Hi,
At Form level, write trigger for WHEN_KEY_DOWN, check for F10 and put action as NULL.

case Keyboard.DOWN:
sphere.y += 5;
break;
case Keyboard.UP:
sphere.y -= 5;
break;
case Keyboard.LEFT:
sphere.x += 5;
break;
case Keyboard.RIGHT:
sphere.x -= 5;
break;You haven't said what the problem is.
If your keyboard event handlers are not being called, perhaps you need to add the event listeners to some other object.

How to detect key navigation in JTable
Hi,
I have a problem with JTable's events. When the user presses the mouse's left button on a cell, a mouseClicked event is generated, and my program works fine. But when the user moves from cell to cell with the cursor keys or the tab key, no mouseClicked event is generated, and my event code doesn't execute. I have seen listeners like TableColumnModelListener, but I don't want two or more events at the same time: i.e. if I go from cell 1,1 to cell 2,2, I just want one event, not one for the column and another for the row. I just want ONE event for "selection change", originated by mouse or keyboard. What should I use?
I'm using Java 1.4.

How to detect back browser event in javascript?
How to detect browser event in javascript?
Not working for me. Since i love mozilla to use.
Working in IE.
function HandleBackFunctionality(event)
if(window.event)
alert("Browser1");
if(window.event.clientX < 40 && window.event.clientY < 0)
alert("Browser back button is clicked...");
else
alert("Browser refresh button is clicked...");
else
alert("Browser2");
if(event.currentTarget.performance.navigation.type == 1)
alert("Browser refresh button is clicked...");
if(event.currentTarget.performance.navigation.type == 2)
alert("Browser back button is clicked...");
}Firefox doesn't have a catch-all event object (window.event), but you can create event listeners for the objects of interest. I don't know whether the toolbar is one of those; probably not, since why should web pages be able to see what you are doing on the toolbar??
If we discard the idea of looking for events outside of the page and focus on what is happening inside the page, have you looked at this:

How to separate "Key down" event from panel and numerical control
Hi, All
I have a vi proecess key down events for panel and a numerical control in this panel. the application will do:
1. when panel is focused, user can use "up" and "down" key to driver some hardware.
2. when the numerical control has the focus, "up" and "down" key will change it's value as usual.
somehow the second one did not work, because the panel "key down" event was trigger as well when I use "up' "down" key inise the numerical control.
then I used "Key down?" of numerical control to block the "up/down" key. But the first time when I run the Vi, the panel still got triggered one time.
any suggestions on this? test code attached in this post too.
thanks
CQ
Solved!

KeyDown_Up_valuechange.vi 16 KBThis works for me in 2014. In short, you just need to check to see if your numeric has the focus. If it doesn't, then you process the key value. No need for any other event here except for the stop button.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

How to detect mouse click event?
Hello,
I would like to have a vi to detect left, right and no mouse click. I mean that in the vi attached, Button2 should be 0 (no click), 1 (left c.) or 2 (right c.) depending on the event occured in i-1. cycle. My vi is the modyfied version of the one found here:
http://www.ni.com/example/27663/en/
Sometimes it works fine, but another time nothing happens when I click.
I think the main problem is with the execution times at the for loop and event structure.
Could you help me how to deal with the problem?
Thanks you!
Attachments:
mouse1.vi 12 KBHi VampireEmpire,
Your For loop iterates twice. If an event occures during first iteration everything is fine - Button 2 refreshes during second iteration. But what happens when an event occures during second iteration? Does Button 2 have a possibility to refresh?
1. Do you see the problem now?
2. And if you do - do you really need For loop? I would suggest you trying removing it and connecting shift register to the while loop.

This example won't work. nothing happen after pressing ctrl

can any body help me in that?
Thanks
smThis line of your code:
allSeries.selectedIndices = selectedData;
should be this (that's what in the PDF):
allSeries.selectedIndices = selectedData;
Ya gotta copy the sample code correctly...
Also, nothing will happen from the keyboard until you click
somewhere on the chart.
