L_VecDlgTranslate

Summary

Brings up the Vector Translation dialog.

Syntax

L_LVDLG_API L_INT L_VecDlgTranslate(hWnd, pVector, pTranslation, dwFlags, pfnCallback, pUserData)

Parameters

L_HWND hWnd

Handle of the window that owns the dialog.

pVECTORHANDLE pVector

Pointer to the vector handle that references the vector image to be translated.

pVECTORPOINT pTranslation

Pointer to a VECTORPOINT structure that contains translation values. The values present in pTranslation 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, this parameter is updated with the values entered through the dialog.

L_UINT32 dwFlags

User interface flags for dialog. Determines the layout and action of the dialog.

LVCOMMDLGHELPCB 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.

L_VOID * 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

Comments

If no objects are currently selected in the source vector handle, all of the objects in the vector handle will be translated in the dialog.

If there are selected objects inside the source vector handle, only those objects will be translated in the dialog.
