Hi community,
I am currently implementing a new perspective with which I want to
strip down the GUI as much as possible; similar to a full screen mode.
So only to show a plugin X and the QmitkStdMultiWidget. The
approptiate terms for BlueBerry application framework would be a view
and an editor.
I have found the following explanation great:
http://docs.mitk.org/2015.05/AddFunctionality.html
(Some code snippets on QmitkDicomExternalDataWidget are not shown in
the webpage!)
I already have the additional perspective in place and when I activate
it it shows my plugin X.
However when I restart the application it starts the perspective again
but doesn't show the StdMultiWidget! It remains white, the space is
reserved for it though.
I didn't find a way to hook into the loading process during a restart.
Any hints on that?
If I remember correctly, restoring editors from previous sessions is not
fully functional yet (as you experienced).
As I want to have a full screen I need a way to get back to regular
perspective so I added a button to the plugin X with :
// Switch to default perspective.
QString perspective_id = "my.workbench.app.perspective";
berry::IWorkbenchWindow::Pointer window =
this->GetSite()->GetWorkbenchWindow();
window->GetWorkbench()->ShowPerspective(perspective_id,
berry::IWorkbenchWindow::Pointer(window));
mitk::RenderingManager::GetInstance()->RequestUpdateAll();
This works great and with the latter RequestUpdateAll the perspective
looks good again.
So maybe this is what is missing?
But I don't have a hook to call it! CreateInitialLayout is only called
when the perspective is explicitly triggered, not loaded during
startup because it was activated when the app was closed.
There are hooks for perspective activation etc. but it is probably not
the best way to do what you want. I think there is some logic hidden in
the MITK Workbench which opens a QmitkStdMultiWidgetEditor instance if
there is none and and e.g. a request update all is triggered (something
along these lines).
The complication with restoring editors is that they need an "input" to
be useful. The input for the multi widget is the data storage, which on
startup usually is empty (except if you start the workbench with some
command line args) so restoring the editor doesn't make much sense if it
will be empty anyways.
Then I have to hide the menu bar, status bar and so on. So whenever
the perspective is activated I want to strip down the GUI.
Is there a way to recall PostWindowCreate() and to give it a different
configurer with the parameters what to show?
I don't have a connection between perspective and the workbench window
advisor, do I?
Window advisors are one time hooks and cannot be triggered again for an
existing window.
I have a different proposal: Make the container widget which holds the
views and editors (excluding menu and tool bars etc.) full screen, using
Qt methods (reparenting it, setting the correct window flags, etc.). You
could probably even have a floating/hovering "leave fullscreen" button.
One complication could be the part activation logic, which is triggered
through a global event filter on the QApplication instance, but this
need to be tried out.
This could be implemented in a separate plug-in for any application and
perspective.
Cheers,
Sascha
Ther once was a fullscreen mode but I didn't find it. Any one also
requesting something similar?
