#include "ltwrappr.h"

L_INT LVectorWindow::SelectAllObjects(bSelect, pRect)

Selects or unselects objects in a vector. This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.

Parameters

L_BOOL bSelect

Flag that indicates whether to select or deselect one or more objects. Possible values are:

Value Meaning
TRUE Select all objects within the specified rectangle.
FALSE Unselect all objects within the specified rectangle.

RECT * pRect

Pointer to a RECT structure that contains the rectangle in which the selection operation takes place. Pass NULL to operate on all objects in the vector.

Returns

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

Comments

Call this function to select or deselect objects in a vector. If bSelect is TRUE, the function will select objects. If bSelect is FALSE, the function will deselect objects. If pRect is NULL, all objects are affected. If pRect is not NULL, it should point to a valid rectangle. Only objects within this rectangle will be selected, based on the value of bSelect.

The rectangle specified by pRect is given in screen (physical) coordinates.

The current view port, pan position, camera, scale, translation and rotation values are all considered when determining whether the object is within the rectangle.
