Constructor & Destructor Documentation

casa::QtViewerBase::QtViewerBase ( bool is_server = false )

casa::QtViewerBase::~QtViewerBase ( )

Member Function Documentation

Bool casa::QtViewerBase::dataDisplaysAs	(	String	datatype,
		String &	displaytype
	)

Returns True iff datatype is a vaild viewer datatype and displaytype is valid for the datatype.

If the former is true but the latter isn't, displaytype is [re]set to the default displaytype for the datatype.

virtual void casa::QtViewerBase::dpCreated	(	QtDisplayPanelGui *	newDP,
		QtDisplayPanel *	panel
	)		`[virtual]`

Only to be used by QtDisplayPanels, to inform this class of their creation.

(C++ should allow individual methods to be 'friend'ed to outside classes...).

virtual void casa::QtViewerBase::dpDestroyed_ ( QObject * ) [protected, virtual, slot]

Connected by this class, (only) to QDPs' destroyed() signals (for maintenance of the list of existing QDPs).

virtual void casa::QtViewerBase::dpHidden_ ( QtDisplayPanel * ) [protected, virtual, slot]

Connected by this class, (only) to QDPs' dpHidden() signals (for checking on open QDPs -- will quit if none are left open).

bool casa::QtViewerBase::exiting ( ) [inline]

Definition at line 142 of file QtViewerBase.qo.h.

References qtviewer_app_exit.

static String casa::QtViewerBase::fileType ( const String pathname ) [static]

function to aid typing files of interest to the viewer.

Moved from QtDataManager to be available for non-gui use. Returns user interface Strings like "Measurement Set".

static String casa::QtViewerBase::filetype ( const String pathname ) [static]

similar to above; returns internal DD datatype names like "ms" (or else 'nonexistent', 'unknown').

virtual void casa::QtViewerBase::hold ( ) [virtual, slot]

Hold/release of (canvas-draw) refresh of all QDPs.

(NB: does not concern enabling of Qt Widgets). Call to hold() must be matched to later call of release(); they can be nested. It is sometimes efficient to wait until several changes are complete and then redraw everything just once.

static Bool casa::QtViewerBase::isRestoreFile	(	String	filename,
		QDomDocument &	restoredoc
	)		`[static]`

Does the given file pathname hold a readable file with valid ID and form as a viewer restore xml document? (If so, contents are set onto restoredoc).

static Bool casa::QtViewerBase::isRestoreString	(	String	xmlState,
		QDomDocument &	restoredoc
	)		`[static]`

Does the given String have valid ID and form as viewer restore xml? (If so, contents are set onto restoredoc).

virtual QtMouseToolState* casa::QtViewerBase::mouseBtns ( ) [inline, virtual]

Return the common QtMouseToolState that all mouse tool users should share.

Definition at line 76 of file QtViewerBase.qo.h.

References msbtns_.

virtual const QtMouseToolState* casa::QtViewerBase::mouseBtns ( ) const [inline, virtual]

Definition at line 77 of file QtViewerBase.qo.h.

References msbtns_.

virtual Int casa::QtViewerBase::nOpenDPs ( ) [virtual]

The number of open QtDisplayPanels.

(More efficient than the equivalent openDPs().len(), if the number is all that's needed).

virtual List<QtDisplayPanelGui*> casa::QtViewerBase::openDPs ( ) [virtual]

The list of QtDisplayPanels that are not closed.

virtual void casa::QtViewerBase::quit ( ) [virtual, slot]

Closes all open panels, which will exit the Qt loop.

Note that the loop can be restarted (and is, in interactive clean, e.g.), with existing widgets intact. This does not in itself delete objects or exit the process, although the driver program might do that. Also, some of the panels may have WA_DeleteOnClose set, which would cause their deletion (see, e.g., QtViewer::createDPG()).

Reimplemented in casa::QtViewer.

virtual void casa::QtViewerBase::release ( ) [virtual, slot]

bool casa::QtViewerBase::server ( ) const [inline]

Definition at line 72 of file QtViewerBase.qo.h.

References server_.

static String casa::QtViewerBase::toString ( Vector< Float > values ) [static]

Utility routines to convert between Vector<Float> and String.

static String casa::QtViewerBase::toString ( Vector< Double > values ) [static]

static Vector<Double> casa::QtViewerBase::toVectorD	(	String	values,
		Bool *	ok = `0`
	)		`[static]`

static Vector<Float> casa::QtViewerBase::toVectorF	(	String	values,
		Bool *	ok = `0`
	)		`[static]`

Vector<Vector<Int> > casa::QtViewerBase::dataDisplaysAs_ [protected]

e.g.

dataDisplaysAs_[IMAGE] will be {RASTER, CONTOUR, VECTOR, MARKER} dataDisplaysAs_[datatype][0] will be the default displaytype for that datatype.

List<QtDisplayPanelGui*> casa::QtViewerBase::qdps_ [protected]

Existing QtDisplayPanels (whether 'closed' or not, as long as not deleted).

Unlike QDDs, QtViewerBase does not create or delete QDPs, it just tries to keep track of them. Note that by default, 'closed' DPs are simply not 'visible' (see QWidget::isVisible()), though they are not deleted unless their owner does it. An owner can also revive (show) a 'closed' QDP. The publicly-available list openDPs() shows only those which are not closed. Minimized or covered DPs are still considered 'open'.
