us do is make it easier to drag and drop widgets into place while building code for us.

In your case you going to build your application through C++ and .h files.

I'm still a bit confused, because I want to try the Qt Designer, but I seem to be left in the dust as to how I would have access to the command to create, add, delete, and show/hide widgets without keyboard shortcuts. Since I have 0% vision, this is why I use a screenreader and keyboard shortcuts. I wonder if any of the Qt Creator administrators could help with making the program more screenreader friendly. Image-based icons are a screenreader's weak point. text-based icons and menus with detailed descriptions are what is accessible to both sighted and blind individuals alike.

@Annabelle You should really take ambershark's advice. Code all your widgets in notepad++ and use the command line to complie your project into a .exe

Then have someone with vision look over your project to make sure it looks the way you think. Even with the basics understanding of C++ your project is very simple to do.

I tried the code:

qmake ceremonyscriptgenerator.pro
make

but it gives me the error message that "qmake is not a valid internal or external command or operable program". This is even after Qt Creator and all of its components are completely installed on my machine. Perhaps there's something I'm doing wrong? Maybe I could ask my friend, Markus Johnson (yes, that's "Markus" with a K, not a C), if he could try to set up some mouse movement scripts for Qt Designer with Axife Mouse Recorder (http://www.axife.com).

mrjj

Hi
It cannot find qmake. you must use full path to it
like
C:\Qt\5.9.1\msvc2015_64\bin\qmake.exe
but yours will something with mingw and not msvc2015_64

Allanis

Ok, so you have installed Qt again in full I assume. And you are back to the very same error you had before when you used:

qmake ceremonyscriptgenerator.pro
make

But remember, you already got an answer to solve this by @sierdzio :

@sierdzio said in Qt Programming Language:

Alternatively, with your current command line, you can point it directly to where qmake is located, like this:
c:\path\to\where\qt\is\bin\qmake.exe file.pro
Oh, right. Possibly you need to type in "qmake.exe" instead of just "qmake" on Windows.

Allanis

Oh @mrjj got there first. :P

ambershark

@Annabelle There's very little chance of you being able to use the designer without sight. You absolutely have to use a mouse.

However you do not need the designer to make user interfaces. You just code them like I showed you. No designer required, all can be done with your editor of choice, i.e. Notepad++.

So really you just need to learn Qt by reading documentation and or books with your reader. Then you can literally just write the code, no vision required other than having someone check your layouts and such to make sure things looks good.

@SGaist said in Qt Programming Language:

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.

So for example, connecting a push button to a signal would look like:

    signalMapper = new 
QSignalMapper
(this);
    signalMapper->setMapping(BackButton, 
QString
("Step 1.txt"));
    signalMapper->setMapping(NextButton, 
QString
("Step 3.txt"));
    signalMapper->setMapping(CancelButton, 
QString
("Cancel"));

    connect(BackButton, &
QPushButton::
clicked,
        signalMapper, &
QSignalMapper::
map);
    connect(NextButton, &
QPushButton::
clicked,
        signalMapper, &
QSignalMapper::
map);
    connect(CancelButton, &
QPushButton::
clicked,
        signalMapper, &
QSignalMapper::
map);

Specifically, when I talk about filling in gender-specific words in the finished text, for example, when "Female" is selected, the appropriate gender-specific pronouns (she, her, hers, herself) are automatically printed in the place which would say "Gender pronoun" if neither radio button is selected. Same goes for gender nouns (man, woman, boy, girl).

@SGaist said in Qt Programming Language:

With C++ the QComboBox widget or with Qt Quick the ComboBox QML type.

Does the documentation on the QComboBox widget specifically have instructions on how to add items to a combo box? I've searched there, and it only tells me properties inherited from other QWidgets, along with a detailed description of the QComboBox.

ambershark

@Annabelle You're looing for addItem and addItems.

@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.

One thing I'm stumped on is the use of "public" and "private". Are those parameters meant to share some of the widgets with the general population, but hide any widgets with what would otherwise be regarded as personal information?

Annabelle

I wonder if I can use QAccessible widgets instead. What would those look like? For example, would I write something like:
QAccessibleMenu *languageMenu;
I wonder if they have QAccessible versions of QRadioButton, QComboBox, and QListBox?
