This file contains the base IControl implementation, along with some base classes for specific types ...

IControl * SetTooltip(const char *str)

Set a tooltip for the control.

double GetValue(int valIdx=0) const

Get the control's value.

The lowest level base class of an IGraphics context.

virtual void DrawConvexPolygon(const IColor &color, float *x, float *y, int nPoints, const IBlend *pBlend=0, float thickness=1.f)

Draw a convex polygon to the graphics context.

virtual void DrawRoundRect(const IColor &color, const IRECT &bounds, float cornerRadius=5.f, const IBlend *pBlend=0, float thickness=1.f)

Draw a rounded rectangle to the graphics context.

virtual void FillRoundRect(const IColor &color, const IRECT &bounds, float cornerRadius=5.f, const IBlend *pBlend=0)

virtual void HideMouseCursor(bool hide=true, bool lock=true)=0

Call to hide/show the mouse cursor.

A base class for knob/dial controls, to handle mouse action and Sender.

void OnMouseDown(float x, float y, const IMouseMod &mod) override

Implement this method to respond to a mouse down event on this control.

void OnMouseUp(float x, float y, const IMouseMod &mod) override

Implement this method to respond to a mouse up event on this control.

Control to test drawing polygons.

void OnMouseDown(float x, float y, const IMouseMod &mod) override

Used to manage color data, independent of draw class/platform.

Used to manage mouse modifiers i.e.

Used to manage a rectangular area, independent of draw class/platform.

IRECT GetPadded(float padding) const

Get a copy of this IRECT with each value padded by padding N.B.
