I have a gwt-ext EditorGridPanel, by clicking onto a cell, you can edit its value. The cursor is placed at the beginnig of the cell, but I want to select the whole text in this cell if the user clicks on it. Any idea how I can handle this?
I tried some Listeners etc. but none worked for me yet.
Sorry for my english, with Ext-GWT(GXT) it's posible doing this:
final TextField<String> text = new TextField<String>();
text.setAllowBlank(false);
CellEditor textEditor = new CellEditor(text);
textEditor.addListener(Events.StartEdit, new Listener<EditorEvent>() {
public void handleEvent(EditorEvent be) {
text.setSelectOnFocus(true);
}
});
column.setEditor(textEditor);
configs.add(column);
Just find the way in GWT-Ext, I think will something like this.....I hope this help....

I have an editable GWT Label which shows a strange behavior. That is if I click the text “Add note…” the cursor does not appear until I click a second time. But if I click on the label outside the text the cursor appears on first click. How do I solve that? My guess is that replacing the text also removes the cursor when the cursor is in the text. So how can I get the cursor back on first click?
public class EditableLabel extends Label implements FocusHandler {
public EditableLabel() {
super();
getElement().setAttribute("contenteditable", "true");
getElement().setAttribute("tabindex", "1");
this.sinkEvents(Event.ONBLUR);
this.sinkEvents(Event.ONFOCUS);
addHandler(this, FocusEvent.getType());
setText("Add note...");
}
#Override
public void onFocus(FocusEvent event) {
setText("");
}
}
I think your problem depends on the browser. On FF it works fine for me.
I assume you want to write something, if so try to change Label for TextBox, it should work.
When I select a row in a CellTable which contains several columns, the whole row gets colored in yellow. It does not depend on which area of the row I click (which column of the row).
What I try to do is to keep the selected row colored in yellow as long as no other row of this very table is selected. At the moment, as soon as I click somewhere else in the browser, the row gets back its original color.
I tried to use a selection model, but this changed nothing. Do you have any advise or is this simply not possible, since the focus is managed by the browser? The behavior is the same in the Google showcase for the CellTable...
The selection model actually does what you want to do: it paints a row blue and the row does not change color if you click elsewhere in the page. (Only when another row is selected)
There are 2 selection models:
One that lets you select only one row, and another one that lets you select multiple rows.
MultiSelectionModel<Row> selectionModel = new MultiSelectionModel<Row>();
table.setSelectionModel(selectionModel);
SingleSelectionModel<Row> selectionModel = new SingleSelectionModel<Row>();
table.setSelectionModel(selectionModel);
The solution of user905374 did actually work. I mentioned in my first post that I already tried the solution with a selectionModel and that it did not work. This was partially true. It does work, but only if the table does NOT contain a CheckboxCell.
Following a working and the not working example. I think this might be a bug, but I am not sure if I miss something.
final CellTable<LicenceDto> licenseTable = new CellTable<LicenceDto>();
final SingleSelectionModel<LicenceDto> selectionModel = new SingleSelectionModel<LicenceDto>();
licenseTable.setSelectionModel(selectionModel);
//--- If I add this column, the selection does work.
Column<LicenceDto, String> workingColumn = new Column<LicenceDto, String>(new TextCell()) {
#Override
public String getValue(LicenceDto object) {
return "Works";
}
};
workingColumn.setFieldUpdater(new FieldUpdater<LicenceDto, String>() {
#Override
public void update(int index, LicenceDto object, String value) {
;
}
});
licenseTable.addColumn(workingColumn);
//--- If I add this column, the selection does NOT work anymore.
Column<LicenceDto, Boolean> notWorkingColumn = new Column<LicenceDto, Boolean>(new CheckboxCell(true, true)) {
#Override
public Boolean getValue(LicenceDto object) {
return object.getEnabled();
}
};
notWorkingColumn.setFieldUpdater(new FieldUpdater<LicenceDto, Boolean>() {
#Override
public void update(int index, LicenceDto object, Boolean value) {
presenter.enableLicense(object, value);
}
});
licenseTable.addColumn(notWorkingColumn);
You can even combine multiple cells and add them to the table (e.g. LinkActionCell etc). As long as there is no CheckboxCell, the blue selection with the SingleSelectionModel does work like a charm. Does anyone see what I do wrong with this CheckboxCell or is there a bug?
UPDATE
It was simply a usage error of me. The problem was that I set handlesSelection to true (second parameter of the CheckboxCell constructor) even thought I don't handle anything. Setting it to false solves the problem.
Bottomline: Use a selection model (e.g. SingleSelectionModel) and do not set the handlesSelection parameter to true of the CheckboxCell constructor to true, if you don't handle the selection by yourself.
