When I saw Ultimate++ a week ago I've just wanted to start again c++ programming. Great job!

I can't find solution to run animated HelloWorld example only with visible drawing area. Is it possible to do it in convenient way?

Like without window caption and window frame ("decorations")?

Well, one possibility is to use popup window instead of TopWindow. In fact, you can even popup the TopWindow..

GUI_APP_MAIN
{
	HelloWorld hw;
	hw.Title("Hello world example");
	hw.Text(Nvl(Join(CommandLine(), " "), "Hello world !"));
	hw.SetRect(100, 100, 500, 500);
	hw.PopUp();
	hw.Run();
}

However, I must warn you that this is quite system dependent. E.g. in X11, popup windows behave a bit differently (and quite oddly).

Thanks,

hw.PopUp()

is what I need Smile

And about

hw.SetRect(100, 100, 500, 500);

how may I get a whole available screen width and height to put popup window in the right-bottom corner?

May application be aware of events outside such popup window, for example of mouse events (cursor position, etc.)?

Finally! I have found appropriate API Smile

GUI_APP_MAIN
{
	HelloWorld hw;
	hw.Title("Hello world example");
	hw.Text(Nvl(Join(CommandLine(), " "), "Hello world !"));
	Size s = hw.GetMaxSize(); // Maximum available width (cx) and height (cy)
	hw.SetRect(s.cx - 210, s.cy - 110, 200, 100);
	hw.PopUp();
	hw.Run();
}

I tried to something:

-- the basic idea is to work in CtrlCore::Win32::Win32Proc.cpp
-- in message case : WM_NCHITTEST .
-- add this:

UINT test;
test = DefWindowProc(hwnd, WM_NCHITTEST, wParam, lParam);
if(test == HTCLIENT)
{
return HTCAPTION;
}
else
{
return test;
}

-- the problem starts here, any component added to this window does not receive any of the mouse event.
-- so if someone could guide me to workout a solution where i can know that mouse have been clicked in empty area and not in any child controls, then this could really work.

1. Using SetRect.

2. Predefined no. But not that hard to implement within existing U++ interfaces. I assume you want to use "click&drag": Use SetCapture in LeftDown and perhaps setup some flag in instance (sometimes capture alone will do). Then in MouseMove, use SetRect.

thanks solution works ..

final code section (if any one else want to use it Smile

) :

void xyz::LeftDown(Point pos, dword flags)
{
SetCapture();
last_point = pos;
}

void xyz::MouseMove(Point pos, dword flags)
{
if(HasCapture())
{
int tx;
int ty;
int tcx;
int tcy;
tx = this->GetRect().TopLeft().x + pos.x-last_point.x ; //update the x position by adding the difference moved
ty = this->GetRect().TopLeft().y + pos.y-last_point.y ; //update the y position by adding the difference moved
tcx = this->GetRect().Width();
tcy = this->GetRect().Height();

this->SetRect(tx, ty, tcx, tcy); // set window position
this->Refresh();
}
}

on the little note, i don't know if GetRect() ans SetRect() is used in a optimized manner.

??? ---- one thing i want to ask was abt SetCapture(); was that - do we have to do anything like "Un-SetCapture();" in LeftUp().

also i have placed a picture logo on screen, i tried to use Draw Image in Paint(..) but didn't work well (message #12917) so i used ImageCtrl, now that logo is ImageCrtl (i.e. a conrtol) the logo area can not be used as click&drag client area. maybe i'll make a customized caption-bar later on.

anyway the problem here was solved and working.

thanks a lot.

and one more thing .. third day after using ultimatepp, TheIDE i'll say its simply "the Tool" for RAD and far far far better than any other UI tool or MS orignal stuff.
