== ModelView framework in Marble ==
+
{{ Moved To Community }}
 
+
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 ===
+
* {{class|GeoDataDebugModel|kdeedu|4.x}}
+
It represents a data file, parsed into a {{class|GeoDataDocument|kdeedu|4.x}} tree structure.
+
 
+
It is used by the {{class|DataViewPlugin|kdeedu|4.x}} debug plugin (and is broken atm)
+
 
+
* {{class|GpxFileModel|kdeedu|4.x}}
+
It represents a list of gpx data file represented as {{class|GpxFile|kdeedu|4.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used as the model for the File List View ( which is accessible by running marble with --enableFileView ) but has since been replaced by another, more centralised, File Model. This new File Model is located in {{class|PlacemarkManager|kdeedu|4.x}}.
+
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 [[Projects/Marble/GPXStatus|Gpx Status]]
+
 
+
* {{class|MarbleGeometryModel|kdeedu|4.x}}
+
It represents the {{class|GeoDataGeometry|kdeedu}} and the {{class|GeoDataFeature|kdeedu|4.x}} items of the {{class|GeoDataDocument|kdeedu|4.x}} which contains all Placemarks.
+
 
+
It is used by the {{class|GeoRenderPlugin|kdeedu|4.x}} to access the list of placemarks.
+
 
+
=== QAbstractListModel ===
+
* {{class|FileViewModel|kdeedu|4.x}}
+
It represents the list of files opened. The {{class|PlacemarkManager|kdeedu|4.x}} appends the documents it opens, and the {{class|MarbleWidget|kdeedu}} appends the gpx files it opens.
+
 
+
It is used by the {{class|FileViewFloatItem|kdeedu|4.x}} and manipulated by the {{class|PlaceMarkManager|kdeedu|4.x}} and the {{class|MarbleModel|kdeedu|4.x}}.
+
 
+
* {{class|MarbleGeoDataModel|kdeedu|4.x}}
+
It represents a list of {{class|GeoDataDocuments|kdeedu|4.x}}. Only the {{class|PlacemarksPlugin|kdeedu|4.x}} uses it
+
 
+
It is used by no other code.
