I know I've mentioned this before, but this is still really bugging me. I honestly believe that it would be a substantial improvement if ParentCtrl had SetMinSize functionality as in TopWindow:

struct ParentCtrl : public Ctrl {
	virtual Rect   GetVoidRect();
	virtual Size   GetStdSize() const;

	virtual void SetMinSize(Size sz)	{ minsize = sz; }
	virtual Size GetMinSize() const		{ return IsNull(minsize) ? Ctrl::GetMinSize() : minsize; }

	ParentCtrl();
private:
	Size minsize;
};

(StaticCtrl.h)

Rect ParentCtrl::GetVoidRect()
{
	return GetSize();
}

Size ParentCtrl::GetStdSize() const
{
	return GetMinSize();
}

ParentCtrl::ParentCtrl()
{
	NoWantFocus();
	Transparent();
	minsize = Null;
}

(Static.cpp)
If not a modified ParentCtrl, can we at least have a different Ctrl with this functionality in CtrlLib please (MinSizeCtrl or LayoutCtrl)? I'm getting tired of adding it myself Smile

OK. Please check whether I have done some bug adopting it to my tasted a little:


class ParentCtrl : public Ctrl {
	Size minsize;

public:
	virtual Rect   GetVoidRect();
	virtual Size   GetStdSize() const;
	virtual Size   GetMinSize() const;

	void    SetMinSize(Size sz)         { minsize = sz; }

	ParentCtrl();
};

Rect ParentCtrl::GetVoidRect()
{
	return GetSize();
}

Size ParentCtrl::GetStdSize() const
{
	return GetMinSize();
}

Size ParentCtrl::GetMinSize() const
{
	return IsNull(minsize) ? Ctrl::GetMinSize() : minsize;
}

ParentCtrl::ParentCtrl()
{
	NoWantFocus();
	Transparent();
	minsize = Null;
}

BTW:

template<class T>
class WithMinSize {
	Size minsize;

public:
	void SetMinSize(Size sz)	{ minsize = sz; }

	virtual Size GetMinSize() const		{ return IsNull(minsize) ? Ctrl::GetMinSize() : minsize; }

	WithMinSize() { minsize = Null; }
};

No bugs. Thanks.

BTW:

The issue isn't realy having to do it in lots of places (I already have a template), but that there is nothing in CtrlLib that does it. This makes distributing sample code that used it more difficult, and I thought it should be available anyway. Specifically this is necessary for custom layout code that include Layout templates, but can useful in many other situations.

Thanks again.
