#include "ltwrappr.h"
virtual L_INT LVectorDialog::DoModalVectorHitTest(hWndParent=NULL, pHitTest=NULL)
Brings up the Vector Hit Test Options dialog. This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.
Handle of the window that owns the dialog.
Pointer to a VECTORHITTEST structure that contains hit test options. The values present in the structure when the function is called are used to initialize the dialog. If this parameter is NULL when the function is called, the values used to initialize the dialog will come from the vector handle. When this function returns, if this parameter is not NULL, the structure pointed to by pHitTest is updated with the values entered through the dialog.
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
To get the current hit test settings use LVectorBase::GetHitTest.
Hit test settings can also be set by calling LVectorBase::SetHitTest.
The hit test can be performed by calling LVectorBase::HitTest.
