Text in QPushButton not fully placed. How can it be moved (e.g., to be in two rows) and placed in full?

Translation of text QPushButton:
```
QPushButton button;
button->setText("Multiline\nText");
```
If the text is placed in the button, for example, by the following design:
```
if (button->fontMetrics().elidedText(button->text(), Qt::ElideMiddle, button->geometry().width()) != button->text())
{
    // Текст не помещается.
}
```
But somehow it doesn't work out exactly. Somewhere, I think there's still a framework for the withdrawal.

A request to show the duplicates:select r.id, count(1) from TESC4.JOURNAL_RECORDS r inner join TESC4.JOURNAL_RECORDS ref on ref.ORIGINAL_REC_ID = r.ID where r.edit_state in (0, 1, 2) and r.journal_id = :JOURNAL_ID and r.journal_table_id = :JOURNAL_TABLE_ID and r.primary_date >= :START_DATE and r.primary_date < :END_DATE group by r.id having count(1) > 1 The request, similar to your, but without questioning, will not be in error if there are any duplicates, rather the question of:select * from ( select r.id, ref.OPERATOR_ID as oper, f.STRING_VALUE as INSTRUMENT_NUMBER from TESC4.JOURNAL_RECORDS r left join TESC4.JOURNAL_RECORDS ref on ref.ORIGINAL_REC_ID=r.ID left join TESC4.JOURNAL_FIELD_DATA f on r.id=f.journal_record_id and field_name='INSTRUMENT_NUMBER' where r.edit_state in (0,1,2) and r.journal_id=:JOURNAL_ID and r.journal_table_id=:JOURNAL_TABLE_ID and r.primary_date>=:START_DATE and r.primary_date<:END_DATE ) where INSTRUMENT_NUMBER like '%121339%'; A group could be placed on this request to see what is being repeated.

We can track the current element in the outlet by sending the signal http://doc.qt.io/qt-5/qcombobox.html#currentIndexChanged Class http://doc.qt.io/qt-5/qcombobox.html by grade ComboBoxDelegate♪ The signal should be sent in the method http://doc.qt.io/qt-5/qstyleditemdelegate.html#createEditor Delegates ' class. Example of implementation:class ComboBoxDelegate : public QStyledItemDelegate { Q_OBJECT ... public: QWidget* ComboBoxDelegate::createEditor(QWidget parent, const QStyleOptionViewItem &/ option /, const QModelIndex &/ index /) const { QComboBox editor = new QComboBox(parent); editor->addItem(...); editor->addItem(...); ... // "Перебрасываем" сигнал на уровень класса. connect(editor, SINGAL(currentIndexChanged(int)), SINGAL(currentIndexChanged(int)); return editor; } signals: void currentIndexChanged(int index); ... } So in the code that creates copies of the class ComboBoxDelegatethe current element may be intercepted.Something like that I already described. https://ru.stackoverflow.com/a/486399/200169 ♪

The answer is simple. Rewrite the calculation, added the picel 10. Why such conduct, and why it is necessary to add 10 piccells, I can't assume, most likely, in other applications, by the way of the Vindrovsky, Margin is in control.

Main and secondary flows can also be interacted through a static method void QCoreApplication::postEvent(QObject* receiver,QEvent* event)♪ This can be done as follows:Create class, derivative QEvent♪ Class attributes are the data we transmit between flows.For example:MyEvent.h-file#include <QEvent> class MyEvent : public QEvent { public: MyEvent(const QString& message) : QEvent(QEvent::User) {_message = message;} ~MyEvent() {} QString message() const {return _message;} private: QString _message; }; Here. QEvent::User - User identifier, _message - data transmitted between flows.♪ Data sender (secondary flow) in the pile creates the object of a user-type event, assigns the relevant attributes and places it in the course of events of the data recipient.For example:void MyThread::run() { forever { ... MyEvent* myEvent = new MyEvent("Hello GUI! This is another thread."); QCoreApplication::postEvent(gui, myEvent); ... } } Here. gui - an indicator on the data recipient.♪ Data recipient (GUI flow) Redesign virtual method bool QObject::event(QEvent* event)♪ The method deals with all the events that come from its course of events. If the identifier of the event is a user type, we are transforming the type of event into a user-friendly, followed by its attributes, and returning the value true so that it does not transfer the event to the parent class. If the identifier of the event has a different type from the user, then we are transferring it to the parent class for further processing.For example:Widget.h-fail (GUI- flow)class Widget : public QWidget, public Ui::WidgetClass { Q_OBJECT public: Widget(QWidget *parent = 0); ~Widget(); protected: bool event(QEvent* event); ... Widget.cpp-Fail (GUI- flow)bool Widget::event(QEvent* event) { if (event->type() == QEvent::User) { MyEvent* postedEvent = static_cast<MyEvent*>(event); textEdit->append(postedEvent->message()); return true; } return QWidget::event(event); } It is also fair to transfer events in the reverse direction, from GUI to secondary flow. An example of the transfer of events in both directions can be downloaded https://dl.dropbox.com/u/103588168/HC_3.tar.gz ♪

You're in this line.qDebug() << socket->readAll(); The data are coming. It's enough to keep them in line, then use the split method and break them in line. The first line will contain three elements that can be broken by the same split.ordinary typeGET /pub/WWW/TheProject.html HTTP/1.1 First is a method. There's not many options. Usually it's GET/POST/PUT/DELETE, but it's possible to insert it. It corresponds to what they requested. The next thing you said, "the different directories." That's what you need. And the end is the HTTP version, but it's probably just that you can just ignore.I mean, somewhere like that.QStringList h = QString(socket->readAll()).split('\n'); QStringList f = h.split(' '); QString method = f[0]; QString path = f[1]; // дальше решаем. QString response = "HTTP/1.1 200 OK\r\n\r\n%1"; if (path == '/date") { socket->write(response.arg(QDateTime::currentDate().toString()).toUtf8()); } else if (path == "/time") { socket->write(response.arg(QDateTime::currentTime().toString()).toUtf8()); } else { socket->write(response.arg("error"); } socket->disconnectFromHost(); Of course, this realization is very simple and has many shortcomings. But she has to work.

I always suspected that Blade was evil, and now I'm convinced.The ability to write a code in any RBP template is a great opportunity to shoot yourself in the leg. And in the end, here we see a business logic flowing and smelling in a hat. To do the right thing, we need to get the whole business log out of the template. And plus we have to make a proper storage of parameters, without these terrible commas. But since this will be very difficult for the author and has no direct bearing on the matter, at least the str_replace() should be used to produce the mass. And it's a good set to take the cycle to the template.As a result, json_decode and explode() are routinely removed in a counter-eller, and a code remains in the template. @foreach($prod[0]->characteristic as $char) {{ $char }}<br>
