Lets say i want to open an child window for dispaying some help context. A help window.

I would like to open this new window by pressing a button on my main TopWindow.

How do i have to create this new Window and how do i have to add some components like labels, buttons, etc. on this new window?

I tried the example with multipe TopWindows but is this the right way to handle windows like this?

I need some basic example on how to create a child windows from a topwindow.

Thanks in advance.

Michael

Hello,

for a help window just use

HelpWindow a;
a.Execute();

For a non modal window see section 22 of http://www.ultimatepp.org/srcdoc$CtrlLib$Tutorial$en-us.html

Hope this can help.

Is there a way to get the topwindow position and then place a new window relative to the main topwindow, like this?

SetRect(mainWndX + 10, mainWndY + 10, 300, 300);

Yes, GetRect(). For this purpose, top-level windows are considered "desktop children".

One thing you need to know, however: TopLevel window positions are positions without "decorations" provided by host-os, means window caption and thick frame are "outside" this position.

Ok, that works.

But how can i use GetRect to get only the position, not the size?

I only want to get the x-pos, the y-pos of the topwindow and set it on the childwindow with SetRect(x-pos, y-pos, 300, 400);

GetRect delivers the complete Position and Size of the topwindow, how can i split these information?

E.g.

Rect r;

Point p(r.left, r.top);
Point p = r.TopLeft();
Size sz = r.GetSize();

etc...

Note: Press Ctrl+Q and type there "Rect". Or go to Rect id in sources and press Alt+J. (Parser is not perfect yet, but usually it works...)

And how can i use it when calling SetRect from a childwindow?

SetRect(mainWnd.GetRect().left + 20, mainWnd.GetRect().top + 20, wndWidth, wndHeight);

didn't work.

What i want to do is to open a new TopWindow which is placed in relation to my mainWindow.

e.g. my mainWindow is placed like this:

SetRect(300, 300, 500, 500);

Then i want to get the position of my mainWindow and place my childWindow e.g. like shown above.

I tried to get the info from the manual etc. but didn't get it right now.

This should work, however, TopWindows are automatically centered.

Call NoCenter for the TopWindow being opened.

If that still does not work, please zip testcase and post here.
