Value
|
Meaning
|
1
|
Set if left mouse button is down (defined as MK_LBUTTON inside the Windows SDK)
|
2
|
Set if right mouse button is down (defined as MK_RBUTTON inside the Windows SDK)
|
4

Set if middle mouse button is down (defined as MK_MBUTTON inside the Windows SDK)
|
|
xPos
|
Horizontal position, expressed in pixels respect to the client area of the whole user interface of the waveform analyzer, where the mouse generated the notification
|
yPos
|
Vertical position, expressed in pixels respect to the client area of the whole user interface of the waveform analyzer, where the mouse generated the notification
|
nPressPosInPix
|
Number representing the position expressed in pixels where the mouse button was pressed. If the mouse action should have been performed outside of the waveform's area, this parameter would be set to -1.
It's important to note that this parameter doesn't represent the horizontal position on the waveform's visible area (for this you can refer to the xPos parameter) but to the horizontal position in pixels calculated respect to the bitmap representation of the total waveform's width in pixels at the current horizontal zoom factor.
|
nPressPosInMs
|
Number representing the position expressed in milliseconds where the mouse button was pressed. If the mouse action should have been performed outside of the waveform's area, this parameter would be set to -1.
