Constructor Detail

StyleSelectorListModel

public StyleSelectorListModel(File dir,
                              SelectorFilter filter,
                              String fileExtension)

Creates a new instance of the model for the list in the Style Selector window where the styles are stored in the dir (root directory) param.

The currentElement defines which element is pre-selected.

The filter is a user defined filter used to know which elements in the folder are accepted or rejected for this list and it is used to avoid mixing marker styles for polygons for example.

fileExtension param defines the extension of the file to be parsed. This is like that to enable inheritance of this class to other file selector such as StyleSelector.

Parameters:

dir, - the root dir where styles are located.

currentElemet, - the element to be pre-selected.

filter, - the filter used to show or hide some elements.

fileExtension, - file extension used for the files to be parsed.
