问题 Is it possible in GWT to had a handler that detects that the knob pf SplitLayoutPanel is been drag or pressed? Thanks for the help. 回答1: I think, you can do it by overriding onResize() inherited method of DockLayoutPanel: SplitLayoutPanel splitLayoutPanel = new SplitLayoutPanel(){ @Override public void onResize() { super.onResize(); Window.alert("resized"); } }; 回答2: You can do this by adding intermediate ResizeLayoutPanels.

问题 I am developing an application network where I want to offer multiple applications to my users with them only having to register/login a single time and use all of the applications with the same login. To achieve this, I created a cookie in which I store the Session ID of the user(which he receives when he logs in). Everytime a user opens up an application, the Launch Module tries to find the cookie and sends a request to the server to check if that session is still valid. When I tested this

问题 I'm trying to create a Packaged App for Chrome using GWT, I need an SQLite DB. I can't seem to find any decent resources on doing this. I've looked at gwt-mobile-webkit, is that the definitive way to use sqlite in gwt? I'm getting errors when I follow their example, it seems it hasn't been updated in awhile. Based on the lack of results I'm thinking I'm not searching for the right thing, any guidance? 回答1: I'd check out gwt-mobile-webkit, or more specifically the Database API. Though the name

问题 I have a weird bug that is popping up in my Ant build. The build works as such: build.xml calls a new buildTargets.xml file, and in that file most of the work is being done. buildTargets.xml creates a bunch of new files in gwt-out/htdocs/** and another directory staging/htdocs/**. Basically, files are being created in gwt-out/htdocs and then copied into staging/htdocs. The error is that only one file is not being copied, and I am getting a java.IO.FileNotFoundException (Access is denied)

问题 I'm creating an user interface using GWT and there're many boxes of double values but when I set some variable which contains more than 3 decimal places my DoubleBox doesn't accept and truncates the number letting just 3 places.
