I have some code that includes this snippet:
String[] prevNatures = description.getNatureIds();
String[] newNatures = new String[prevNatures.length + 1];
System.arraycopy(prevNatures, 0, newNatures, 0, prevNatures.length);
newNatures[prevNatures.length] = TMNature.ID;
description.setNatureIds(newNatures);
// Create the new project operation.
final IProject projectHandle = project;
WorkspaceModifyOperation op = new WorkspaceModifyOperation() {
protected void execute(IProgressMonitor monitor) throws
CoreException {
createNewProject(projectHandle, description, monitor);
}
};
// Run the new project creation operation. If either exception
// occurs, we return a null project to indicate the operation was
// cancelled.
try {
context.run(true, true, op);
}
I've discovered that if I move the code that adds TMNature.ID to some place
after the project creation, the project no longer behaves as expected once
it is created. For example, it just doesn't appear at all in certain
perspectives and it may or may not have the corrrect projectNatureImage. I
do know that if I move this code, I have to set the description back in the
project with:
project.setDescription(description, null);
So, if I want the nature-setting code elsewhere (I'm thinking of a common
method to create a basic project, which can be augmented with one or more
natures later), what API call(s) do I need to add to let all interested
parties in the UI know about the new natures?
