Detailed Description

QgisInterface Abstract base class defining interfaces exposed by QgisApp and made available to plugins.

Only functionality exposed by QgisInterface can be used in plugins. This interface has to be implemented with application specific details.

QGIS implements it in QgisAppInterface class, 3rd party applications could provide their own implementation to be able to use plugins.

virtual void QgisInterface::newProject ( bool thePromptToSaveFlag = false )

void QgisInterface::newProjectCreated ( )

signal

emitted when starting an entirely new project

Note: This is similar to projectRead(); plug-ins might want to be notified that they're in a new project. Yes, projectRead() could have been overloaded to be used in the case of new projects instead. However, it's probably more semantically correct to have an entirely separate signal for when this happens.

Added in v1.6

virtual bool QgisInterface::openFeatureForm	(	QgsVectorLayer *	l,
		QgsFeature &	f,
		bool	updateFeatureOnly = `false`
	)

virtual Q_DECL_DEPRECATED void QgisInterface::openURL	(	QString	url,
		bool	useQgisDocDirectory = `true`

By default the QGIS doc directory is used as the base for the URL. To open a URL that is not relative to the installed QGIS documentation, set useQgisDocDirectory to false.

Parameters

url	URL to open
useQgisDocDirectory	If true, the URL will be formed by concatenating url to the QGIS documentation directory path (prefix/share/doc)

void QgisInterface::projectRead ( )
