Hi Joe,
the code you are using uses a lot of BlueBerry internal classes. All the
classes you mention in point 1) are *not* part of the BlueBerry API and
their implementation could change anytime (and break your code). We
cannot support the usage of internal classes - if you have to include a
header file starting with "internal/..." you should think twice if you
can achieve your goals in another way. Additionally, this approach only
works on Linux, since internal class symbols are not exported on Windows
(you would get linker errors).
Please post more details about the problem you are trying to solve, so
we might be able to figure out a "supported" way of doing it.
Best,
Sascha
P.S.: If you really want to rely on internal classes, try using
workbenchPage->GetActiveEditor(); instead of
workbenchPage->GetActivePart(); in the second line of your method. The
result of "GetActivePart" could be a view *or* editor. If it is a view,
it is contained in a ViewSashContainer. The EditorSashContainer contains
the editor parts, but is itself contained in the "root"
ViewSashContainer (which you probably got).

Hi Mitk Users,
I found some code that does exactly what I needed - in order to split
the editors on different Part Stacks after I add a new editor. Part of
the problem is that the code I found is from Eclipse and is written in
Java.
I was able to convert this code to run in MITK, however, the behavior
is not correct as I expected (this was probably due to guessing code
substitutions).
1) In order to use this code correctly I need to understand the
relations between:
WorkbenchPage, WorkbenchPart, WorkbenchPartSite, PartPane,
LayoutPart, LayoutContainer, EditorSashContainer, and PartStack
Please send any documentation showing how to access the
EditorSashContainer moving through the other classes.
2) Here is the Eclipse Java code:
/**
* Split the editor area if there is at least two editors in it.
*/
private void splitEditorArea() {
IWorkbenchPage workbenchPage =
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
IWorkbenchPart part = workbenchPage.getActivePart();
PartPane partPane = ((PartSite) part.getSite()).getPane();
* LayoutPart layoutPart = partPane.getPart();*
IEditorReference[] editorReferences =
workbenchPage.getEditorReferences();
// Do it only if we have more that one editor
if (editorReferences.length > 1) {
// Get PartPane that correspond to the active
editor
PartPane currentEditorPartPane = ((PartSite)
workbenchPage.getActiveEditor().getSite()).getPane();
EditorSashContainer editorSashContainer = null;
ILayoutContainer rootLayoutContainer =
layoutPart.getContainer();
if (rootLayoutContainer instanceof LayoutPart) {
ILayoutContainer cont =
((LayoutPart) rootLayoutContainer).getContainer();
if (cont instanceof
EditorSashContainer) {
editorSashContainer =
((EditorSashContainer) cont);
}
}
/*
* Create a new part stack (i.e. a workbook)
to home the
* currentEditorPartPane which hold the active
editor
*/
PartStack newPart =
createStack(editorSashContainer);
editorSashContainer.stack(currentEditorPartPane, newPart);
if (rootLayoutContainer instanceof LayoutPart) {
ILayoutContainer cont =
((LayoutPart) rootLayoutContainer).getContainer();
if (cont instanceof
PartSashContainer) {
// "Split" the editor
area by adding the new part
((PartSashContainer)
cont).add(newPart);
}
}
}
}
3) Here is my converted code that compiles and runs:
void FusionFileOpenAction::splitEditorArea()
{
berry::IWorkbenchPage::Pointer workbenchPage =
m_Window->GetActivePage();
berry::IWorkbenchPart::Pointer part =
workbenchPage->GetActivePart();
berry::IWorkbenchPartSite::Pointer partSite = part->GetSite();
berry::PartPane::Pointer partPane =
partSite.Cast<berry::PartSite>()->GetPane();
* berry::LayoutPart::Pointer layoutPart =
partPane->GetContainer().Cast<berry::LayoutPart>();*
std::list<berry::IEditorReference::Pointer>
editorReferences = workbenchPage->GetEditorReferences();
// Do it only if we have more that one editor
if ( editorReferences.size() > 1 )
{
// Get PartPane that correspond to the active
editor
partSite =
workbenchPage->GetActiveEditor()->GetSite();
berry::PartPane::Pointer currentEditorPartPane
= partSite.Cast<berry::PartSite>()->GetPane();
berry::EditorSashContainer::Pointer
editorSashContainer;
berry::ILayoutContainer::Pointer
rootLayoutContainer = layoutPart->GetContainer();
if (
rootLayoutContainer.Cast<berry::LayoutPart>().IsNotNull() )
{
berry::ILayoutContainer::Pointer
cont = rootLayoutContainer.Cast<berry::LayoutPart>()->GetContainer();
* if (
cont.Cast<berry::EditorSashContainer>().IsNotNull() ) //
ViewSashContainer?*
{
editorSashContainer =
cont.Cast<berry::EditorSashContainer>();
}
}
/*
* Create a new part stack (i.e. a workbook)
to home the
* currentEditorPartPane which hold the active
editor
*/
berry::PartStack::Pointer newPart =
editorSashContainer->CreateStack();
editorSashContainer->Stack(currentEditorPartPane, newPart);
if (
rootLayoutContainer.Cast<berry::LayoutPart>().IsNotNull() )
{
berry::ILayoutContainer::Pointer
cont = rootLayoutContainer.Cast<berry::LayoutPart>()->GetContainer();
if (
cont.Cast<berry::PartSashContainer>().IsNotNull() )
{
// "Split" the editor
area by adding the new part
cont.Cast<berry::PartSashContainer>()->Add(newPart);
}
}
}
}
5) In order to make the code compile, I had to change a getPart() to
GetContainer() (see first 2 bolded lines). The problem actually occurs
in the 3^rd bolded line. Instead of acquiring an object of type
EditorSashContainer, I end up with an object of ViewSashContainer.
Please help provide general information as well as specific solutions.
If I can understand the architecture better, I can solve my own problems.
Sincerely,
Joe Giacomini
