How do get Key arrow down / up event in table?

Hi,
I'm using a qx.ui.table.Table with qx.ui.table.model.Simple. How can I register to be notified when somebody scrolls up/down the table with the 'The Up Arrow key' or 'The Down Arrow key' keys? The current table line is nicely highlighted but I can't find out how to get the events. (I don't mean scrolling in the scrollbar but directly in the table). Thanks for some enlightment, Marcel ------------------------------------------------------------------------------ Come build with us!

Have you tried listening to a generic "keypress" event and then checking
for the two keys you're interested in? T.

Here is a code snippet for others to reuse: /** * Get notification when user scrolls up/down with Up or Down Arrow Keys * @param {qx.event.type.KeySequence} e Event on key press * e.getType() = "keypress" * e.getKeyIdentifier() = "Down" for Arrow down * e.isShiftPressed() = true if Shift was pressed * e.getCurrentTarget() = qx.ui.table.Table * @see http://demo.qooxdoo.org/current/apiviewer/#qx.event.type.Dom * @see http://demo.qooxdoo.org/current/apiviewer/#qx.event.type.KeySequence~getKeyIdentifier * To remove again (must be called on same object): * var success = table.removeListenerById(this.keypressListenerId); */ this.keypressListenerId = table.addListener("keypress", function(e){ this.debug("Event keypress e=" + e + " identifier=" + e.getKeyIdentifier() + " isShiftPressed=" + e.isShiftPressed()); var ident = e.getKeyIdentifier(); if (ident == "Up" || ident == "Down") { var rowNum = table.getFocusedRow(); // ... } }, this); > T. > > Marcel Ruff wrote: > >> Hi, >> >> I'm using a qx.ui.table.Table with qx.ui.table.model.Simple. >> >> How can I register to be notified when somebody >> scrolls up/down the table with the 'The Up Arrow key' or 'The Down Arrow >> key' keys? >> The current table line is nicely highlighted but I can't >> find out how to get the events. >> (I don't mean scrolling in the scrollbar but directly in the table). >> >> Thanks for some enlightment, >> >> Marcel >> >> ------------------------------------------------------------------------------ >> Come build with us!
