CGXAbstractControlFactory::CreateControl
virtual CGXControl* CreateControl(UINT nID, CGXGridCore* pGrid) = 0;
nID
Specifies the control id (same as CGXStyle::GetControl)
pGrid
Points to the parent grid.
Return Value
A pointer to the allocated control object.
Remarks
CreateControl is called to instantiate a specific cell type as child of the given grid. In your override of CreateControl, you should check nID to determine which control to instantiate. This is best done with a switch statement.
Please note that some control require additional initialization steps beyond simple construction before the control pointer can be returned. Please refer to the code in Src\Grid\gxfactry.cpp for any additional initialization steps.
Example
The following sample code shows a typical case statement for control instantiation.
CGXControl* CGXControlFactory::CreateControl(UINT nID,
CGXGridCore* pGrid)
{
CGXControl* pControl = NULL;
// Create control on demand
switch (nID)
{
case GX_IDS_CTRL_EDIT:
// Default edit box
pControl = new CGXEditControl(pGrid, GX_IDS_CTRL_EDIT);
break;
case GX_IDS_CTRL_HEADER:
// default headers
pControl = new CGXHeader(pGrid);
break;
}
return pControl;
}
