Occurs when the user moves the mouse.
![]() | Type | Description | ||
| Button as Integer | An integer that corresponds to the state of the mouse buttons in which a bit is set if the button is down. | |||
| Shift as Integer | An integer that corresponds to the state of the SHIFT, CTRL, and ALT keys. | |||
| X as OLE_XPOS_PIXELS | A single that specifies the current X location of the mouse pointer. The x values is always expressed in container coordinates. | |||
| Y as OLE_YPOS_PIXELS | A single that specifies the current Y location of the mouse pointer. The y values is always expressed in container coordinates. |
The MouseMove event is generated continually as the mouse pointer moves across objects. Unless another object has captured the mouse, an object recognizes a MouseMove event whenever the mouse position is within its borders. Use the ItemFromPoint property to get the item from cursor. Use the ColumnFromPoint property to get the column from point. Use the DateFromPoint property to specify the date from the cursor. Use the DrawDateTicker property to draw a ticker as cursor hovers the chart's area.
The following VB sample prints the cell's caption from the cursor ( if the control contains no inner cells. Use the SplitCell property to insert inner cells ) :
Private Sub Gantt1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
On Error Resume Next
' Converts the container coordinates to client coordinates
X = X / Screen.TwipsPerPixelX
Y = Y / Screen.TwipsPerPixelY
Dim h As HITEM
Dim c As Long
Dim hit As EXGANTTLibCtl.HitTestInfoEnum
' Gets the item from (X,Y)
h = Gantt1.ItemFromPoint(X, Y, c, hit)
If Not (h = 0) Then
Debug.Print Gantt1.Items.CellCaption(h, c) & " HT = " & hit
End If
End Sub
