virtual void casa::QtDisplayPanel::arrangeColorBars_	(	Bool	reorient = `False`,
		Bool	resizing = `False`
	)			`[protected, virtual]`

This routine corresponds to the old viewerdisplaypanel.g routine called 'arrangewedgerequirements'.

It responds to events which may require change to the relative placement or number of colorbars and their panels. 'reorient' is True if color bars are changing from horizontal to vertical (or vise versa); it helps determine how much action (if any) this routine needs to take. Only the pcResizing_() slot should set resizing=True; in this case, arrangeColorBars_ lets the PC take care of refresh.

void casa::QtDisplayPanel::creatingRstrDoc ( QDomDocument * restoredoc ) [signal]

Emitted when creating a restore xml doc.

QtDisplayPanelGui (in particular) can process by adding intormation to restoredoc.

void casa::QtDisplayPanel::cursorBoundary ( QtDisplayPanel::CursorBoundaryCondition ) [signal]

		const std::string &	dataType,

		QtDisplayData *&	dd,
		QString	origrestorefile,
		QString	restoredir
	)			`[protected, virtual]`

Tries to find existing DD (or create one from a file) that matches the given path.

Used for restoring DDs from a restore file. Several directories are checked, not just the one in path, to provide flexibility. If dd is non-zero, it is tested for suitability to path, datatype and displaytype. If dd is zero, the filesystem is searched and an attempt is made to create dd from a matching file (if any); if creation succeeds, dd will contain the new DD. Note: the DD will _not_ be registered automatically. origrestorefile and (current) restoredir aid in locating data files relative to the current restore file location.

void casa::QtDisplayPanel::dpHidden ( QtDisplayPanel * dp ) [signal]

Emitted when this QDP is hidden (closed).

Referenced by hideEvent().

String casa::QtDisplayPanel::dpState ( String restorefilename = "" )

Returns an xml String of displayPanel state.

This includes registered DDs and their options, panel options, animation and zoom state, etc. (QtDisplayPanelGui adds some gui/window state to this, and has file-saving interface). If a restorefilename where you intend to store the state is given, it will be set as attribute 'restorefile' of the root node. This allows data files to be moved and still restored later, relative to the restore file location.

virtual void casa::QtDisplayPanel::hold ( ) [virtual]

Hold and release of refresh.

In order to draw, every call to hold() must be accompanied by a subsequent call to release() (so don't neglect: beware of exceptions, e.g.). Calls can nest (they are counted). Panel may be deleted in a held state. Also, excess calls to release() will have no effect. The calls are propagated to the main PanelDisplay as well as to those used for color bars (and thence to their WorldCanvases).

void casa::QtDisplayPanel::imageRegionReady	(	ImageRegion	imgRegion,

Higher-level (ImageRegion) signal.

ddName is the name() of a registered [Lattice] QDD which conforms to the panel's current state (see DD:conformsTo()) and can compute true-region information from the latest 'mouse tool region event'. The ImageRegion parameter has the dimensions [and CS] of the DD's Image (currently, only Image PADDs are supported). It will correspond to the 2-D mouse region on its display axes. On 'animator' and 'hidden' axes (if any), the region will be 1 element wide, positioned at the current 'slice' for each of these axes.

void casa::QtDisplayPanel::oldDDRegistered ( QtDisplayData * ) [signal]

If you connect to any of these registrationChange signals and/or to ddCreated or ddRemoved signals (from QtViewerBase), the following are true when the slot is invoked: Any removed QDD still exists until after the signal's _directly_ connected slots have returned. Any new QDD has been created before the corresp. signal is emitted. The list of existing QDDs (QtViewerBase::dds()) and [un]registered QDDS (registeredDDs(), unregisteredDDs()) reflect the new state.

However, if you connect to a registrationChange signal _and_ to ddCreated or ddRemoved, it is not certain which slot will be invoked first.

Subset of the list above: those which should actually display now (which would exclude, e.g., a DD which is 'off blink').

These DDs are ordered so that in multipanel blink displays the order of images in panels is the same as the display order of their corresponding colorbars.

Vector<Float> casa::QtDisplayPanel::colorBarPanelSizes_ [protected]

Proportion of the pc_ that each color bar panel will use along the direction of colorbar thickness (e.g., along the horizontal axis for a vertical bar).

arrangeColorBars_() gets nominal sizes for colorbar panels from cbPanelSpace_(), and that is usually what they get.

Int casa::QtDisplayPanel::pcthsz_ [protected]

The following are used (only) by arrangeColorBars_() and its auxiliary routines, and are set for current conditions every time arrangeColorBars_() is called.

The margins (in 'pgp chars') are set onto the colorbar panels. PixelCanvas current sizes are in screen pixels. marginUnit_ is 1/65 of the PC's minimum dimansion. 'ln' and 'th' refer to the directions along the colorbar's length and thickness, respectively; 'ln' corresponds to vertical / horizontal according to the current orientation of color bars. mrgna_, mrgnb_ are margins in the colorbar thickness direction; mrgnb_ is where labelling occurs.
