public interface IARControlEvents
Provides access to events that occur with interaction to the control.
IARControlEvents is the main events interface for the ArcReaderControl. Generally there is no need to explicitly set event handlers, as most development environments will automatically provide event handlers. These events allow you to programmatically listen out for specific things happening inside of the ArcReaderControl such as the mouse being pressed down, or the CurrentView display being refreshed.

void onMouseDown(IARControlEventsOnMouseDownEvent theEvent)
throws IOException,
AutomationException
The OnMouseDown event is triggered when the user presses a mouse button on the Map or PageLayout display area of the ArcReaderControl. Use the event to specify actions that will occur when a given mouse button is pressed.
button specifies which mouse button was pressed. 1 for the left mouse button, 2 for the right mouse button, and 4 for the middle mouse button.
shift specifies an integer corresponding to the state of the SHIFT (bit 0), CTRL (bit 1) and ALT (bit 2) keys. When none, some or all of these keys are pressed none, some or all the bits get set. These bits correspond to the values 1, 2, and 4, respectively. For example, if both SHIFT and ALT were pressed, ShiftState would return 5.
x is the X coordinate, in pixels, where the mouse button was pressed referenced against the origin (0, 0) of the CurrentView (the top left hand corner). x coordinates increase from left to right.
y is the Y coordinate, in pixels, where the mouse button was pressed referenced against the origin (0, 0) of the ArcReaderControl (the top left hand corner). y coordinates increase from top to bottom.
To find the origin of the CurrentView use ViewLeft and ViewTop properties. To convert x and y coorindates in pixels to map units and page units use the IARMap::ToMapPoint or IARPageLayout::ToPagePoint methods.
Use the win32 SetCapture function to continue receiving mouse events (until the mouse is released) when the mouse is moved outside the control's display area. The win32 ReleaseCapture function releases the mouse.

The OnDoubleClick event is triggered when the user releases and presses a mouse button and then presses and releases it again on the Map or PageLayout display area of the ArcReaderControl. If the double click does not occur within the system's double click time limit, the ArcReaderControl will recognise another OnMouseDown event. Otherwise the event sequence is as follows:
OnMouseDown

OnDoubleClick
OnMouseUp
theEvent - The event
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
void onKeyDown(IARControlEventsOnKeyDownEvent theEvent)

The OnKeyDown event is triggered when the user presses a key whilst the Map or PageLayout display area of the ArcReaderControl has focus.
keyCode specifies a virtual key code value of the key pressed on the keyboard. For alpha-numeric keys this corresponds to the ASCII value, for example "A" key returns 65 which is the ASCII value for capital A. Other key codes are F1 to F12 are 112 to 123 respectively.
Shift specifies an integer corresponding to the state of the SHIFT (bit 0), CTRL (bit 1) and ALT (bit 2) keys. When none, some or all of these keys are pressed none, some or all the bits get set.

theEvent - The event
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
void onAction(IARControlEventsOnActionEvent theEvent)
throws IOException,
AutomationException
The OnAction event triggers before an action occurs with the
ArcReaderControl, and provides you with a mechanism for suppressing
the action from taking place or customising the action that will
take place. For example, by default any hyperlinks that are
accessed when the CurrentARTool is the
esriARToolMapHyperlinks tool open in the systems default browser.
You may want to suppress this default action and open the
hyperlinks in a web browser control.
action indicates the type of action taking place.
data supplied as part of the action.
suppressAction specifies a boolean indicating whether the default action will be suppressed. By default the action will not be suppressed
esriARActionMapProperties: Occurs when the user right clicks on a map in the Table of Contents (TOC) and chooses properties from the drop down context menu. The data passed to the event is an ARMap .
esriARActionLayerProperties: Occurs when the user right clicks on a layer in the Table of Contents (TOC) and chooses properties ffrom the drop down context menu. The data passed to the event is an ARLayer.
esriARActionHyperlink: Occurs when the user accesses a hyperlink, either through the CurrentARTool when it is set to the esriARToolMapHyperlink tool, or when accessing hyperlinks through the identify dialog when the CurrentARTool is the esriARToolMapIdentify tool. The data passed to the event is a string representing the URL of the hyperlink.
esriARActionIdentify: Occurs when the CurrentARTool is the esriARToolMapIdentify tool and is used on the CurrentView. The data passed to the event is an array or map coordinates. In the mouse down event of the tool, the array consists of an x and y coordinate. In the mouse up event of the tool, the array consists of the starting x and y coordinates and the finishing x and y coordinates. These four coordinates will be different is the user has tracked a rectangle with the tool. If the user has clicked a point these coordinates will be duplicated.
theEvent - The event
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
