lupdate not adding entries to .ts files

Perdrix

Here's the entry that wasn't added:

	setToolTip(tr("You can use the Up-Arrow, Right-Arrow, Left-Arrow, Down-Arrow;\n"
		"Page-Up and Page-Down keys to move a slider after you have selected it\n"
		"with the mouse."));

it's perfectly valid C++ but I suspected lupdate was tripping up on the character string split over several lines.

So I tried this:

	setToolTip(tr("You can use the Up-Arrow, Right-Arrow, Left-Arrow, Down-Arrow;\n\
	Page-Up and Page-Down keys to move a slider after you have selected it\n\
	with the mouse."));

but that didn't work either, so I tried:

setToolTip(tr("You can use the Up-Arrow, Right-Arrow, Left-Arrow, Down-Arrow;\nPage-Up and Page-Down keys to move a slider after you have selected it\nwith the mouse."));

sad to say that too failed.

Yes the header file has Q_OBJECT:


class QLinearGradientCtrl : public QWidget
{
	Q_OBJECT
	Q_PROPERTY(QLinearGradient gradient READ gradient WRITE setGradient)
	Q_PROPERTY(int gradientWidth READ gradientWidth WRITE setGradientWidth)
	Q_PROPERTY(Orientation orientation READ orientation WRITE setOrientation)
	Q_PROPERTY(int selectedPeg READ selected WRITE setSelected NOTIFY pegSelChanged)
	Q_PROPERTY(QGradientStop selectedStop READ selectedStop)
	Q_PROPERTY(bool pegsOnLeftOrBottom READ pegsOnLeftOrBottom WRITE setPegsOnLeftOrBottom)
	Q_PROPERTY(bool pegsOnRightOrTop READ pegsOnRightOrTop WRITE setPegsOnRightOrTop)
	Q_PROPERTY(bool showToolTips READ showToolTips WRITE setShowToolTips)

typedef QWidget
		Inherited;

As always - minimize your code until the problem goes away or you can show us a minimal reproducer.

All I have to add is that lupdate said:

QLinearGradientCtrl.cpp:46: tr() cannot be called without context

Does that guide me to a solution?

Are you sure, everything is as it should be ?

Base class properly initialised ?
Q_OBJECT and not Q_GADGET used ?
tr() function in the actually scope of the class (QLinearGradientCtrl) and not in a lambda or such shenanigans ?

use QCoreApplication::translate() and provide your own context scope

Yes I used Q_OBJECT and yes the class is initialised. In the end I gave up and use QCoreApplication::translate("QLinearGradientCtrl", "text") as tr("text") wasn't working.

QLinearGradientCtrl::QLinearGradientCtrl(QWidget * parent, QColor start, QColor end) :
	QWidget(parent),
	m_Gradient(0, 0, 1, 0),
	m_Width(GCW_AUTO),
	selectedPeg(NONE),
	lastSelectedPeg(NONE),
	m_LastPos(0),
	m_showToolTips(true),
	m_Orientation(Orientation::Auto),
	startPegStop(0),
	m_LeftDownSide(true),
	m_RightUpSide(false)
{
	m_ToolTipFormat = "&SELPOS\nPosition: &SELPOS Colour: R &R G &G B &B\nColour: R &R G &G B &B\nColour: R &R G &G B &B\nDouble Click to Add a New Peg";
	//m_Impl = new QLinearGradientCtrlImpl(this);
	m_Gradient.setColorAt(0, start);
	m_Gradient.setColorAt(0.001, start);
	m_Gradient.setColorAt(0.999, end);
	m_Gradient.setColorAt(1, end);
	setFocusPolicy(Qt::StrongFocus);		// Make sure we get key events.

	stops = m_Gradient.stops();				// Grab the gradient stops
	endPegStop = stops.size() - 1;

	setToolTip(QCoreApplication::translate("QLinearGradientCtrl",
		"You can use the Up-Arrow, Right-Arrow, Left-Arrow, Down-Arrow;\n"
		"Page-Up and Page-Down keys to move a slider after you have selected it\n"
		"with the mouse."));
}

Is how it now reads...
