That's correct. You only ever want to open a window as a direct result of a user action (onClick, keypress, etc) otherwise you may run afoul of any popup blocker.
This means that you cannot open a window in a callback. That is asynchronous that is not a direct result of a user action. If you need to open a window to display a generated document (PDF for instance) then you'll have to open the window when the user clicks some button, send the request to generate the document, then manipulate the window. -jason On Sep 1, 2010, at 4:06 AM, hermis wrote: > Whoops... apparently Chrome's pop-up blocker was kicking in :/ > > On 26 Aug, 16:08, hermis <[email protected]> wrote: >> Hello all, >> >> I can't seem to get Chrome to open a new window using the >> Window.open() function. >> >> It seems to work fine if the function is called from a click handler, >> but not when called directly. >> >> Using Firefox and Internet Explorer the following code launches a >> window on load and a new window each time >> the button is pressed. >> >> public void onModuleLoad() >> { >> Window.open("http://www.google.com";, "_blank", ""); >> Window.alert("Opened window"); >> >> Button btn = new Button("Launch Window!"); >> btn.addClickHandler( new ClickHandler() >> { >> >> @Override >> public void onClick(ClickEvent event) >> { >> Window.open("http://www.google.com";, >> "_blank", ""); >> Window.alert("Opened window"); >> } >> }); >> >> RootPanel.get().add( btn ); >> >> } >> >> In Chrome, a window is not launched on load, however when the click >> event occurs, it works fine. > > -- > You received this message because you are subscribed to the Google Groups > "Google Web Toolkit" group. > To post to this group, send email to [email protected]. > To unsubscribe from this group, send email to > [email protected]. > For more options, visit this group at > http://groups.google.com/group/google-web-toolkit?hl=en. > -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
