SetGadgetRotation

Core

SetGadgetRotation changes the specified Gadget's rotation factor in radians. Scaling is determined from the upper-left corner of the Gadget and is applied dynamically during painting and hit-testing. The Gadget's logical rectangle set by SetGadgetRect does not change.

When rotation is applied to a Gadget, the entire subtree of that Gadget is rotated. To remove any rotation factor, use 0.0.

BOOL SetGadgetRotation(
    HGADGET hgadChange,         // Gadget to change
    float flRotationRad)        // New rotation factor in radians
);

Parameters

hgad: [in] Gadget to change
pflRotationRad: [in] New rotation factor in radians
