Returns

Application name.

qtlWidgetAncestor()

QWidget* qtlWidgetAncestor

(

QObject *

object

)

[in]	maxDepth	Maximum depth of children to explore. A negative number means unlimited.

qtlObjectHierarchy()

QString qtlObjectHierarchy	(	QObject *	object,
		const QString &	prefix = QString(),
		int	maxDepth = -1
	)

Dump an object hierarchy in a string.

Parameters

[in]	object	Root object of the hierarchy to dump.
