Description
The OnMouseDown event is triggered when the user presses a mouse button on the PageLayoutControl. 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 PageLayoutControl (the top left hand corner).
y is the Y coordinate, in pixels, where the mouse button was pressed referenced against the origin (0, 0) of the PageLayoutControl (the top left hand corner).
pageX is the X coordinate, in page units, where the mouse button was pressed referenced against the origin (bottom left hand corner) of the IPageLayoutControl::Page. The values returned are in IPage::Units.
pageY is the Y coordinate, in page units, where the mouse button was pressed referenced against the origin (bottom left hand corner) of the IPageLayoutControl::Page. The values returned are in IPage::Units.
Remarks
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.
