Interface class for file and object handling.
This interface class has to be fully implemented. When you want to support save and load for an object type you have to implement all functions in this class. The core manages the load and save interaction and gives the load and save actions to your plugin. The decision which plugin is called for saving an object depends on your supportedTypes() and the filters defined by your plugin.
Definition at line 70 of file FileInterface.hh.
| virtual int FileInterface::addEmpty | ( | ) | [pure virtual, slot] |
Create an empty object.
When this slot is called you have to create an object of your supported type.
| virtual QString FileInterface::getLoadFilters | ( | ) | [pure virtual] |
Return the Qt Filters for Filedialogs when loading files (e.g. "Off files ( *.off )" )
Referenced by Core::loadPlugin().
| virtual QString FileInterface::getSaveFilters | ( | ) | [pure virtual] |
Get the Qt Filters for Filedialogs when saving files (e.g. "Off files ( *.off )" )
Referenced by Core::loadPlugin().
| virtual int FileInterface::loadObject | ( | QString | ) | [pure virtual, slot] |
Load an object from the given file.
The Core will call this slot if you should load a file. The core will check if you support the given file type depending on the provided filters and dataTypes ( see supportedType and getLoadFilters )
| virtual QWidget* FileInterface::loadOptionsWidget | ( | QString | ) | [pure virtual] |
You can provide a special widget showing options for loading your file types depending on the current filter
_currentFilter: one filter from loadFilters
Return 0 when you dont need one
| virtual bool FileInterface::saveObject | ( | int | , | |
| QString | ||||
| ) | [pure virtual, slot] |
Save an object from the given file.
The Core will call this slot if you should save an object to a file. The core will check if you support the given object depending on the provided dataTypes ( see supportedType ). Additionally to the filename you get the id of the object to save
| virtual QWidget* FileInterface::saveOptionsWidget | ( | QString | ) | [pure virtual] |
You can provide a special widget showing options for saving your file types depending on the current filter
_currentFilter: one filter from saveFilters
Return 0 when you dont need one
| virtual DataType FileInterface::supportedType | ( | ) | [pure virtual] |
Return your supported object type( e.g. DATA_TRIANGLE_MESH )
TODO : Support for adding new datatypes at runtime
Referenced by Core::loadPlugin().
| virtual QString FileInterface::typeName | ( | ) | [pure virtual] |
Return the name of your supported type (e.g. "Triangle Mesh"
