Is there no default drag and drop behavior in an e4 application created by e(fx)clipse?
I just created an e4 application by e(fx)clipse following this tutorial, then I added two parts in my application as following screenshot.
And then when I mess around with this application, I found that these two tabs can't be drag and drop. Theoretically speaking, every window/view should be able to be drag and drop in a SWT UI based e4 application. Can anyone tell me how to make window/view drag and drop behavior possible in such an application? Really appreciate it.
Drag and drop is not part of the core of e4.
You must add the appropriate DnD addon to the Add-ons list in the Application.e4xmi to get drag and drop.
For JavaFX this is org.eclipse.fx.ui.workbench.renderers.base.addons.DnDAddon (full entry in the Application.e4xmi should be bundleclass://org.eclipse.fx.ui.workbench.renderers.base/org.eclipse.fx.ui.workbench.renderers.base.addons.DnDAddon). You may also need the cleanup addon bundleclass://org.eclipse.fx.ui.workbench.renderers.base/org.eclipse.fx.ui.workbench.renderers.base.addons.CleanUpAddon
For SWT it is org.eclipse.e4.ui.workbench.addons.dndaddon.DnDAddon
