if it helps for the beginners...
start learning..
Step 1 .the minimal Rolling Eyes ? gui program in U++:
"titleless Window":
#include <CtrlLib/CtrlLib.h>

GUI_APP_MAIN
{
    TopWindow().Run();  //creates, opens and starts pumping messages...
}


2. let's make much more sophisticated- "title1 Window":
#include <CtrlLib/CtrlLib.h>

GUI_APP_MAIN
{
    TopWindow().Title("title1").Run();  //creates window and its title, opens and starts pumping messages...
}


3. "title1 Window, Zoomable,Sizeable":
#include <CtrlLib/CtrlLib.h>

GUI_APP_MAIN
{
    TopWindow().Title("title1").Zoomable().Sizeable().Run();  //creates window and its title, opens and starts pumping messages...
}


4. a) "title1 Window, setRect" this way doesn't work:

#include <CtrlLib/CtrlLib.h>

GUI_APP_MAIN
{
    TopWindow().Title("title1").SetRect(0, 0, 260, 80).Run();  // should create window and its title, open and start pumping messages... but
//error C2228: left of '.Run' must have class/struct/union type
        type is 'void'
}


Why? I don't know. We need to ask the creators...

But it works in the next examples I'm going to put in a different topic. So, watch the space... Cool

Edited:
4 b) "title1 Window, setRect" - it works like this:

#include <CtrlLib/CtrlLib.h>

GUI_APP_MAIN
{
    TopWindow().Title("title1").Run();
    TopWindow().SetRect(0, 0, 260, 80);
}

Because SetRect is method of Ctrl, not TopWindow and it returns "void". Therefore:

TopWindow win;
win.Title("Title");
win.SetRect(0, 0, 260, 80);
win.Run();

Actually, what methods are supposed to return *this for method chaining is debatable. Usually they are "property" methods (or "modifiers") that are used to setup some initial state.
