QListWidget width

[colin207]

Hi

What, precisely, controls the default width of a QListWidget. I want a list widget that makes itself exactly wide enough to display the width of its widest item but no more.

E.g. I would have expected the following simple code to produce a dialog with a list box exactly wide enough to hold the items "fred" and "bloggs" but no more. Yet the dialog that gets shown has a list widget some 5 times wider than necessary. Why?

QDialog dlg(this);
	QListWidget* pListWidget = new QListWidget();
	new QListWidgetItem("Fred", pListWidget);
	new QListWidgetItem("Bloggs", pListWidget);
	QVBoxLayout* pLayout = new QVBoxLayout();
	pLayout->addWidget(pListWidget);
	dlg.setLayout(pLayout);
	dlg.exec();

QDialog dlg(this);
	QListWidget* pListWidget = new QListWidget();
	new QListWidgetItem("Fred", pListWidget);
	new QListWidgetItem("Bloggs", pListWidget);
	QVBoxLayout* pLayout = new QVBoxLayout();
	pLayout->addWidget(pListWidget);
	dlg.setLayout(pLayout);
	dlg.exec();

What is the simplest, clean and reliable way to control the list width width without relying on pixel width constants. Code needs to be properly portable. Thanks
