Check if OnParamChange was made by GUI

[SaschArt]

Can to check if changed parameter on OnParamChange() was made by GUI, mean knob or userPrompt ?

I guess you could set a flag from your GUI control, and check and clear it in OnParamChange().

Thanks,

How can I get the value of the mDown flag in OnParamChange()

class IButton : public IControl {
protected:
	IBitmap mBitmap;

public:
	bool mDown;

public:
	IButton(IPlugBase* pPlug, int paramIdx, int x, int y, IBitmap* pBitmap)
	: IControl(pPlug, &IRECT(x, y, pBitmap), paramIdx), mBitmap(*pBitmap) {}
	~IButton() {}

	bool Draw(IGraphics* pGraphics) {	
		if (mValue > 0.5)
			return pGraphics->DrawBitmap(&mBitmap, &mRECT);
		else return true;
	}
	void OnMouseDown(int x, int y, IMouseMod* pMod) {
		if (!pMod->R) {
			mValue=mValue>0.5 ? 0. : 1.;
		}
		mDown=true;
		SetDirty();
	}
};

I wouldn't recommend to direct access a public variable of your class. If you really need mDown of every object you should do it with a simple setter/getter functions like:

bool GetIsClicked()  {return mDown;}
void UnClick()  {mDown = false;}

else you could rather do it like this:

public:
	IButton(IPlugBase* pPlug, int paramIdx, int x, int y, IBitmap* pBitmap, bool* pIsClicked)
	: IControl(pPlug, &IRECT(x, y, pBitmap), paramIdx), mBitmap(*pBitmap), mDown(pIsClicked) {}
	~IButton() {}

	bool Draw(IGraphics* pGraphics) {	
		if (mValue > 0.5)
			return pGraphics->DrawBitmap(&mBitmap, &mRECT);
		else return true;
	}
	void OnMouseDown(int x, int y, IMouseMod* pMod) {
		if (!pMod->R) {
			mValue=mValue>0.5 ? 0. : 1.;
		}
		*mDown=true;
		SetDirty();
	}
};

Now you have to add the address of a bool variable of your plug to the constructor list when instantiating a control. This will contain the value of mDown. You have to set it to false again after doing your stuff in onParamChange()
...not tested but should work.
