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 3rd 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
