Hello,

I used the control HexView to view a file, here is the code:

main.cpp:



#include <CtrlLib/CtrlLib.h>
#include <HexView/HexView.h>

using namespace Upp;

struct StringHexView : HexView {
	String str;
	
	virtual int Byte(int64 addr)
	{
		return addr < str.GetCount() ? (byte)str[addr]: 0;
	}

	void SetString(String s)
	{
		str = s;
		SetTotal(str.GetCount());
	}

	StringHexView()              {SetTotal(0); }
};


class HexViewer : public TopWindow {
public:
	typedef HexViewer CLASSNAME;
	HexViewer();
	StringHexView  hex;
};

HexViewer::HexViewer()
{
	Add(hex);
	
	Zoomable().Sizeable();
	
	hex.HSizePosZ(36, 36).VSizePosZ(32, 12);
	hex.SetString( LoadFile(GetExeFilePath()));
}

GUI_APP_MAIN
{
	HexViewer().Run();
}

upp file:

uses
	CtrlLib,
	HexView;

file
	main.cpp;

mainconfig
	"" = "GUI SSE2";
