"drawable.list"The purpose of this class is to store and manage a collection of '>drawable objects. These collections are to be used by tk.browse and browsePlot as input.
Objects can be created by the drawable.list constructor, and edited / created using the tk.tracks Tcl-tk interface.
By default, the drawable.list$add() method is only able to handle objects from '>drawable-inheriting classes saved in RDT or RDS individual files. This can however be extended defining functions named drawableFromFile.EXTENSION and drawableFromClass.CLASS, in the global environment or a package. Such a function will take the same arguments as the drawable.list$add() method, and will only have to return a '>drawable-inheriting object.
classes:Read-only, returns a vector of objects classes.
count:Read-only, returns the length of objects, as a single integer.
files:Character vector, the paths where each drawable object is to be stored.
hidden:Logical vector, whether each object is to drawn or hidden in plots.
names:Read-only, returns a vector of objects 'name' fields.
objects:add(file, track = , hidden = , ...):Add a track to the list. - file : single character value, the path to the file containing the 'drawable' object to add. - track : a 'drawable' object to add. If NULL, will be extracted from 'file'. - hidden : single logical value, whether the track is to be shown on plots or hidden. This value can be changed later. - ... : further arguments to be passed to drawableFromFile.EXTENSION or drawableFromClass.CLASS, if relevant.
check(warn = ):Raises an error if the object is not valid, else returns TRUE
fix.files(parent = ):Edit drawable list using a Tcl-tk GUI - parent : tcltk parent frame for inclusion, or NULL.
fix.param(selection = , parent = ):Edit drawing parameters using a Tcl-tk GUI - selection : single integer value, the position of the track selected in the list. - parent : tcltk parent frame for inclusion, or NULL.
get(index, what = ):Returns a single 'what' from the series - index : single numeric value, the position of the track to get. - what : single character value, the field to be exracted.
getByClasses(classes, what = ):Returns a subset of 'what' from the series, querying by class inheritance - classes : character vector, the class names of the objects to get (inheriting classes are picked too). - what : single character value, the field to be exracted.
getByNames(names, what = ):Returns a subset of 'what' from the series, querying by track name - names : character vector, the names of the objects to get. - what : single character value, the field to be exracted.
getByPositions(positions, what = ):Returns a subset of 'what' from the series, querying by position - positions : integer vector, the positions of the objects to get. - what : single character value, the field to be exracted.
getChromEnd(chrom):Returns as a single integer value the maximal ending position of the object descriptions of the given chromosome. - chrom : single integer, numeric or character value, the chromosomal location.
initialize(files = , objects = , hidden = , ...):moveDown(toMove):Increases the position of a track, switching position with the next one - toMove : single numeric value, the position of the track to move.
moveUp(toMove):Decreases the position of a track, switching position with the previous one - toMove : single numeric value, the position of the track to move.
remove(toRemove):Remove one or many tracks from the list - toRemove : numeric vector, the positions of the tracks to remove.
