CursorButtonDown Event

CursorButtonDown Event

Occurs when the InkCollector detects a cursor button that is down.

Declaration

[C++]

void CursorButtonDown(
    [in] IInkCursor* Cursor,
    [in] IInkCursorButton* Button
);

[Microsoft® Visual Basic® 6.0]

Public Event CursorButtonDown( _
    Cursor As IInkCursor, _
    Button As IInkCursorButton _
)

Parameters

Cursor

[in] The IInkCursor object that generated the CursorButtonDown event.

Button

[in] The button that was pressed.

Remarks

A button on a pen tip is down when the user lowers the pen to the digitizer and starts tracing a stroke. A button on a barrel is down when the button is pressed.

When you press the right mouse button, you actually receive two CursorButtonDown events — one for right button pressed and one for left button pressed.

This event method is defined in the _IInkCollectorEvents, _IInkOverlayEvents, and _IInkPictureEvents dispatch-only interface (dispinterfaces) with an ID of DISPID_ICECursorButtonDown.

Example

[Visual Basic 6.0]

This Visual Basic 6.0 example demonstrates using event handlers to display the state of the cursor buttons and whether the cursor is in or out of range. This simple application has a text edit control, Text1, where messages appear when events are received.
