hi,
i'd like to give my Application an icon.
and i'd like to set that icon from within the code of the app, not using layouteditor or image/draw.

(the icon should change according to the state of the app and the icon gets renderd by my own functions )

so, how would i go about doing this?

thanks in advance,
abductee

You can use ImageDraw to draw image and Icon to show a new icon.

aqq2.lay:
----------------------------------------------------------
LAYOUT(aqq2Layout, 200, 100)
	ITEM(Button, ChangeIcon, SetLabel(t_("Icon")).LeftPosZ(52, 104).TopPosZ(44, 36))
END_LAYOUT


aqq2.h:
----------------------------------------------------------
#ifndef _aqq2_aqq2_h
#define _aqq2_aqq2_h

#include <CtrlLib/CtrlLib.h>

using namespace Upp;

#define LAYOUTFILE <aqq2/aqq2.lay>
#include <CtrlCore/lay.h>



class aqq2 : public Withaqq2Layout<TopWindow> {
	void SetIcon();
public:
	typedef aqq2 CLASSNAME;
	aqq2();
};


main.cpp:
----------------------------------------------------------
#include "aqq2.h"


void aqq2::SetIcon()
{
	ImageDraw iw(16, 16);
	iw.DrawRect(4,4,8,8,Color(Random(),Random(), Random()));
	Icon(iw);
}

aqq2::aqq2()
{
	CtrlLayout(*this, "Window title");
	ChangeIcon.WhenPush = THISBACK(SetIcon);
}

GUI_APP_MAIN
{
	aqq2().Run();
}
