Occurs when the user dblclk the left mouse button over an object.
| Type | Description | |||
| 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 DblClick event is fired when user double clicks the control. Use the ItemFromPoint method to determine the cell over the cursor. Use the ExpandOnDblClk property to specify whether an item is expanded or collapsed when user double clicks it. Use the ColumnFromPoint property to retrieve the column from cursor. Use the DateFromPoint property to specify the date from the cursor. Use the BarFromPoint property to get the bar from the point. Use the LinkFromPoint property to get the link from the point. Almost all properties that get an object from point supports -1,-1 coordinate that specifies the current cursor position, so no conversion is required for X and Y coordinates.
