void casa::QtDisplayData::axisChanged	(	String	,
		String	,
		String	,
		std::vector< int >
	)			`[signal]`

(mkApr2012) axisChanged and axisChangedProfile have the identical functionality, to send out the names of the current x/y/z axes.

The profiler needs to be notified first such subsequent plot request from regions are accepted. For that reason there is the signal axisChangedProfile which connects to the profiler and is emitted prior to axisChanged (in QtDisplayData::checkAxis())

void casa::QtDisplayData::axisChangedProfile	(	String	,
		String	,

		std::vector< int >

virtual WedgeDD* casa::QtDisplayData::colorBar ( ) [inline, virtual]

(0 if none. It will exist if hasColorBar() is True). (Not for general use).

References colorBar_.

void casa::QtDisplayData::colorBarChange ( ) [signal]

Emitted when color bars may need rearrangement on panels where this QDD is registered.

QDP connects this to its checkColorBars_() slot.

virtual Float casa::QtDisplayData::colorBarLabelSpaceAdj ( ) [virtual]

Used (by QtDisplayPanel) to compute margin space for colorbar labels.

It is the (pgplot) character size for colorbar labels (default 1.2) times a label space 'adjustment' user option (default 1.).

virtual Float casa::QtDisplayData::colorBarSizeAdj ( ) [inline, virtual]

User-requested adjustment to colorbar thickness (will probably remain at the default value of 1).

Used by QtDisplayPanel to aid in sizing colorbar panels.

virtual Bool casa::QtDisplayData::getCMShiftSlope ( Vector< Float > & params ) const [virtual]

Get/set colormap shift/slope ('fiddle') and brightness/contrast settings.

(At present this is usually set for the PC's current colormap via mouse tools. These may want to to into get/setOptions (thus into guis) eventually...). Return value will be False if DD has no colormap [at present].

virtual void casa::QtDisplayData::getInitialAxes_	(	Block< uInt > &	axs,
		const IPosition &	shape,
		const DisplayCoordinateSystem &	cs
	)			`[protected, virtual]`

Heuristic used internally to set initial axes to display on X, Y and Z, for PADDs.

shape should be that of Image/Array, and have same nelements as axs. On return, axs[0], axs[1] and (if it exists) axs[2] will be axes to display initially on X, Y, and animator, respectively. If you pass a CS for the image, it will give special consideration to Spectral [/ Direction] axes (users expect their spectral axes on Z, e.g.)

virtual Record casa::QtDisplayData::getOptions ( ) [virtual]

This is similar to a 'Parameter Set', containing option types, default values, and meta-information, suitable for building a user interface for controlling the DD.

		Bool	allPols = `False`,
		Bool	allRAs = `False`,
		Bool	allDECs = `False`,

	)			`[virtual]`

Convert 2-D 'pseudoregion' (or 'mouse region' Record, from the region mouse tools) to a full Image Region, with same number of axes as the DD's Lattice (and relative to its DisplayCoordinateSystem).

Return value is 0 if the conversion can't be made or does not apply to this DD for any reason (ignored by non-Lattice DDs, e.g.).

If allChannels==True, the region is extended along spectral axis, if it exists (but ONLY if the spectral axis is not also on display; the visible mouse region always defines region shape on the display axes).

If allAxes is True, the region is extended over all (non-display) axes (including any spectral axis; allAxes=True makes the allChannels setting irrelevant).

If both allchannels and allAxes are False (the default), the region will be confined to the currently-displayed plane.

-->If the returned ImageRegion* is non-zero, the caller -->is responsible for deleting it.

Set named colormap onto underlying dd (called from public setOptions()).

Pass "" to remove/delete any existing colormap for the QDD. In the case that no colormap is set on a dd that needs one (raster dds, mostly), the drawing canvas will provide a default. See ColormapDefinition.h, and the Table gui/colormaps/default.tbl (in the data repository) for the list of valid default colormap names (and information on creating/installing custom ones). If an invalid name is passed, an (ignorable) error message is signalled, and the dd's colormap will remain unchanged.
