Default How to Make Momentary Switch?

What's up everybody - it's your pal Space Raiders here with another question.

How would I go about creating a momentary switch? i.e. hold it down and the value is high - release it and the value is low. I tried creating a class inheriting from IVSwitchControl and overriding onMouseDown but it didn't seem to trigger.

Anyway, bye and thanks for the help.

I'm preaty sure that in IPlug1 repo, there is an Example project IPlugControls.
I think the thing you searching for is the IContactControl class used in the project.

Thanks for the response. I appreciate it. I have been using iPlug2 because I thought the old one was out-dated. Do you think it would be best to use iPlug?

I'm still on IPlug 1 with WDL-Youlean for the Cairo features, but would be good to move to IPlug 2 at some point. However, you can use IPlug 2, but look at the older version's examples to see how the momentary button was implemented, and then build your own custom momentary button control.

OK. I checked IControls header file in IPlug2 repo. Looks like this type of control is removed.

This is the class from Youlean WDL - IControl.h:
Code:
// A switch that reverts to 0.0 when released.
class IContactControl : public ISwitchControl
{
public:
  IContactControl(IPlugBase* pPlug, int x, int y, int paramIdx, IBitmap* pBitmap)
    : ISwitchControl(pPlug, x, y, paramIdx, pBitmap) {}
  ~IContactControl() {}

  void OnMouseUp(int x, int y, IMouseMod* pMod);
};
and Implementation of it - IControl.cpp:
Code:
void IContactControl::OnMouseUp(int x, int y, IMouseMod* pMod)
{
  mValue = 0.0;
  SetDirty();
}
Hope you can fit it in your custom control

Thanks for the help everyone.

Code:
class IVSwitchControlMomentary : public IVSwitchControl {
public:
  IVSwitchControlMomentary(
    IRECT bounds,
    int paramIdx = kNoParameter,
    IActionFunction actionFunc = FlashCircleClickActionFunc,
    const char* str = "",
    const IVColorSpec& colorSpec = DEFAULT_SPEC,
    int numStates = 2
  ) :
  IVSwitchControl(bounds, paramIdx, actionFunc, str, colorSpec, numStates){};
  void OnMouseUp(float x, float y, const IMouseMod& mod) override{
    mValue = 0.0;
    SetDirty(true);
  }
};
