Hi,

I want to configure an Request print action based on an onKeyDown event. However, I only want it to work for an specific key (i.e. Ctrl or Alt) to let the user be able to write on that component. The component I am working on is a Power Chart, and there are some settings like name assignment and other functionalities that require text input from the user.

I know the event has properties I can access from a Script action (event.altKey) but I dont know how that event action script can trigger the Request Print.

Thanks,  
Danny

> Hi, I am working with a Power Chart component. I wish there was a sliding Trace I want two things: Print the view using component action. X Trace to have values at the time of printing. X Trace only shows values when your mouse cursor is hovering over the chart. Can't print using a button because of this. So, I have configured an onKeyDown event to trigger the RequestPrint action for the Power Chart. This way, whenever you have placed your mouse over the instant you want the X Trac…
