Re: [Project_owners] capturing keypress and handing to default listener

Thanks, but I already tried exactly that. Take a look at the code in my original post where wrote "I've also tried the non-DOMEvent way:"

I really don't understand the event model but I think there can be at most 1 event listener per layer (1 on a cell, 1 on the parent table, ... 1 on the document) but I can be completely wrong.

My aproach with that is:

    var old_onmouseup = window.onmouseup;
    window. (e) {
            foxgameOnMouseUp(e);
            if (typeof old_onmouseup == "function") old_onmouseup(e);
            };
    var old_onkeyup = window.onkeyup;
    window. (e) {
            foxgame_onKeyUpCheck(e);
            if (typeof old_onkeyp == "function") old_onkeyup(e);
            };

Everything on the onLoad event listener, I needed to call the previous listener allways but it is easy to change, this is working between extensions (was a fix to avoid incompatibility with autocopy) but I don't know if it works with a listener added in the web code.

Hi,

I capture keypress events in a dialog. If the keypress is a number, my listener performs an action. If it's not a number, I want the default keypress event listener to process the event. No matter what I've tried, I can't get the default event listener to process the event once my listener has the keypress.

I've tried window.addEventListener("myListener", onKeyPress, false), window.addEventListener("myListener", onKeyPress, true) where myListener is:

function myListener(evt) {
   if (!isNaN( evt.charCode)) { // if user typed a number, select the corresponding tree row
      var row = parseInt(evt.charCode-KeyboardEvent.DOM_VK_0)-1;
      row <= accountsTree.view.rowCount-1 && accountsTree.view.selection.select (row);
  // Shouldn't other event listeners now be called?
}

I've also tried the non-DOMEvent way:

var origOnKeyPress;
function onLoad() {
  origOnKeyPress = window.keypress;
  window.>}

function myListener(evt) {
    if (!isNaN(evt.charCode)) { // if user typed a number, select the corresponding tree row
      var row = parseInt(evt.charCode-KeyboardEvent.DOM_VK_0)-1;
      if (row <= accountsTree.view.rowCount-1)
          accountsTree.view.selection.select(row);
      else
          origOnKeyPress(evt);
    }
     else
          origOnKeyPress(evt);
}

Thanks for any ideas,
Eric
