// used for storing single-precision floating point x and y window
|
|
// coordinates.

// Summary:
|
|
// XT_RESIZERECT structure is used by the CXTResizeRect class
|
|
// for defining single -precision floating point coordinates of the
|
|
// upper-left and lower-right corners of a rectangle.
|
|
// Example:
|
|
// The following example demonstrates alternate ways to initialize a XT_RESIZERECT structure:
|
|
// <code>
|
|
// XT_RESIZERECT rc1;

|
// rc1.left = 20;
|
|
// rc1.top = 30;

// rc1.right = 180;

// rc1.bottom = 230;
|

//
|
|
// XT_RESIZERECT rc2 = {20, 30, 180, 230};
