Class CornerResizer

Namespace
PluginUI
Assembly
PluginUI.dll

Resize grip for the bottom-right corner of a resizable editor (iPlug2 ICornerResizerControl). Dragging asks the container for a new pixel size through RequestResize(int, int); the DAW (or the standalone window) decides and calls back SetPixelSize(int, int). Hidden when the host is not resizable. Double-click restores the preferred size.

public class CornerResizer : Control
Inheritance

Inherited Members

Remarks

Place it last in a Canvas (or align it bottom-right in any panel) so that it stays on top. The drag works in screen pixels, so it stays stable while the content rescales under the pointer.
