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?

@mrjj
You're right that Qt Creator doesn't work with screenreaders. I sure wish I could find something that does work, aside from just creating the file in a plain text editor like Notepad. And you're also right that screenshots would be useless for me, as I can't see anything at all, not even lights and colors.

Annabelle

So as an example, if I want the gender-appropriate wordings to be printed in the finished script, triggered by the "Groom", "Bride", "Male" or "Female" radio buttons being checked, how would I do this? For example, the default text that appears in the Wedding Ceremony script if neither gender radio button has been checked, and if no names have been given, would be something like:

(Name), will you have this person to be your lawfully wedded spouse, to have and to hold from this day forward? Will you love him/her, comfort him/her, honor and keep him/her in sickness and in health? And, forsaking all others, be faithful only to him/her, so long as you both shall live?

(Name) would of course be replaced by the names of the individuals being married, which the customer will type in the edit boxes named "Spouse 1 Name" and "Spouse 2 Name". If the Bride radio button is checked, "person" would be replaced with "woman", and "spouse" would be replaced with "wife" and "him/her" (or would it be easier to put "them" for unspecified gender) would be replaced with "her". When the Groom radio button is checked, "Person" would be replaced with "Man" and "Spouse" would be replaced with "Husband", and "him/her" would be replaced with "him". Or, I could put an option where "husband" and "wife" could be customized to say "life partner", "lover", or whatever the couple chooses to call each other in an edit box. Maybe that edit box can be triggered by a radio button that says "custom Title". Also, I have a checkbox named "SameLastName". If checked, an edit box appears that is called "Last Name For Couple". However, I want to make it so that if the checkbox is unchecked, the "Last Name For Couple" edit box is hidden, and instead, two edit boxes appear that are called "Last Name for Spouse 1" and "Last Name for Spouse 2". How would I code these parameters?

@ambershark said in Qt Programming Language:

@Annabelle I can't help you with the chm part, but if you need help compiling I can help you figure out both qmake and cmake. Cmake being my preferred method of building Qt projects.

I build everything command line and rarely use IDEs. That sounds exactly what you're looking for if you are using notepad++ and just need a command line build.

Is Cmake built in to the Command Prompt in Windows 7? Or would I have to install it from a download at an external source? I also ask this about Qmake. The reason why I ask is because I tried typing the Qmake code that someone posted earlier on the forum, and it said something along the lines of, "Qmake is not an operable program or a valid internal command". What's up with that, I wonder?

No, cmake is not installed on Windows by default. You can get it from here: https://cmake.org/files/v3.12/cmake-3.12.1-win64-x64.msi I see some warning about this installer on cmake website (https://cmake.org/download/), but I'm not a regular Windows user so I don't know whether this warning can be ignored or not.

About qmake: when you install Qt, it will not update the system PATH variable - so qmake won't be available in standard command prompt. There are 2 ways around it:

open Qt command prompt (it will be installed to Qt directory in start menu)
or type full path to qmake in normal Windows command prompt (it will be something like c:\Qt\5.11.1\mingw53_32\bin\qmake.exe)

Does that warning refer to the program possibly not having passed Window logo testing? I've had that warning on several programs, and even hardware drivers. Do I just press enter on "Continue Anyway"?

Perhaps, I don't know to be honest. It is a package from official cmake website, though, so I would assume it's safe to click "continue anyway".

I know my machine with Windows 7 64 Bit comes with Visual C 2012. Will that be the program that works with Cmake in the command line? I'm confused on this one.

cmake is a build system. It uses compilers (like Visual c++ compiler) to compile your code. So in that regard it works very similar to qmake - it parses a project file, produces a Makefile, and then you can run make to compile the project.

Which widget would I use to display the text of a ceremony script? I'm confused as to whether I want a QTextEdit, or some other widget. What I specifically want to do is display the text across the entire screen in Step 20. Is there such a widget as a QPanel? Here's an example of what I mean when I say, completed text in Step 20. This is in HTML. This is displayed after one presses the "Finish" button when creating a ceremony.

I notice that your HTML document contains lots of "div" classes. This suggests to me that it relies on an external CSS stylesheet to visually format the script contents.

QTextEdit and QTextBrowser can display simple HTML and CSS, but they don't support all modern HTML and CSS.

A full-fledged HTML and CSS renderer is QWebEngineView, in the Qt WebEngine Widgets module. Give it a try. Note: You might need to re-run your installer and select the installer; I can't remember if it's installed by default. Also, on Windows, Qt WebEngine requires a recent Visual Studio compiler because it uses Chromium internally. Chromium doesn't support the MinGW compiler.

The HTML was an example. I wonder if there is an equivalent to Div classes in Qt. Like something for plain text?

@Annabelle said in Qt Programming Language:

Can you give more details on your requirements? Who will use the display to view ceremony script?

"Plain text" refers to the words only, without any visual formatting such as size, position, font, colour, etc.

Nowadays, CSS files contain the visual formatting rules while HTML files contain the actual text content. Div classes in HTML files link a block of text content to the CSS rules.

For example, your sample has many blocks of text tagged with the "panel-heading" div class, and many more blocks of text tagged with the "panel-body" div class. I'm guessing that the corresponding CSS file contains rules that format all "panel-heading" text in large, bold font; similarly, the CSS rules will probably format all "panel-body" text in much smaller font.

QTextEdit does not support external CSS files, but it does support some "inline" CSS (which means the CSS rules are embedded in the HTML document itself). You can find out what's supported at http://doc.qt.io/qt-5/richtext-html-subset.html.

If you only want to display plain, unformatted text, then you can use QTextEdit or QPlainTextEdit.

It's the latter, and the customer can customize what style they want to view it in. For example, if sighted customers want to customize the format of the text, they can adjust the font, size and color to their likings. As for blind customers, I'm not sure what they can adjust in this program, as most blind customers can't really see colors, and I'm not sure if size can be seen by screenreaders either. I wonder, where can I find the parameter that makes certain widgets appear when triggered by radio buttons. For example, in "Step 19: Choice of Music".

				<div data-tab-body="step-19" style="visibility: visible;">

								<strong>Choice Of Music:<strong>"Oftentimes, wedding ceremonies are accompanied by music. When it comes to favorite music, the choice is up to you. Simply fill in the name(s) of the song(s), and the artist/composer of the selection. Next, enter the part of the ceremony where you would like the music to play. Then, select whether you want those gathered to "listen to" the music, or "Sing Together".