You should observe the Showcase demo again. This time use the checkbox on the left most column i.e the first column. On selection the row turns blue indicating the row selection is made. This is when you have SelectionModel set up. Click on the page anywhere outside the CellTable/DataGrid the selection is not changed.
Now, instead of choosing the row via checkbox from first column, you click on a row in any other column. The row turns yellow. Click on the page anywhere outside the CellTable/DataGrid the focus/yellow is lost.
"colored in yellow" indicates row is under focus and being edited and not selected.
Note - you can force row selection by using click events per cell.
Try something like this:
CellTable table;
YourDataObject object = new YourDataObject(...);
SingleSelectionModel<YourDataObject> selectionModel =
new SingleSelectionModel<YourDataObject>();
table.setSelectionModel(selectionModel);
...
table.setSelected(object, true);
Use MultiSelectionModel if you wish more than one line to be highlighted.
Store the selected row's index. When user selects row, change row's style to some "selected-style" appropriate for your case (defined in your css file) and remove selected style from the previously selected row. Also don't forget to update selected row's index.
If you provide some code from the original version I help you out with some code with pleasure.
I'm trying to update the particular row of a cellTable without loading the page when clicking a button, which is in the same row.
I just want to update the Column1 which is a TextColumn. I want to Change the text of the particular column.
Can anyone help me?
Thanks in Advance,
Gnik
If you want to redraw the whole row, you can use:
celltable.redrawRow(absIndex);
But if you want to update a single cell and performance is important you could do this in a child class of CellTable
public void updateCellContent(int absRowIndex, int cellIndex, String innerHtml) {
TableRowElement tr = getChildElement(absRowIndex);
if (tr != null) {
TableCellElement td = tr.getCells().getItem(cellIndex);
if (td != null) {
td.setInnerHTML(innerHtml);
}
}
}
I suppose you use a ListDataProvider to store as it is used in the showcase example here.
In that case you just have to up change the data in the ListDataProvider and when its done just call
cellTable.redraw();
And don't worry the table doesn't flicker when doing that :)
Take a look at https://stackoverflow.com/a/7109021/787660
When you use the ListDataAdapter and add your row like in the example using the ListWrapper (don't be scared, you use it like a List-Object) the refresh is automatically triggered.
I love an Emacs feature to copy selection to clipboard automatically. Is it possible to do the same on Eclipse?
Environment: Windows XP, Helios
To copy a String from Eclipse to the clipboard, you can use
void copyToClipboard (String toClipboard, Display display){
String toClipboard = "my String";
Clipboard clipboard = new Clipboard(display);
TextTransfer [] textTransfer = {TextTransfer.getInstance()};
clipboard.setContents(new Object [] {toClipboard}, textTransfer);
clipboard.dispose();
}
Then you can call this method from a MouseAdapter or KeyAdapter, depending on where you want to get your String from. In your case it could be MouseAdapter, which listens to doubleclicks, gets the current cursor position of the text, marks the word and then adds the String to the clipboard.
edit to answer a question: You can set up your own MouseAdapater and attach it to buttons, text fields or whateer you like. Here's an example for a button:
Button btnGo1 = new Button(parent, SWT.NONE);
btnGo1.setText("Go");
btnGo1.addMouseListener(new MouseAdapter() {
#Override
public void mouseDoubleClick(MouseEvent e) {
//do what you want to do in here
}
});
If you want to implement mouseUp and mouseDown events, too, you can just add MouseListenerinstead of the Adapter. The only advantage of the Adapter is, that you don't have to override the other methods of the interface.
Since the original question was to automatically get the selection of the text of an editor: the way to get the selection from an editor is explained here.
You can try this plugin. Along with auto copy points mentioned in Eclipse show number of lines and/or file size also addressed.
I have one small problem i.e. one textbox is their when click on the text box the popup is shows below the text box.The popup contains celltable
i write keypresslisner for textbox when i press Down And UP arrow the focus is set to be cellTable And also we still press down and up arrows its highlites the rows in celltable
anyone please tell me how to solve it...it's my request
When I wrote code like this:
box.addKeyPressHandler(new KeyPressHandler() {
#Override
public void onKeyPress(KeyPressEvent event) {
if (event.getNativeEvent().getKeyCode() == 38) {
celltable.setFocus(true);
} else if (event.getNativeEvent().getKeyCode() == 40) {
celltable.setFocus(true);
}
}
});
only the focus is goes to the cell table
The question is a little bit unclear, but I think you may be helped by FocusPanel:
http://google-web-toolkit.googlecode.com/svn/javadoc/2.0/com/google/gwt/user/client/ui/FocusPanel.html
Wrap your CellTable in this FocusPanel and you can do setFocus() on that instead. The FocusPanel has addKeyPressHandler(), so you can capture further keypress events there, also when your textbox has lost the focus.
