Converts point from screen coordinates to the Control coordinates.
Syntax
HRESULT ScreenPtToClient([in] POINT* stScreen,
[out] POINT* stClient);
Parameters
- stScreen
- [in] Pointer to POINT containing the screen coordinates.
- stClient
- [out] Pointer to POINT containing the resulting Control coordinates.
Return Value
Returns S_OK if operation was successful or error code in other cases.
Sample
//C#
public int HitTestPage(PDFXEdit._POINTL pt, out PDFXEdit.PXC_Point ptPagePoint)
{
//Converting input data into given structures
PDFXEdit.tagPOINT ptIn = new PDFXEdit.tagPOINT();
ptIn.x = pt.x;
ptIn.y = pt.y;
PDFXEdit.tagPOINT ptRes = new PDFXEdit.tagPOINT();
//Converting screen point to PDFXEdit client point
pdfCtl.Doc.ActiveView.PagesView.Obj.ScreenPtToClient(ptIn, out ptRes);
//And then checking whether it is on page and returning it in page coordinate system if so
return pdfCtl.Doc.ActiveView.PagesView.Layout.HitTest(ptRes, out ptPagePoint);
}
