You have to have two slots. One that tracks the value (and in my case
updates things if the value seems safe), and one that forces the update if
the user leaves the field.

Exactly, that's the point.

Yes, which is why I implemented it like this:

	connect(ui.gfhigh, SIGNAL(valueChanged(int)), plannerModel, SLOT(setGFHigh(int)));
	connect(ui.gflow, SIGNAL(valueChanged(int)), plannerModel, SLOT(setGFLow(int)));
	connect(ui.gfhigh, SIGNAL(editingFinished()), plannerModel, SLOT(triggerGFHigh()));
	connect(ui.gflow, SIGNAL(editingFinished()), plannerModel, SLOT(triggerGFLow()));

and then later

void DivePlannerPointsModel::setGFHigh(const int gfhigh)
	tempGFHigh = gfhigh;
	// GFHigh <= 34 can cause infinite deco at 6m - don't trigger a
	// recalculation
	// for smaller GFHigh unless the user explicitly leaves the field
	if (tempGFHigh > 34)

void DivePlannerPointsModel::triggerGFHigh()
	if (diveplan.gfhigh != tempGFHigh) {
		diveplan.gfhigh = tempGFHigh;

void DivePlannerPointsModel::setGFLow(const int ghflow)
	tempGFLow = ghflow;

void DivePlannerPointsModel::triggerGFLow()
	if (diveplan.gflow != tempGFLow) {
		diveplan.gflow = tempGFLow;

This may not be super elegant, but I think it gets the job done and avoid
unneccessary "DataChanged()" signals in the process.

Worst case the warning ends up being English. We'll live.
