Member Function Documentation

◆ application()

static qSlicerApplication* qSlicerApplication::application ( )

static

Return a reference to the application singleton.

◆ commandOptions()

Q_INVOKABLE qSlicerCommandOptions* qSlicerApplication::commandOptions ( ) const

Get commandOptions.

◆ confirmRestart

void qSlicerApplication::confirmRestart ( QString reason = QString() )

slot

Popup a dialog asking the user if the application should be restarted. If no reason is given, the text will default to ""Are you sure you want to restart?"

◆ currentLogFile

QString qSlicerApplication::currentLogFile ( ) const

slot

Path of the current log file

See also: recentLogFiles(), setupFileLogging()

◆ editNode

void qSlicerApplication::editNode	(	vtkObject *	,
		void *	,
		unsigned	long
	)

overrideprotectedslot

Request editing of a MRML node.

◆ handleCommandLineArguments()

void qSlicerApplication::handleCommandLineArguments ( )

overrideprotectedvirtual

Process command line arguments atfer the application event loop is started.

See also: handlePreApplicationCommandLineArguments(); qSlicerApplication::startupCompleted()

Reimplemented from qSlicerCoreApplication.

◆ handlePreApplicationCommandLineArguments()

void qSlicerApplication::handlePreApplicationCommandLineArguments ( )

overrideprotectedvirtual

Reimplemented from qSlicerCoreApplication.

◆ ioManager()

Q_INVOKABLE qSlicerIOManager* qSlicerApplication::ioManager ( )

Get IO Manager.

◆ isCodePageUtf8()

static Q_INVOKABLE bool qSlicerApplication::isCodePageUtf8 ( )

static

Return true if process code page is UTF-8. It is true for all MacOS and Linux versions and for Windows version 1903 (May 2019 Update) or later.

◆ launchDesigner

bool qSlicerApplication::launchDesigner ( const QStringList & args = QStringList() )

slot

Launch Qt Designer application (bundled with the application). If uiFile argument is specified then designer loads that UI file on startup.

◆ layoutManager()

Q_INVOKABLE qSlicerLayoutManager* qSlicerApplication::layoutManager ( ) const

Set/Get layout manager.

◆ loadFiles

bool qSlicerApplication::loadFiles	(	const QStringList &	filePaths,
		vtkMRMLMessageCollection *	userMessages = `nullptr`
	)

overrideslot

Override the qSlicerCoreApplication implementation to also show error messages in a popup window.

◆ logApplicationInformation()

virtual Q_INVOKABLE void qSlicerApplication::logApplicationInformation ( ) const

virtual

Log application information.

This function will log the following details:

Session start time
Slicer version
Operating system
Memory
CPU
Developer mode enabled
Additional module paths

Note: Starting the application with --application-information will also print the information to standard output.

See also: qSlicerCoreCommandOptions::displayApplicationInformation()

◆ mainWindow()

QMainWindow* qSlicerApplication::mainWindow ( ) const

Return a pointer on the main window of the application if any.

◆ nodeModule()

QString qSlicerApplication::nodeModule	(	vtkMRMLNode *	node,
		double *	confidence = `nullptr`
	)		const

Return the module name that is most suitable for editing the specified node. If a valid pointer is provided for confidence then the confidence value for the found module is returned. Confidence value = 0 means that the found module can probably not do much with that node, while 1.0 means that the found module is certainly the best module to manage than node.

◆ notify()

bool qSlicerApplication::notify	(	QObject *	receiver,
		QEvent *	event
	)

override

Avoid some crashes due to exceptions thrown during inside event handlers (such as slots). When exceptions are thrown from slots, Qt generates this message:

Qt has caught an exception thrown from an event handler. Throwing exceptions from an event handler is not supported in Qt. You must reimplement QApplication::notify() and catch all exceptions there.

so we follow the pattern suggested here:

https://stackoverflow.com/questions/13878373/where-am-i-supposed-to-reimplement-qapplicationnotify-function

◆ numberOfRecentLogFilesToKeep

int qSlicerApplication::numberOfRecentLogFilesToKeep ( )

slot

Number of recent log files to keep. Older log files are deleted automatically.

◆ onSlicerApplicationLogicModified()

void qSlicerApplication::onSlicerApplicationLogicModified ( )

overrideprotectedvirtual

Reimplemented from qSlicerCoreApplication.

◆ openNodeModule

void qSlicerApplication::openNodeModule	(	vtkMRMLNode *	node,
		QString	role = `QString()`,
		QString	context = `QString()`
	)

slot

Utility function that retrieve the best module for a node and trigger its associated QAction which eventually opens the module.

Note: qSlicerApplication is a temporary host for the function as it should be moved into a DataManager where module can register new node types/modules

◆ openSettingsDialog()

Q_INVOKABLE void qSlicerApplication::openSettingsDialog ( const QString & settingsPanel = QString() )

◆ pauseRender

void qSlicerApplication::pauseRender ( )

overrideslot

Equivalent to setRenderPaused(true)

See also: setRenderPaused

◆ recentLogFiles

QStringList qSlicerApplication::recentLogFiles ( )

slot

Paths of recent log files.

◆ renderPaused

void qSlicerApplication::renderPaused ( bool )

signal

Emitted when setRenderPaused() is called. This can be used by modules that manage their own viewers to pause and resume rendering.

See also: setRenderPaused

◆ resumeRender

void qSlicerApplication::resumeRender ( )

overrideslot

Equivalent to setRenderPaused(false)

See also: setRenderPaused

◆ setHasBorderInFullScreen

void qSlicerApplication::setHasBorderInFullScreen ( bool )

slot

When turning on OpenGL and using the full screen mode, menus and tooltips are no longer visible. By enabling hasBorderInFullScreen, a one-pixel border is added around the window, which fixes the problem. Border has to be enabled before going to full screen mode. This method has only effect when using Qt5 on Windows. See http://doc.qt.io/qt-5/windows-issues.html#fullscreen-opengl-based-windows

◆ setLayoutManager()

Q_INVOKABLE void qSlicerApplication::setLayoutManager ( qSlicerLayoutManager * layoutManager )

◆ setRenderPaused

void qSlicerApplication::setRenderPaused ( bool pause )

overrideslot

Calls setRenderPaused(pause) on the current layout manager. Emits pauseRenderRequested() if pause is true and resumeRenderRequested() if pause is false. The caller is responsible for making sure that each setRenderPaused(true) is paired with setRenderPaused(false).

See also: qMRMLLayoutManager::setRenderPaused()

◆ settingsDialog()

Q_INVOKABLE ctkSettingsDialog* qSlicerApplication::settingsDialog ( ) const

◆ setToolTipsEnabled()

void qSlicerApplication::setToolTipsEnabled ( bool enable )

Enable/Disable tooltips.

TODO See http://doc.trolltech.com/4.6/qapplication.html#commitData and http://doc.trolltech.com/4.6/qsessionmanager.html#allowsInteraction

◆ setupFileLogging()

void qSlicerApplication::setupFileLogging ( )

protected

Set up file logging. Creates and sets new log file and deletes the oldest one from the stored queue

◆ startupCompleted

void qSlicerApplication::startupCompleted ( )

signal

Emitted when the startup phase has been completed.

Startup is complete when all the modules have been initialized and the main window is shown to the user.

Note: If the application is started without the mainwindow, the signal is emitted after the modules are initialized.

See also: qSlicerAppMainWindow::initialWindowShown()
