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)
pure virtualslot

Start a blank project.

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 
)
pure virtualslot

Open feature form.

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

Parameters
urlURL to open

void QgisInterface::projectRead ( )
signal

emitted when a project file is successfully read
