Getting X, Y during Cell dragging?

Hi, it's me again Cheesy

I want to move a row from one table to another, or to the same table in a different index position, but I want to visually show the user what's going to happen by temporarily creating a row in the target table under the cursor while draging around. But I couldn't find a way to get the cell pointed, or even the mouse coordinates (during Drag&Drop the MouseMove event is not called). Is there a way with Windows API Roll Eyes

The ideal:
RequestDropInTable(dataType, table, col, row, drop) Grin

PS: this is more important than any of my last requests because it seems there's no turnaround Kiss

Hi,

You can do that by handling the DragOverTable event. Here's a VB example that detects the row under the mouse pointer during drag and drop:

Code
Select All
Private Sub fcx_DragOverTableVB(ByVal table As FLOWCHARTLibCtl.ITableItem, _
	ByVal dataObj As FLOWCHARTLibCtl.IVBDataObject, _
	ByVal docX As Long, ByVal docY As Long, ByVal keyState As Long, effect As Long)

	Dim row As Integer
	row = table.RowFromPoint(docX, docY)
	If row > -1 Then table.CellFillColor(0, row) = vbRed

	effect = vbDropEffectCopy
End Sub

Private Sub Form_Load()
	fcx.RegisterDragDrop
	fcx.DragDropMode = drProgrControlVB
End Sub


I hope that helps,
Stoyan

Hi Stoyo,

DragOverTable doesn's fire when DragDropMode is drRequestAccept, and TableCellStartDrag doesn't fire when DragDropMode is drProgrControl.

Sorry Stoyo, my bad Embarrassed

I think I'm able to do it without using drRequestAccept. I'll be back to you if needed.

Thank you  Smiley
