Copy to Clipboard [message #1740357]

We would like to copy some selected data from a table cell to the local clipboard, to insert it to a different application (e.g. MS Word). So, kind of "CTRL-C" on some execAction() (or similar).

Is there anything in Scout we could use?

Certainly! Smile

BEANS.get(IClipboardService.class).setTextContents("Hello");

Note that in the new HTML UI this triggers a popup window with the text to copy, and the user has to press Ctrl-C manually. Unfortunately, we cannot write directly to the clipboard due to security restrictions of the browser. (Writing to the clipboard from JavaScript is not entirely impossible. But when the Scout UI handles the command from the server to write something to the clipboard, it is no longer in a "user action context", and the browser ignores the command. If you want to write to the clipboard directly, you would have to create your own custom widget.)

Regards,
Beat

Ah, thank you. That's ok for us, the dialog is acceptable.
We thought about making some hidden column with the data, and make some bad JavaScript DOM tree computations to get it out of HTML into Clipboard. Well, your one-liner is much better!
Nice!

We want to select one specific value in a table for later copy (CTRL-C). The problems are:
* it's possible to select a complete row, not a single cell - and not the cell's content at all
* if we make a cell editable (you can select a value now and copy!), it is also possible to alter/delete that value! Solution: reload page to display original values again

	private IColumn<?> clickedColumn;

in initPage():

getTable().addPropertyChangeListener(ITable.PROP_CONTEXT_COLUMN, new PropertyChangeListener() {
	@Override
	public void propertyChange(PropertyChangeEvent evt) {
		Object o = evt.getNewValue();
		if (o instanceof IColumn<?>) {
			clickedColumn = (IColumn<?>) o;
		}
	}
});

in the table class:

// determines cell from "clickedColumn" in clicked row
@Override
protected void execRowClick(ITableRow row, MouseButton mouseButton) {
	final ICell cell = row.getCell(clickedColumn);
	LOG.info("Click: " + cell.getText());
	
	super.execRowClick(row, mouseButton);
}

But what exactly can I do with that cell? I cannot make it selectable or anything...

I am not sure to have understood what you mean. But I wanted to react to this statement:

Here is my idea that does not require to reload the page:

You make your table editable, but you ignore the modifications made by the user when the edition is complete (for example if he do CTRL-X to copy the value or if he change it by mistake). Here is how you can do this in your columns:

@Order(1000)
public class NameColumn extends AbstractStringColumn {
	//...
	
	@Override
	protected boolean getConfiguredEditable() {
		return true;
	}
	
	@Override
	protected void execCompleteEdit(ITableRow row, IFormField editingField) {
		// nothing to do.
	}
}

I think this is not a typical usage of the framework but you should obtain the result you want.

Thank you! ... I was so close... in my execCompleteEdit I had the following two lines for reload:

	reloadPage();
	super.execCompleteEdit(row, editingField);

Without them - like in your solution - it works!

But there is a tiny grey triangle in each copyable cell (see your example) - that should indicate a editable filed, right? I'll have to ask the customer for acceptance of that.

But I'm still looking for an easier way: just select an entry in the table for copy with CTRL-C...

We solved this by supplying a context menu entry "copy value". The user can then right click on a cell and copy its content. We are using the clicked column listener same as you do.

One drawback is that the user can only copy the complete cell content and not a part of it. Another drawback is that while it worked perfectly in Scout Mars there are some bugs that need to be fixed for this to correctly work in Scout Neon (which we have submitted to the bugtracker and BSI is working on them).
