KeyPress event from a Grid

[marswe]

Is it possible to add a listener to a Grid and then react when a user press Enter to select a row in a Grid? I know it is possible with a table, but the Grid does not seem to respond to KeyPress event.

Are there any plans to implement KeyPress event on a Grid? This feature is already there on Table, would be helpful in order to be able to select a row in a Grid with pressing enter or similar.

Other features that would be good to have on a Grid is to disable sorting, column size changes and removal of columns.

Are there any plans for these features to be implemented?

What's the plans for Grid? Will the KeyPress event be supported?

I want to be able to select an item in my Grid and open a details screen corresponding to that item using the Enter key. Any way to do this?

Please help me here. I want to start an action when pressing Enter-key in Grid. How do I do, Grid does not support KeyEvent (when using Table this was easy to do). What am I missing, why is this event not supported in Grid?

[staffan]

Ok, I try to promot this one once more, because I've seen a lot Grid related questions, so hopefully someone knows this.

I want to fire a event from a Grid when pressing the Enter key (or any other key). When I used a table there was support for a KeyPress-Event but in Grid there is not. How do I do this?

I'm guessing you'll need to sink key events - look into grid.el().addEventsSunk(Event.KEYEVENTS);

I figured you meant something like this. I still can't get it to work though. Nothing happens when a press the Enter key. I tried to debug but it seams that the event is never fired.

I must admit that the .el().addEventSunk(..) is a little magic to me, but I understand it as this call will add the KeyPress event to my grid?

Maybe someone can help me fill in a little on the theory behind this, maybe getting it easier for me to get it to work..





searchResultGrid

.el().addEventsSunk(Events.KeyPress);

searchResultGrid.addListener(Events.KeyPress, new Listener<DomEvent>() {
publicvoid handleEvent(DomEvent e) {
if (e.getKeyCode() == KeyboardListener.KEY_ENTER) {
fireLoadEvent(sm.getSelectedItem());
}
}
});

I've just got this solution from a friend, so if anyone has the same problem.

Make an instance of the KeyNav class for the target (in this case the Grid).
E.g like this:




KeyNav keyNav =

new KeyNav<ComponentEvent>(searchResultGrid) {

@Override

publicvoid onKeyPress(ComponentEvent ce) {
if (ce.getKeyCode() == KeyboardListener.KEY_ENTER) {
fireLoadEvent(sm.getSelectedItem());
}
}


};



Thanks Erik!
