Eclipse Hackathon Hamburg – July 2017

We tried an experiment yesterday, it was quite successful. Instead of having just a meeting in the evening, we started at 11 am … eventually, it also lasts till the night :-).

Over the day, we’ve been approx. 20 people. Definitively, we will do it again! Also a big thank to the University of Hamburg and Prof. Dr. Walid Maalej who hosted us:

ChemClipse 0.7.0 released

I proudly announce the official release of ChemClipse 0.7.0!
https://projects.eclipse.org/projects/technology.chemclipse/downloads

But hey, what’s the difference between OpenChrom and ChemClipse?
It’s quite simple: There’s no difference. ChemClipse is the base for the OpenChrom Community and Enterprise Edition. One could compare it to the strategy RedHat runs. ChemClipse is the equivalent to Fedora and the OpenChrom Enterprise Edition the equivalent to RHEL. We as a company have a strong open source and collaboration commitment. We try to migrate as much of our code as possible to the Eclipse Foundation. Currently, we use the following setup:

• ChemClipse (IP reviewed code and release)
• OpenChrom Community Edition (Incubator for new collaborations and projects)
• OpenChrom Enterprise Edition (Commercial service and support for laboratories/customers)

Editor 3.x/4.x – org.eclipse.ui.editorss

I would like to show you how to re-use the Eclipse editor area in an e4 application. Before, I had the problem that the editor disappeared after maximizing views or that Eclipse showed me messages like:


!MESSAGE Exception while dispatching event org.osgi.service.event.Event [topic=org/eclipse/e4/ui/model/application/ApplicationElement/tags/REMOVE] {ChangedElement=org.eclipse.e4.ui.model.application.ui.basic.impl.PartStackImpl@4981d95b (elementId: org.eclipse.chemclipse.ux.extension.msd.ui.partstack.main.2, tags: [active], contributorURI: platform:/plugin/org.eclipse.chemclipse.ux.extension.msd.ui) (widget: CTabFolder {}, renderer: org.eclipse.e4.ui.workbench.renderers.swt.StackRenderer@7b2f8152, toBeRendered: true, onTop: false, visible: true, containerData: 10000, accessibilityPhrase: null), Widget=CTabFolder {}, AttName=tags, EventType=REMOVE, Position=1, OldValue=Maximized} to handler org.eclipse.e4.ui.internal.di.UIEventObjectSupplier$UIEventHandler@5f32ab17
!STACK 0
org.eclipse.e4.core.di.InjectionException: java.lang.ClassCastException: org.eclipse.e4.ui.model.application.ui.advanced.impl.AreaImpl cannot be cast to org.eclipse.e4.ui.model.application.ui.advanced.MPlaceholder
at org.eclipse.e4.core.internal.di.MethodRequestor.execute(MethodRequestor.java:68)
at org.eclipse.e4.ui.internal.di.UIEventObjectSupplier$UIEventHandler$1.run(UIEventObjectSupplier.java:56)


So, here’s the description how to use the editor correctly:

A) Define an Area under “Shared Elements” in the Application.e4xmi:

B) Insert a “Part Stack” called “org.eclipse.e4.primaryDataStack”:

Add the tags:

• newtablook
• org.eclipse.e4.primaryDataStack
• EditorStack
• NoAutoCollapse

C) Import the Area in the fragment.e4xmi:

D) Reference the Area via a Placeholder called “org.eclipse.ui.editorss”:

It’s important that the Placeholder gets the ID “org.eclipse.ui.editorss”. The Area must be referenced in other perspectives via the same placeholder ID “org.eclipse.ui.editorss”.

E) The 3.x editor is used when elements are opened via the “Project Explorer”:

F) The 4.x editor is used when elements are opened via 4.x editor parts:

That’s it!

RCPTT – set a file from the workspace dynamically

I’m quite amazed how powerful RCPTT is!
https://www.eclipse.org/rcptt

Recently, I’ve encountered a problem. The task was to set the path of a file into the file selection dialog, but it should be independent of the currently used test system. The first try was to set the file directly, but the path is hardcoded:


set-dialog-result File "/home/testman/rcptt/HelloWorld.txt"
get-window -class WizardDialog | get-button "Select *.txt" | click


Hence, a better way is to clear the workspace and import the needed files into the workspace before running the tests. Therefore, a context can be created within RCPTT. The workspace is resolved by “workspace:/” in RCPTT. This could be a solution, cause the workspace is created independently – different systems, different locations. Hence, we could try:


set-dialog-result File "workspace:/com.acme.rcptt/HelloWorld.txt"
get-window -class WizardDialog | get-button "Select *.txt" | click


But this won’t work. We should have a look at the ECL commands:

http://download.xored.com/q7/docs/ecl-api/latest

Instead, we can get the workspace location by using the ECL command “get-workspace-location” and concatenate it with the path to our file in the workspace:


set-dialog-result File [concat [get-workspace-location] "/com.acme.rcptt/HelloWorld.txt"]
get-window -class WizardDialog | get-button "Select *.txt" | click


Tadaaa, that’s it!
