Remarks
Occurs when a mouse action happens over the TracksBoard window.
This event replaces the usage of the CallbackTracksboardMouseNotif delegate and is only intended for usage with applications developed using Visual Basic 6 (which results unreliable when dealing with delegates and callbacks) and, in order to be enabled, requires a call to the COMEventEnable method with the nEventType parameter set to EVENT_TYPE_EDT_TRACKSB_MOUSE.

Value
|
Meaning

Set if left mouse button is down (defined as MK_LBUTTON inside the Windows SDK)
|
2

|
xPos
|
Horizontal position, expressed in pixels respect to the client area of the whole user interface of the TracksBoard, where the mouse generated the notification
|
yPos
|
Vertical position, expressed in pixels respect to the client area of the whole user interface of the TracksBoard, 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.
