L_VecDlgEditObject

#include "lvdlg.h"

L_LVDLG_API L_INT L_VecDlgEditObject(hWnd, pVector, pObject, nType, pObjectDesc, dwFlags, pfnCallback, pUserData)

L_HWND hWnd;	window handle
pVECTORHANDLE pVector;	pointer to a vector handle
const pVECTOROBJECT pObject;	pointer to a vector object
L_INT nType;	object type to edit
L_VOID * pObjectDesc;	pointer to a structure
L_UINT32 dwFlags;	user interface flags for dialog
LVCOMMDLGHELPCB pfnCallback;	pointer to a help callback function
L_VOID * pUserData;	pointer to more parameters for the callback

Brings up the Edit Object dialog. This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.

Parameter	Description
hWnd	Handle of the window that owns the dialog.
pVector	Pointer to the vector handle that contains the object to edit.
pObject	Pointer to the vector object to be edited.
nType	Object type. Possible values are:
	Value	Meaning
	VECTOR_ARC	Arc.
	VECTOR_CHORD	Chord.
	VECTOR_CLONE	Clone object of a vector group.
	VECTOR_CIRCLE	Circle.
	VECTOR_ELLIPSE	Ellipse.
	VECTOR_ELLIPTICALARC	Elliptical arc.
	VECTOR_LINE	Line.
	VECTOR_PIE	Pie section.
	VECTOR_POLYBEZIER	Poly Bezier curve.
	VECTOR_POLYDRAW	Polydraw.
	VECTOR_POLYGON	Polygon.
	VECTOR_POLYLINE	Polyline.
	VECTOR_RASTER	Raster.
	VECTOR_RECTANGLE	Rectangle.
	VECTOR_TEXT	Text.
	VECTOR_VERTEX	3D vertex in space.
pObjectDesc	Pointer to a structure that contains object information about the object to edit. 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, values from pObject will be used to initialize the dialog. When this function returns, if this parameter is not NULL, the structure will be updated with the values entered through the dialog.
dwFlags	User interface flags for dialog. Determines the layout and action of the dialog.
	Value	Meaning
	VECTOR_DLG_AUTO_PROCESS	[0x80000000] Process the vector on OK.
	VECTOR_DLG_ENABLE_HELPBUTTON	[0x00000002] Enable Help button.
pfnCallback	Pointer to an optional help callback function.
	If you do not wish to provide help to this dialog, use NULL as the value of this parameter.
	To provide help to this dialog, use the function pointer as the value of this parameter.
	The callback function must adhere to the prototype described in LVCOMMDLGHELPCB.
pUserData	Void pointer that you can use to pass one or more additional parameters that the callback function needs.
	To use this feature, assign a value to a variable or create a structure that contains as many fields as you need. Then, in this parameter, pass the address of the variable or structure, casting it to L_VOID *. The callback function, which receives the address in its own pUserData parameter, can cast it to a pointer of the appropriate data type to access your variable or structure.
	If the additional parameters are not needed, you can pass NULL in this parameter.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

   if( nRet == SUCCESS ) 
   { 
      /* there was an object under the point, edit it */ 
      nRet = L_VecDlgEditObject(
