I just noticed that a modal PopupPanel blocks click and mousedown events, but it allows the user to trigger contextmenu events against other windows:
https://screencast.com/t/bRM09iCeF This might be working as designed, depending on how you interpret the documentation: http://www.gwtproject.org/javadoc/latest/com/google/gwt/user/client/ui/PopupPanel.html#setModal-boolean- *When the popup is modal, keyboard or mouse events that do not target the PopupPanel or its children will be ignored.* When I subclass onPreviewNativeEvent <http://www.gwtproject.org/javadoc/latest/com/google/gwt/user/client/ui/PopupPanel.html#onPreviewNativeEvent-com.google.gwt.user.client.Event.NativePreviewEvent-> and log the events that it sees, the contextmenu event isn't being reported; maybe it's not considered to be a mouse event? Is there any way for me to optionally include contextmenu in the set of events that get filtered through onPreviewNativeEvent? The sample is a hacked version of the standard GWT Sample project: package com.basis.sample.client; import com.google.gwt.core.client.EntryPoint; import com.google.gwt.dom.client.NativeEvent; import com.google.gwt.event.dom.client.ClickEvent; import com.google.gwt.event.dom.client.ClickHandler; import com.google.gwt.event.dom.client.ContextMenuEvent; import com.google.gwt.event.dom.client.ContextMenuHandler; import com.google.gwt.event.dom.client.MouseDownEvent; import com.google.gwt.event.dom.client.MouseDownHandler; import com.google.gwt.user.client.Window; import com.google.gwt.user.client.ui.Button; import com.google.gwt.user.client.ui.DialogBox; import com.google.gwt.user.client.ui.RootPanel; public class Sample implements EntryPoint { @Override public void onModuleLoad() { final Button popupButton = new Button("Popup"); final Button sampleButton = new Button("Button"); RootPanel.get("nameFieldContainer").add(popupButton); RootPanel.get("sendButtonContainer").add(sampleButton); class MyHandler implements ClickHandler, MouseDownHandler, ContextMenuHandler { @Override public void onClick(ClickEvent event) { Window.alert("onClick " + event); } @Override public void onContextMenu(ContextMenuEvent event) { event.preventDefault(); Window.alert("onContextMenu " + event); } @Override public void onMouseDown(MouseDownEvent event) { if (event.getNativeButton() == NativeEvent.BUTTON_RIGHT) Window.alert("onMouseDown (right) " + event); } } DialogBox popup = new DialogBox(false, true); popup.setText("Modal Dialog"); Button closePopup = new Button("Close"); closePopup.addClickHandler(new ClickHandler() { @Override public void onClick(ClickEvent event) { popup.hide(); } }); popup.add(closePopup); popupButton.addClickHandler(new ClickHandler() { @Override public void onClick(ClickEvent event) { popup.center(); } }); MyHandler handler = new MyHandler(); popupButton.addDomHandler(handler, ContextMenuEvent.getType()); sampleButton.addClickHandler(handler); sampleButton.addMouseDownHandler(handler); sampleButton.addDomHandler(handler, ContextMenuEvent.getType()); } } -- You received this message because you are subscribed to the Google Groups "GWT Users" group.
