ModelView framework in Marble
Marble uses Qt's Model/View framework as a way to signal updates to a model to interested parts. In that respect, a Model class can wrap any possible data.
Here is the list of Model class, and a description of how they are used.
QAbstractItemModel
- Expression error: Unrecognized word "x".
It represents a data file, parsed into a Expression error: Unrecognized word "x". tree structure.
It is used by the Expression error: Unrecognized word "x". debug plugin (and is broken atm)
- Expression error: Unrecognized word "x".
It represents a list of gpx data file represented as Expression error: Unrecognized word "x".
This was originally intended to but used as the model for the File List View ( which is accessible by running marble with --enableFileView ) but has since been replaced by the FileViewModel.
The model that is in the GpsLayer is currently only being used as a collection class and is deprecated. This, along with the whole current GPX implementation, needs to be removed and updated to the current concepts in Marble. See Gpx Status
- Expression error: Unrecognized word "x".
It represents the GeoDataGeometry and the Expression error: Unrecognized word "x". items of the last opened Expression error: Unrecognized word "x"..
It is used by the Expression error: Unrecognized word "x". to access the list of vector data to draw it.
QAbstractListModel
- Expression error: Unrecognized word "x".
It represents the list of opened files. The Expression error: Unrecognized word "x". appends the documents it opens, and the MarbleWidget appends the gpx files it opens.
It is used by the Expression error: Unrecognized word "x". and manipulated by the Expression error: Unrecognized word "x". and the Expression error: Unrecognized word "x"..
- Expression error: Unrecognized word "x".
It represents a list of Expression error: Unrecognized word "x".. Only the Expression error: Unrecognized word "x". uses it
It is used by no other code.
- Expression error: Unrecognized word "x".
It represents the list of all Placemarks of all opened kml files. the Expression error: Unrecognized word "x". appends all the placemarks after reading a file.
It is used by the Expression error: Unrecognized word "x". to provide the list of placemarks to search for, and by the Expression error: Unrecognized word "x". to determine layouting on the map.
