How to restrict the minimum size of the window for Eclipse e4 -

i making application based on eclipse e4 framework. wondering how minimal size of application window can controlled. there seems no properties can defined in e4xmi file purpose.

does know how it?

i found thread in eclipse community forum (http://www.eclipse.org/forums/index.php/t/244875/) saying can achieved creating own renderer. how can exactly?

thank :)

assuming using built-in swt renderers, can listen creation of e4 mwindow elements , gain access underlying swt shell. in example listener registered in addon, can add e4xmi.

import javax.annotation.postconstruct;  import org.eclipse.e4.core.services.events.ieventbroker; import org.eclipse.e4.ui.model.application.ui.basic.mwindow; import org.eclipse.e4.ui.workbench.uievents; import org.eclipse.swt.widgets.shell; import org.osgi.service.event.event; import org.osgi.service.event.eventhandler;  public class minsizeaddon {     @postconstruct     public void init(final ieventbroker eventbroker) {         eventhandler handler = new eventhandler() {             @override             public void handleevent(event event) {                 if (!uievents.isset(event))                     return;                  object objelement = event.getproperty(uievents.eventtags.element);                 if (!(objelement instanceof mwindow))                     return;                  mwindow windowmodel = (mwindow)objelement;                 shell theshell = (shell)windowmodel.getwidget();                 if (theshell == null)                     return;                  theshell.setminimumsize(400, 300);             }         };         eventbroker.subscribe(uievents.uielement.topic_widget, handler);     } } 

note, executed mwindow in application, , there can more of them (i.e. when mpart detached mpartstack seperate window). if want limit execution specific mwindows, recommend add tag window in e4xmi , check tag before setting minimum size.
