Hi Michaël!
The RCP has a new plugin system which (basically) consists of
* a PlugIn class with initialize(PlugInContext) and an execute method
without parameters.
* a PlugInContext class with getProgramModel(), getProgramFrame() and
getPlugInManager().
* a PlugInManager class which stores initialized PlugIns and provides them
through getPlugIn(className)
* a PlugInInstaller which is very similar to OpenJUMPs FeatureInstaller.
This system is -- as mentioned previously -- heavily inspired by SPSP [1],
completely written in Groovy and
introduces backward incompatible changes.
Thus an adapter plugin was created which forwards to a CompatPlugInContext
that extends the PlugInContext
of OpenJUMP.
Here is an example of a adapter method:
LayerViewPanel getLayerViewPanel() {
def programModel = this.niceJumpPlugInContext.getProgramModel()
return programModel.getActiveProject().getLayerViewPanel()
}
There are plenty of PlugIn e.g. MapPanelPlugIn, PropertiesPanelPlugIn,
ErrorHandlerPlugIn,
LoadDatasetPlugIn and LoadDatasetsDialogPlugIn.
The main idea was to control the system through the PlugIn provided by
PlugInManager. I also was
unhappy with the programmatic abilities with OpenJUMP. There were many
methods I wanted to
use marked as private. Others imposed swing windows, so I couldn't run them
completely
programmatically.
Thats why loading datasets are two PlugIns: LoadDatasetPlugIn provides a
programmatic interface and
LoadDatasetsDialogPlugIn uses the first plugin and opens a swing file
dialog.
