Hello,
I want to catch key events (space bar press, esc, enter, ...) in ZK. On the whole page.
Is this possible?

Thanks Martin

U can catch certain key events in <window>.
Please ref the developer's guide, search "The ctrlKeys Property".this

And U can "Add and Remove Event Listeners to Pages Dynamically", also in developer's guide.
"...
all events of the specified name the are sent to any components of the specified page will be sent to the listener.
..."

Wish above information can help U.

Keyboard events are only possible on input elements.

Try this example.

<window id="win" title="My First Window" border="normal" width="200px" ctrlKeys="#del" onCtrlKey="alert("Del pressed!");">
<label value="Hello, World!"/>
<textbox id="input"/>
<zscript>
          input.focus();
</zscript>
</window>
