gwt

问题 I have recently started developing another GWT module. So I created a package with all my new classes and one specific class that implements a new entrypoint. I modified in my gwt.xml to my new entrypoint. When I compile, I get the following error: GWT Compiling client-side code. WARNING: 'com.google.gwt.dev.GWTCompiler' is deprecated and will be removed in a future release. Use 'com.google.gwt.dev.Compiler' instead. (To disable this warning, pass -Dgwt.nowarn.legacy.tools as a JVM arg.)

问题 Is there a way to encode a String with UTF-8 in GWT? In other words, is there a GWT-compatible equivalent to java.net.URLEncoder.encode(toEncode, "UTF-8")? 回答1: Yes, it's com.google.gwt.http.client.Url.encode(), JavaDoc: http://google-web-toolkit.googlecode.com/svn/javadoc/1.6/com/google/gwt/http/client/URL.html 来源： https://stackoverflow.com/questions/1139698/encode-string-with-utf-8-in-gwt

问题 Is there a way to set the cusror position in GWT RichTextArea. There is method setCusrorPosition() to do so in TextArea, but not in RichTextArea. Perhaps there is a native JavaScript (called from GWT) that could set the cursor position in the RichTextArea? 回答1: You are right RichTextArea is not providing the setSelectionRange method, but i have created one using the JSNI. Below is the method, public native void setSelectionRange(Element elem, int pos, int length) /*-{ try { var selection =

问题 I tried the following code: RootPanel root = RootPanel.get("root"); root.clear(); final FlowPanel p = new FlowPanel(); root.add(p); for (int i=0; i<20; ++i) { String url = "/thumb/"+i; final Image img = new Image(url); img.addLoadHandler(new LoadHandler() { @Override public void onLoad(LoadEvent event) { p.add(img); } }); Image.prefetch(url); But it does not work for me. Did I missed something? 回答1: Image load handler is called only in the case, when image is attached to the DOM. So you have

问题 I am using Cell Table in GWT.In that cell table I am adding these columns. TextColumn<Document> idColumn = new TextColumn<Document>() { @Override public String getValue(Document object) { return Long.toString(object.getId()); } }; TextColumn<Document> refColumn = new TextColumn<Document>() { @Override public String getValue(Document object) { return object.getReferenceNumber(); } }; /* * DateCell dateCell = new DateCell(); Column<Contact, Date> dateColumn * = new Column<Contact, Date>

问题 we are currently developing some kind of enterprise resource managment system with Google Web Toolkit. Our main goals are to keep our system extend able, modular and our costs low. We choose PostgreSQL as our database, because Oracle and MySQL are just too expensive. However we have most experience with Oracle. We also need some kind of replication for our database. The Server backend will be written in Java. We are now looking for a good database abstraction. We were thinking of Hibernate,

问题 I would like to shorten very long descriptions to the available table column width. I have the column width information in pixels. Now I would like to convert this measure to the number of characters, so I can shorten the text to the specified number. I doesn't have to be 100% correct, a near assumption will also work. 回答1: Wrap your text in the cell in a DIV. This will tell you whether the text inside the DIV is larger than the cell: <div id='test' style='width:200px;height:100px;overflow

问题 Is it possible to build a tree table like this with the new CellTableBuilder of "vanilla" GWT ? The GWT Showcase example only allows to expand the "top level" rows. My use case requires expansion of multiple row levels. How can I achieve this with pure GWT ? 来源： https://stackoverflow.com/questions/16584386/build-tree-table-with-gwt-celltablebuilder
